Habitat & Range

Hispid cotton rats are found in many regions in North and South America. In the U.S. these cotton rats have been distributed as far west to Nebraska and as far east as Virginia. The hispid cotton rats are commonly seen in dense grassy fields or open fields.

Food Web & Energy Flow

Hispid cotton rats mostly eat stems, leaves, roots, seeds, and sometimes young birds or insects. They are secondary consumers and omnivores.

Relationship to Fire

Hispid cotton rats are nocturnal which means they are active at night. During the day, these cotton rats use dense vegetation for protection and shelter. They need frequent fires in the area to keep the understory growing. Since most of the food they consume depend on a healthy forest floor, frequent fires are important to them. The fires can help clear space on the forest floor which can provide more sunlight to the plants and more nutrients to the soil.

Fire Suppression

Many people think of fires in the forest as bad, so they work hard to prevent or suppress them. But longleaf forests NEED regular fire to support habitat for the species that live there!

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.
