State List of Endangered & Threatened Species

Endangered and Threatened inland fish and wildlife species in Maine are listed either under Maine's Endangered Species Act [MESA], the U.S. Endangered Species Act [ESA], or both. Species listed under MESA receive state protection; species listed under ESA receive federal protection; and species listed under both receive state and federal protection.

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.

Endangered and Threatened marine species are listed under Maine's Marine Endangered Species Act or ESA. The Maine Department of Marine Resources [MDMR] has responsibility for these species.

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].

Information about the status, life history, and conservation of each listed species is available in a fact sheet linked to the species name in the following lists. Fact sheets are available in PDF format.

Species listed through the Maine Department of Inland Fisheries and Wildlife under Title 12 § 12803. Marine species listed separately through the Maine Department of Marine Resources under Title 12 § 6975, and federally listed species not listed under Maine's Endangered Species Act, are not included in this list.
