Few snakes command attention quite like the Eastern Diamondback Rattlesnake (Crotalus adamanteus). Georgia’s largest rattlesnake (and the largest venomous snake in North America!) is recognizable by the distinctive dark diamonds bordered in yellow or cream along its back. Native to the Coastal Plain, Eastern Diamondbacks use a variety of open, fire-maintained habitats, including pine flatwoods, sandhills, coastal forests and other early-successional landscapes.
Our Stewardship Director, Laura Hall, encountered this beautiful creature while visiting an ORLT conservation easement in Toombs County. This is a great reminder that protecting intact habitat can benefit even species that are often misunderstood. Eastern Diamondbacks are listed as a Species of Greatest Conservation Need (SGCN) in Georgia’s 2025 State Wildlife Action Plan and are considered a species of moderate conservation concern.
While a close encounter with a rattlesnake can be startling, the safest response is also the simplest: give it space and leave it alone. Never attempt to handle, harass or kill a snake, and if you encounter one while hiking, calmly move away and give it a wide berth. Pay attention to where you place your hands and feet when walking through dense vegetation, rock piles or other areas where wildlife may be sheltering, make your presence known when moving through thick cover. If you need to identify a snake, do so from a safe distance rather than approaching it for a closer look.
The state of Georgia is home to 47 native snake species, only seven of which are venomous. Most snakes people encounter are not venomous. Even if a clearly identified venomous snake is creating an immediate danger to people or pets, do not try to remove it yourself; seek assistance from a qualified wildlife-removal professional.
Eastern Diamondbacks play an important role in healthy ecosystems. As predators, snakes help regulate populations of rodents and other small animals, while also serving as prey for other wildlife. Their presence is an important part of a functioning food web.
Unfortunately, Eastern Diamondbacks have declined in Georgia due in part to habitat loss and human-caused mortality, with remaining populations mostly concentrated in suitable areas of the southern part of the state, including portions of the Altamaha River drainage and coastal region. Conservation of large, connected landscapes, and the natural habitat-management practices that maintain them is essential to their future.
Protecting land through conservation easements helps safeguard these habitats while giving wildlife the space they need to persist. Encounters like Laura’s are a reminder that conservation is about protecting the full diversity of life on the landscape, including species that may traditionally inspire a little more fear than affection.
