"The contraction of the range of this population northward into the upper Inlet makes it far more vulnerable to catastrophic events with the potential to kill a significant fraction of the population. The population is not growing at 2% to 6% per year as had been anticipated since the cessation of unregulated hunting. The population is discrete and unique with respect to the species, and if it should fail to survive, it is highly unlikely that Cook Inlet would be repopulated with belugas. This would result in a permanent loss of a significant portion of their. The importance of seasonal anadromous fish runs in Cook Inlet to belugas is evident. The bulk of their annual nutrition is acquired during the summer months. Belugas in cook Inlet are unique to Alaska given their summer habitat is in close proximity to the largest urban area in the state. While the impact of disease and parasitism on this population has not been quantified, this population is at greater risk because of its small size and limited range such that a novel disease would spread easily through this population. The PVA shows a 26% probability of extinction in 100 years and 70% probability of extinction in 300 years (for the model assuming one predation mortality per year and a 5% annual probability of an unusual mortality event killing 20% of the population). It is likely that the Cook Inlet beluga population will continue to decline or go extinct over the next 300 years unless factors determining its growth and survival are altered in its favor"--P. xv.

The bulk of their annual nutrition is acquired during the summer months. The PVA shows a 26% probability of extinction in 100 years and 68% probability of extinction in 300 years (for the model assuming one predation mortality per year and a 5% annual probability of an unusual mortality event killing 20% of the population). It is likely that the Cook Inlet beluga population will continue to decline or go extinct over the next 300 years unless factors determining its growth and survival are altered in its favor."--Page xiii-xiv.

The Law Library presents the complete text of the Endangered And Threatened Species - Endangered Status for the Cook Inlet Beluga Whale (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition). Updated as of May 29, 2018 We, NMFS, issue a final determination to list a Distinct Population Segment (DPS) of the beluga whale, Delphinapterus leucas, found in Cook Inlet, Alaska, as endangered under the Endangered Species Act of 1973, as amended (ESA). Following completion of a Status Review of this DPS (the Cook Inlet beluga whale) under the ESA, we published a proposed rule to list this DPS as an endangered species on April 20, 2007. We subsequently extended the date for final determination on the proposed action by 6 months, until October 20, 2008, as provided for by the ESA.

The Law Library presents the complete text of the Endangered and Threatened Species - Designation of Critical Habitat for Cook Inlet Beluga Whale (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition). Updated as of May 29, 2018 We, the National Marine Fisheries Service (NMFS), designate critical habitat for the Cook Inlet beluga whale (Delphinapterus leucas) distinct population segment (DPS) under the Endangered Species Act (ESA). Two areas are designated, comprising 7,800 square kilometers (3,013 square miles) of marine habitat. In developing this final rule we considered public and peer review comments, as well as economic impacts and impacts to national security. We have decided in the final rule to exclude the Port of Anchorage (POA) in consideration of national security interest. Additionally, consistent with the proposed rule, portions of military lands were determined to be ineligible for designation as critical habitat. We solicited comments from the public on all aspects of the proposed rule, and conducted four public hearings on the action. Along with the proposed rule, we published a draft economic impacts analysis, entitled "Draft RIR/4(b)(2) Preparatory Assessment/IFRA for the Critical Habitat Designation of Cook Inlet Beluga Whale." This economic analysis has been completed to support the final designation. See "Final RIR/4(b)(2) Preparatory Assessment/FRFA for the Critical Habitat Designation of Cook Inlet Beluga Whale" for a discussion of these topics.
