GREENWAYS & NATURAL LANDS
Reptile Monitoring

All Reptiles
and Amphibians observed will be recorded
in the base inventory. The principle methods
of herptile sampling
will be through drift
fences and coverboard transects.
Drift fences are often constructed at the
margins of small water bodies (e.g. depression
marsh) and at other areas of high animal
movement.
Drift fences and
coverboards will be checked for five (5)
consecutive days each quarter. All herptiles
(and other vertebrates) captured will be
identified to species, and morphometric data
will be collected prior to their release
at site of capture. In order to identify
herptiles that are recaptured, all captures,
excluding venomous snakes, will be marked
via toe clipping (for frogs, lizards, etc.)
(Figure
1), scale clipping (for snakes) (Figure
2), or notching the shell (for turtles)
(Figure
3).
Wetland areas
on several Natural Lands parcels serve as
reproductive sites for many species of amphibians.
Nighttime and rain event surveys will be
conducted at least once quarterly as a means
of assessing general species diversity.
Gopher
tortoises inhabit several of the SCNLP wilderness
areas and will be further discussed
in the section addressing listed
species. Voucher
specimens of common species collected
may be preserved and placed in the University
of Central Florida vertebrate collection
MONITORING PROTOCOL |
|
FENCES (Every
Natural Land has at least one drift
fence on it. ) |
|
The investigator
should open all pit falls and place
funnel traps in the appropriate positions
by two hours before sunset. |
|
All traps
should be well shaded with wood or
vegetation (palmetto fronds) to keep
captured animals cool. Each pit fall
trap should also contain at least
one sponge to keep amphibians from
drying out. |
|
All traps
should be checked before eleven a.m.
each day that they are open. |
|
When
arriving at the site a temperature.
and humidity should be recorded. |
|
When
checking pit fall traps the investigator
should dig down through any dirt
to make sure no animals are buried. |
|
When
checking the funnel traps the traps
should be picked up and examined DO
NOT SIMPLY SHAKE THE TRAP- THIS
WILL RESULT IN MISSED ANIMALS.
Some live
insects may be left in the funnel
traps as this may attract some
amphibians. |
|
No live
or dead animals should be left in
the buckets. |
|
If ants
are in the pit-falls bring "Amdro" the
next day to get rid of them. |
|
When
finishing the trap check, replace
all the traps in the correct way.
Make sure the funnel traps are placed
below the level of the surrounding
substrate!! |
|
|
COVERBOARDS |
|
Coverboards should be checked on
the first and last day of the trapping
event. |
|
When running out of time, check the
fences first- do not check the coverboard
transects first. These boards can be
checked at any time. |
|
All boards should be quickly raised
and litter under boards should be mixed
to determine if there is any animal
hiding. |
|
The standard measurements should
be taken on any animal found under
these boards |
|
|
MINNOW
TRAPS |
|
Minnow traps may (but are not required
to be set) at any trapping event were
there are bodies of water. |
|
If traps are set they should be checked
before eleven a.m. |
|
The trapping protocol
is slightly different than when using
these for
fish. When trying to capture herps.
The traps should be set with at least
some portion of the trap out of the
water. These traps perform better
when app. ½ of the trap is out of
the water. |
|
All measurements and other protocols
are the same (see fish
sampling) |
