Gopher tortoises are considered a keystone species of the longleaf pine ecosystem, with many species depending on them for survival or benefitting from their presence. More than 360 species of mammals, birds, reptiles, amphibians, and invertebrates are known to spend all or a portion of their lives in either active or abandoned gopher tortoise burrows. Some species are completely or largely dependent on these burrows for survival.
As might be expected, gopher tortoise populations have had a similar fate as has the species habitat. The extent of the longleaf pine ecosystem in the southeastern United States has been reduced to less than three million acres, a small fraction of its former range. The rolling savannah-like world of the southeastern coastal plain is, for the most part, gone, and gopher tortoise populations are estimated to have declined by at least 80% in the last hundred years.

Gopher tortoises are currently federally listed as threatened west of the Tombigbee and Mobile Rivers and eastern populations are being considered for federal listing as well. Gopher tortoises are considered a species of High Conservation Concern in Alabama and are fully protected by law. They are also listed as threatened or endangered at the state level in other parts of their range in South Carolina, Georgia, Florida, Mississippi, and Louisiana.
While recent trends have not been good for either the longleaf pine ecosystem or the gopher tortoise, the tide may be turning. The Longleaf Restoration Initiative is a joint effort by numerous government and non-government agencies having the shared goal of seeing longleaf pine and its associated ecosystem restored on suitable sites across its historical range. To this end, the United States Forest Service has made restoration of the mature longleaf pine ecosystem a priority on its lands in the southeastern region. In time, through reforestation of suitable sites to longleaf pine and the reestablishment of a more natural burning regime within existing stands, considerable acreage of mature or maturing longleaf pine habitat may be restored. Also encouraging is the fact that numerous landowner cost share programs, both state and federal, are prioritizing planting of longleaf pine on sites best suited to them and using prescribed fire to maintain habitat. The Alabama Forestry Commission, the Alabama Department of Conservation and Natural Resources, and the Natural Resource Conservation Service are leaders in this effort. Many non-government agencies such as the Longleaf Alliance are working through research, education, and commercial activities, to promote retention and restoration of longleaf pine on productive sites throughout the southeast.
Currently, a State Wildlife Grant is funding a study of the distribution, abundance, and health status of gopher tortoises in Alabama. Data will be collected over a four year period to establish the status of gopher tortoises on both public and private lands in our state. An effort will be made to assess the number of stable and declining gopher tortoise populations that are present on public and private lands. Further, populations will be evaluated as to the presence or absence of an upper respiratory tract disease and how the disease affects gopher tortoises under a variety of circumstances and stress factors. Efforts will be made to engage and inform the public regarding gopher tortoises and their management.
Through the cooperation of many government agencies, private entities, and conservation minded individuals the future of the gopher tortoise and the ecosystem of which it is a part will improve dramatically.
