HABITAT DESCRIPTION:
The hellbender inhabits medium to larger, clear, fast-moving mountain streams in tributary watersheds of the Mississippi River (Wilson 1995). Most major river systems in the western North Carolina mountains have some streams that are occupied.

Typically, only streams in predominantly forested watersheds provide the cool, well oxygenated stream conditions required by hellbenders.

In the mountains, lengths of stream below 2500 ft. with numerous flat boulder and cobble-sized rocks for shelter are preferred (King 1939, Wilson 1995). Other large submerged objects, such as logs, and bank holes in or at water's edge may also be used for shelter.

NATURE SERVE GLOBAL HABITAT COMMENTS:

Rocky, clear creeks and rivers, usually where there are large shelter rocks. Usually avoids water warmer than 20 C. Males prepare nests beneath large flat rocks or submerged logs.

NATURE SERVE STATE HABITAT COMMENTS:

Under rocks in medium to large streams with cool, well oxygenated water. Able to inhabit bank holes where rocks not available.

 
MODELING DESCRIPTION:
Spatial Constraints:
Exclude all area outside of Mississippi drainages.
Exclude all drainages with less than 70% forest cover.
Exclude all water greater than 50 meters from land.
Exclude all land greater than 1 meter from open water.
Limited to elevation range: less than 2800 ft.
