The Maine Department of Inland
Fisheries and Wildlife holds management responsibility
for inland fish and wildlife listed under MESA, and
shares responsibility with the U.S. Fish and
Wildlife Service [USFWS] for inland fish
and wildlife listed under ESA.
The Maine Endangered Species Act applies only to animals - plants are not included in the legislation. The Maine Natural Areas Program maintains an "official" list of rare and endangered plants in Maine.
There are currently 22 inland fish and
wildlife species listed as Endangered and 23 listed as
Threatened under Maine's Endangered Species Act [MESA],
some of which are also listed under the U.S. Endangered
Species Act [ESA].
