Agenda 05/27/2014 Item #16D 4 5/27/2014 16.D.4. EXECUTIVE SUMMARY Recommendation to approve the five-year update of the Final Management Plan for the Conservation Collier Otter Mound Preserve. OBJECTIVE: To obtain approval from the Board of County Commissioners (Board) for the 5-year update for the Otter Mound Preserve Final Management Plan. along with direction for its implementation. CONSIDERATIONS: The Otter Mound Preserve, located in Marco Island. FL, has been in County ownership since 2007. A Final Ten-year Management Plan was developed and approved by the Board on 1/15/08, Agenda Item 16E. The approved plan has been operational for the Otter Mound Preserve since that time. The Conservation Collier ordinance 2002-63, as amended, in section 14.3, directs that "Ten-year Plans shall be updated at least every 5 years." The attached plan has been updated pursuant to that direction and includes budget changes in keeping with the approved Conservation Collier Financial Plan (4/8/14, Agenda Item 11B). Changes are shown in underline-strikethrough format so that they can be readily identified. The major change in this land management plan is the addition of a Tree Management Plan (Appendix 1 1). The Conservation Collier Land Acquisition Advisory Committee reviewed the updated plan and unanimously recommended approval at its public meeting held on 11/18/13 (Agenda Item VI.A.3.). FISCAL IMPACT: There is no new fiscal impact associated with approving this management plan update. Funds for any additional Tree Management services required were retained - $2.000 annually - out of reductions related to staff performing chemical treatments for exotics instead of contracting this out. Management costs are consistent with the Board-approved Conservation Collier Financial Plan. GROWTH MANAGEMENT IMPACT: There is no growth management impact associated with this item. LEGAL CONSIDERATIONS: This item is approved for form and legality and requires a majority vote for Board approval. —JAB RECOMMENDATION: That the Board approves the attached proposed Five-year Final Management Plan for Conservation Collier's Otter Mound Preserve and directs staff to implement the updated plan.

The entire preserve site is a Calusa shell mound(c.700 A.D.-1200 A.D.)that contains artifacts of both archaeological and historical significance. Access to the preserve is from Osceola Court and Addison Court- with 4-space public parking available including handicapped space public parking available within the Addison Court right of wavat the entrance. The Conservation Collier Program acquired the bulk of the preserve in July 2004 and the southwestern-most "Karen"property in June 2007, The Karen property has been incorporated into the existing preserve;therefore,this plan applies to both properties,and both properties are collectively referred to as the Otter Mound Preserve. Largely comprised of native, tropical hardwood hammock species, the preserve also contains examples of non-native, historical vegetation. The Conservation Collier Program manages this parcel under authority granted by the Conservation Collier Ordinance 2002-63,as amended(available from www.municode.com)with assistance from the City of Marco Island under an Interlocal Agreement signed February 28,2006(Appendix I)and renewed in October 2013. (Appendix 1) Conservation,restoration, and passive public use are the designated uses of the property. Management activities allowed are those necessary to preserve and/or restore this environmentally and historically endangered land for the benefit of present and future generations. Public use of this site must be consistent with these goals. An initial site assessment of the preserve was conducted on September 22,2003 and the northernmost section was purchased by the Conservation Collier Program on July 12,2004. Previously known as the"Gionet Otter Mound" property for the former owners—Ernest and Gladys Otter and Michael,Mary,and Gary Gionet—it was renamed Otter Mound Preserve in May 2005. On June 18,2007,the southernmost part of the preserve was purchased from Harvey and Lisa Karen. Initial preserve activities are identified in Table 1 below. This Plan is being updated in 2013 to provide current preserve information and to add a recently developed Tree Management Plan to the Otter Mound Land Management Plan.

This text is a working document that establishes the foundation for the ten-year plan by identifying the appropriate management techniques necessary to preserve and/or restore the resource. considering budget needs. This plan will seek to balance resource restoration and protection with passive public recreational and educational use while looking at restoration needs, budgetary needs, listed species protection, archaeological/historical feature protection, and invasive exotic plant and species maintenance. This plan is divided into sections that incorporate an introduction;descriptions of the natural and cultural resources;projected uses of the property; and management issues,goals,and objectives. This management plan will be submitted to the Conservation Collier Land Acquisition Advisory Committee(CCLAAC) and the Collier County Board of County Commissioners(BCC)for their approvals. When approved by the BCC, this plan will replace superscede the Interim Final Management Plans prepared by Conservation Collier staff in September 2001 (Gionet section) and July 2007 (Karen .ection)January 2008 and approved by the Board of County Commissioners on January 15.2008(Agenda Item 16E). 1.2 Location Formatted:tent Otter Mound Preserve is located at 1831 Addison Court within the City of Marco Island, in Collier County, Florida. Lying in the middle of the semi-circle formed by East,West and South Inlet Drive, the preserve is bound on the north by Addison Court and on the southwest by Ocseola Court. The site location is shown in Figure 1. The legal description is attached as Appendix 2.

The Conservation Collier Ordinance 2002-63, as amended (available from www.municode.com) identifies these specific habitats and gives preference to them in acquisition evaluations. These habitats include, in order of preference: tropical hardwood hammock, xeric oak scrub, coastal strand, native beach,riverine oak,high marsh(saline),and tidal freshwater marsh. Otter Mound Preserve was purchased because it contains tropical hardwood hammock habitat. In addition, the preserve contains the following features that make it an important archaeological and historical site: undisturbed Calusa shell mounds,a historic pioneer structure(outhouse), and historic man-made shell terracing that runs along the northern and western sections of the property. The location of the preserve in the urban area provides an opportunity for citizens, visitors, and school-age children to view this habitat type without traveling far. The preserve serves as an important stopover site for a variety of migratory bird species,and it is home to the Florida tree snail (Liguus fasciatus) — a Florida Fish and Wildlife Conservation Commission(FFWCC) Species of Special Concern. In addition,Otter Mound Preserve contains seven state listed plant species: Curacao bush (Cordia globosa), giant wild pine (Tillandsia utriculata), Florida thatch palm (Thrinax radiata), Satin leaf(Chrysophvllum olivifotme), Red stopper (Eugenia rhombea), Lignum vitae (Guaiacum sanctum), and barbed-wire cactus (Acanthocereus tetragonus). The protection and management of these listed species and their habitat is critical to their long-term existence in Collier County and in Florida. 1.4 Nearby Public Lands and Designated Water Resources The closest preserve to Otter Mound is Rookery Bay National Estuarine Research Reserve (RBNERR), a 110.000-acre preserve surrounding Marco Island. Other preserves, in order of increasing distance,are identified in Table 2 below.

Under the Conservation Collier Ordinance, the Collier County Conservation Collier Program holds management authority for all Conservation Collier Program lands. The City of Marco Island assists with specific management tasks for Otter Mound Preserve, as identified in the Interlocal Agreement(Appendix I). 1.6 Public Involvement Neighborhood involvement will be sought through direct mailing notice for public meetings to residents within the surrounding area, owners of properties that border the preserve, and organizations with an interest in the preserve (City of Marco Island, Marco Island Historical Society, Southwest Florida Archaeological Society,Archaeological and Historical Conservancy, Inc.). Any major changes or management activities that are likely to be intrusive or in some way affect neighboring properties will be reviewed with these contacts prior to conducting the activity. Staff will also seek volunteers through these contacts(Appendix 3). Conservation Collier Program 7 Packet Page -1073- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve 2.0 Natural and Cultural Resources 2.1 Physiography 2.1.1 Topography and Geomorphology A review of a United States GeologicialGeological Survey(U.S.G.S.) 7.5 Minute Series map of the Marco Island area and on-site investigation reveals that a slight mounding exists on the preserve. The elevation is generally between 10 and 15 feet National Geodetic Vertical Datum (NGVD) for most of the site(Lucas & White 2004). Portions of at least six linear depressions ("canals') and six ridges are present in the southwestern portion of the preserve. The middle of the preserve is elevated, relatively flat ground. The eastern side of the preserve contains a complex of elevated knolls and lower zones resembling the central parts of most large shell mounds found in the region. Four deep,historic borrow pits of unknown origin also exist within the eastern section of the preserve(Figures 4 and 5). Fill from these pits was most likely used to create Caxambas Village roadways. 2.1.2 Geology The geology of the area is characterized by aboriginal shell deposits adjoining and intergrading with surrounding mangrove peat deposits. The peat deposits, in turn, intergrade and interlayer with marine marls, coastal sand deposits, and naturally occurring shell bar formations that are deposited and altered by sea level fluctuation, storm surge activity, and other coastal energetic:energetic activity. At even greater depths the Holocene deposits give way to elements of the Pleistocene Caloosahatchee formation and various Wisconsian sand terrace features. These marine marls or calcified "muds" contain lenses and deposits of clay intermixed with varying percentages of sand(Beriault&Can 2000). 2.1.3 Soils Soils data is based on the Soil Survey of Collier County, Florida (USDA/NRCS 1990, rev. 1998). Mapped soils on the preserve show the entire area to be urban land—aquents complex, organic substratum. This soil consists of urban land soil materials that have been dug from different areas in the county and have been spread over organic muck soils for coastal urban development(Lucas&White 2004). Otter Mound Preserve lies on a slight topographic high that is associated with a Calusa shell mound. Shell mound soils are composed of shells and shell fragments with an organic component derived from forest litter. The soil generally is circurn-neutral to slightly alkaline (pH=7-8)and contains 1-20%organic materials. The loose collection of shells allows water to drain extremely rapidly. The calcareous substrate and coastal location of shell mounds often permit tropical or subtropical species of plants to grow much further north than their normal Irange on other substrates permits [Florida NatualNatural Areas Inventory (FNAI) & Florida Department of Natural Resources(FDNR) 1990]. Figure 6 shows the substrate profile of one 3- meter trench dug by the Archaeological and Historical Conservancy, Inc. at Otter Mound Preserve.

Water does not pool in any area of the site,even after heavy rain events. Water management does not appear to be an issue at the site. 2.2 Climate Otter Mound Preserve is located in an area of Florida that is overlapped by a humid subtropical climate and a tropical savanna climate in which temperatures are moderated by winds from the Gulf of Mexico and the Atlantic Ocean. A tropical savanna climate is characterized by sharply delineated wet and dry seasons and average monthly temperatures greater than 64° Fahrenheit. Monthly rainfalls may exceed 10 inches during the wet season. Humid subtropical climates are characterized by less extreme rainfall fluctuations between wet and dry seasons and average monthly temperatures less than 64°Fahrenheit in some months. The average annual temperature for the coastal portion of Collier County is approximately 75° Fahrenheit. The warmest months are usually July and August. The humidity is high during these months,but frequent afternoon thunderstorms prevent excessively high temperatures. Two-thirds of the annual rainfall occurs in the wet season, which is from May to October. Thunderstorms are frequent during the wet season, occurring on average every two out of three days between June and September. Rainfall records for the area indicate that there is no significant variation in the annual rainfall throughout much of the county; however, large variations often occur within a single year. The hurricane season extends from June through November,with peak activity occurring in September and October when ocean temperatures are warmest(URS 2007). 2.3 Natural Communities Table 3: Summary of Natural Communities • FNAI Natural Community Type #Acres %of Global State Comments Area Rank Rank Shell Mound 2.46 100% G2 S2 3 gopher tortoise burrows located,0 live gopher tortoise seen Florida tree snail population present 2.3.1 Shell Mound Otter Mound Preserve consists entirely of Shell Mound, as defined by FNAI &FDNR (1990). This natural community type, synonymous with tropical hardwood hammock, is largely a result of the activities of the Calusa, instead of natural physical factors. Shell Mound is generally characterized as an elevated mound of mollusk shells and aboriginal garbage on which a hardwood, closed-canopy forest develops. Their coastal, usually insular, location generally protects Shell Mounds from fire, but subjects them to marine influences, including high winds, hurricanes, salt spray, high insolation, and storm surge. Typical shell mound plants include: gumbo-limbo_(Bursera simaruba), cabbage palm (Sabal palmetto), mastic (Sideroxylon Conservation Collier Program 12 Packet Page-1078- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve foetidissimum), red cedar (Juniperus virginiana), hackherry (Celtis occidentalis), live oak (Otter-ells virginiana), Florida privet (Forestiera segregata), coral bean (Erythrina herbacea), marlberry (Ardisia escallonioides), saffron plum (Sideroxylon celastrinum), coontie (Zamia pumila),and others. The species vegetation composition on Otter Mound Preserve varies slightly. While no red cedar, saffron plum, or coontie are present, species such as soapberry (Sapindus saponaria), strangler fig (Ficus aurea), Jamaican dogwood (Piscidia piscipula), and yellow elder(Tecoma stans) are common. The previous use of the preserve as an early 1900's home-site also led to the introduction of many non-native species such as: mango (Mangifera indica), royal poinciana (Delonix regia), guava (Psidium guajava), oyster plant (Tradescantia spathacea),air potato(Dioscorea bulbifera),coral vine(Antigonon leptopus),and others. Aerial photographs from 1952 show that much of the present day preserve was wooded, while surrounding parcels were almost completely cleared. More recent development in the 1960s further affected the surrounding lands(Figure 7). Figure 7: Historic Aerials _ . „:_,..,,„ ,N-'''' .:., -`:: ,,.

Subsequently, in October 2005, Hurricane Wilma passed through Marco Island. The combined effect of invasive exotic removal and Hurricane Wilma damage resulted in 0h canopy coverage in some sections of the preserve. During June and July of 2006,331 native plants(85 trees, 87 shrubs,and 159 groundcovers)were planted within the barest areas of the preserve(Figure 9). A planting list is attached as Appendix 5. Irrigation supplement gel was planted with each plant to aid in establishment because no irrigation was available at the preserve. The gel,consisting of 95% water and 5%cellulose,was planted with the root ball of each plant and provided supplemental irrigation for approximately 30 days. All the soil material within each plant hole was sifted and surveyed for artifacts by members of the Southwest Florida Archeological Society. All artifacts that were found are housed at the Collier County Museum in Naples. Because of the archaeological nature of the site, only plants in 3 gallon pots or smaller were planted. As a result,canopy coverage in the northern section of the preserve has been slow to recover,despite a high planting survival rate(Figure 8). { s P 4 liko a, yy. p y h ..' +� / fir, . -,.. 114 v!!f I fa tt.,. . � J/ ft "mot es *'�"4 --sa `w• , yr °Aw+-,y, '.' .. `� .ti.�� ' -'y� y' ;r:'" �i °•'" e i, ,+M p 4 ;"''r.

Conservation Collier Program 17 Packet Page-1083- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve 1 One hundred and twenty-seven(127)plant species have been recorded as occurring at Otter Mound(Appendix 6). Data were collected by botanist James N.Burch,PhD. in January, February,and July 2007. Of these 127 species,93(73.2%)are native to the site and 34(26.8%) are exotic. Occurrences of fauna at the preserve are based on direct visual and aural observations by Collier County personnel during site visits, evidence of activity such as spoor, scat, or burrows, and available site information. Mammal species known to occur or individuals and/or evidence of activity directly observed within the preserve include the Virginia opossum (Didelphis virginiana), nine-banded armadillo (Dasypus novemcinctus), raccoon (Procyon lolor), and eastern gray squirrel (Sciurus carolinensis). Neighbors reported seeing a bobcat at the preserve in 2009. Bird observations by Collier County staff are included in Table 4. Fifty-seven different species of birds have been observed to date.

It lists 62 bird species that have been recorded as confirmed, probable, or possible breeding in the vicinity of Otter Mound Preserve (in the Marco Island USGS quadrangle). These species are listed in Appendix 7. Reptile and amphibian species observed at the preserve include brown anole (Anolis sagrei), green anole(Anolis carolinensis), southern black racer(Coluber constrictor priapus),ring neck snake (Diadophis punctatus), and greenhouse frog(Eleutherodactylus planirostris). Neighbors have also reported observing coral snakes(Micrurus fulvius)near the property. Invertebrates observed at the preserve include cloudless sulphur butterfly (Phoebis sennae), eastern tiger swallowtail butterfly (Papilio glaucus), whip scorpion (Mastigoproctus giganteus), Florida tree snail(Ligtus fasciatus),and various wasp species. Other wildlife species that have not been recorded undoubtedly occur at Otter Mound Preserve. During migration periods, transient bird species utilize this area for short periods of time. The developed character of the adjacent properties may inhibit transient use by many mammal, reptile, and amphibian species, thus possibly limiting the utilization of the preserve to resident individuals or inhibiting the dispersal of many species to and from the preserve. 2.5 Listed Species 2.5.1 Listed Plant Species There are 7 plant species at Otter Mound that are listed by the Florida Department of Agriculture and Consumer Services,5 as Endangered and 2 as Threatened. FNAI lists 1 species as Critically Imperiled in Florida,and 2 species as Imperiled in Florida. There ere neis one species listed as Endangered or Threatened by the U.S.Fish and Wildlife Service(Table 5).

This plan t Lir Additional rare plant species may be found at Otter Mound Preserve following further field surveys.Confirmation of rare plant identifications will be made by a qualified botanist. 2.5.2 Listed Wildlife Species Listed wildlife species observed onsite include the Florida tree snail (Liguus fasciatus) and brown pelican (Pelecanus occidentalis). Although, no live gopher tortoises (Gopher-us polyphemus)have been observed on site, three gopher tortoise burrows have been located. One crushed,dead gopher tortoise was observed near the center of the preserve in July 2005. A map has been prepared by staff showing locations of existing gopher tortoise burrows;however, it is not appended to this plan to protect the burrows from disturbance. A brief description of observed species and their status is included in the following paragraphs. 7.4 Florida Tree Snail(Liguus fasciatus) This large land mollusk - a species of Special Concern in Florida-is generally found on smooth- barked trees in native hammocks. The color 4 '":� patterns of the Florida tree snail are extremely a-. variable. At this time, there are 58 named color "- forms in south Florida and the Florida Keys . (Davidson 1965;Jones 1979),with others in Cuba. } The yearly life cycle of the Liguus begins in the spring with the first warm rains. Eggs hatch and :- = '" t adult snails "wake" up from their aestivation (hibernation). The snails grow,mate, and lay eggs from spring thru fall, mid to end of May through November. Aestivation usually begins around the first cool weather in October or November. These events can be triggered or stopped by localized weather conditions(Power 2005). SightinLrs of Florida Tree Snails have become fewer, with none sighted in 2014. The preserve has been dealing with some kind of unknown pest for Conservation Collier Program 19 Packet Page -1088- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve several years.which may he one reason for fewer sinhtinos.

America southward to northern South America. Brown Pelicans - are found in shallow warm coastal marine and estuarine waters, ( particularly on sheltered bays (Shields 2002). These birds n 'r occasionally use Otter Mound Preserve as a resting area Brown Pelican(Pelecanus occidentalis) Photo by Michael Costello Within Otter Mound Preserve, FNAI has no documented occurrence of any listed wildlife species (Appendix 4). However, the FNAI database report indicates that 20 listed species have the potential to occur at the preserve based on their known or predicted range.

Of these, 10 are considered Category I -Invasive and 7 are considered Conservation Collier Program 20 Packet Page-1089- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve Category II -Potentially Invasive by the Florida Exotic Pest Plant Council (FLEPPC) (FLEPPC Plant List Committee 2007)(see Table 7). The most problematic invasive plant species at Otter Mound are Brazilian pepper (Schinus terebinthifohus), air-potato (Dioscorea bulbifera), and bowstring hemp (Sansevieria hyacinthoides). Large amounts of Brazilian pepper were removed from the western section of the preserve in June 2005. Air potato and bowstring hemp are present throughout the preserve and are being maintained. Most of the other species in Table 7 are not yet problematic or only slightly problematic on the site. A program of exotic removal and maintenance at the preserve has reduced most exotic plant occurrences to minimal,however coral vine remains problematic. Under certain conditions, especially following soil disturbance or drainage, some native plant species can become invasive.There are no native plants species at Otter Mound Preserve that are currently a management problem on the site.

" rx* The preserve was also once part of Caxambas Village. In the ,��) -�* >,,r w< early 1900's Caxambas Village was a thriving community which grew with the Marco Island clamming industry. Jim and K*, Tommie Barfield, influential citizens in the history of Marco Historic Outhouse at time of Island, once owned the property that is present day Otter acquisiton Mound. They sold it to Charles Griner and his wife in 1919. Photo by Doug Suitor Prior to 1950, Ernest and Gladys Otter, would vacation in Caxambas Village, spending the winters at the Griner's home. Eventually Mrs. Griner sold the property to the Otters after her husband's death in 1950. By all accounts, the whelk shell terracing throughout the preserve was constructed by Mr. Otter sometime in the 1940s,50s and 60s. It has been reported that Mr. Otter used ancient Calusa whelks (Busycon sp.)that he found buried in and around his property to construct the shell terracing. (Beriault&Can 2000) A house built in 1923 once stood near the center of the preserve. The home,which was occupied by the Otters until 1977, burned down in 1978. The only structure left within the preserve is a historic out-house located approximately 75-feet north of the old home-site.

Previous owners had cleared and fanned much of the land,planting mango,guava,avocado,and Surinam cherry trees that are still present on the property. A home built in the 1920s occupied the site until it burned down in 1978. An old outhouse is the only structure left in the preserve. Nearly all the surrounding land immediately outside the preserve boundaries has been developed with single family homes. 3.2 Current Public Use and Land Uses The preserve is currently open to the public for use of a walking trail. Three large interpretive signs that present the history of the preserve have been installed along the trail. Small plant identification signs have also been placed within the preserve. These signs are intended to educate visitors and school-age children about the preserve. Planned Public Uses and Assessment of Impacts Easements, Concessions, and Leases — There are two easements associated with Otter Mound Preserve. The first easement,as described in Collier County Subdivision Plat Book 39 pages 96 and 97(Figure 10)and approved by Marco Island City Council on October 7,2002 as Resolution 02-31, is a 4,051 square foot historical preservation easement along the northwestern boundary of the preserve encompassing a portion of the man-made shell wall and the land surrounding it (Figure 11).

The easement is solely for the purposes of ingress/egress and is described in the deed of the adjacent property owners(Figure 13). The full deed is attached as Appendix 8. The access road associated with the ingress/egress easement is currently unpaved; however, the easement does not prohibit future paving. Conservation Collier staff will work with the present and future adjacent property owners to encourage them to maintain the easement using only pervious materials. Landscaping Large, dense native species will be planted along the western property line, and perhaps along the eastern property line, to screen the neighboring houses from the preserve. All planting will be coordinated with a qualified archaeologist. In 2011. it was discovered that neighbors along the east side of the preserve had encroached into the preserve boundary approximately 10-15 feet with landscape plants. After discussions with the neighbors. it was decided to remove the landscape plantings and re-plant native shrubs and trees in this area. An archeologist was onsite during the plantings. The artifacts recovered included shell net weights,pottery shards, and fish and animal bones. Thirty-five(35) 7-gallon native plants were installed within the cleared encroachment area_ including: pigeon plum (Coco/oba diversifolia), red stopper(Eugenia rhombea). mvrsine (Rapanca punctata) and wax mvrtle (Mvrica ceri/era). All but the wax myrtle survived, and additional seeds from existing Riving humili.c plants were scattered.which grew to fill in much of the empty space.

Conservation Collier Program 29 Packet Page -1098- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve 3.3 Adjacent Land Uses Single-family residential developed lots surround the preserve on all sides. A paved road, Addison Court,runs along the entire north edge of the preserve,and a shell hash road extension of Osceola Court, runs through the southwestern edge of the preserve within the ingress/egress easement. 3.4 Prospective Land Acquisitions Jim and June Dyches nominated their property to Conservation Collier in August 2007 for consideration in Conservation Collier Acquisition Cycle 5. The property is adjacent to Otter Mound Preserve along the southeastern border.and contains a single family home.There are no prospective additions to the preserve at this time. 4.0 Management Issues, Goals and Objectives 4.1 Program Framework and Goals The Conservation Collier Program considers properties of high natural resource value throughout Collier County for acquisition from willing and voluntary participants.Properties must support at least two of the following qualities to qualify for further consideration: rare habitat, aquifer recharge, flood control, water quality protection, and listed species habitat. The Collier County Board of County Commissioners (BCC) appointed a Land Acquisition Advisory Committee to consider any selected or nominated properties that an owner has indicated a willingness to sell. The committee recommends property purchases for final approval by the BCC. Acquisitions were halted by the Board of County Commissioners in 2011 and remaining acquisition funds have been shifted to the Land Management Trust Fund. In April 2014. the Conservation Collier Land Acquisition Advisory Committee was transitioned into the Conservation Collier Advisors, Committee. This committee will provide public oversight for management of Conservation Collier lands. This property will be managed only for protection/restoration of natural and historical/archaeological resources and for passive, outdoor public recreation that will be compatible with the protection/restoration of the site and surrounding lands. 4.1.1 Management Activities to Protect/Restore the Resource "Each property purchased by Conservation Collier shall have its own management plan. The ordinance requires that an `Interim' Management Plan be developed within 60 days of purchase and that a `Final' management plan be developed within two years. After that, property management plans must be updated every five years.Interim plans shall be concerned with basic items such as removal of invasive exotics and trash, establishing site security, developing management partnerships, and planning for public access. All management plans must be approved by both the Conservation Collier Advisory Committee (CCAC) and the Board of County Commissioners." Conservation Collier Program 30 Packet Page-1099- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve In February, 2013, a Tree Management Plan was drafted to provide a foundation for documentation, protection and management of the native tree species at Otter Mound Preserve and to identify. prioritize, and eliminate potentially hazardous conditions for visitors and surrounding property owners. The plan was provided by mail to neighbors in early 2013,giving them a month for comment. Out of 10 packets sent out. 5 neighbors responded positively, with no response from the rest. The Tree Management Plan is attached as Appendix 11 and will become a part of the overall Land Management protocol upon approval of this Management Plan Update by the Board of County Commissioners. 4.1.2 Manager The Site Manager for Otter Mound Preserve will be a designated Collier County Environmental Specialist. 4.1.3 Preserve Rules and Regulations No dumping, use of unauthorized vehicles, or removal or destruction of natural or historical/archaeological resources will be permitted within the preserve. The goal is to allow limited non-destructive public access to native plant communities and animal species. Currently, the preserve rules are those identified in Collier County Ordinance 76-48,as amended(available from www.municode.com). An Preserve Use ordinance (Ord. 2011-38) specifically for the Board of County Commissioners for approval during 2008 was developed by the Conservation Collier Land Acquisition Advisory Committee and approved on October 11. 2011 (Agenda item 8E)by the Board of County Commissioners to administer public use of preserves. 4.2 Desired Future Conditions This section includes a description of the proposed future conditions for the site's natural areas. Management techniques to achieve these conditions are outlined in section 4.4. After managers complete recommended management actions,Otter Mound Preserve will consist of tropical hardwood hammock habitat that has a similar structure and composition to that which existed prior to modem settlement in the late 1800s. With the exception of the trail,the site will be heavily vegetated with appropriate mature native vegetation that will provide suitable cover for a variety of wildlife species. The main canopy will be comprised of gumbo limbo,soapberry, and mastic. Mid-story will consist of a variety of natives including stoppers, black-bead, marlherry, wild coffee, and firebush. Groundcover will be native and will include rouge plant, scorpion tail,and blue porterweed. Some non-natives will remain in the preserve, depending upon their historical significance and relative invasiveness. Historic non-native, invasive plants will be limited to contained management areas along the trail and removed from all other areas of the preserve. 4.3 Major Accomplishments During Previous Years Table 9:Major Management Accomplishments during previous years Accomplishment Year(s) Initial removal of invasive exotic vegetation 2005 Conservation Collier Program 31 Packet Page -1100- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve Hurricane Wilma debris clean-up 2006 Development of management agreement with City of Marco Island 2006 Native plant planting days(over 300 plants planted) 2006 US Fish and Wildlife Service grant for invasive exotic plant maintenance 2006 Development of 1,000-foot trail with a representative sidewalk portion built to be accessible to 2006-2007 wheelchairs Florida Humanities Council grant for historic interpretive signs and post/rope fence 2006-2007 Formal ceremony to open preserve for passive public use 2007 Native plant restoration project(471 trees,shrubs and around cover plants planted) 2009 Eastern boundary encroachment cleared and replanted(7 trees.2.1 shrubs) 2011 Tree Manauement Plan Developed.Supplemental plantinu at north east corner(f shrubs) 2013 4.4 Goals and Objectives for 10 year period A set of goals and objectives for Otter Mound Preserve were developed in conjunction with the drafting of this Management Plan. The goals and objectives in this plan are tailored specifically for Otter Mound Preserve based on the purposes for which the lands were acquired,the condition of the resources present, and the management issues for the property. On-site managers should be familiar with this entire Management Plan. Goals and objectives from the interim management plan for the Otter Mound Preserve were reviewed to determine whether they should be included in this plan. The goals and objectives presented here reflect programmatic goals and ideas of Conservation Collier personnel in charge of managing and protecting the area. These goals shall not be modified, but specific application of management techniques may take into consideration input by user groups and other stakeholders from outside the program, accommodating user needs and desires where practicable and where overarching management goals are not violated. Management issues are discussed below in separate sections.Within each section,approaches for dealing with these issues are described. The ability to implement the specific goals and objectives identified in this plan is dependent upon the availability of funding resources. The following goals have been identified for Otter Mound Preserve: Goal 1: Maintain the property in its natural condition prior to modern development. Goal 2: Eliminate or reduce human impacts to indigenous plant and animal life. Goal 3: Maintain the trail to provide a safe and pleasant visitor experience. Goal 4: Protect Archaeological,Historical and Cultural Resources. Goal 5: Facilitate uses of the site for educational purposes. Goal 6: Provide a plan for security and disaster preparedness GOAL 1: MAINTAIN THE PROPERTY IN ITS NATURAL CONDITION PRIOR TO MODERN DEVELOPMENT Action Item 1.1 Remove populations of exotic plants to restore natural habitats. Because of the severity of the infestation, the invasive exotic vegetation within Otter Mound Preserve ewere treated in phases to avoid non-target damage to sensitive and recruiting native plant species. Currently. exotic plants constitute a small (5% or less) component of the vegetation community. The densest and most invasive species will he treated first (Phase 1). Once the extent of these'`Phase 1"species is evaluated and deemed to be at a manageable level, Conservation Collier Program 32 Packet Page-1101- 5/27/2014 16.D.4. 2013 Updated Land Management Plan-Otter Mound Preserve "Phase 1". In addition, aSome examples of invasive exotic plant species that are deemed to be historic may be left along the trail,visible to visitors(Table 10). Table 10:Otter Mound Preserve Invasive Exotic Plant Species Control Plan Scientific Name Common Phase Historic Recommended Control Name Antigonon leptopus coral vine 1 X Vines should be carefully foliar sprayed with glyphosate or cut and the root end sprayed with glyphosate if they are growing over the top of native vegetation. Herbicide application only works to knock hack growing vegetation. The tubers need to he removed to kill this plant. Broussonetia paper 1 Large trees should be cut, stumps treated papyrifera mulberry with triclopyr, and trees removed from site or chipped on site and added to the mulched trail. Small trees and re-growth should be cut, the stumps treated with triclopyr, and the debris should remain on site if it is not extensive. Basal treatment may be used;however,it is not recommended near sensitive natives or native seedlings. Dioscorea alata air-potato 1 The vines should be cut and the root end sprayed with triclopyr if they are growing • over the top of native vegetation.

Removal of royal poinciana will be conducted over time.pursuant to the Tree Management Plan, and as funding-allows.to avoid creating large canopy gaps. Because of the sensitivity of the native trees within the preserve, Imazapyr (i.e. Arsenal herbicide) or any other herbicide that demonstrates high soil persistence and is readily absorbed from the soil by plant roots will not be used at Otter Mound Preserve. • Action Item 1.2 Manage the property for the benefit of native and listed wildlife species. Management actions to protect native bird species: Avoid off target damage to native plants and animals,especially rare species,during invasive exotic plant treatments. Prohibit unleashed domestic animals from being brought onto the preserve lands. A population of Florida tree snails exists at the preserve. Historically, the major causes of Liguus colony mortality have been habitat destruction and commercial exploitation of their shells. Pesticide spraying for mosquito control may also affect their survival (Emmel&Cotter 1995). Management actions to protect Florida tree snails: Protect and restore existing hammock vegetation. Protect against collection — a sign will hehas been posted along the trail proclaiming all plants and animals in the preserve are protected. Reduce pesticide effects through increased tree canopy. Reducing mosquito pesticide applications within the preserve is not a tangible goal because the preserve is located in a dense residential area. However,; 2reasedmaintaining—canopy and mid-story cover Conservation Collier Program 34 Packet Page -1103- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve should reduce some effects of the pesticide by physically blocking the amount of pesticide entering the preserve via aerial spraying. Three gopher tortoise burrows have been located in the preserve and one deceased tortoise was observed on the property in July 2005. It is unknown whether this individual tortoise was re- located to the site by a human or naturally recruited to the site on its own. Currently, no gopher tortoises are known to inhabit the preserve. Because of growing developmental pressures and the limited availability of natural areas, Conservation Collier and City of Marco Island staff contacted FFWCC staff to evaluate whether Otter Mound Preserve would serve as an adequate gopher tortoise relocation site. FFWCC staff have expressed that they would be extremely reluctant to deem a heavily vegetated tropical hardwood hammock as an acceptable gopher tortoise relocation site(Appendix 9). Action Item 1.3 Restore native vegetation as appropriate and necessary. Monitor native plant recruitment and re-growth in areas of invasive exotic removal and/or hurricane damage. *Plant appropriate native vegetation to restore tree canopy coverage to 85%-95%and understory density to 50%-75%. *All plantings should be done during rainy season in accordance with the Action Items set forth to attain Goal 4: Protect Archaeological, Historical and Cultural Resources. Supplemental irrigation may also be necessary with plantings. Action Item 1.4 Monitor need for and success of management. Conduct periodic wildlife surveys - While some wildlife data has been collected, additional baseline data should be collected, especially on invertebrates, small mammals, reptiles, and amphibians. The Preserve Manager may contract this work out or enlist the assistance of local educators to coordinate student research projects. Wildlife sampling should take place at regular intervals(2-4 years)to detect long-term trends. A complete plant inventory was completed for the preserve in 2007. A new plant inventory by a qualified botanist should be performed every 2-45 years. or as landing allows. to detect long-term trends. Install permanent photo points—Five photo points have been established at random locations on the property. Photo point locations are marked with small white plastic signs and rebar, and their positions have been recorded with a GPS. All photo points will be taken annually at a standard height and angle of view. GOAL 2: ELIMINATE OR REDUCE HUMAN IMPACTS TO INDIGENOUS PLANT AND ANIMAL LIFE AND ON HISTORICAL/ARCHAEOLOGICAL RESOURCES. Action Item 2.1 Maintain bollards at north trail entrance to prevent unauthorized vehicle access. Action Item 2.2 Identify locations of rare native plant species. Conservation Collier Program 35 Packet Page -1104- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve Action Item 2.3 Enforce regulations prohibiting trash and landscape debris dumping in or near the preserve. Action Item 2.4 Encourage visitors to stay on trail with signs and fencing. Action Item 2.5 Identify actual and potential locations of resident animal life and take steps such as locating visitor amenities away from animal nesting sites. Action Item 2.6 Avoid non-target damage to native plants and animals,especially rare species,during invasive exotic plant treatments. Action Item 2.7 Note and research all site development occurring adjacent to Otter Mound Preserve to determine that the proper site development permits have been obtained and that the site development complies with the permits. All existing local, state, and federal regulations should be strictly followed and enforced during any site development adjacent to the preserve. It shall be the responsibility of the developer to establish erosion control measures and vegetation protection measures(i.e.,protective fencing or barriers). If any site developer working in areas adjacent to the preserve does not take the necessary control measures, construction shall be immediately halted until control measures are put into place and mitigation and/or remediation will be the sole responsibility of the developer. GOAL 3: MAINTAIN THE TRAIL TO PROVIDE A SAFE AND PLEASANT VISITOR EXPERIENCE. Action Item 3.1 Keep trail area open and free of weedy species,debris,and litter. Action Item 3.2 Inspect trail monthly for tripping hazards and fix immediately. Action Item 3.3 Inspect trail monthly for overhead hazards such as broken or hanging tree limbs and fix immediately. Action Item 3.4 Monitor hornets near trail. A population of ground-nesting hornets was observed near the trail. If this population begins to pose a problem to visitors,it should be removed. Action Item 3.5 Keep signs,benches,and post/rope fence in good repair. Action Item 3.6* Empty garbage cans regularly.as needed. At least once a week more if necessary. Action Item 3.7* Mow Addison Court right of way regularly. At least once every two weeks in rainy season;as needed during dry season. Conservation Collier Program 36 Packet Page-1105- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve I *Action Items 3.6 and 3.7 will be the responsibility of the City of Marco Island per Interlocal Agreement-Appendix 1 Action Item 3.7 Keep adjacent trail vegetation lush. The view from the trail should be focused on blocking out the urban environment. Action Item 3.8 Remove vines and weedy vegetation from shell terracing that is in view of the public. Follow guidelines of Action Item 4.7 below. GOAL 4: PROTECT ARCHAEOLOGICAL,HISTORICAL AND CULTURAL RESOURCES. The Archaeological and Historical Conservancy, Inc. included management recommendations in their phase 1 archaeological survey and assessment of the preserve in April 2000. Their recommendations for management of the site stipulated that"efforts should be made to minimize impacts to [the parcel's shell mound]features and the historic shell walls created by Ernest Otter that are found on the north and west sides of the parcel." Also,"the Otter shell walls that terrace the northern and western periphery of the parcel are historically significant and should be avoided during development" (Beriault & Carr 2000). The County will follow these recommendations,as detailed in the Action Items below,and shall cooperate fully with any other direction from the Florida Division of Historical Resources on the protection and management of archaeological and historical resources, per provisions of the Land Development Code Section 2.2.25. The management of the resources present on Otter Mound Preserve will comply with the provisions of Chapter 267, Florida Statutes, specifically Sections 267.061 2 (a) and (b). The collection of artifacts or the disturbance of the archaeological and historic sites within the preserve shall be prohibited unless prior authorization has been obtained from the Collier County Board of County Commissioners and the Department of State,Division of Historical Resources. Action Item 4.1 Limit visitor use of the preserve to designated trail areas. Signage that states, "FRAGILE Please do not walk on shell walls and terracing" and post and rope fencing have been placed along the trail in the most sensitive areas of the preserve to encourage visitors to stay on the trail. Action Item 4.2 Replace--Remulch the i-u4e; a—trail • • . •• •. • • p fisesevery 3 years or as needed.: shell has Until the mulch trail can be replaced, areas containing mulch will he maintained. Efforts will be made to utilize mulch from removed royal poinciana trees and downed tree debris by grinding this material on site and spreading it on the trail. In 2013_the trail was remulched with mulch made from removed Royal Poinciana trees Action Item 4.3 Prohibit bicycle use within the preserve. Bicycle riding is listed on the prohibited activities sign, and a bicycle rack is located at the entrance of the preserve to encourage visitors to park their bikes. Conservation Collier Program 37 Packet Page -1106- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve Action Item 4.4 Prohibit managers and contractors from walking within 6 feet of the edge of the shell terrace walls unless absolutely necessary. These areas are extremely fragile and subject to erosion. Action Item 4.5 Prohibit planting near the edge of the shell terracing walls. Plant groundcovers and shrubs a minimum of 6' from the edge of the walls. Plant trees a minimum of 10' from the walls. All planting must be coordinated with a qualified archaeologist. Action Item 4.6 Prohibit mechanical removal of vegetation using machinery. Invasive exotic vegetation will be cut and stump sprayed with herbicide or foliar sprayed with herbicide. No plants or trees will be pulled out by the roots unless coordinated with a qualified archaeologist. If native or invasive exotic debris is to be removed from site, large limbs will not be dragged across the floor of the preserve. Large limbs will be cut into manageable sections and carried so as not to disturb the surface substrate. Action Item 4.7 Allow only minimal,careful weed/vine control along the shell walls. Foliar spray vines and weeds. Once dead,carefully cut and/or brush dried vegetation away from walls. Live or dead plants will not be pulled out of shells. Action Item 4.8 Maintain/restore historic outhouse structure. Staff, in conjunction with a qualified historical architect, will assess and determine how best to restore and maintain the outhouse. . as funds allow Recommendations from the historical architect will be used to guide a qualified contractor (County staff, contractor, or volunteer) to make repairs and maintain the outhouse to the reasonable extent that management funds allow. A sign stating,"HISTORIC STRUCTURE do not disturb" is displayed in front of the outhouse, which is located near the trail behind the post and rope fence. Reasonable recommendations made by partners for protection/maintenance of the outhouse will also be considered and coordinated with the historical architect. Action Item 4.9 Maintain/restore historic shell wall terracing. Vegetation is fundamental in erosion control(Glowacki et al. 2000). Native groundcover, such as scorpiontail,rouge plant,and blue porterweed,will be encouraged to grow along the tops and edges of the shell wall terracing to guard against erosion If native groundcover is lacking in an area,seeds will be dispersed. Planting should be avoided unless absolutely necessary. A minimum of six monitoring stations,based on substrate type and proximity to the trail,will be act up along the shell wall. Photo points will be estahl-fished and the height and width of the wall sections will be measured twice a year. The Preserve Manager will coordinate with a qualified archaeologist to develop a shell wall maintenance and restoration plan. Once complete, this maintenance and restoration plan will be incorporated into a revised edition of the Otter Mound Preserve Final Management Plan. The Preserve Manager will follow the recommendations set Conservation Collier Program 38 Packet Page -1107- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve forth in the shell wall maintenance and restoration plan to the reasonable extent that management funds allow. Action Item 4.10 Discourage vandalism. Maintain the preserve and encourage frequent site visits from partners(Marco Island Historical Society, Southwest Florida Archaeological Society, City of Marco, Archaeological and Conservancy, Inc., neighbors). Sites that appear cared for, well maintained, clearly interpreted, and frequently visited,are seldom vandalized(Glowacki et al.2000). GOAL 5: FACILITATE USES OF THE SITE FOR EDUCATIONAL PURPOSES. Action Items 5.1 Maintain interpretive signage and plant signage to educate preserve visitors. One copy of each of the three large interpretive historic signs and nine replacement plexiglass sign covers were purchased with the original large interpretive historic signs in anticipation of damage and wear. The small, white DV resistant signs throughout the preserve may also need to be replaced periodically due to discoloration and wear. Action Item 5.2 Provide Preserve brochures in rainproof box on site. By December 2008. a brochure outlining the native ecosystem and wildlife present at the The box will be inspected monthly by the Preserve Manager and refilled as necessary. Action Item 5.3 Encourage historical presentations and gatherings. Coordinate events with the Marco Island Historical Society and/or The Southwest Florida Archaeological Society. Volunteers from these organizations may provide trail tours for interested parties or for classes of school children upon teacher request. GOAL 6: PROVIDE A PLANFOR SECURITY AND DISASTER PREPAREDNESS Action Item 6.1 •. . • •• Security at the preserve. week: City of Marco Island Police will have agreed to perform routine patrols in the area. Action Item 6.2 Discourage visitation to the park at night. A Lee County Electric Company(LCEC) streetlight was installed at the NE corner of Addison and Leo Courts. A sign designating park hours as dawn to dusk has been installed at the entrance of the preserve. Action Item 6.3 Enforce regulations prohibiting trash and landscape debris dumping in or near the preserve. Conservation Collier Program 39 Packet Page -1108- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve Action Item 6.4 Perform Tree surveys as provided in the attached Tree Management Plan (Appendix 1 1). _. •• . .•b • • . . . .• .. • .. .. • damage • . . .. :� . .. - . _ The preserve manager will maintain Arborist certification or contract this work to a Certified Arborist. Action Item 6.5 Visit preserve within 48 hours after a storm event to assess damage. Staff will take photos of damage and fill out appropriate Collier County Risk Management Department forms. If damage is extensive,the preserve will be closed until public safety hazards are cleared. Action Item 6.6 Promptly clear storm debris from preserve. If necessary,a Collier County emergency debris removal contractor will be contracted as soon as possible after the storm to schedule clean-up. First priority will be the shell walls and the historic outhouse. Damage to the shell walls and outhouse will be documented with photos prior to the start of any clean-up. All debris on top of the shell walls and outhouse will be lifted and carried away by hand, not pulled or dragged. Any large debris on the shell walls or outhouse will be cut into pieces that are small enough to be lifted and carried away by hand or, if the debris cannot be cut into pieces, it will be lifted and carried away by several people working together. Root systems of uprooted trees along the shell walls will not be removed. They will be left in the position in which they fell,and any attached limbs will be cut,lifted,and carried away. Trails will be cleared next. Other downed trees and limbs that do not appear to be a public safety hazard will be cleared at the discretion of the Preserve Manager. As much hurricane debris as possible will be chipped and retained on-site—to be used as mulch for the trail. Debris removal will be carried out in accordance with Goal 4: Protect Archaeological, Historical and Cultural Resources. Funds should he budeeted annually to cover this potential expense. Action Item 6.7 Promptly secure cultural resources after a storm event. Once storm debris has been cleared, damage to the shell walls and outhouse will be documented with photos prior to the start of any repairs. Damage to the shell walls will be initially repaired to the extent possible by the Preserve Manager and staff. Large whelk shells that may have become dislodged will either be gently pushed back into place or gathered and placed near the damaged area. Loosened shell substrate will be gathered and patted back into place. Extensive damage that cannot be repaired by the Preserve Manager and staff will be cordoned off and covered with a tarp until a qualified archaeologist can be contacted. If sections of the outhouse have been blown off, these sections will be gathered and placed inside the outhouse until they can be repaired. All repairs to the shell walls and outhouse will be documented with photos. 4.5 Public Use Facilities Public Access/Parking/Handicap Facilities/Restrooms: There is one public entrance to the preserve, at the north end of the property along Addison Court. A parking area consisting of three parking spaces-one of which is Americans with Disabilities Act(ADA)compliant-exists at the entrance. Both a 375-foot ADA compliant sidewalk trail within the Addison Court right of Conservation Collier Program 40 Packet Page -1109- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve way and a 625-foot mulched trail through the preserve connect to the parking area. Because of the sensitivity and slope of the shell mound, it was not feasible to provide an ADA compliant trail for the entire length of the planned trail. No restrooms exist at the preserve. 4.6 Operational Plan for Otter Mound Preserve 4.6.1 Maintenance Monthly site visits will be made by County staff to inspect/control littering within and around the preserve, monitor exotic plant re-growth, maintain the trail in a safe and aesthetically pleasing way, refill brochure boxes, inspect signs and equipment (bench and trash cans) and review general site security. The Preserve Manager will keep a management log to record observations from the site visit,any contacts made or issues raised. Projects such as exotic removal, debris removal, and plantings will be carried out in accordance with Action Items listed in Section 4.4 Goals and Objectives for 10 year period. 4.6.2 Estimated Annual Costs and Funding Sources Preliminary budget estimates for the Otter Mound Preserve include cost breakdowns associated with resource restoration and management. The funding source identified for the restoration and management activities is the Conservation Collier Program Management Trust Fund. Alternative funding sources, such as mitication and grant funds, will be sought as opportunities arise to supplement existing funding. Table 11 shows the activities planned for the next ten five years and the initial and annual cost estimate of each activity. Private organizations may also provide funding for specific projects. As part of budget reductions made for FY IS. staff will be taking over mach of the exotic maintenance. Some money has been bud<-eeted for contractor assistance if necessary. • Conservation Collier Program 41 Packet Page -1110- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve Table 11: Management Activities Timeline and Cost Activity `14 `15 `16 `17 `18 Total Exotic species $:-0_, 50 5 2.700 $700 53.500 54.050 $16.800 control Cultural resource $ 500 5 500 $ 500 $ 500 $ 500 $ 2.500 Mamnt Debris $ 5011 $ 500 $ 500 $ 500 $ 500 $ 2.500 removal Planting 5 0 $ 100 5 100 5 100 S 100 $ 400 Projects Tree 5',500 52000 52000 52000 $2,000 $10.500 Ni lint Subtotal $9350 55.800 53.800 $6,600 $7.150 532.700 Visitors services/ Recreatio n Parking and 0 0 $350 0 S400 $ $750 sidewalk Equipme nt (bench, 0 0 53,000 0 0 $ 3,000 trash cans) Trail maintena S 0 $ 700 5 0 5 700 1 S 0 $ 1.400 . nce Plant 0 $500 $ tt 0 0 $ 500 Signs Brochure $ 500 5500 . $ 500 5500 5 500 $ 2 500 s Addison Court 5 150 S 150 $ 150 S 150 S 150 $ 750 streetligh t Subtotal $650 $ 1,850 54.000 $ $1.350 $1.050 $8.900 Total $10,000 $7.650 $7,800 57.950 58.200 541.600 Conservation Collier Program 42 Packet Page -1111- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve 4.6.3.

Tortoise burrows, which are useful in determining species'presence, typically have lower, flatter profile than more rounded burrows of armadillos;this reflects differences in cross-sectional shapes of the two animals. Habitat: Typically found in dry upland habitats, including sandhills. scrub,xeric oak hammock, and dry pine flatwoods;also commonly uses disturbed habitats such as pastures,oldfields,and road shoulders. Tortoises excavate deep burrows for refuge from predators.weather,and fire:more than 300 other species of animals have been recorded sharing these burrows. Seasonal Occurrence: Above-ground activity is greatly reduced during cold weather, with tortoises in northern Florida remaining below ground months. Nonetheless,burrows are relatively conspicuous year-round. Florida Distribution: State-wide except absent from the Everglades and Keys_ Range-wide Distribution: Lower Southeastern Coastal Plain extending from southern South Carolina southward through lower Georgia and Florida and westward through southern Alabama.Mississippi_and extreme southeastern Louisiana. Conservation Status: Despite its widespread occurrence throughout Florida, there is considerable concern about the declining abundance of this species. Much of its native habitat has been lost to agriculture. citriculture, forestry, mining, and urban and residential development. Although protected populations occur on many state, federal. and private conservation lands,recent development of a severe respiratory disease threatens even those. Protection and Management: Manage large, undivided tracts of upland habitat to maintain native vegetative conditions; this generally requires periodic prescribed fire beneath trees to reduce brush and favor growth of grasses and forks. Avoid building roads and houses in xeric uplands. Because of risk of introducing tortoises infected with respiratory disease tc uncontaminated populations. tortoises should not he relocated except Conservation Collier Program 62 Packet Page -1131- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve Appendix 5:Otter Mound Preserve June/July 2006 Planting List 85 Trees 5 Strangler Fig 10 Fiddlewood 16 Satinleaf 2 Jamaican Dogwood 6 Wild Tamarind 5 Sea Grape 2 Mastic 7 black bead 4 paradise tree 10 soapberry 7 sweet acacia 8 wild lime 3 gumbo limbo 87 Shrubs 9 White indigoberry 9 Snowberry 2 Curacao bush 11 Coral Bean 10 Firebush 15 Florida privet 9 Spanish stopper 9 Simpson's stopper 3 limber caper 3 Jamaican capers 2 Hogplum 2 red stopper 3 waiter's vibernum 159 ground cover 50 Blue porterweed 13 Corky-stem Passion Vine 50Wild Coffee 21 Rouge plant 25 Scorpiontail Conservation Collier Program 63 Packet Page -1132- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve Appendix 6: 2007 Otter Mound Plant List Plant inventory taken by James N.

DEFINITIONS HABITAT RESTORATION Rehabilitation of degraded or lost habitat. WETLAND RESTORATION 1. Reestablishment,as nearly as practical,of the original(what probably existed prior to degradation)wetland community,including hydrology and native hydrophytic vegetation,and 2. Establishment of a wetland community,including hydrology and native hydrophytic vegetation,different from what probably existed prior to degradation.,but at least partially replacing original habitat functions and values. ASSOCIATED HABITAT RESTORATION I. ReeestabIishment,as nearly as practical,of the original(what existed prior to the degradation)ecological community,including native vegetation,and 2. Establishment of an ecological community,including native vegetation,that is different from what probably existed prior to degradation,but at least partially replacing original habitat functions and values. HABITAT IMPROVEMENT Alteration of existing habitat to increase specific fish and wildlife functions and values. Improvement actions may provide new capabilities,new management options,new structures, revegctation,or other actions to influence one or several functions and values. Improvement differs from restoration in that it does not necessarily seek to reestablish or establish whole ecological communities,and does not necessarily seek to replace original functions and values.

It is a program to acquire,protect,restore and manage environmentally sensitive lands within Collier County. Currently four properties have been acquired through the program and several more properties are being considered for purchase. If received,Partners program funds would be used to restore current as well as future properties. Because the America's Business Park parcel will be the first property to be restored through possible funds from the Partners for Fish and Wildlife Program,it will he the focus of this data sheet. PROJECT LOCATION(State,County,Township,Range,Section,Ecosystem,with map): The Railhead Scrub Preserve property is located east of Old US 41 and south of Railhead Industrial Park in Section 10 Township 48 Range 25 within the northwest corner of Collier County,Florida. The 80.34-acre site contains primarily xeric oak scrub. Palmetto prairie,pine flatwoods,hardwood conifer mixed,cypress-pine-cabbage palm,intermittent pond and freshwater marsh plant communities also exist on the property. See Maps I and 2. Relationship to nearest National Wildlife Refuge,State Management Area,National Forest, Wetland Reserve Program Easement,Other Easement or otherwise protected area: Conservation Collier Program 77 Packet Page -1149- 5/27/2014 16.D.4. 2013 Updated Land Management Plan—Otter Mound Preserve Collier County Barefoot Beach Preserve is located approximately 2.5 miles southwest of the Railhead Scrub Preserve,while Corkscrew Regional Ecosystem Watershed lands are approximately 3.5 miles northeast of the Railhead Scrub Preserve. Both of these protected areas are separated from the preserve by roads and developed property. Two small private conservation areas belonging to North Collier Industrial Park and Railhead Industrial Park are adjacent to the preserve to the west and north respectively. See Map 1. DESCRIPTION AND PURPOSE OF PROJECT: Funds,if received,will be used to remove invasive exotic vegetation from the Railhead Scrub Preserve property. Although the entire parcel will be treated,it is approximated that at least 10 acres of the preserve are infested with exotic vegetation to a significant degree(80%or more exotic plant density). Invasive exotic plant species observed include melaleuca(Melaleuca quinquenervia),Brazilian pepper(Schinns terebinthifolius),downy rosemyrtie(Rhodomyrtus tomentosa),shoebutton ardisia(Ardesia elliptica),earleaf acacia(Acacia auricul(formis)and guava(Psidium gualava). A contractor will be hired to remove invasive exotic plants from the preserve. The contractor will be responsible for the control of any target trees,shrubs,and seedlings and the application of any herbicides within the designated project location. All aspects of the control of listed FLEPPC Category I and H invasive species within the preserve,including any equipment,labor, supply,and herbicide needs,will be the responsibility of the contractor. The contractor will take precautions to avoid harming any native vegetation or wildlife. The vegetation will he cut at or below grade,treated with an appropriate herbicide per label rates and stacked on site,or,if possible,light equipment will be used to remove the debris once the vegetation has been cut and treated. The use of equipment will depend on site-specific conditions. Future monitoring and re-treatment of the invasive exotic plant population within the preserve will be performed by Collier County Staff or qualified contractors. EXPECTED BENEFITS TO FEDERAL TRUST SPECIES (specify and briefly describe for all endangered,threatened,and candidate species,migratory birds,etc.): Gopher tortoises(gopherus poljphemus)inhabit the Railhead Scrub Preserve property. Ninety- six"active",forty"inactive"and eighteen"abandoned"burrows were located during a July 2003 survey by Collier Environmental Consultants,Inc. Although no eastern indigo snakes (Drymarcher corals)have been directly observed on site,it is highly likely that this federally threatened species is present on the property. Removing exotic vegetation and allowing native vegetation to grow in its place will create more habitat for the gopher tortoise and subsequently more habitat for the eastern indigo snake.

Appendix 11. Tree Management Plan Tree Management Plan Otter Mound Preserve, Marco Island, FL Prepared by: Alexandra Sulecki, Certified Arborist FL0561A February 2013 INTRODUCTION The Otter Mound Preserve is a 2.45-acre urban preserve located at 1831 Addison Court within the boundaries of the City of Marco Island in southwestern Collier County, Florida. The preserve lies within the "Indian Hills" section, on the south side of the island. Three parcels totaling 1.77 acres were acquired by Collier County under the Conservation Collier Program in 2004. An additional adjoining .68 acre parcel was acquired in 2007. The property was purchased primarily to protect the existing native Tropical Hardwood Hammock vegetation community. Tropical Hardwood Hammock is becoming rare in Collier County because its aesthetic qualities and location at higher elevations along the coast make it attractive for residential development. Tropical Hardwood Hammock is identified as a priority vegetation community for preservation under the Conservation Collier Ordinance, (Ord. 2002- 63, as amended, Section 10 1.A). The Florida Natural Areas Inventory (FNAI) associates Tropical Hardwood Hammock with a natural community identified as "Shell Mound." which is imperiled statewide (ranking of S2) and globally (ranking of G2), due to its rarity (Guide to the Natural Communities of Florida, 2010). The preserve is managed for conservation, restoration and passive public use. The Preserve's forest has conservation features that draw visitors. Its canopy serves as an important stopover site for a variety of migratory bird species and is home to the Florida tree snail (Liguus.fasciatus), a Florida Fish and Wildlife Conservation Commission (FWC) Species of Special Concern. The Preserve is an archeological and historical site, containing artifacts from Native American Calusa inhabitation between Archaic time to the late 1700"s and from early European settlers of Marco Island and the town of Caxambas. Non-native plant species associated with settler families are also present onsite. The purpose of this Tree Management Plan is twofold: to provide a foundation for documentation, protection and management of the native tree species at Otter Mound Preserve and to identify, prioritize, and eliminate potentially hazardous conditions for visitors and surrounding property owners. Although there is a very low statistical chance of being struck and killed by a falling tree (National Tree Safety Group, United Kingdom, 2011), occasionally unmanaged trees in public park settings have caused injuries which have resulted in legal action. Several large tree potential and actual failures at Otter Mound Preserve during 2012 also prompted the development of a tree management plan. This plan is intended to provide a process to manage tree-related liability at the preserve. Three relevant cases are: 1. Norris v. City of Miami (367 So. 2d 1038, 3rd DCA 1979): Local government's liability to trespassers is limited to "avoiding willful and wanton conduct toward the trespasser" Packet Page -1157- 5/27/2014 16.D.4. and upon discovery of a trespasser, the local government also has the duty to "warn of known dangers not open to ordinary observation." 2. Cusick v. City of Neptune Beach (765 So. 2d 175, 1st DCA 2000): Involved a large tree, in a park, above a park bench. The city had knowledge that the bench posed a hazard to children, who "repeatedly" climbed the tree. Despite receiving a staff warning of the danger, supervisors refused to remove the bench. A child then fell from the tree and was injured when struck the bench. Court held that local governments "have a duty to maintain [their] parks in a condition reasonably safe for public use." Summary judgment in favor of city was reversed, and the case sent back to the lower court (remanded). 3. Silver Palm Properties v. Sullivan (541 So.2d 624, 3rd DCA 1988): Concerned a landowners duty to "regulate the growth of roots from trees growing on his land" where the roots extend beneath a public right of way. In this case, driver and passenger sustained serious injuries when their car hit a series of bumps submerged in rainwater, causing a crash into a nearby tree. Driver and passenger sued adjacent landowner, alleging the roots from their trees (the land was an avocado grove buffered by Australian pines). Court found that, although it may be reasonable to hold a landowner liable for failing to clip back vegetation to avoid foreseeable harm, it is not reasonable to hold a landowner liable for failing to trim roots that, over time, alter the surface of a public right-of-way. Private landowner had no duty. General management goals also include maintaining records of existing tree species, removing invasive exotic tree species and maintaining a healthy diversity in the understory vegetation community appropriate to tropical hardwood hammock. Such maintenance is expected to positively benefit the surrounding residential community by providing a dynamic buffer from urban noise, conserving and protecting soils, protecting property values and conserving and protecting the aesthetic quality that is the heritage of Marco Island. SITE HISTORY This site was occupied by Florida's earliest residents, the Calusa between 750 A.D. and 1,400 A.D. The center of the present-day Otter Mound Preserve appears to have been a main settlement area based on the architecture of the ridges and canals in the direction of the Gulf of Mexico. This group may have been affiliated with the Calusa at Mound Key in Estero. Archeological evidence points to the existence of a large Calusa village near Otter Mound, possibly in present-day Goodland. Numerous artifacts of Calusa occupation have been found at Otter Mound Preserve including shell plummets used to weigh down fishing nets, pot shards dated to 1,200-1,400 A.D. (based on known designs), shell tools and pottery beads. As the site is very rich in artifacts, management activities are directed to disturb the soils as little as possible. Many of the plants currently present at Otter Mound were also present at the time of Calusa occupation including various tree species. These plants served as resources for the Calusa including medicines, dyes, food, tools, and compounds*1. They included: *Source—Collier County Museum and Marco Island Historical Society Packet Page -1158- 5/27/2014 16.D.4. • Jamaica dogwood (Pscidia piscipula)- (fish-fuddle tree) — bark, roots, and leaves were ground into powder and lowered into baskets in the water. Chemical called rotenone found in the tree stunned the fish and caused them to float to the surface to be gathered for food. • Sea grape (Coccoloba uvifera) — edible fruit; Tea made from twigs was held in mouth to help with toothaches and mouth sores. • Stoppers (Eugenia spp.) - edible fruits—Tea from leaves used for diarrhea • Strangler fig (Ficus aurea) —edible fruit; used the inner bark for treating sores and cuts; used fruit for red dye; mixed sap with pigment to make a paint for decorating masks, etc. • Gumbo limbo (Bursera simaruba)—Resin (sap) burned as incense and used as antiseptic and anti-diarrheic. Wood used for carving • Cocoplum (Chr'sobalanus icaco) — edible fruits and seeds (seeds are rich in oil); Tea from leaves used for rheumatism and diarrhea. In historic times, Otter Mound Preserve was part of the village of Caxambas. European involvement with Caxambas is thought to have begun in the 1500's. By 1771, the name Caxambas began to appear on European sailing maps. The name is believed to be a Native American (Arawakan) word for "hole dug in the shore for drinking water, " indicating this area had a freshwater source known and used by visiting ships. By the 1830s, there were plantations along the shore of Caxambas pass and the first modern settler, Tony Roberts (namesake of Roberts Bay) had arrived. From the mid 1800s to the early 1900s, the main occupations of settlers included farming, fishing and clamming. A pineapple farm over 100 acres in size with over 1 million plants existed just north of Otter Mound. In 1901, Jim Barfield bought the entire southeastern tip of Marco Island, including Caxambas and opened a general store. His future wife Tommie Stephens also arrived. In 1905 the Burnham Clam Factory opened and Jim Barfield built the Stephens Hotel including 10-11 small cottages. In 1906, Jim and Tommie married and, shortly thereafter, built the Heights Hotel for winter visitors just north of the Otter Mound Preserve. In 1912, a ferry operation began, and in 1922, nearly all of Caxambas, except for the Otter Mound site, was sold to Barron Collier. In 1923, Collier County was formed. A couple years earlier, 1919, the site had been sold by the Barfields to a Mr. Griner and his wife, who grew cucumbers on the site. In 1923, Griner built a house on the high part of Otter Mound and he and his wife lived there until 1950, when Mr. Griner died and his widow sold the property to Earnest Otter. During that time, Mr. Otter built the shell wall structure that winds 1,700 feet through the property. His goal was to terrace the property for agriculture. He and his wife Gladys lived in the house until 1977. One year later, in 1978, the house burned to the ground. The only structure left from this time period is the outhouse. By 1962, modern development had begun, but this parcel was not developed further. In 2000, the owners of the site, the Gionet family, had an archeological survey done, realized the importance of the site and offered it to the Conservation Collier Program for acquisition as a preserve. Conservation Collier acquired the site in 2004, not because of its historical significance, but because it contained tropical hardwood hammock, a type of vegetation community selected by the conservation Collier Ordinance (2002-63, as amended, Section 10.1.a) as a priority for preservation. Packet Page -1159- 5/27/2014 16.D.4. While it is likely that very little, if any, tropical hardwood hammock remains on the site from Calusa times, many of the native species have re-colonized the site. Old photos show this part of Marco Island relatively cleared by the 1950s. The existing forest appears to be young, possibly 50 to 100 years old. The Griners and Otters added fruit tree species, including mango, avocado, papaya, and guava, which remain as part of the vegetation, as well as landscape and medicinal plants such as copperleaf, royal poinciana, Surinam cherry, Benjamin fig, pencil tree, oyster plant, aloe vera, sansevaria, key lime and yellow elder. Additionally, invasive exotic species had colonized the site, including Brazilian pepper, natal grass, syngonium, air potato, and coral vine. The exotic species listed by the Florida Exotic Pest Plant Council (FLEPPC) in their Category I and II Lists have been removed and management includes chemical maintenance to maintain the site free of exotic regrowth. The forest community also includes some plants protected by the State of Florida Department of Agriculture and Consumer Services, including red stopper (E*), curacao bush (E), naked wood (T*), blackbead (T), hoopvine (E) and giant air plant (E). The full plant list includes scientific names and is part of the Otter Mound Land Management Plan. This Tree Management Plan will be appended to the Otter Mound Land Management Plan.

HABITAT DESCRIPTION Shell Mounds are small hills in coastal locations composed entirely of shells discarded by generations of Native Americas which support an assemblage of plant species that thrive in calcium-rich (calciphilic) environments. Many of the plant species are brought in by migrating birds. Typical Shell Mound tree species present at the Otter Mound Preserve include gumbo limbo (Bursera simaruba), false mastic (Sideroxylon foetidissimum), white stopper (Eugenis foetida), strangler fig (Ficus aurea), wild lime (Zanthoxylem fagara), and blackbead (Pithecellobium guadalupense). Additionally, five tree species (includes 1 palm) found at Otter Mound Preserve are listed as threatened or endangered by the Florida Department of Agriculture and Consumer Services. These include satin leaf (Chrysophyllum oliviforme), red stopper (Eugenia rhombea), Simpson's stopper (Myrcianthes fragrans), blackbead (Pithecellobium guadalupense) and Florida thatch palm (Thrinax radiata).

This is likely that species. KEY STAKEHOLDERS Planning for an effective tree management plan requires support from all stakeholders. The groups listed below have a vital interest in the tree management at Otter Mound Preserve and are to be consulted in the development of this Tree Management Plan. • Conservation Collier Land Acquisition Advisory Committee • City of Marco Island • Adjoining Neighbors ACTION PLAN 1. Inspect and Assess — Perform a visual assessment to consist of systematically viewing each tree from top to bottom and moving 360 degrees around it. Once an approved plan is in place. an initial Tree Survey will be performed with Geographic Information Systems (GIS) ArcMap technology to show the location of all trees over 1 1/2 (one and one half inches) -inches diameter at breast height (DBH) on the Preserve. Each tree will be recorded on a Tree Inventory Data Sheet (Exhibit A): Assessments are to be performed twice annually, after leaf-out in spring (April), after leaf-drop in fall (November) (need citation) and after storm events (Duryea, 2007). The Condition Assessment will be updated if changes are noted. The following items will be Packet Page-1163- 5/27/2014 16.D.4. recorded on data sheets (Albers, et al. 2003) (ISA, 2005) (Gilman, 2011) (Gilman, 2003) (National Tree Safety Group, UK, 2011): • Tree information Tree number—Record the Tree Number Code—Record a two letter Species Code (ie: SG=Simaruba glauca) DBH—Record Diameter at Breast Height • Tree Condition G = Good F = Fair P =Poor D = Dead H = Hazard • Good—Tree has no obvious defects • Fair—One or all of the following conditions indicate a moderate risk of failure: o stem has a single crack and some decay, but less than 25% of the circumference of any stem, branch or root collar is decayed, o Roots within the critical Root Radius are less than or equal to 40% damaged, decayed, severed or dead, o Branches are codominant and unions have included bark, o Branches are larger in diameter than the trunk, o Canker or canker plus decay is present o Branch or branches have a sharp bend or twist; o A large horizontal branch has several vertical branches on it o Dead twigs, tip dieback, branches and small, off-color leaves. o Bark is peeling off the stem o Other trees in the same location have failed. o Tree disease is present o The trunk is malformed o There is little to no flare at the stem base. • Poor—One or more of the following conditions indicate a high risk of failure: o Indicators of advanced decay or canker are found on greater than 40% of the circumference of any stem, branch or root collar, o Stem has advanced decay and the shell thickness has less than 1 inch of sound wood for each 6 inches of stem diameter o Stem has an opening of greater than 30% of the stem circumference and shell thickness is less than 2 inches per 6 inches of stem diameter, o The stem is split in two by a crack, o The stem has multiple cracks and decay o Tree has lightening damage o Large branches are cracked o The tree is leaning with evidence of root lift, soil mounding or soil movement. o Roost within the Critical Root Radius are more than 40% damaged, decayed, severed or dead Packet Page -1164- 5/27/2014 16.D.4. o Girdling roots constrict greater than 40% of the root collar o Weak branch unions are also cracked, cankered or decayed, o There are large epicormic branches on a decaying stem o Canker affects more than 40% of the tree's circumference o Tree is leaning by more than 40 degrees, o Leaning tree has a crack or canker/decay/conch on the lower stem, o Leaning tree has a horizontal crack on the upper side of the lean and/or buckling bark and wood on the lower side. o Bark is peeling off the stem o Dead twigs, tip dieback, branches and small, off-color leaves. o Tree disease is present o Other trees in the same location have failed o The trunk is malformed o There is little to no flair at the stem base • Dead—Tree or top of tree is dead • Hazard Tree— o Dead, Poor or Fair tree that has a "target," in this case the trail or a surrounding residential structure. o Site condition to be considered. Is the tree on a slope or in wet soils? Have nearby trees failed? • Location o Record where the tree is located on a Geographic Information Systems map of the preserve and note any site characteristics that affect tree condition including any existing insect infestations. • Comments- Example= Bark damage, insect damage, Needs additional inspection. 3. Document • Fill out Tree Inventory Data Sheets for biannual inspections. 4. Take Appropriate and Corrective Action, if warranted • After spring leaf—out inspection, create Annual Prioritized Action List to consist of: o Removal Priority 1 List - Highest priority for trees classified as Hazard, or Dead within striking distance of the trail and surrounding residential structures. Schedule removal as soon as possible to consist of severing the trunk at the base and leaving the root system in the ground. Debris to be either hauled away or chipped and spread on the trail, as needed. o Removal Priority 2 List- Trees classified as Poor or Dead that are not within striking distance of the trail and surrounding residential structures. Monitor and take remedial action as warranted for living trees. If dead trees are not posing a hazard to visitors or residents, retain as habitat. o Management Action Priority 1 List — Tree limbs that have defects and have targets. Schedule for pruning. o Management Action Priority 2 List— Tree limbs that have defects but no targets and can be addressed as funds allow or monitored. Packet Page-1165- 5/27/2014 16.D.4. • Trees classified as Fair that are within striking distance of the trail and surrounding residential structures will be inspected on a monthly basis for a change in status. If hazard classification status changes, revise and add to annual Priority Action List for appropriate action. 5. Remove exotic trees After funds are allocated annually for Removal and Management Actions, 50% of remaining tree management funds for that year may be spent to remove exotic trees, with highest priority for FLEPPC Category I exotic trees, next for FLEPPC Category II exotic trees and finally, for removal of introduced non-native trees within 50 feet of the trail and property boundary. Provided that at the discretion of the Conservation Collier Program Manager, some introduced non-native tree species, such as but not limited to mango, avocado, and coconut palm, which provide examples of historical site occupation, or which are not considered invasive, may remain. Fifty (50) % of any unallocated funds must be retained in case of emergency needs and may be rolled over into the following year"s budget. Need for removal of introduced tree species that do not appear on FLEPPC category I and II lists is based on both aesthetics (preferring native trees in the preserve) and introduced species being statistically more likely to fail in hurricane force winds than some native species trees. Some native tree species present at Otter Mound, including gumbo limbo, sea grape and strangler fig, can be expected to survive hurricane force winds better than introduced species (Duryea et al, 2007). Tree removal shall consist of severing the trunk at the base, applying an appropriate herbicide and leaving the root system in the ground. Debris is to be either hauled away or chipped and spread on the trail, as appropriate. 6. Develop a long range restoration plan, if warranted • Assess whether existing trees in open areas have the potential canopy size to develop and maintain a closed canopy and prevent exotic species development. • if gaps are noted that are unlikely to be filled, consider replanting with a tropical hardwood tree species that is present already or was historically present and an important part of the tropical hardwood hammock vegetation community. Locally grown plant material to be preferred. All plantings must be coordinated with Archeology Experts. Budget development: After the spring tree survey, review results and make assessment as to tree care/restoration needs for that year. Develop Annual Budget. A cost benefit analysis can be developed to assist in developing a reasonable tree care budget (USDA Forest Service, Undated). Packet Page -1166- 5/27/2014 16.D.4. REFERENCES Albers, et al. 2003.
