(6) Assessing the socioeconomic costs and benefits of sea otter range expansion to anticipate and mitigate conflicts: The effects of sea otters on shellfish fisheries are well documented, but fine-scale information on sea otter distribution, population growth and future expansion is needed to support the adaptation of communities affected by expanding sea otter populations. The 2018 census of southern sea otters (Enhydra lutris nereis) was conducted from late April to mid-May along the mainland coast of central California and in April at San Nicolas Island in southern California.

Despite successful reintroduction efforts elsewhere in North America, the Oregon sea otter population remains locally extirpated and listed as endangered. The northern range was not calculated because of limitations in survey resources required to survey areas north of the range from the previous year (2018); however, the southern range expanded slightly by 0.5 kilometer, where a negligible trend in sea otter counts (0.55 percent growth per year) corresponded to the lack of meaningful population range expansion at the southern periphery.

Sea otters were locally extinct in British Columbian waters in Canada, until a plane containing a romp of otters arrived and set off a population boom – with unintended consequences.

The southern sea otter population has plateaued in recent years (Tinker and Hatfield, 2018) and natural range expansion is currently restricted by the distribution of kelp forests due to increased predation on otters in areas with low kelp cover (Moxley et al., 2019; Nicholson et al., 2018).

Sea otters in Alaska. Today’s otters are descended from about 400 animals (from the Aleutians) reintroduced to the region in the 1960’s. The scientists found that as the sea otter population more than doubled from 1980 to 2018, so did the size of the Dungeness crab catch per fishing … Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. Adult sea otters typically weigh between 14 and 45 kg (31 and 99 lb), making them the heaviest members of the weasel family, but among the smallest marine mammals.

In an interview with Anchorage Daily News in 2018, Jim Estes, an ecology professor and otter expert at the University of California, Santa Cruz said about the increasing population of sea otters in Southeast Alaska, “I think what we’re headed toward is a return to normality.” He was referring to returning to an ecosystem that includes sea otters. California Sea Otter (Enhydra lutris nereis) Census Results, Spring 2019 By Brian B. Hatfield, Julie L. Yee, Michael C. Kenner, and Joseph A.

The sea otter (Enhydra lutris) was nearly driven to extinction on the Pacific Coast in the 19th century due to intensive commercial hunting and the maritime fur trade. My aims for this analysis were to investigate any changes that occurred in the kelp forest ecosystem surrounding San Nicolas island during the length of the sea otter translocation program. According to the U.S. The sea otter population in Morro Bay is healthy even as the Central Coast has seen more otter deaths from shark bites.

Lower urchin density reduces grazing pressure on kelps, resulting in a more diverse nearshore ecosystem (Estes and Duggins 1995). More information: Roderick B. Gagne et al, Measures of effective population size in sea otters reveal special considerations for wide-ranging species, Evolutionary Applications (2018). Sea otters spend much of their lives in the water and can dive up to 330 feet when foraging for food, though most dives are much shallower. That’s how the director of the Monterey Otter Project describes it. The population declined to a uniformly low density in the archipelago, suggesting a common and geographically widespread cause.
