Status and Occurrence of Parakeet Auklet (Aethia Psittacula) in British Columbia
Status and Occurrence of Parakeet Auklet (Aethia psittacula) in British Columbia. By Rick Toochin and Louis Haviland. Introduction and Distribution The Parakeet Auklet (Aethia psittacula) is a small species of auklet found breeding in the Beringia region of Alaska and Russia (Gaston and Jones 1998). This species has an Alaskan population estimated at 1 million birds (Gaston and Jones 1998). There is also a Russian population, but the exact population total is not known, due to a lack of population inventory work, but it is estimated to number about 400,000 birds with the vast majority, about 300,000 birds, found in the Sea of Okhotsk (Gaston and Jones 1998). The Parakeet Auklet has breeding colonies that are found on rocky mainland points and islands in the Gulf of Alaska (Jones et al. 2001). These sites include: Shumagin Island, Semidi Isand, Chirikof Island near Kodiak, locally in Kenai Peninsula and southeastern Alaska with small numbers south to St. Lazaria, Hazy and Forrester Island; and in the Aleutian Islands west to Buldir and Agattu Island; and in the Bering Sea at Little Diomede, St. Lawrence Island, King Island, St. Matthew Island, Pribilof Island and Nunivak Island (Sowls et al. 1978). The Parakeet Auklet also breeds in Russia in the Kurile Island chain with colonies on Chirinkontan, Lovushki, Raikoke, Matua, Yankicha, Simushir, Brat Chirpoev, Urup, and Iturup Island (Jones et al. 2001, Brazil 2009). They are also breeding on islands in the Sea of Okhotsk with colonies on Sakhalin, Tyuleniy, Iona, Talan, and Yamskyie Island (Jones et al. 2001, Brazil 2009). The Parakeet Auklet is also found breeding on Commander Island, and northwards locally along coast of the Kamchatka Peninsula, on Karaginski Island, Cape Navarin, and on Chukotka Peninsula (Konyukhov 1989, Kondratyev et al. -
Southcentral Alaska Stock
Revised: April 2014 NORTHERN SEA OTTER (Enhydra lutris kenyoni): Southcentral Alaska Stock STOCK DEFINITION AND GEOGRAPHIC RANGE Sea otters occur in nearshore coastal waters of the U.S. along the North Pacific Rim from the Aleutian Islands to California. The species is most commonly observed within the 40-meter (approximately 12.2 feet [ft]) depth contour because the animals require frequent access to benthic foraging habitat in subtidal and intertidal zones (Reidman and Estes 1990). Sea otters are not migratory and generally do not disperse over long distances, although movements of tens of kilometers (km) (tens of miles [mi]) are common (Garshelis and Garshelis 1984). Annual home range sizes of adult sea otters are relatively small, with male territories ranging from 4 to 11 square kilometers (km2) (approximately 10.5 to 28.5 square miles[mi2]) and adult female home ranges from a few to 24 km2 (approximately 62 mi2) (Garshelis and Garshelis 1984; Ralls et al. 1988; Jameson 1989). Due to their benthic foraging, sea otter distribution is largely limited by their ability to dive to the sea floor (Bodkin et al. 2004). 1 Figure 1. Approximate distribution and stock boundaries of northern sea otters in Alaska waters (shaded area). The spatial scale at which sea otter populations are managed remains an important, although largely unexplored issue (Bodkin and Ballachey 2010) deserving further study. Bodkin and Ballachey (2010) used models of sea otter mortality to show that range-wide reductions and extirpations during the commercial fur trade of the 18th and 19th centuries occurred not simply because of excessive harvest, but because the harvest was not allocated proportional to the abundance and distribution of sea otters. -

Historical Timeline for Alaska Maritime National Wildlife Refuge
Historical Timeline Alaska Maritime National Wildlife Refuge Much of the refuge has been protected as a national wildlife refuge for over a century, and we recognize that refuge lands are the ancestral homelands of Alaska Native people. Development of sophisticated tools and the abundance of coastal and marine wildlife have made it possible for people to thrive here for thousands of years. So many facets of Alaska’s history happened on the lands and waters of the Alaska Maritime Refuge that the Refuge seems like a time-capsule story of the state and the conservation of island wildlife: • Pre 1800s – The first people come to the islands, the Russian voyages of discovery, the beginnings of the fur trade, first rats and fox introduced to islands, Steller sea cow goes extinct. • 1800s – Whaling, America buys Alaska, growth of the fox fur industry, beginnings of the refuge. • 1900 to 1945 – Wildlife Refuge System is born and more land put in the refuge, wildlife protection increases through treaties and legislation, World War II rolls over the refuge, rats and foxes spread to more islands. The Aleutian Islands WWII National Monument designation recognizes some of these significant events and places. • 1945 to the present – Cold War bases built on refuge, nuclear bombs on Amchitka, refuge expands and protections increase, Aleutian goose brought back from near extinction, marine mammals in trouble. Refuge History - Pre - 1800 A World without People Volcanoes push up from the sea. Ocean levels fluctuate. Animals arrive and adapt to dynamic marine conditions as they find niches along the forming continent’s miles of coastline. -

Alaska OCS Socioeconomic Studies Program
. i, WUOE (ixlw Technical Report Number 54 Volume 1 -, Alaska OCS Socioeconomic Studies Program Sponsor: Bureau of Land Management — Alaska Outer ‘ Bering–Normn Pwdeum Development Scenarios Sociocultural Syst~ms Analysis The United States Department of the Interior was designated by the Outer Continental Shelf (OCS) Lands Act of 1953 to carry out the majority of the Act’s provisions for administering the mineral leasing and develop- ment of offshore areas of the United States under federal jurisdiction. Within the Department, the Bureau of Land Management (ELM) has the responsibility to meet requirements of the National Environmental Policy Act of 1969 (NEPA) as well as other legislation and regulations dealing with the effects of offshore development. In Alaska, unique cultural differences and climatic conditions create a need for developing addi- tional socioeconomic and environmental information to improve OCS deci- sion making at all governmental levels. In fulfillment of its federal responsibilities and with an awareness of these additional information needs, the BLM has initiated several investigative programs, one of which is the Alaska OCS Socioeconomic Studies Program (SESP). The Alaska OCS Socioeconomic Studies Program is a multi-year research effort which attempts to predict and evaluate the effects of Alaska OCS Petroleum Development upon the physical, social, and economic environ- ments within the state. The overall methodology is divided into three broad research components. The first component identifies an alterna- tive set of assumptions regarding the location, the nature, and the timing of future petroleum events and related activities. In this component, the program takes into account the particular needs of the petroleum industry and projects the human, technological, economic, and environmental offshore and onshore development requirements of the regional petroleum industry. -
