Habitat & Range

The southern hognose snakes were historically found in the southern parts of the United States namely from North Carolina to Florida. As of today, they are only found in Georgia, South Carolina, North Carolina, and Florida. These hognose snakes are often found in sandhills, pine flatwoods, and coastal plain habitats. This species prefer sandy soils and grassy understories. They live underground and come out only to feed.

Food Web & Energy Flow

The largest portion of the southern hognose snakes diet is consuming frogs and toads. Sometimes they may eat small lizards when they are easily spotted. In the back of their mouth they have enlarged teeth called rear fangs that are used to puncture inflated toads. They use mild venom to kill their prey instead of constricting.

Relationship to Fire

The southern hognose snakes use the grassy forest floor to find the toads and frogs they like to eat. When fires are frequent, more vegetation is available which can increase the number of frogs and toads. The population of these hognose snakes can decline faster if fire suppression continues.

Conservation Status

The longleaf pine flatwoods has been experiencing fire suppression and habitat loss due to agricultural land uses. These factors have impacted the hognose snake habitat, causing them to become Imperiled.

Fear

Many people are afraid of snakes and kill them out of fear or concern for safety. The good news is that these snakes are not venomous and would rather not deal with humans.

Land Use Conversion

Longleaf forests and the habitat it supports is being cleared or converted to use the land for other uses like houses, roads, agriculture, and even to grow different types of trees to sell.
