According to the federal agency, the black pinesnake is found only in Mobile, Washington and Clarke counties in Alabama, and 11 Mississippi counties, including Jackson and George. It has not been seen in Louisiana in more than 30 years.

If deemed threatened under the Endangered Species Act, the government would impose certain restrictions on activities like the use of herbicides, controlled burns and some timber activities in the affected habitat areas.

"The black pinesnake is an important part of the longleaf pine ecosystem in southern Alabama and Mississippi," Fish & Wildlife Southeast Regional Director Cindy Dohner said in a prepared statement. "Conservation efforts for the black pinesnake align closely with efforts already ongoing in this ecosystem for other wildlife like the gopher tortoise, eastern indigo snake, dusky gopher frog and the red-cockaded woodpecker."
