Animal Welfare Act
The title of largest animal in the Park
goes to the Elk, which were reintroduced to the Cataloochee area of the Park in 2001 in an effort to create a habitat that more closely resembles one before humans over hunted and eliminated certain species from the area. River Otters have been reintroduced as well. Bobcats are the only member of the cat family documented in the Park,
although there have been reports of mountain lion sightings by visitors. White tail deer are probably the most commonly seen mammal, especially in the Cades Cove section of the Park. There are only two species of poisonous snake in Great Smoky Mountains National Park: Timber Rattler and Copperhead. There are a number of other common snakes, including the Northern Water Snake (which looks like a cottonmouth, but cottonmouth's are not found in the Park), Corn Snake, Garter Snake, and umerous black or brown snakes that eat rodents.
