Description: Critical habitat for the Western DPS of Steller sea lions includes:(a) Alaska rookeries, haulouts, and associated areas. In Alaska, all major Steller sea lion rookeries identified in Table 1 and major haulouts identified in Table 2 and associated terrestrial, air, and aquatic zones. Critical habitat includes a terrestrial zone that extends 3,000 feet (0.9 km) landward from the baseline or base point of each major rookery and major haulout in Alaska. Critical habitat includes an air zone that extends 3,000 feet (0.9 km) above the terrestrial zone of each major rookery and major haulout in Alaska, measured vertically from sea level. Critical habitat includes an aquatic zone that extends 3,000 feet (0.9 km) seaward in State and Federally managed waters from the baseline or basepoint of each major rookery and major haulout in Alaska that is east of 144° W. longitude. Critical habitat includes an aquatic zone that extends 20 nm (37 km) seaward in State and Federally managed waters from the baseline or basepoint of each major rookery and major haulout in Alaska that is west of 144° W. longitude.(b) California and Oregon rookeries and associated areas. In California and Oregon, all major Steller sea lion rookeries identified in Table 1 and associated air and aquatic zones. Critical habitat includes an air zone that extends 3,000 feet (0.9 km) above areas historically occupied by sea lions at each major rookery in California and Oregon, measured vertically from sea level. Critical habitat includes an aquatic zone that extends 3,000 feet (0.9 km) seaward in State and Federally managed waters from the baseline or basepoint of each major rookery in California and Oregon.(c) Three special aquatic foraging areas in Alaska. Three special aquatic foraging areas in Alaska, including the Shelikof Strait area, the Bogoslof area, and the Seguam Pass area.ESA timeline:Steller sea lions were originally listed (55 FR 49204, November 26, 1990) under the ESA throughout their range and critcal habitat was designated in 1993 (58 FR 45269, August 27, 1993). The critical habitat designation was amended (59 FR 30715, June 15, 1994) to correct data errors in Table 2 (Major Steller Sea Lion Haulout sites in Alaska) to Part 226 in the CFR.Steller sea lions were reclassified and listed as 2 DPSs: the Western DPS and Eastern DPS (62 FR 24345, May 5, 1997).The Eastern DPS of Steller sea lions was delisted (78 FR 66140, November 4, 2013). In the delisting final rule, NMFS clarified that the 1993 critical habitat designation remains in effect for the Western DPS of Steller sea lions.
