While alligators are often associated with southern states, their presence in Tennessee is a documented and increasingly noticeable reality. This article provides factual information on where these animals are found, why they are appearing, and how to safely coexist with them.
Alligators in Tennessee
Alligators are present in Tennessee, with confirmed sightings primarily concentrated in the southwestern counties. The Tennessee Wildlife Resources Agency (TWRA) has documented their presence in areas such as Shelby, Tipton, Lauderdale, and Fayette counties. Sightings have also been reported in Hardin County, and a seven-foot alligator was videotaped by the TWRA in Fayette County’s Wolf River Wildlife Management Area. While not historically abundant, their current presence marks a natural expansion of their range.
The first confirmed sighting of a wild alligator in Tennessee occurred in 2010 in Reelfoot Lake in Obion County. Since then, more sightings have been recorded, particularly near the Mississippi River and its connected waterways, which facilitate their movement from states like Mississippi and Louisiana. Alligators are considered a protected species in Tennessee, and the TWRA has not stocked or released them into the state.
Why Alligators Are Appearing in Tennessee
The increasing appearance of alligators in Tennessee is due to natural range expansion and environmental factors. As alligator populations thrive in neighboring southern states like Mississippi, Alabama, and Arkansas, younger alligators naturally disperse in search of new territories. This natural dispersal leads some individuals to venture into Tennessee’s suitable aquatic environments.
Climate change also plays a role in this northward expansion, as warmer winters make Tennessee’s environments more hospitable for these cold-blooded reptiles. Alligators are ectothermic, meaning their body temperature relies on external heat sources, and milder temperatures allow them to survive further north than they could historically. Tennessee’s wetlands, rivers, and swamps, particularly in the southern regions, offer suitable habitats with ample food sources, supporting their presence.
Coexisting with Alligators
Living in areas where alligators are present requires adherence to safety guidelines to ensure safety. Maintain a safe distance from alligators; approaching, interacting with, or feeding them is prohibited and dangerous. Alligators that are fed by humans can lose their natural fear of people, increasing the risk of negative encounters.
Keeping pets on leashes near water bodies and avoiding swimming or wading in areas known to harbor alligators are also crucial. Alligators are opportunistic feeders, and pets can be mistaken for prey. If an alligator is sighted and appears to be a threat to human safety or livestock, it should be reported to the Tennessee Wildlife Resources Agency (TWRA). Alligators are a Class 1 wildlife species in Tennessee, meaning they are considered inherently dangerous to people, and their possession or release is illegal.
