SUBJECT: Everglades Private Airboat Tours (CU-92-26)
Wildlife Monitoring Reports
I am writing this memo in response to the request for technical
assistance to evaluate the wildlife (bird) surveys for the above
referenced project. In order to evaluate the surveys, I first
had to understand the original intent of the requirement.
According to the development order stipulations the applicant was
required to , submit to Project Plan Review Environmental Staff for
review and approval, a monitoring program to assess possible
impacts to the natural resources of the area within the
conditional use boundaries, specifically impacts to avian
species. Unfortunately, a detailed, written monitoring plan was
never included within the following development process, the Site
Development Plan (SDP-93-80) approved on October 25, 1993 .
However, the applicant did contact the Florida Game and Fresh
Water Fish Commission (FGFWFC) for technical assistance during
the beginning of the development review process. On July 17 ,
1994 , FGFWFC Biologist IV, Kimberly A. Dryden, forwarded a letter
including her comments and observations from her joint site
inspection with the U. S. Fish and Wildlife Service (USFWS) to the
applicant, Mitchell House. In the letter she mentioned that the
limitations imposed by the low number of survey events (once
during the wet season and once during the dry season, over a five
year period) recommended as a minimum by the County will be
somewhat ineffective in allowing any comparison of potential
wading bird utilization of the project overtime. She also stated
that only long-term data can be utilized to make conclusions
regarding such impacts, due to the variability in weather (cold
fronts) , water depth, visibility, and potential number of
airboats utilizing the area during survey events. The only
general recommendations pertaining to the County's requirement
which she made are as follows:
1) Observations should be made at the same location, same
time of year, and most importantly, at the same water
depth, to make surveys as consistent as possible.

2) To assure consistency in determining water depth, staff
gauges should be erected at sample sites.
3) Surveyors should be qualified to identify those species
utilizing the site. I would recommend that the local
Audubon Society be contacted to provide some
assistance.
4) I would recommend an increase in wet season surveys, and
a decrease in surveys during the dry season, when
utilization by birds would be more limited than at other
times of the year. Wet season surveys should
concentrate on migration periods and periods when
wetlands begin to draw down, and forage fish and other
bird prey become concentrated. If the survey events
were increased in number, dry season surveys, especially
in airboat trails, would add to the baseline data for
the area.
5) Note preference of avoidance of airboat trails by each
species.
Since the original Conditional Use approval (CU-92-16) , the
applicant has submitted three bird surveys (See attached) . All
of the surveys include the following: surveyor(s) name; weather
conditions; and a list of bird names and quantities. One of the
surveys, the first includes a one and a half hour time frame.
Many of the bird names do not correspond to the vernacular names
adopted by the American Birding Association or represent the
scientific names decreed by the American Ornithologists Union.
Although it not specifically stated, the quantities which are
oriented next to each bird name may represent the numbers of
individuals observed by the surveyor(s) .
The applicant's bird surveys do not meet any standardized set of
survey requirements in order to provide sufficient detail to
allow a meaningful evaluation of the impact of a proposed land
use on avian species. There are corresponding survey
methodologies designed to aid in determining the on-site status
of species within wetland and upland habitats. Staff typically
references the Wildlife Methodology Guidelines for Section 18 . D
of the Application for Development Approvals published by the
FGFWFC and any additional technical assistance provided by the
FGFWFC and/or USFWS.

V. STAFF COMMENTS:
Water Management:
The water management system to serve the project will consist of a
lake of approximately 0. 6 acres interconnected with 1. 05 acres of
dry detention. Runoff from the developed areas will be conveyed
to the lake and dry detention areas by catch basins, culvert
system and swales. The lake and retention areas will then
discharge through culverts into a spreader swale adjacent to the
preserve. The spreader swale will bleed down into the preserve
area through intermittent bleeder pipes. The preserve area is
included in the surface water management system for quantitative
storage and re-establishment of natural hydroperiods.
Offsite discharge will be through a control structure located at
the southeast corner of the project. This discharge will be
conveyed by an existing ditch into Haldeman Creek to the south.
Post construction discharge will be 1. 52 cfs (0. 06 cfs/acre
maximum) . This project will be permitted by South Florida Water
Management District (SFWMD) .
Environmental:
The subject property contains approximately 17 acres of
jurisdictional wetlands and approximately 13 acres of uplands.
The wetlands are made up of 7 acres of cypress (Taxodium
distichum) forest under a County Special Treatment (ST) zoning
designation, and 10 acres of disturbed hydric flatwoods (This area
was hydro-axed in March 1995) .
Within the ST area the predominant vegetation is cypress (Taxodium
distichum) , swamp fern (Blechnum serrulatum) , dahoon holly (Ilex
cassine) , wax myrtle (Myrica cerifera) , flag, saltbush (Baccharis
halimifolia) and Brazilian pepper (Schinus terebinthifolius) . The
consultant indicated that the water depths at the time of her site
EAB Meeting 2/7/1996
PUD-95-14, David A. Gallman Estates PUD
Page 3
visit were 6 to 18 inches above ground. The disturbed hydric pine
flatwoods contains a canopy of slash pine (Pinus elliottii) and
and understory of swamp fern, melaleuca (Melaleuca spp. ) , and
various sedges and rushes.
The upland areas are made up of 2+ acres of xeric oak habitat and
11+ acres of pine flatwoods with a rapidly regenerating
understory which had been totally destroyed during the exotic
removal process done by hydro-axed.
The xeric oak area is located at the northwest corner of the
property. Predominant vegetation here includes live oak (Quercus
virginiana) , saw palmetto (Serenoa repens) , penny royal
(Piloblephis rigida) , assorted vines and weedy groundcover.
Thirteen active and inactive burrows were identified and flagged
in this area. It is estimated that five tortoise occupy these
burrows. One quarter of this habitat ( . 5 acre) will be preserved
and used to protect the tortoise during development. The proposed
development will impact approximately 30% of the wetlands leaving
the quality wetlands (under ST designation) in place with a water
management plan to maintain or improve the hydroperiod.
VI. RECOMMENDATIONS:
Staff recommends approval of Planned Unit Development Petition No.
PUD-95-14 , "David A. Gallman Estates PUD" with the following
stipulations:
Water Management:
1. A copy of South Florida Water Management District (SFWMD)
Permit or Early Work Permit with staff report is required
prior to construction plan approval.
2 . An Excavation Permit will be required for the proposed lake in
accordance with Division 3 . 5 of Collier County Ordinance NO.
92-73 and SFWMD rules.
3 . Developer shall dedicate a thirty foot (30' ) wide drainage
easement along the north boundary of the project to encompass
the top width of the adjacent ditch that lies within the
property and provide for a maintenance access travel way along
the south side of the ditch.
4 . Prior to final site development plan approval, developer shall
provide evidence that there is sufficient capacity for the
existing drainage ditch to Haldeman Creek that serves as the
project's outfall at the southeast corner of the project.
