The U.S. National Marine Fisheries Service has completed its review of the status of eastern North Pacific harbor seals (Phoca vitulina richardii) in Iliamna Lake, Alaska. NMFS’ review was in response to a petition to list these seals as threatened or endangered under the Endangered Species Act. Based on the best scientific and commercial information available, we conclude that the seals in Iliamna Lake do not constitute a species, subspecies, or distinct population segment under the ESA. As a result, NMFS has concluded that listing the harbor seals in Iliamna Lake, Alaska is not warranted.
