Gopher Tortoises in Louisiana
Reptile: Gopherus polyphemus
Besides the Common Box Turtle, another land turtle, the Gopher Tortoise (Gopherus polyphemus), inhabits our area in Southeastern Louisiana. These reptiles are uncommon and are on the federally protected list in Louisiana, Mississippi and western Alabama. It is a species of conservation concern throughout its range.
The tunnels that the tortoises dig are very important to the ecosystem in which they live. Countless numbers of other species of animals take shelter in the tunnels during times of crisis.

Tortoise Habits and Habitat
In Louisiana, Gopher Tortoises are only found in the southeastern portion of the state, in the Florida Parishes. They tend to prefer areas with deep sandy soil, where it is easier to dig their burrows, but are sometimes found in areas with clay soil. Traditionally they occupied the savannas of the Long-leaf Pine forests that once spread across the southeastern part of the state. Now they are found in open areas such as right of ways, field edges and fencerows.
Gopher Tortoises are the only southeastern turtle that digs its own burrows. Even hatchling tortoises are capable of digging their own burrow shortly after the leave the nest. The burrows are quite long, averages 15 feet and angling down 6 feet below the surface. The width of the burrow is about the same dimensions as the length of the tortoise because the tortoise has to be able to turn around in it.
Most of the Gopher Tortoise's life is spent underground in its burrow, though it will visit other turtles in their burrows. They are most active from May through September and during warm weather at other times of the year.
These tortoises are mostly vegetarian, although they have been observed, on occasion, feeding of carrion, feces and old bones.

Reproduction and Predators
Gopher Tortoises have only one nest each year. Courtship occurs in the fall. Females lay a clutch of 3-9 ping pong shaped eggs in a nest usually just outside or in the opening of the her tunnel in May to early July. They hatch in late August to early October.
There are many predators of the eggs, hatchlings and small juveniles including racoons, opposums, foxes and skunks. Large snakes including coachwhips and indigo snakes can take the young while their shells are still soft. Fire ants are also a problem for eggs and young.
Coyotes, bobcats, feral dogs and large raccoons sometimes prey upon adult tortoises.

Conservation Issues of Gopher Tortoises
Gopher Tortoise populations are on the decline and some individual populations are close to extinction.
In the past, many tortoises were killed for consumption. Additionally, their burrows were gassed to collect Diamond-backed Rattlesnakes that dwell in the burrows during winter and early spring. These influence have negatively impacted the repopulation of this long lived, but low reproducing species.
Gopher Turtles have also suffered from a respiratory disease.
As with the other land turtles in Louisiana, habitat destruction and fragmentation have reduced many populations.
For this species to make a comeback they must be protected and remaining habitats and individual populations must be intensively managed.
