Agenda 12/08/2020 Item #16D 1 (Conservation Collier Logan Woods Preserve update)12/08/2020
EXECUTIVE SUMMARY
Recommendation to approve the Conservation Collier Logan Woods Preserve Final Management
Plan 10-year update under the Conservation Collier Program.
OBJECTIVE: To obtain approval from the Board of County Commissioners (Board) for the 1 0-year
update to the Logan Woods Preserve Final Management Plan.
CONSIDERATIONS: The Conservation Collier Ordinance, No. 2002-63, as amended, Section 14(3),
requires that a Final Management Plan be prepared and updated for each property every five (5) yea rs,
with review and input by the Conservation Collier Land Acquisition Advisory Committee (CCLAAC).
The 5.7 acres Logan Woods Preserve, located at the northwest corner of Pine Ridge Road and Logan
Boulevard, was acquired in 2004. A Final Management Plan was developed and approved by the Board
on June 24, 2008, Agenda Item #16E8. The approved plan has been operational for the Logan Woods
Preserve since that time.
Changes in this plan include updated maps, updated property status information, updates to t he plant or
animal lists, the status of exotic plant and animal infestations, and streamlining of text. Tracked changes
have been made so that Board members can quickly see the proposed changes. Any formatting
irregularities caused by tracked changes will be resolved in the final document.
Each 10-year update requires a public meeting, which was held on November 14, 2019, to allow for
public input on the updated draft plan. CCLAAC reviewed and approved the updated plan on January 13,
2020. Public comments were received and have been taken into consideration by staff. An updated plant
survey was completed in September 2020, subsequent to the public meeting and CCLAAC meeting. The
survey is attached as Appendix 2.
FISCAL IMPACT: Annual costs are estimated at $2,500 per year for the next five (5) years. This is
primarily for invasive exotic plant treatment and trail maintenance. Funds are available within the
Conservation Collier Land Management Fund (174) to accomplish these activities.
GROWTH MANAGEMENT IMPACT: Management of Conservation Collier lands to support
appropriate public access is consistent with and supports Policy 1.1.5 and Objective 1.3 in the Recreation
and Open Space Element of the Collier County Growth Management Plan. There is no specific Growth
Management impact associated with this item.
LEGAL CONSIDERATIONS: The Conservation Collier Ordinance (No. 2002-63, as amended), in
Section 14, provides a legal framework for the development of management plans and the use of
environmentally sensitive lands. This item is approved for form and legality and requires a majority vote
for Board action.-JAB
RECOMMENDATION: To approve the attached proposed 10-year Final Management Plan for Logan
Woods Preserve and directs staff to implement the updated plan.

1.0 Introduction
The Logan Woods Preserve is a natural area within the urban boundary of Collier County, Florida.
The property is made up of two parcels, which total 7.49 acres in size, out of which the County
Transportation Department has partnered with Conservation Collier to buy 1.8 acres of road
easements, leaving a total of 5.69 acres for conservation. Extensive exotic removal was completed
on the property in 2007, and the remaining vegetative community consists of Pine, Cypress and
Cabbage palm.
A site assessment to determine compliance with Conservation Collier’s initial screening criteria
was conducted on August 21, 2003, and the Conservation Collier Program purchased the property
on October 14, 2005. Previously known as the “McIntosh Trust” property, for the previous
owners, it was renamed Logan Woods Preserve in November 2006. The County holds fee simple
title to the Logan Woods Preserve. The Conservation Collier program manages these lands under
authority granted by the Conservation Collier Ordinance 2002-63 as amended (available from
www.municode.com). Initial acquisition activities are summarized in Table 1.
According to the Southern Biomes Report dated April 14, 2000, the preserve consists of 1.5 acres
of wetland habitats and approximately 4.4 acres of upland habitat. To keep the acreage mentioned
in this plan consistent, the total preserve acreage will be referred to at 5.69 acres for the remainder
of this plan. Conservation, restoration and natural resource-based recreation as defined by Sec. 54-
275 (Ord. No. 02-63, § 5, 12-3-02) are the designated uses of this property. Management activities
allowed include those necessary to preserve, restore, secure and maintain this environmentally
sensitive land for the benefit of present and future generations. Public use of the site must be
consistent with these management goals.

All Land Management Plans must be approved by the Collier County Board of County
Commissioners (BCC). When approved, this plan will replace the existing Final Management
Plan.
1.1 Conservation Collier: Land Acquisition Program and Management Authority
The Conservation Collier program was originally approved by County voters in November 2002
and subsequently confirmed in the November 2006 ballot referendum. Both voter-approved
referendums enable the program to acquire environmentally sensitive conservation lands within
Collier County, Florida. Properties must support at least two of the following criteria 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
Conservation Collier Land Acquisition Advisory Committee (CCLAAC) 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.
Lands acquired with Conservation Collier funds are titled to “COLLIER COUNTY, a political
subdivision of the State of Florida, by and through its Conservation Collier program.” The Board
of County Commissioners of Collier County established the Conservation Collier program to
implement the program and to manage acquired lands. As such, Conservation Collier holds
management authority for the Logan Woods Preserve.
1.2 Purpose and Scope of Plan
The purpose of this plan is to provide management direction for Logan Woods Preserve by
identifying the goals and objectives necessary to eliminate or minimize any threats to the resources
and integrity of the preserve. This text is a working document that establishes the foundation of
the ten-year plan by identifying the appropriate management techniques necessary to preserve
and/or restore the resource.
This plan will balance resource restoration and protection with natural resource-based recreational
and educational uses while looking at restoration needs, listed species protection and maintenance
of the site free of invasive, exotic plant and animal species. This plan is divided into sections that
incorporate an introduction, descriptions of the natural and cultural resources, projected uses of
the property, management issues, and goals and objectives.
1.3 Location of the Logan Woods Preserve
Logan Woods Preserve is located within the urban boundary of Collier County, Florida and
consists of two (2) parcels located at the northwest corner of the intersection of Pine Ridge Road
and Logan Blvd. It is located one mile east of Interstate-75 in Section 16, Township 49, and Range
26. It is in an Estates zoned area of the County.

1.4 Regional Significance of the Logan Woods Preserve
To date, approximately 68% (more than 877,000 acres) of Collier County is protected within
conservation areas (Figure 2) and managed by private organizations and by local, state and federal
agencies. Collier County’s Conservation Collier Program manages the 5.69-acre Logan Woods
Preserve. Although this preserve is relatively small, it provides green space at a very busy
intersection and serves as a neighborhood preserve. Specific information on the uplands found on
the Logan Woods Preserve may be found in section 2.3 (Natural Plant Communities) of this
document. A general view of the Logan Woods Preserve is provided in Figure 3.

2.0 Natural Resources
2.1 Physiography
Logan Woods Preserve lies within the Floridian section of the Coastal Plain. The Coastal Plain
extends from New Jersey to Texas and was formed mainly from sedimentary rocks deposited in
marine environments (USGS 2004).
2.1.1 Topography and Geomorphology
The topography of the area is relatively level with a land surface elevation of approximately 13
feet (4 meters) above mean sea level. The property lies within the USGS Topographic Quadrangle
Map for Bell Meade NW Florida. Surface water percolates directly into the ground or it collects
in natural depressions and man- made ponds on adjacent properties. Surface water appears to be
controlled by topography and drainage. Ground water flow in the surficial aquifer system generally
mirrors surface topography and would appear to be flowing to the west/southwest in this general
area, however surrounding water bodies may have an influence on the ground flow direction
(ASGgeosciences 2005). Collier County lies within the southern or Distal Physiographic Zone.
The portions of Collier County where the Logan Woods Preserve is located is in the Southwestern
14
Slope. It is between the Gulf of Mexico and the western edges of the Immokalee Rise and the Big
Cypress Spur (Liudahl et al. 1990).
2.1.2 Soils
According to Liudahl et al. (1990), soils mapped at the Logan Woods Preserve are entirely Pineda
Fine Sand, Limestone Substratum (See Figure 5). This hydric, nearly level, poorly drained soil is
typically found in sloughs and drainage ways. Limestone bedrock is located at a depth of about 55
inches. Natural vegetation includes slash pine, cypress, wax myrtle, and grasses. The permeability
of this soil type is slow and the available water capacity is low. Areas underlain with Pineda Fine
Sand, Limestone Substratum can be flooded during periods of high rainfall, but typically, the water
table is within a depth of 12 inches for 3 to 6 months of the year. The water table can recede to a
depth of more than 40 inches during dry times.
2.1.3 Hydrology/Water Management
The hydrology of the site has been altered significantly since the mid 1980’s when Pine Ridge
Road was constructed. The property was cut off from natural water flows with the construction of
the surrounding roads (i.e., Sycamore Drive to the north, Logan Blvd. to the east and Pine.
Ridge Road to the south). There is a drainage ditch to the south of the property that captures the
rainwater runoff from Pine Ridge Road and the property; this water flows west into the South
Florida Water Management maintained-1-75 canal. There is also an old minor swale/berm that
exists on the western side of the property and runs north and south. Water tends to pool up on the
western side of the swale during rainy season.
Groundwater levels have gone down during the recent decades due to drainage on a regional scale
and water management for development purposes. This trend may be very difficult to control and
will continue to reduce the extent of the preserve that floods during the summer months and reduce
the period of time the preserve wetlands are flooded during the year.

2.2Climate
The Logan Woods Preserve is located in an area of Florida where humid subtropical and tropical
savanna climatic patterns overlap, with temperatures moderated by winds from the Gulf of Mexico
and the Atlantic Ocean. Sharply delineated wet and dry seasons and average monthly temperatures
greater than 64º Fahrenheit characterize a tropical savanna climate. Monthly rainfalls may exceed
ten inches during the wet season. On the other hand, humid subtropical climates typically show
less extreme rainfall fluctuations between wet and dry seasons and average monthly temperatures
is less than 64º Fahrenheit in some months (URS IRC 2006).
The average annual temperature for Collier County is approximately 75º 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 from May to October. Thunderstorms
are frequent during the wet season, occurring every two out of three days between June and
September. Rainfall records for the area indicate that there is not significant variation in the annual
rainfall throughout much of the county; however, large variations often occur during a single year.
The hurricane season extends from June through November with peak activity occurring in
September and October when ocean temperatures are highest (URS IRC 2006).
2.3 Natural Plant Communities
A plant community refers to the suite of plant species that form the natural vegetation of any place.
In addition to anthropogenic influences, the combination of factors such as geology, topography,
hydrology, underlying soils and climate determine the types of plants found in an area. These
plants, in turn determine the animal species that may be found in an area.
The Florida Land Use, Land Cover Classification System (FLUCCS) GIS layer provided by South
Florida Water Management District notes only one plant community on the preserve: Upland
Hardwood Forests-Melaleuca Infested (FLUCCS code 424; Figure 6). Additionally, the whole
site is mapped as having hydric soils (Liudahl et al. 1990). In April 2000, Southern Biomes
conducted a site visit and determined that the Logan Woods Preserve consists of approximately
4.4 acres of upland habitat and approximately 1.5 acres of wetland habitat. When Conservation
Collier acquired the parcel, approximately 80-90% of the property was infested with melaleuca
(Melaleuca quinquinervia). Florida Natural Areas Inventory (FNAI) staff visited this site in 2006;
they recorded the amount of exotic cover present and noted the location(s) via a Global Positioning
System (GPS) device (Figure 7). Subsequently, melaleuca and other invasive, exotic plant species
were removed from the preserve in May 2007. Since that time, with the preserve maintained free
of exotic plants, numerous pine seedlings have begun to grow, among other native understory
plants, effectively providing some restoration to the historic and natural forest community.
However, the large amount of pine seedlings growing reflected the hydrologic isolation of the
parcel and if they were permitted to grow, would change the characteristics of the plant
community. Therefore, after research and discussion with Florida Division of Forestry personnel,
and reviewing program goals for the property, it was determined to remove approximately 2/3 of
the seedlings. In June 2013, approximately 1,500 pine seedlings were removed from 3 sections
of the preserve, with one section left undisturbed, leaving approximately 500 pine seedlings for
regeneration purposes.

2.3.1 Uplands: Upland Hardwood Forests
As mentioned in the previous section, Logan Woods Preserve was primarily dominated by
invasive, exotic melaleuca trees at the time of acquisition; the native plant community mapped on
the preserve is an upland hardwood forest – melaleuca infested. As such, the following section
will describe the native species commonly found in this community; section 3.4 and 4.4 of this
management plan (Goals for the 10-year period 2008-2018) will discuss methodologies to
control/eradicate melaleuca and other problematic, floristic species on the preserve.
Upland hardwood forests in south Florida are also known as upland mixed forests, prairie
hammocks, xeric hammocks, hydric hammocks (FNAI & FDNR 1990) and mesic temperate
hammocks (USFWS 1999). This plant community is often characterized by hardwood species
such as live oak (Quercus virginiana) and cabbage palms (Sabal palmetto) that form a closed
canopy. Other trees found in these communities include temperate species such as water oak
(Quercus nigra), laurel oak (Q. laurifolia), hackberry (Celtis laevigata) and red maple (Acer
rubrum). The high amounts of shade and leaf litter provided by the canopy keeps the soils
relatively moist. Consequently, the mid-stories and groundcovers are species-poor. The frequency
of epiphytes is usually higher than other herbaceous plants (USFWS 1999).
The closed canopy and abundant hardwood mast provided by this plant community attracts a
number of wildlife species seeking food, cover, roosting, and nesting sites. Additionally, these
areas are ideal stopover areas for migratory passerines. Since these communities occur on
relatively well-drained sites, they are also attractive for human habitation and recreational uses.
These anthropogenic uses have increased the number of invasive plant and animal species in these
areas and have resulted in degraded hardwood forests throughout the state (USFWS 1999).
The Logan Woods Preserve is mapped as an upland hardwood forest – melaleuca infested,
however, this is inconsistent with what is currently present on site. Conservation Collier Staff
have consistently observed a cypress – pine - cabbage Palm-melaleuca infested community during
site visits. Therefore, a description of the latter plant community is provided in the following
section.
2.3.2 Uplands: Cypress – Pine – Cabbage Palm
As the name suggests, the cypress- pine-cabbage palm community is composed of a mixture of
Cypress, Pine and Cabbage Palm Canopy trees – none of which are dominate. This community is
often the transition zone between moist upland and hydric sites. As such, some of the flora and
fauna associated with moist upland and hydric sites are found in this type of community.
In 2003, Conservation Collier Staff noted that the existing native canopy consists of cypress
(Taxodium distichum) and slash pine (Pinus elliottii var. densa). Native, midstory species include
cabbage palm (Sabal Palmetto), myrsine (Myrsine floridana), willow (Salix sp.), and buckthorn
(Bumelia sp.). Native groundcover include swamp fern (Blechnum serulatum), giant hatpins
(Eriocaulaceae sp.), yellow-eyed grass (Xyris caroliniana), various wetland grasses and forbs.
20
2.4 Native Plant and Animal Species
Indigenous or native species are those whose natural ranges included Florida at the time of
European contact (circa 1500 AD). Additionally, species that have naturally expanded or changed
their ranges to include Florida are considered native. Florida represents a relatively broad
geographic range; some species, which may be native to the northern part of the state, may not be
native to the southern part and vice versa. Similarly, species exist that are native to coastal areas
but not to inland areas and vice versa. Therefore, for the purposes of this management plan, species
deemed native are those that are not only indigenous to Florida, but also to Collier County. These
species will be discussed in the following sections.
2.4.1 Plant Species
At creation of the preserve, Conservation Collier staff identified 60 plant species at the preserve
(Appendix 2). Of these 60 species, 48 (80%) were native to the site and 12 (20%) were invasive
exotic. The Florida Exotic Pest Plant Council listed all twelve exotic species. After 8 14 years of
management, less than 5% of exotic species remain.
2.4.2 Animal Species
Little is recorded for actual occurrences of animals at the preserve. Occurrences of fauna at the
preserve are based on direct visual and aural observations by staff during site visits of animals or
evidence of activity such as spoor, scat, or burrows, and from the site information available in
documents such as
• the site’s initial criteria screening report;
• the property’s interim and current management plan;
• anecdotal information from persons with knowledge of the site.
Mammal species known to occur or individuals and/or evidence of activity directly observed
within the preserve include: Virginia opossum (Didelphis virginiana), nine-banded armadillo
(Dasypus novemcinctus), marsh rabbit (Sylvilagus palustris), and raccoon (Procyon lotor).
Reptile and amphibian species observed at the preserve include: the brown anole (Anolis sagrei),
and the southern black racer (Coluber constrictor priapus), Southern leopard frog (Lithobates
sphenocephalus), and the exotic brown basilisk (Basiliscus vittatus). Invertebrates observed
include the following butterfly species: the gulf fritillary (Agraulis vanillae), the zebra longwing
(Heliconius charitonius), white peacock butterfly (Anartia jatrophae) and the cloudless sulphur
(Phoebis sennae).
Staff has observed several bird species to be perching, foraging, or exhibiting nesting behavior at
the preserve (Table 3).
The Florida Breeding Bird Atlas lists 49 bird species that have been recorded as confirmed,
probable, or possible breeding in the vicinity of the site (in the Belle Meade NW USGS
quadrangle) (Table 4). The Breeding Bird Atlas documents breeding distributions of all bird
species in Florida between 1986 and 1991. Some of these species may breed at the Logan Woods
Preserve.

2.5 Listed Species
Indigenous species that have been recognized to be vulnerable to extinction to varying degrees are
called listed species. The Florida Fish and Wildlife Conservation Commission and the Florida
Department of Agriculture and Consumer Services produce official lists of rare and endangered
species at the state level; the United States Fish and Wildlife Service and the National Marine
Fisheries Service produce official lists of rare and endangered at the federal level. FNAI produces
a list of rare and endangered species, and maintains a database of occurrences of these species in
Florida. The Institute for Regional Conservation (IRC) also ranks native plant species by
conservation status in the 10-county area of South Florida. The following subsections (2.5.1 and
2.5.2) discuss the listed, rare and protected plant and animal species found within and close to the
Logan Woods Preserve.

2.5.1 Listed Plant Species
There are four (4) listed plant species at Logan Woods Preserve that are listed by the Florida
Department of Agriculture and Consumer Services (FDACS), three (3) are Endangered and one
(1) is Threatened (Table 5). A brief description of these species and their status is included in the
following paragraphs.
E: Endangered, T: Threatened,
The Cardinal Airplant, also known as the Common Wild Pine or Stiff-leaved Wild Pine
(Tillandsia fasciculata), is an epiphytic bromeliad
recognized by many common names and is listed as an
endangered plant by the State of Florida. Wunderlin and
Hansen reported this species in 24 counties throughout
Florida as of 2004 (Wunderlin & Hansen 2004). Like
most of the other bromeliads in Florida, this species is
often referred to as a “tank” bromeliad because the leaf
axils and central stems form a “tank” or reservoir at the
base of the plant. These reservoirs capture and hold
water, dead and decaying plant matter (leaves, seeds
twigs, etc.), and dead and drowning
non-aquatic insects; these trapped items provide nutrients
for the plant (Larson et al. 2006).

The Reflexed wild pine (Tillandsia balbisiana) is also a common epiphyte in
South Florida. This species prefers moist forests and swamps and is state listed
as threatened.
The Fuzzywuzzy airplant (Tillandsia pruinosa) is listed as an endangered
plant by the State of Florida. Collier County is the only county within the state
where this species has been confirmed to exist (Wunderlin & Hansen 2004).
The epiphyte is less than 6 inches tall and is usually solitary. This air plant is
generally found in isolated habitats.
Even though the three Tillandsia species listed above are fairly
commoncommon in the State, they are listed due to illegal collecting and the
destruction of the habitats in which they are found. Infestation by the
introduced Mexican bromeliad weevil (Metamasius callizona) has been
implicated in the decline of many epiphytic air plant populations around the state. Currently there
are no control measures in place however, close research and monitoring is taking place.
FNAI maintains a database of occurrences of rare, threatened, and endangered species in Florida.
These element occurrence data are built into biodiversity matrices. Each matrix encompasses one
(1) square mile and includes all species and natural communities tracked by FNAI, including all
federal listed species. The Logan Woods Preserve site is located within FNAI’s Biodiversity
Matrix Unit 40541. Appendix 3 provides the official FNAI Managed Area Tracking Record and
Element Occurrence Summary as well as the Biodiversity Matrix Report. Global and state
rankings are provided for each species as well as their federal and state status. There were no plant
species listed as “likely” to occur on site (rare species likely to occur in this matrix based on
suitable habitat and/or known occurrences in the vicinity). None of the plant species reported by
FNAI as “potential” listed species have been detected within the Preserve. Six (6) plant species
were reported within this Biodiversity Matrix as “potential” occurrences (site lies within the known
or predicted range of species) including the nodding pinweed (Lechea cernua) and the celestial
lily (Nemastylis floridana).
2.5.2 Listed Animal Species
No listed wildlife species have been observed onsite or immediately adjacent to the site. However,
within FNAI’s Biodiversity Matrix 40541, in which the preserve lies, the wood stork (Mycteria
americana) was recorded as “likely” to occur (rare species likely to occur in this matrix based on
suitable habitat and/or known occurrences in the vicinity). Eleven (11) species were reported
within FNAI’s Biodiversity Matrix as potential occurrences (site lies within the known or predicted
range of species) however, none of these species have been detected on site. These include the
Eastern indigo snake (Drymarchon couperi), the gopher frog (Rana capito), the gopher tortoise
(Gopherus polyphemus), the red-cockaded woodpecker (Picoides borealis), and the Florida
bonneted bat (Eumpos floridanus) (See Appendix 3).

2.6 Invasive Non-native and Problem Species
In an ecological context, an invasive species is one that is aggressive in growth and expansion of
range and tends dominate others; its establishment and dominance can cause widespread harm to
an ecological system by altering the species composition, susceptibility to fire and hydrology of
an area. Non-indigenous (a.k.a. non-native species, exotic species) species are those that have
been purposefully or accidentally introduced to an area outside their normal range. The
characteristics of some of these species (high rate of growth/reproduction, no natural predators,
easily dispersed, able to out-compete native species) make them invasive. While some native
species may become invasive, the establishment and dominance of non-native species is of
particular concern.
The Florida Exotic Pest Plant Council (FLEPPC) maintains a list of exotic plants that have been
documented to (1) have adverse effects on Florida’s biodiversity and plant communities, (2) cause
habitat losses due to infestations and (3) impact endangered species via habitat loss and alteration.
Although Florida does not have an official exotic, invasive animal species list, at least 400 exotic
fish and wildlife animal species have been reported in Florida, and approximately 125 species are
established. While only two three invasive, non-indigenous animal species have been documented
within the Preserve, other species also have a potential to occur in Logan Woods and will be
discussed in section 2.6.2.
2.6.1 Invasive and Problem Plant Species
To date, twelve (12) introduced plant species have been found at the Logan Woods Preserve
accounting for 23% of the plant species recorded there. Eight (9) of the exotic, invasive species
are considered Category I species by FLEPPC and two (3) are listed as Category II (Table 6).
FLEPPC defines Category I plants as those that alter native plant communities by displacing native
species, change community structures or ecological functions, or hybridize with natives. Category
II plants have increased in abundance or frequency but have not yet altered Florida plant
communities to the extent shown by Category I species. These definitions do not rely on the
economic severity or geographic range of the problem, but on the documented ecological damage
caused (FLEPPC 2007).
The most problematic exotic, invasive plant species at Logan Woods Preserve was melaleuca. Old
world climbing fern (Lygodium microphyllum) was also found to be spreading throughout southern
portion of the preserve. Other invasive species listed in table 6 were found throughout the preserve.
In May 2007, all exotic, invasive species received initial treatment. The majority of the removal
project was funded by the DEP Bureau of Invasive Plant Management. Since then, maintenance
continues to ensure that the site remains free of exotics. The details of the project will be
summarized in Section 3.4 and 4.4, of this document.
25
Under certain conditions, especially following soil disturbance or drainage, some native plant
species can become invasive. Currently, there are no native plant species at Logan Woods Preserve
that represent a management problem. However, close monitoring will be done each year to ensure
that cabbage palm trees (Sabal palmetto) and muscadine grape vine (Vitis rotundifolia) do not start
to become problematic. If this occurs, steps will be taken to contain these invasive species such
as cutting back or treating vines and reducing the numbers of the cabbage palm seedlings.
2.6.2 Invasive and Problem Animal Species
Two Three (23) non-indigenous, invasive animal species have been documented on the Preserve:
the red imported fire ant (Solenopsis invicta) and the brown anole (Anolis sagrei), and the brown
basilisk (Basiliscus vittatus). Based on the natural communities found within the preserve, its
proximity to residential areas and its general geographic location, several more species (native and
non-native) have the potential to impact the Logan Woods
Preserve to varying degrees. Brief descriptions of documented
and undocumented but potentially problematic species are
provided in the following paragraphs.
Red imported fire ant (Solenopsis invicta): documented within
the Logan Woods Preserve
These social insects were introduced into the U.S. from Brazil into
either Mobile, Alabama or Pensacola, Florida between 1933 and
1945 (Collins & Scheffrahn 2005) and have been detected in the
Logan Woods Preserve. Red imported fire ants (RIFA) have been
documented to cause harm to humans and wildlife as well as
economic harm (Stimac & Alves 1994; Collins & Scheffrahn 2005; Willcox & Giuliano, 2006).
RIFAs are omnivorous, but they prefer insects as their primary food source (Willcox & Guiliano
2006). RIFAs have a number of impacts on wildlife. They have eliminated many areas of native

ant populations through competition and predation and have eradicated food sources utilized by
some wildlife species. Ground-nesting wildlife is especially susceptible to RIFAs. Within the
Logan Woods Preserve, RIFAs have the potential to affect ground-nesting birds; small mammals;
reptiles such as gopher tortoise, native lizard and snake species, and native invertebrates (Willcox
& Giuliano 2006). Additionally, members of the public that come into contact with RIFAs may
be harmed if stung. Many people have anaphylactic reactions to the toxins released from RIFA
stings.
Brown Anole (Anolis sagrei): documented within the Logan
Woods Preserve
Also known as the Cuban anole, the brown anole is native to Cuba,
the Bahamas, and neighboring islands (Schwartz & Henderson
1991). Like other anoles from the islands, this species is a small,
tropical, diurnal, arboreal, territorial, and insectivorous lizard
(Campbell 2001). The brown anole was first documented in the
Florida Keys in the late 1800s (Lee 1985) and has since spread
throughout Florida, into Georgia and into two other southeastern
states (Campbell 1996). The brown
anole is a habitat generalist and
generally prefers the fairly open areas
of disturbed sites; in Florida; it feeds on
a wide variety of insects, amphipods, and isopods. Brown anoles also
prey on other small vertebrates including the hatchlings of the native
green anole (Anolis carolinensiis; Campbell 2000). Campbell (2000)
showed that, in the absence of the exotic brown anoles, native green
anoles occupy perches from ground to the canopy of vegetation.
However, in the presence of the exotic anole, native anoles move
higher in trees, occupying only the trunk and crown of trees. Dietary
overlap is high between both species, but the overall affects of the
brown anole on the green anole are still undetermined.
Cuban tree frog (Osteopilus septentrionalis): undocumented
within the Logan Woods Preserve
Like the Cuban anole, the Cuban tree frog is native to Cuba, the
Bahamas, and neighboring islands. The first Cuban tree frogs
probably arrived in the Florida Keys as stowaways in shipping crates
originating from the Caribbean in the 1920’s. Today, they have
established breeding populations as far north as Cedar Key on
Florida's Gulf Coast, Jacksonville on the Atlantic Coast, and
Gainesville in north-central Florida. These hylids are the largest tree
frog found in Florida and because of their ability to invade natural
areas and prey on native invertebrates and small vertebrates
(including native tree frogs) they are considered an invasive

parotid
species. Cuban tree frogs thrive in residential and natural areas such as pine forests, hardwood
hammocks, and swamps. In residential settings, they are most commonly found on and around
homes and buildings, and in gardens and landscape plants. They are known to get into transformer
boxes and electrical switches causing power outages (Johnson 2007). Due to the natural
communities that are found within the Logan Woods Preserve and its proximity to residential
areas, this species has the potential of occurring in the preserve.
Giant Marine Toad or Cane Toad (Bufo marinus): undocumented within the Preserve
The cane toad is a tropical species native to the Amazon basin in South America, and its range
extends through Central America to extreme southern Texas along the Rio Grande River. They
are used as a control agent for insects that damage sugarcane and consequently, are one of the most
introduced amphibian species in the world. In 1936, an attempt was made to introduce this species
into Palm Beach County, FL. This attempt to introduce the
exotic species failed as did two subsequent efforts. Ironically,
in 1955, an accidental release by an importer at the Miami
International Airport in Miami-Dade County, FL proved
successful. They have since been deemed an invasive species
in Florida and are currently found in urban areas of south and
central Florida, and are rapidly expanding northward (Brandt
& Mazziotti 2005). Many of this species’ characteristics
enable it to do well in south Florida. Beetles, bees, ants,
winged termites, crickets and bugs are a large part of the diet
of the adult marine toad. Additionally, they will consume
arthropods, mollusks, small vertebrates, plant matter, pet food,
carrion, household scraps, marine snails, smaller toads and native frogs, small snakes, and even
small mammals. Marine toads are prolific breeders and females can lay tens of thousands of eggs
in a single breeding season. They prefer forested areas with semi permanent water nearby
(Churchill 2003). Due to the natural communities that are found within the Logan Woods Preserve
and its proximity to residential areas, this species has the potential of occurring within the preserve.
Adjoining residents of the preserve should be encouraged to keep pet food and water containers
indoors or empty at night.
Feral domestic cat (Felis catus): undocumented within the Logan Woods Preserve
Domestic cats originated from an ancestral wild species, the European and African wildcat (Felis
silvestris). Humans facilitated the global distribution of cats due to their highly efficient predatory
skills. Egyptians took cats with them on shipping vessels to keep rodent populations down, and
they likely introduced domestic cats to Europe. Subsequently the expansion of the Roman Empire
and European missionary missions facilitated the spread of domestic cats into Asia and beyond
(Masterson 2007). Today, the impact of feral cats on wildlife is difficult to quantify; however,
literature (FFWCC 2001; Karim 2007; Masterson 2007) strongly indicates that they are a
significant factor in the mortality of small mammals, birds (including migratory birds), reptiles,
and amphibians in Florida. Because free-ranging cats often receive food from
Bufo marinus, an invasive, exotic amphibian
that has the potential to occur at theLogan Woods Preserve Photo courtesy of the USGS
28
humans, they may reach abnormally high numbers. An increase in the population of feral cats
may lead to increased predation rates on native wildlife. While no cats have yet been observed on
the Logan Woods Preserve, there exists a high probability of their future presence on the preserve
due to the proximity of Logan Woods to human residential areas. Adjoining residents of the
preserve should be encouraged to keep their cats indoors and staff should monitor the preserve for
the presence of feral cats.
3.0 Previous and Current Use of the Preserve; Adjacent Land Uses
3.1 Previous and Current Use
Aerial photography taken in 1940, 1962, 1985, 1994 and recent physical visits to the site show that
development has never occurred on the site. These aerial photographs are available in the public
records at the Collier County Property Appraisers Office, online from the State University System
of Florida website, and at the USDA Natural Resources Conservation Service Office located in
Immokalee, FL. A 1962 aerial is shown in Figure 8 to display what the area looked like prior to
major development. A Phase I Environmental Site Assessment was conducted on the site by
ASCgeosciences dated August 2005, before the property was purchased by the Conservation
Collier Program. This report, available as County public record, both confirmed the above
comments and revealed that no evidence of recognized adverse environmental conditions exist on
the property.
In 2007, prior to initial exotic removal, County staff discovered (15) 5-gallon barrels of used motor
oil and other miscellaneous debris on the property, just over the northern property line. The
Pollution Control Department was notified and an investigation took place. Since then the barrels
were removed, all contaminated soil was removed by County staff and the oil and debris was
disposed of properly by the adjacent land owners at their expense.
3.2 Cultural, Historical and Archeological Resource Protection
The Logan Woods Preserve is not within an area of historical and archaeological probability, and
no historical or archaeological sites appear to be present on the property. The County will notify
the Division of Historical Resources immediately if evidence is found to suggest any
archaeological or historic resources are discovered. If such resources are identified on-site, staff
shall cordon off the area, and a professional survey and assessment shall be instituted. The
archaeologist shall prepare a report outlining results of the assessments and issue recommendations
to County staff about management of any sites discovered, per provisions of the Land
Development Code Section 2.2.25. This report shall be sent to the Division of Historical
Resources. The County shall cooperate fully with direction from the Division of Historical
Resources on the protection and management of archaeological and historical resources. The
management of these resources will comply with the provisions of Chapter 267, Florida Statutes,
specifically Sections 267.061 2 (a) and (b).

3.3 Current Adjacent Land Uses
The Logan Woods Preserve property is currently surrounded by development. To the north is a
single family home located on an Estates zoned lot. The western half of this private parcel is not
developed; Sycamore Drive is located to the north of this private property.
To the west of the Logan Woods Preserve is a gated community called the Vineyards. Pine Ridge
Road is immediately adjacent to the south of the preserve and Logan Blvd. is immediately adjacent
to the east. Across these main roads are additional estates zoned properties of which some remain
undeveloped (Figure 9).

3.4 Major Accomplishments During Previous Years
Since the acquisition of the Logan Woods Preserve in August 2005, key accomplishments have
been achieved (Table 7). The program received a grant award from the Department of
Environmental Protection’s (DEP) Bureau of Invasive Plant Management (BIPM) for the removal
of the invasive, exotics on the property. Since the melaleuca was so dense, DEP agreed the most
efficient way to eradicate the species was by mechanical means. Staff utilized a State approved
contractor to mobilize a piece of machinery, called a Brontosaurus. This large, tracked excavator
with a long arm attached to a mowing head, mowed the dense stands of melaleuca down to the
ground resulting in fine pieces of mulch. In the ecologically sensitive areas that line Logan Woods
Blvd. and Pine Ridge Road, an additional contractor was used by the County to remove exotics by
hand. Care was taken to preserve as much of the native vegetation as possible. DEP paid a total
of $38,000 for the mechanical removal portion and the County paid $9,200 for the hand removal.
All of the melaleuca trees were successfully mowed and the mulch was spread out throughout the
property (See Figure 3). Herbicide re-treatments have occurred every four months since the initial
event to treat any new seedling growth and will continue every six months until all exotic plants
are in maintenance condition. As of 2013, the property is in maintenance condition regarding
exotics. Hand pulling will be used on specific exotic species to avoid over use of herbicides. Very
few exotic seedlings have been growing back; this may be a result of the mulch layer left, however,
31
many native plants have recovered in great numbers such as slash pine, swamp ferns, cabbage
palms, and beautyberry.
Conservation Collier Staff also coordinated with the USDA TAME Melaleuca Program (The
Areawide Management and Evaluation of Melaleuca through the United States Department of
Agriculture and the University of Florida Extension Service) to fund the exotic removal on the
undeveloped portion of the adjacent private lot, which was also heavily infested with melaleuca
(Figure 10). Staff received permission from the neighboring property owner to conduct the project
on his property. The project took place simultaneously with the removal on the adjoining Logan
Woods Preserve. County staff received bids from County and State approved contractors, obtained
agency permits and facilitated the project on behalf of TAME. The contractors removed a portion
of melaleuca by mechanical means, killed a portion in place and removed the remainder by hand.
Two different herbicide treatment methods were used for public demonstration including cut
stump treatment and frill and girdle treatment. Some debris was completely removed from the
site, some was mulched and left around the perimeter and the remainder was stacked in log cabin
style piles on site for demonstration. A public event was held on August 25, 2007 to educate the
neighbors and other members of the public about the need for exotic removal/ eradication and
about the different methods that can be used. In addition to providing an educational demonstration
of melaleuca removal on the adjoining privately owned parcel, the project eliminated the
melaleuca seed source from the adjacent property. TAME funded a total of $11,570 and the
County paid $275 for the TAME event permits. All of the melaleuca on the private lot were
successfully eradicated. One follow-up treatment was conducted by a contractor following the
initial treatment at no cost.

In January 2008, a fence was installed along the northern property line. A six-foot high, wooden
privacy fence was built along the eastern half of the northern boundary and a field fence was
installed along the western half. This privacy fence provided a definite boundary between the
preserve and the developed portion of the neighboring property. This will cut down on potential
encroachments and dumping, and will provide the preserve guests and the neighbors privacy and
security. The field fence was chosen for the western half of the boundary to cut down on cost and
to allow wildlife to move under and through the contiguous wooded areas.

4.0 Future Use of the Logan Woods Preserve Including
Management Issues, Goals and Objectives
This section describes the main management issues, goals, and objectives for Logan Woods
Preserve as well as the overall management framework. Central to the management of the preserve
is the mission of the Conservation Collier Program, and the goals and objectives set forth in this
management plan.
4.1 Management Plan Framework
Each property purchased by Conservation Collier shall have its own management plan. At the
time the property was purchased, the Conservation Collier Ordinance required that an “Interim”
Management Plan be developed within 60 days of closing. Interim plans include basic items such
as removal of invasive exotics and trash, establishing site security, developing management
partnerships and planning for public access. The interim plan for this site was officially approved
in January 2006. The ordinance then requires a “Final” management plan be developed in two
years. Subsequently, the property management plan must be updated every five years. Final
management plans, however, are considered living documents and can be updated at any time. All
management plans are first reviewed by the Lands Evaluation and Management Subcommittee
and must be approved by both the CCLAAC and the Board of County Commissioners.
4.1.1 Preserve Manager: Contact Information
The Site Manager for Logan Woods Preserve will be a designated Collier County Environmental
Specialist who may be contacted through electronic mail: ConservationCollier@Colliergov.net.
4.2 Planned Uses and Assessment of their Impacts
Future planned use will be consistent with the primary goals of conservation, preservation,
restoration and maintenance of the resource. Official public use of the site began in October 2009,
when the created trail was opened to the public. Details of planned uses for the Logan Woods
Preserve and an assessment of their potential impacts are provided in the following sections.
4.2.1 Identification of Public Uses Consistent with Preservation, Restoration, and Conservation
of the Resources
The Conservation Collier Ordinance 2002-63 constrains the use of this property to “primary
objectives of managing and preserving natural resource values and providing appropriate natural
resource-based recreational & educational opportunities.” Natural resource-based recreation shall
mean all forms of uses, which are consistent with the goals of this program, and are compatible
with the specific parcel. Such uses (as possible on specific preserve lands) may include, but are
not limited to: hiking, nature photography, bird watching, kayaking, canoeing, swimming, hunting
and fishing (Ord. No. 02-63, § 5, 12-3-02). Additionally, 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
35
plant communities and animal species. Collier County Ordinance 2011-38 governs use of this
preserve.
Of the uses listed above, the following are appropriate for this particular site: hiking, picnicking,
nature photography, and bird watching.
In addition, there are no existing concessions, or leases at the Logan Woods Preserve. The
County’s Transportation Department owns a Right of Way (ROW) easement on the eastern and
southern portions of the preserve totaling 1.80 acres, leaving a total of 5.69 acres for conservation.
In accordance with the management goals of the preserve, no additional future easements,
concessions, or leases are appropriate in association with this site, other than conservation related
easements.
4.3 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.
Conservation Collier staff have noted a significant change in the hydrology of the preserve since
its nomination to the program in 2003. Currently, the western and northern areas of Collier County
are in a severe drought status, while the rest of Collier County remains in a moderate drought status
(NOAA/NWS 2008). While these drought conditions remain, the succession of the plant
community is difficult to predict. However, after managers complete recommended management
actions, Logan Woods Preserve will likely consist of a Cypress-Pine-Cabbage Palm Community.
With the exception of a mulched trail, the site will stay naturally vegetated with appropriate native
flora that will provide suitable cover for a variety of wildlife species.
Cypress- Pine-Cabbage Palm Community will be comprised of native canopy species
such as: cypress, slash pine, cabbage palm, and bay. Native midstory species will include:
myrsine, willow, buckthorn, marlberry, wild coffee, saw palmetto, beautyberry,
buttonbush, salt bush (Baccharis halimifolia) golden polypody and dahoon holly. The
understory will be comprised of swamp fern, giant hatpins, yellow-eyed grass, fringed
yellow-eyed grass (Xyris fimbriata), Southern dewberry (Rubus trivialis), catbriair (Smilax
sp.), chain fern, spider-lily, , muscadine, Virginia creeper, a wide variety of grasses
(Agrostis, Andropogon, Aristida, Dichanthelium, Eragrostis, and Panicum spp., etc.), and
composites (Aster, Chrysopsis, Emilia, Eupatorium, Liatris, and Solidago spp., etc.). A
current list of plants identified within the preserve may be found in Appendix 2.
4.4 Goals for the 10-year period 2008-2018
A set of goals and objectives for Logan Woods Preserve were developed in conjunction with the
drafting of this Management Plan. The goals and objectives in this plan are tailored specifically
for Logan Woods 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 Logan Woods 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
36
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 Logan Woods Preserve:
Goal 1: Eliminate or significantly reduce human impacts to indigenous flora and fauna
Goal 2: Maintain a longterm vegetation/wildlife Develop a baseline monitoring program
Goal 3: Remove or control populations of invasive, exotic or problematic flora and fauna
Goal 4: Restore native vegetation and maintain natural habitats
Goal 5: Develop a plan for public use
Goal 6: Facilitate uses of the site for educational purposes
Goal 7: Provide a plan for security and disaster preparedness
GOAL 1: ELIMINATE OR SIGNIFICANTLY REDUCE HUMAN IMPACTS TO INDIGENOUS
FLORA AND FAUNA
In addition to the chain-link fence on the western border of the preserve and the recently installed
fence on the northern border of the preserve, the following actions will be performed:
Action Item 1.1 Install signs encouraging people to stay on any future public access
trails situated on the Logan Woods Preserve.
Action Item 1.2 Identify locations of rare and listed native plant species.
Rare and listed species will be monitored by staff and changes in populations will be noted in
management logs. If listed plant populations start to decline, and management actions are
warranted or applicable, those actions will be taken. Trails will be constructed to avoid areas
where rare and listed species exist.
Action Item 1.3 Enforce regulations prohibiting trash or dumping in the preserve.
Staff will monitor the trails on a regular basis and if excessive dumping or littering start to
occur, enforcement actions will be sought through the Sheriff’s Department.
Action Item 1.4 Identify actual and potential locations of resident animal life and take
steps such as locating visitor amenities away from animal nesting sites.
37
Action Item 1.5 Avoid non-target damage to native plants and animals, especially rare
species, during invasive, exotic plant treatments.
Licensed County or State contractors will be monitored closely to ensure the proper herbicide
applications are being utilized while treating the site. From 2008 on, staff will prohibit the use
of Imazapyr containing herbicides such as Arsenal on the preserve. This type of herbicide has
potentially caused a great deal of non-target damage throughout the state.
Action Item 1.6 Note and research all site development occurring adjacent to Logan
Woods Preserve to determine that the proper site development permits have been
obtained and that the site development complies with the permits.
Future activities on adjacent lands may have an impact on the indigenous plant and animal life
on the Logan Woods Preserve. As such, 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. Staff will work together with the Community
Development and Environmental Services Department to achieve compliance if problems arise.
GOAL 2: MAINTAIN A VEGETATION/WILDLIFE DEVELOP A BASELINE MONITORING
PROGRAM
Action Item 2.1 Establish Maintain a long-term biological monitoring program and
conduct additional wildlife surveys.
Long-term management of the preserve should be based on biological data. Changes following
baseline conditions should be assessed as negative or positive, and management strategies
changed appropriately. This section discusses information needs and long-term monitoring
needs.
A floristic survey was conducted by Conservation Collier staff. This will comprise the
baseline floristic data on which future actions will be based. The site should be inspected by
Conservation Collier staff at least twice a year and thoroughly inventoried at regular intervals
(ca. 5-10 years) to detect new invasions (by natives or exotics), and extinctions. Areas
undergoing extreme restoration should be assessed more frequently. While some wildlife data
has been collected, additional baseline data should be collected, especially on invertebrates,
small mammals, reptiles, and amphibians. The site manager may contract this work out or
enlist the assistance of local educators to coordinate student research projects. Wildlife
sampling, like plant sampling, should take place at regular intervals (ca. 5-10 years) to detect
long-term trends.
To date, three (3) photo points have been established in and across from the preserve (Figure
11). Locations of photo points have been recorded with a GPS and all photographs taken at
these locations have been taken at a standard height and angle of view. One (1) photo point
was established within the boundaries of the preserve. During photo documentations of this
point, one photo is taken in each of the cardinal directions (north, east, south and west) and a
38
360-degree panoramic photo is taken. One (1) photo point was established on the eastern side
of Logan Blvd across from the preserve. During photo documentations of this point, a 180-
degree panoramic photo is taken from south to north. The third photo point is located on the
southern side of Pine Ridge Road across from the preserve. During photo documentations of
this point, a 180-degree panoramic photo is taken from west to east. These photos will help to
monitor exotic removal and native plant recruitment over time. If necessary, more photo points
will be established to aid in management decision activities. Appendix 5 shows before and after
photos from these photo points, as well as the most current photo point photos.
Figure 11: Photo Point Locations at Conservation Collier’s Logan Woods Preserve
GOAL 3: REMOVE OR CONTROL POPULATIONS OF INVASIVE, EXOTIC OR
PROBLEMATIC FLORA AND FAUNA
Action Item 3.1 Acquire services of licensed and qualified contractor(s) for the removal
of invasive, exotic or problematic plant species.
Initial exotic removal was conducted in May 2007 and since then, follow-up treatments
occurred every 3 months through May 2008, and following that, twice annually through 2013.
PP
ending a plant inventory, maintenance events may be reduced to annually in perpetuity.
39
The following (Table 8) describes recommended controls of the majority of the Category I and
II, invasive, exotics by Langeland and Stocker (2001) as well as staff recommendations. These
recommended control methods may be altered by site managers dependent on new information
and products available on the control of these species. Staff has added to the table the hand
pulling of small seedlings to avoid the overuse of herbicides. Appendix 4 provides a table of
the description/biology of these plants from Langeland and Stocker (2001).
Table 8: Invasive, Exotic Plant Species Control Plan
for the Logan Woods Preserve: Category I species
Scientific Name Common Name(s) Recommended Control(s)
Acacia
auriculiformis earleaf acacia Hand pull seedlings, Basal bark application of 10% Garlon 4 or
cut-stump treatment with 50% Garlon 3A.
Cupaniopsis
anacardioides carrotwood
Hand pull seedlings, basal bark application of 100% Pathfinder
II, or 10%-20% Garlon 4 diluted with oil; or cut stump
application of 10% Garlon 3A, 100% Brush-B-Gon, 100%
Roundup Pro, 100% Rodeo, or equivalent glyphosate
containing product, or 100% Pathfinder II.
Dioscorea
bulbifera air-potato
A basal stem application of Garlon 4 is recommended although
cut-stem treatments with 50% Garlon 3A or 10% Garlon 4 are
also effective. If bulbils are present on vines, a basal bark
treatment should be used because it will translocate into the
bulbils. Collect bulbils from the ground and remove from site.
Apply 10% Garlon 4 to stems emerging from tubers. Hand
pulling followed by treatment of re-sprouts has also been
effective. Foliar applications of Garlon 1%-2% 3A has been
effective. Several applications throughout the growing season
may be necessary.
Lygodium
microphyllum
old world climbing
fern
Control immediately upon sighting. Thoroughly spray foliage to
wet with 1.25% Garlon 4 (4 pt per acre), 0.6% Roundup Pro
(maximum 5 pt/acre), or 1.0%-3.0% Rodeo (maximum 7 pt per
acre). Only Rodeo can be used if plants are growing in aquatic
sites. The poodle cut method may also be used for plants
growing high into trees- cut vines and treat lower portions. Do
not apply when plants are under environmental stress.
40
Vines - particularly muscadine (Vitis rotundifolia) - may become abundant after mechanical
treatments or exotic plant removal. This native vine, already present in low densities, can
become invasive after disturbances - forming dense colonies, killing hardwoods and palms,
climbing into canopy species, and persisting for years. Vitis sp. should be controlled by cutting
and foliar treat with herbicides if its populations start to take over. This has not occurred, but
will be monitored with notation in the management site activity log maintained by the site
manager.
Action Item 3.2 Acquire services of licensed or qualified contractor(s) for the removal of
invasive, exotic or problematic animal species.
To date, two (2) introduced animal species have been documented on the Logan Woods
Preserve, the Red Imported Fire Ant (RIFA) and the brown anole. It is doubtful that the total
eradication of these species can be achieved. However, staff and/or contractors should take
measures to remove RIFA populations close to or on public access trails. This is being done as
needed. With notation in the management site activity log maintained by the site manager.
Table 8 cont’d: Invasive, Exotic Plant Species Control Plan
for the Logan Woods Preserve: Category I species (continued)
Scientific Name Common Name(s) Recommended Control(s)
Melaleuca
quinquenervia
melaleuca, punk
tree, paper bark
For seedlings and saplings: (1) hand pull, being sure not to break
plant off of root system and remove or place in piles to help
reduce the chance that they will re-root or; (2) Treat with foliar,
low volume spot application of 5% Rodeo. For mature trees: (1)
Fell large trees with chain saw leaving a level surface, or fell
small trees with machete and treat with triclopyr or glyphosate
or aquatic Garlon (renovate) products according to frill and
girdle directions on SLN label. Use aquatic versions where
standing water is present. Monitor for resprouting and retreat as
necessary. (3) Mature trees are very difficult to control with
foliar applications.
Rhodomyrtus
tomentosa downy rose myrtle Hand pull seedlings, basal bark application of 10%-20% Garlon
4 or Foliar of 6qt per acre of Vanquish (dicamba)
Rhynchelytrum
repens rose natal grass Foliar-2.5% Glyphosate mixed in water with non-ionic
surfactant, treat in spring prior to seed set
Schinus
terebinthifolius Brazilian pepper
Hand pull seedlings. Cut-stump treatment with 50% Garlon 3A,
10% Garlon 4 or a basal bark application of 10% Garlon 4.
Foliar application of Garlon 4, Garlon 3A, Roundup Pro,
Roundup Super Concentrate, or Rodeo, according to label
directions may be used where appropriate. Glyphosate products
are less effective when used alone in spring and early summer.
Use Rodeo where plants are growing in aquatic sites.
Syzygium cumini java plum,
jambolan
Mature trees may take up to 9 months to die. Cut-stump
treatment with 50% Garlon 3A or 10% Garlon 4, or use a basal
bark treatment with 10% Garlon 4.
Tradescantia
spathacea oyster plant Hand pull and remove from site.
Urena lobata ceasar’s weed Hand pull seedlings, Foliar treatment with 2-5% Glyphosate in
water can be sprayed on young plants. Its best to treat in the
spring or summer prior to seed maturation.
41
If feral cat colonies are found near the preserve, the elements that sustain the undesirable
population(s) should be identified and efforts made to ask property owners to eliminate them
(i.e., refuse bins, dumpsters, and supplementary feeding by humans). If any feral cats remain,
they will be trapped and taken to Collier County Domestic Animal Services. No feral cats have
been observed within the preserve.
GOAL 4: RESTORE NATIVE VEGETATION AND MAINTAIN NATURAL HABITATS
Action Item 4.1 Maintain a revised GIS map and description of FNAI natural
communities and disturbed areas on the property.
Maintaining updated maps will help to guide restoration efforts.
Action Item 4.2 Plant additional native plant species in their appropriate habitats
Periods following exotic removal are essential to the recruitment of native plants. If native plant
recruitment is not sufficient from the surrounding, intact seed source, efforts will be made to
plant indigenous flora in appropriate habitats. Natural area restoration of Logan Woods
Preserve should include only site-specific native plant material that has been determined to be
non-problematic at the site and whenever possible, site-specific seed sources should be utilized.
Planting should occur in early June of each year at the start of rainy season. Recommended
date to start replanting is June of 2009. This will be contracted out or volunteer work days will
be held to involve neighbors and scout groups. Grants may be sought to assist in funding
depending on cost. No additional plantings have been deemed necessary up to time of this plan
update in 2013.
GOAL 5: DEVELOP A PLAN FOR PUBLIC USE
Action Item 5.1 Develop Access and Required Facilities for Intended Public Uses
A parking lot is not planned to be constructed on the site due to the amount of wetlands present,
and to the small size of the site. Parking for the site is available along Sycamore Drive to the
north of the site and many neighbors may walk or bike to the site. ADA (American with
Disabilities Act) access is available around the outside perimeter via the sidewalks along Logan
Blvd. and Pine Ridge Road. Additional access features are depicted in the conceptual level
master plan (Figure 12).
A trailhead into the preserve has been created off the sidewalk bordering Logan Blvd. An
interpretive sign and bike rack are located just west of the ROW easement off Logan Blvd. A
trail arches in a southwesterly direction and connects to the sidewalk north of Pine Ridge Road.
A picnic table and, bench, trash and recycling receptacles have been installed. The main trail
is approximately 840 feet long.
42
Figure 12. Logan Woods Preserve Site Plan
43
GOAL 6: FACILITATE USES OF THE SITE FOR EDUCATIONAL PURPOSES
Actions Item 6.1 Develop interpretive signage to educate preserve visitors.
Once a trail system is complete, site specific signage will be developed to educate visitors on plant
identification and ecosystem information. A specific sign will be made about invasive exotics with
before and after photos to show how the site was transformed. This sign may also illustrate the
partnerships involved in removing the exotics in this area.
Action Item 6.2 Provide preserve brochures in rainproof box on site.
An educational brochure outlining the native plant communities present at the preserve will be
created by County staff. It will also provide information about invasive exotics. A rainproof box will
be installed near the preserve entrance(s). The box will be inspected monthly by the Preserve
Manager and refilled as necessary.
GOAL 7: PROVIDE A PLAN FOR SECURITY AND DISASTER PREPAREDNESS
Action Item 7.1 Discourage visitation to the park at night.
A sign designating park hours as dawn to dusk had been installed at the entrance to the preserve off
Logan Blvd. and adjacent landowner and homeowner association have been provided an emergency
phone number if they detect human activity on the preserve after hours. If problems arise, the Collier
County Sheriff’s Office will be contacted to patrol the area on a routine basis.
Action Item 7.2 Survey trees along the trail and the perimeter of the property annually for
damage
Staff will utilize the services of a certified arborist, which could be a staff member, to determine
diseased, weak, or damaged trees/limbs surrounding the trails, benches and picnic tables that should
be removed for safety reasons and prior to hurricane season. This activity is intended to reduce the
risk of visitor injury. There are also some melaleuca trees that were killed in place on the private
property adjacent to the preserve. The property owner has granted permission to cut down any of
the dead trees that may start to lean towards the preserve or the Vineyards community that could
potentially damage either fence.
Action Item 7.3 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 7.4 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. Removal of debris and damaged or downed trees along
the trail system may be needed. Downed trees and limbs that do not appear to be a public safety
44
hazard will be cleared at the discretion of the Preserve Manager. The trees that may have fallen into
the road ways or adjacent sidewalks will be the responsibility of the Transportation Department as
they own the easement. As much hurricane debris as possible will be chipped and retained on-site –
to be used as mulch for the trail.
4.5 Operational Plan for the Logan Woods Preserve
This section provides management recommendations for operation of the Logan Woods Preserve. It
discusses maintenance and budgeting needs, the possibilities for contracting the restoration activities,
coordination, and other management issues.
4.5.1 Maintenance
The primary maintenance activities for the preserve will include maintaining the trail, fence and signage
and to control dumping and littering within and around the preserve. The mulched portions of the trail
will be replenished every few years as the mulch breaks down. The Sheriff’s Department Weekend
Work Program crews can be utilized to lay mulch and to pick up debris within the preserve and along
the two main roadways. The garbage cans on site will also need to be emptied on a weekly or bi-weekly
basis, this can be done by Program staff or will be contracted out.
4.5.2 Estimated Annual Costs and Funding Sources
Preliminary budget estimates for Logan Woods 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. Table 9 shows
the activities planned for the next ten years and the initial and annual cost estimate of each activity.
Private and public organizations may also provide funding for specific projects.
Funding already secured and utilized for management activities at Logan Woods Preserve include a
grant from the Florida DEP Bureau of Invasive Plant Management ($38,000) to conduct the initial exotic
removal and/or treatment. Additional grants may be sought to supplement existing management funding
to possibly fund trail construction, supplemental planting and signage. Staff will also continue to utilize
the Collier County Sheriff’s Department Weekend Work program for certain labor projects and may
also separately involve the County Scout programs for trail enhancement or other related projects.
The budget in Table 9 represents the actual and unmet budgetary needs for managing the lands and
resources of the preserve. This budget was developed using data from Conservation Collier and other
cooperating entities, and is based on actual and estimated costs for land management activities,
equipment purchase and maintenance, and for development of fixed capital facilities. The budget below
considers available funding and is consistent with the direction necessary to achieve the goals and
objectives for Logan Woods Preserve.
