Dangerous Wildlife in Tennessee (9 Things)

The state of Tennessee has an area of 42,181 square miles and shares a border with 8 other states, more than any other state. The 8 states that border Tennessee are Kentucky, Virginia, North Carolina, Georgia, Alabama, Mississippi, Arkansas, and Missouri. From the Great Smoky Mountains in the east to the Mississippi River to the west, you’ll find a wide variety of wildlife in Tennessee. In this article we’re going to talk about some of the more dangerous wildlife in Tennessee.

But first, let’s define wildlife in simple terms.

What is wildlife?

The term wildlife originally referred to undomesticated animals. A more modern definition of wildlife includes all organisms that live in their natural habitats, away from humans. Both plants and animals. 

Wildlife is found in all ecosystems on the planet. Some examples of ecosystems are deserts, forests, plains, grasslands, and rainforests. Each one will have certain types of animals and plants that thrive under those specific conditions.

Dangerous wildlife in Tennessee

Here’s a short list of dangerous wildlife found in Tennessee that I put together. Not all of them will kill you, but dangerous in their own ways.

1. Copperheads

Copperheads are probably the most common, and commonly seen venomous snakes in the state of Tennessee. It’s smart to watch out for them when hiking in the woods, and just generally be aware of their presence in nature. They are not aggressive and will mind their own business if we mind ours.

Copperheads have hemotoxic venom. This means that the type of venom copperheads produce creates tissue damage around the area of bite

2. Rattlesnakes

The pygmy rattlesnake and the timber rattlesnake are the 2 types of rattlesnakes that can be found in Tennessee. The timber rattlesnake is more common and found across the state, they can grow to 5 feet in length. Timber rattlesnakes are likely the most dangerous venomous snake in Tennessee out of the 4 found in the state.

The pygmy rattlesnake is the other type of rattlesnake found in Tennessee. These snakes are smaller and only reach about 2 feet as adults. Pygmy rattlesnakes aren’t very common in Tennessee, and not found at all in east Tennessee. A bite from a pygmy rattlesnake may be extremely painful but probably wouldn’t be life threatening.

3. Black bears

The black bear is the largest apex predator we have in Tennessee. The only other large predator in Tennessee is the mountain lion, and they are considered quite rare in the state. There are an estimated 7,000 black bears in Tennessee today with a healthy, growing population.

Black bears will usually avoid human contact, however you never can be too careful. A mother protecting her cubs or a starving male that’s hungry enough to take what he wants… a person is no match for a bear. Some of the larger males can reach 700-800 lbs at adulthood. Black bears are most common in eastern Tennessee near the Smoky Mountains.

4. Black widows

If you live in the United States then you’ve heard of this spider, the black widow. They are the most venomous spider in the U.S. and one of only 3 venomous spiders found in the United States. In the year 2013, a total of 1866 black widow bites were reported. Of those bites, none were fatal.

Having said that, black widows are not to be trifled with. A black widow bit can cause severe pain, swelling around the bite, nausea, sweating, cramping, and other symptoms. If you’re bitten by a black widow, you should seek medical attention.

5. Brown recluses

Brown recluse spiders are common in southeastern areas of the continental United States, including most of Tennessee. Brown recluse venom is said to be more powerful than that of a rattlesnake, but the amount of venom released by the spider is so much less it makes them less dangerous.

You can recognize this spider by their brown color and violin-shaped marking on their cephalothorax. They may enter homes, especially in the fall as the weather is cooling down and they are looking warmth just like all the other critters.

6. Skunks

Their spray is incredibly powerful. The smell of it can linger for days with some instances reporting people smelled even after weeks. This spray is also extremely irritating and can cause temporary blindness if you’re unfortunate enough to get sprayed. Skunks typically avoid human contact but they are very quick to spray if they feel threatened.

Skunk spray won’t kill you, or even seriously harm you, but they can cause some extreme discomfort and even difficulty breathing. In addition, someone who’s been sprayed by a skunk may experience nausea and vomiting as well as respiratory problems. Then there’s always the chance of catching rabies from a skunk, they’re one of the primary carriers of it in the United States.

7. Ticks

It’s pretty well known that ticks are bad news. Ticks are found throughout the country in every state, including Tennessee. Most of the time a tick bite isn’t a huge deal, but some ticks carry diseases like Rocky Mountain spotted fever and Lyme disease that they can pass on to humans.

The effects of these diseases can last months or even years. It’s believed that 10 – 20 percent of tick bites experience lasting symptoms like arthritis, cognitive difficulties, chronic fatigue, or sleep disturbances. All that makes this little animal very dangerous to humans.

8. Poison ivy

It’s estimated that approximately 75% of people have an allergic reaction of some type when exposed to this plant. The remaining 25% of people have no reaction, I fall in the latter group. For those that are allergic to poison ivy, the symptoms that come with merely touching this plant can range from a mild rash to quite severe.

The rash poison ivy causes is an allergic reaction to something called urushiol, an oily resin on the outer skin of the plant. Aside from an itchy rash, poison ivy can cause swelling, headache, fever, or an infection. If the rash is not getting better within 2 weeks it’s recommended you see a doctor.

9. Poison hemlock

Hemlock is a poisonous plant that grows throughout the country, including Tennessee. Merely touching this plant may cause an adverse reaction to some people’s skin, but ingesting it can kill you. It’s believed that Socrates ate this plant in 399 BC and that’s what killed him.

Today the poison hemlock is used by doctors and scientists to create medicine for a host of ailments. As long as you don’t eat any strange plants you should be fine, but ingesting this one can cause respiratory failure and kill you in a few hours if untreated.


Conclusion

These are some of the more notable dangerous wildlife, both plants and animals, to watch out for in Tennessee. There are probably dozens more types of plants and animals to watch out for. Like wasps, bees, and other stinging insects!
