The Gopher
Tortoise
Council
|
 |
In
1978, a group of southeastern biologists and other citizens concerned with the
decline of the gopher tortoise (Gopherus polyphemus) formed the Gopher
Tortoise Council (visit GTC
website). Their goal is to work for the wise management and
perpetuation of the gopher tortoise, the animals that live with it and their
natural habitats.
The Gopher Tortoise
A gopher tortoise's life revolves
around its burrow, which can be up to 40 feet in length and 10 feet in depth.
The tortoise digs its burrow with its shovel-like front legs. The width of the
burrow is approximately the same as the tortoise's length, enabling the tortoise
to turn around anywhere in its burrow. Gopher tortoise burrows are the lifeblood
of dry, sandy uplands.
Because these environments are
desert-like, the burrows, which remain at fairly constant temperatures and high
humidity throughout the year, provide shelter for more than 360 species of
animals including indigo snakes, gopher frogs, Florida mice, skunks, opossums,
rabbits, quail, armadillos, burrowing owls, snakes, lizards, frogs, toads and
many invertebrates.
- Range of the Gopher Tortoise
Gopher
tortoise populations are scattered throughout the Coastal Plain of the
southeastern United States, with most being found in north-central Florida and
southern Georgia. The species has been severely reduced in southern Alabama and
Mississippi, southeastern Louisiana, southeastern South Carolina, and along
Florida's southeast coast and throughout much of the Florida panhandle.
- Gopher Tortoise Reproduction
Gopher
tortoises normally mate during April and May. Several weeks after mating, female
tortoises lay up to 25 eggs, usually in the sand mounds in front of their
burrows or in some other nearby sunny place. After hatching, young tortoises
either live in their mother's burrow or dig a small tunnel near her burrow.
- the Florida Gopher Frog, a closely
associated species
The Florida gopher frog (Rana
capito) lives in dry wooded habitats where there are gopher tortoise burrows
in which it makes its home. This species of frog is seldom seen during the
daylight hours and is mainly active at night. During the day it will retreat
into the damp burrows of gopher tortoises or into other cavities. Gopher frogs
are best seen when they are calling from breeding ponds, which may be a mile or
more from their home. They breed mostly during the winter and early spring.
Why is the gopher tortoise in trouble?
The
gopher tortoise is declining throughout its range. Recent studies project that
this species may not exist outside of protected areas for much longer unless
something is done to reverse this decline.
- Urban Development and Agriculture
Habitat destruction poses the most serious threat to the continued survival
of the tortoise in much of its range. Both people and tortoises like to live
in the high dry areas of the southeastern United States. Habitat conversion
for agriculture is also a serious threat, since high and dry areas are
preferred by both farmers and tortoises.
- Road Mortality
Many tortoises are killed each year by automobiles. Highway mortality will
increase as tortoise populations become enclosed and fragmented by more and
more roads. Construction of roads further isolate tortoise colonies.
However, it is possible to build roads with underpasses or other structures
that allow tortoises and other wildlife to pass safely beneath.
- Inadequate Protection and Law Enforcement
Gopher tortoises are protected throughout their range. Florida and Georgia
classify the tortoise as a non-game species and require a scientific
collecting permit for possession. Florida, which lists the tortoise as a
Species of Special Concern, requires a permit to keep gopher tortoises as
pets. Alabama designates the gopher tortoise as a game animal but specifies
that there is no open season during which it may be lawfully hunted, taken,
caught, captured, or killed. Both South Carolina and Mississippi list the
tortoise as an Endangered Species. In addition, gopher tortoises west of the
Tombigbee and Mobile Rivers in Alabama are listed by the U.S. Fish and
Wildlife Service as Threatened under the Endangered Species Act.
Unfortunately, even with these laws and enforcement, gopher tortoise
populations are still in decline. More protection is needed to ensure the
survival of today's gopher tortoise populations.
What can be done to preserve gopher
tortoises and their burrow associates?
- Help raise awareness in your community to
increase the protection of gopher tortoises and their burrow associates.
- Support legislation to protect threatened
and endangered species in your state.
- Support natural habitat management and
restoration programs.
