Designation of critical habitat is required for species listed under the Endangered Species Act.
NOAA Fisheries is designating critical habitat in U.S. waters off the coast of Alaska for Arctic ringed seals and the Beringia distinct population segment (DPS) of bearded seals. Both species are listed as threatened under the Endangered Species Act (ESA).
The ESA requires that NOAA Fisheries designate critical habitat for listed species in areas within the jurisdiction of the United States. Critical habitat identifies geographic areas that contain features essential to the conservation of a listed species.
For each species, the critical habitat area includes marine waters of the northern Bering, Chukchi, and Beaufort seas. The critical habitat boundaries differ between the two species, reflecting differences in where the essential habitat features for each species are found. For each of the designations, the geographic extent of the critical habitat is discussed in detail in the final rule and is depicted on a map.
