The southeastern pocket gopher appears to have disappeared from much of
its former range in Georgia, prompting the Georgia Department of Natural
Resources, Wildlife Resources Division (WRD) to launch a two-year survey
and population assessment for the species. Although they are a secretive
and little-known species, these burrowing rodents play a dynamic role in
Georgia’s natural history.
The study began in July and will detail the former territory and current
range of the gophers, as well as identify potential threats and plan for
their conservation. Like gopher tortoises, pocket gophers are considered a
keystone species because their underground homes benefit other plants and
animals.
“Pocket gophers are particularly important in Georgia because a number of
invertebrates depend on their burrows for survival,” said WRD Sr. Wildlife
Biologist Jim Ozier. “The gophers also help to loosen soil and provide the
conditions some plant species need for germination.”
Pocket gophers (Geomys pinetis) need loose, easily crumbled soil for
burrowing. They also require areas with a groundcover of flowery or grassy
vegetation because the browse the roots of these plants. The gophers were
once more common across the coastal plain of southern Georgia, southern
Alabama and most of Florida.
The species has been in decline due to the loss of much of its natural
habitat – longleaf pine savannas and naturally vegetated rolling sand
hills. Development and intensive agricultural and silvicultural practices
have reduced the amount of suitable habitat for pocket gophers, leaving
very few known remaining populations on small, isolated sites.
Pocket gophers are sometimes called “salamanders.” This nickname is
probably derived from the term “sandy mounders,” as their burrows are
marked by numerous small mounds of sandy soil. Though the mounds could be
seen as a nuisance in certain settings, WRD encourages any landowner whose
property contains burrows to welcome their presence.
The study will begin with compiling information on the gopher’s historical
range, followed by mapping current sites and determining potential threats
to the species. Finally, biologists will develop a plan to monitor and
manage Georgia’s pocket gopher populations.
Though this nongame species is protected by state law, some lawn and
garden stores sell poison intended to eradicate unwanted gophers. Part of
the WRD study will examine habitat management and non-lethal options for
removing any remaining gophers that appear to present a problem.
“Our research will document the decline of pocket gophers in Georgia,
identify remaining habitat and discuss steps to ensure the long-term
survival of this species,” Ozier said.
Pocket gophers have been identified as one of Georgia’s high priority
mammals in the Comprehensive Wildlife Conservation Strategy, a state and
federally funded plan that will guide future conservation efforts in the
state. Much of the funding for the pocket gopher study and the development
of the state’s wildlife conservation strategy comes from a federal grant
program called State Wildlife Grants. A draft of the wildlife conservation
strategy and information on State Wildlife Grants can be found at

Georgians can support the conservation of nongame wildlife by purchasing a
bald eagle wildlife license plate for their vehicle or by donating to the
“Give Wildlife a Chance” State Income Tax Checkoff. Sales of the bald
eagle/American flag license plate are the primary source of funding for
the WRD Nongame Wildlife and Natural Heritage Section.
