Timber Rattlesnakes Are Still Found Near Nashville

Most Nashville-area homeowners expect to deal with copperheads. Fewer expect to find a timber rattlesnake in the backyard — but it happens more often than people realize, especially in the wooded corridors that ring the metro area.

Timber rattlesnakes (Crotalus horridus) are the largest venomous snake in Tennessee and one of the most medically significant. They're also a protected species under Tennessee state law, which means you cannot legally kill one. If you find a timber rattlesnake on your property, your only legal option is professional removal.

Here's where they're still turning up in the Nashville suburbs — and what you need to know.

Timber rattlesnakes were once common throughout Middle Tennessee. Development pushed them out of most urban areas, but they've held on in the forested ridges, creek hollows, and preserved green space that still exist throughout the Nashville metro.

They're not rare — they're just secretive. Timber rattlesnakes are ambush predators that spend most of their time motionless, waiting for prey. A large adult can sit in the same spot for days without moving. That's why encounters often come as a surprise: you nearly step on one before you see it.

They're also long-lived snakes with low reproductive rates, which makes them slow to recover from population losses. Tennessee's protected status reflects that reality.

Franklin sees more timber rattlesnake activity than most residents expect. The wooded hillsides along the Harpeth River corridor, the undeveloped lots in newer subdivisions pushing into former farmland, and the forested edges of Williamson County's rural areas all provide suitable habitat.

Encounters most often happen along wooded lot lines, near creek banks, and in areas where suburban development meets intact forest. New construction that disturbs established habitat can push snakes into adjacent yards.

Brentwood's large wooded lots and proximity to forested ridges make it one of the more likely spots in the Nashville suburbs for a timber rattlesnake encounter. The species favors mature hardwood forest with rocky outcrops — exactly the kind of terrain found in the more established, heavily wooded neighborhoods in the eastern and southern parts of the city.

Reports of timber rattlesnakes in Brentwood tend to cluster near the wooded greenways and undeveloped parcels that remain throughout the city.

The forested areas around Old Hickory Lake and the rural portions of Sumner County provide good timber rattlesnake habitat. Hendersonville residents near wooded lake coves or properties backing up to undeveloped forest should be aware that the species is present in the area.

Sumner County's mix of suburban development and intact rural land creates the kind of edge habitat where timber rattlesnakes are most likely to be encountered — not deep in the woods, but at the transition zone between developed and undeveloped land.

Gallatin sits in the heart of Sumner County, and the surrounding rural and semi-rural areas support timber rattlesnake populations. Encounters in Gallatin proper are less common than in more heavily wooded areas, but properties on the outskirts of town — particularly those near creek drainages or wooded ridges — are not immune.

Murfreesboro's rapid growth has pushed development into areas that were previously undisturbed habitat. The forested areas along the Stones River and its tributaries, as well as the rural portions of Rutherford County, still support timber rattlesnakes.

As development continues to expand outward from Murfreesboro, encounters at the suburban fringe are likely to increase. Properties near the Stones River Greenway or backing up to undeveloped woodland are the most likely encounter zones.

Timber rattlesnakes are heavy-bodied snakes that can reach four to five feet in length. Key identification features:

Rattle: The most obvious identifier. Even young timber rattlesnakes have a small button rattle. You may hear the rattle before you see the snake.

Color phases: Timber rattlesnakes in Tennessee occur in two color phases. The yellow phase has a yellowish or tan background with dark brown or black chevron-shaped crossbands. The dark phase is nearly all black, with the chevron pattern still visible on close inspection. Both phases are found in Middle Tennessee.

Head shape: Broad, triangular head that is distinctly wider than the neck — a characteristic of all pit vipers.

Chevron banding: The crossbands are chevron-shaped (pointing forward toward the head), not simple saddle-shaped blotches. This distinguishes them from copperheads, which have hourglass-shaped banding.

Body mass: Timber rattlesnakes are significantly heavier-bodied than most non-venomous snakes of similar length. A large adult is a substantial animal.

Do not approach it. Timber rattlesnakes are not aggressive, but they will defend themselves if threatened. Give the snake plenty of space — at least six feet.

Do not attempt to kill it. Timber rattlesnakes are protected under Tennessee state law. Killing one is illegal and can result in fines. Beyond the legal issue, the majority of venomous snakebites occur when people attempt to handle or kill snakes.

Keep children and pets away. Clear the area and keep everyone at a safe distance until a professional can respond.

Call a professional. Nashville Snake Removal handles timber rattlesnake removal throughout the Nashville metro area, including Franklin, Brentwood, Hendersonville, Gallatin, and Murfreesboro. We respond same-day, safely capture and relocate the snake, and can advise on habitat modifications to reduce future activity.

Tennessee classifies the timber rattlesnake as a Species of Special Concern. It is illegal to kill, harm, harass, or possess a timber rattlesnake without a permit. This protection exists because the species has experienced significant population declines due to habitat loss, persecution, and collection.

Professional wildlife removal operators are licensed to handle and relocate timber rattlesnakes. If you find one on your property, the right call — legally and practically — is to contact a licensed professional.

Timber rattlesnakes haven't disappeared from the Nashville area. They've retreated to the wooded edges and rural corridors that remain, and as suburban development continues to push into those areas, encounters will continue.
