Arkansas boasts a rich biodiversity, and its snake population is no exception. While venomous snakes like copperheads and cottonmouths exist, a significant portion of Arkansas's snake species are entirely harmless to humans. Understanding these non-venomous snakes is crucial for appreciating the state's natural heritage and fostering responsible coexistence.

Identifying Arkansas's Non-Venomous Snakes

Identifying snakes correctly is paramount, especially to avoid unnecessary fear or harm. While this guide provides helpful information, always approach snakes with caution and maintain a safe distance. If uncertain about a snake's identity, consult a herpetologist or wildlife expert.

Common Non-Venomous Snakes of Arkansas

Several non-venomous snake species thrive in Arkansas's diverse habitats. Here are some of the most commonly encountered:

Eastern Garter Snake (Thamnophis sirtalis): These are arguably the most common snakes in Arkansas. They're easily recognizable by their three longitudinal stripes—one on the back and one on each side. They're highly variable in color, ranging from brown to olive green to even black. They primarily feed on amphibians, fish, and worms.
Black Rat Snake (Pantherophis obsoletus): Often mistaken for venomous snakes due to their size, black rat snakes are completely harmless. They're typically dark-colored, though juveniles may exhibit some pattern. They're excellent climbers and are often found near buildings. They feed mainly on rodents.
Corn Snake (Pantherophis guttatus): Known for their beautiful patterns, corn snakes are popular as pets. In the wild, they're found in a variety of habitats and feed on small mammals and birds. They are typically reddish-brown with blotches.
Great Plains Rat Snake (Pantherophis emoryi): Similar to the black rat snake, but generally more slender and lighter in color, often displaying brown or reddish patterns. These snakes are strong climbers and excel at hunting rodents in agricultural fields and forests.
Brown Snake (Storeria dekayi): These small, secretive snakes are often overlooked. They are uniformly brown or gray-brown and have a very smooth, shiny scale texture. They feed mostly on earthworms and slugs.

Key Identification Features:

Non-Venomous Characteristics:

Round pupils: Unlike the elliptical pupils of most venomous snakes.
Lack of heat-sensing pits: Venomous pit vipers have these pits located between their eyes and nostrils.
Usually smaller fangs: While some non-venomous snakes have fangs, they lack the large, retractable fangs of venomous species.
Smooth scales: Many (but not all) non-venomous snakes have smoother scales than venomous ones.

Remember: These are guidelines, not definitive rules. Definitive identification sometimes requires close examination and expertise.

Habitats of Non-Venomous Snakes in Arkansas

Arkansas's varied landscape supports a range of snake habitats. From forests and fields to wetlands and urban areas, non-venomous snakes occupy diverse niches.

Forests: Many species, including rat snakes and corn snakes, utilize forests for shelter and hunting grounds. Fallen logs, rock piles, and hollow trees provide ideal hiding places.
Fields and grasslands: Garter snakes and brown snakes often inhabit these open areas, using the cover provided by vegetation and burrows.
Wetlands and waterways: Garter snakes are frequently found near water sources, where they prey on aquatic organisms.
Urban areas: Rat snakes, in particular, are adept at adapting to human-altered environments, often seeking shelter in buildings and outbuildings.

Behavior and Diet of Non-Venomous Snakes

Non-venomous snakes exhibit a variety of behaviors depending on their species and environment.

Diurnal vs. Nocturnal: Some snakes are active during the day (diurnal), while others are more active at night (nocturnal).
Diet: Their diets consist primarily of small animals like rodents, amphibians, insects, eggs, and other snakes.

The Importance of Non-Venomous Snakes in the Ecosystem

Non-venomous snakes play a vital role in maintaining ecological balance within Arkansas's ecosystems. They act as important predators, controlling populations of rodents, insects, and other small animals. This helps prevent overpopulation and protects crops and other resources.

Coexisting with Non-Venomous Snakes

While generally harmless, it's essential to approach snakes with respect and caution. Avoid handling snakes unless you are a trained herpetologist. If you find a snake in your yard, gently encourage it to move on by providing a safe escape route, such as a path to nearby vegetation. Never attempt to kill a snake, as they are beneficial to the environment.

Conclusion

The non-venomous snakes of Arkansas contribute significantly to the state’s biodiversity. By understanding their identification, habitats, and ecological roles, we can foster a respectful and safe coexistence with these fascinating creatures. Remember, responsible observation and appreciation are key to preserving these important parts of Arkansas's natural heritage.
