23+iii pp. ABSTRACT Sea otter populations in Southeast Alaska, USA, have increased dramatically from just over 400 translocatedanimals inthelate 1960s to >8,000 by2003. The Commission expects to review updated stock assessment reports for the three northern sea otter stocks in 2018. Population. Exhibit 2: Southern Sea Otter Population Trends and Range by USFWS | Sep 25, 2018 | sea otters. The population declined to a uniformly low density in the archipelago, suggesting a common and geographically widespread cause. Tuesday, May 8, 2018. According to data just released by the California Department of Fish and Wildlife (CDFW) and U.S. Geological Survey (USGS), the three-year average population index this year dropped to 2,962, which is 166 sea otters fewer than the 2018 survey. 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.

California Sea Otter (Enhydra lutris nereis) Census Results, Spring 2019 By Brian B. Hatfield, Julie L. Yee, Michael C. Kenner, and Joseph A. Tomoleoni Abstract The 2019 census of southern sea otters (Enhydra lutris nereis), also known as California sea otters, was conducted from early May to early July along the mainland coast of On the cover: photo of Otter with sea urchins by Neil Fisher, otter group by Roy Toft; background by Joe Rocchio. The 3-year average of combined counts from the mainland range and San Nicolas Island was 3,128, a decrease of 58 sea otters from the previous year. The US supreme court declines a petition to reconsider a ruling by the ninth circuit court of appeal to reinstate a no otter zone that stretched from Point Conception south to the Mexican border.

(Photo courtesy of Matt Lichtenstein) Crabbers and dive fishermen returned to Alaska’s Board of Fish this month seeking changes to commercial fishing regulations in Southeast Alaska for crab and other shellfish impacted by a growing population of sea otters in the region. For more information on Southern sea otters, see the Commission’s 2012 annual report. Despite successful reintroduction efforts elsewhere in North America, the Oregon sea otter population remains locally extirpated and listed as endangered. Sea Otter Events and Resources. 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. For example, when sea otters are present in rocky habitats, they eat sea urchins and urchin density decreases as a result. and last updated 2018-09-26 22:38:16-04. 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). Today’s otters are descended from about 400 animals (from the Aleutians) reintroduced to the region in the 1960’s. Commission Letters. THE SEA OTTERS The sea otter (Enhydra lutris) is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. (Photo by patrickmoody / Flickr) Kayla Desroches/KMXT. SANTA CRUZ, Calif.— Southern sea otter numbers have declined off the coast of California since peaking in 2016, but the average population count remains above 3,090 for the third consecutive year. 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 … Southern sea otter distribution Current extent of established range 1 extralimital sea otter Area of map A OREGON NEVADA O N Figure 1. (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. Sato, C. L. 2018. Washington Department of Fish and Wildlife, Olympia, Washington. They often rest in coastal kelp forests, draping the kelp over their bodies to keep from drifting away. Unlike most marine mammals, the sea otter's primary form of … Southeast fishermen seek relief from expanding sea otter population January 15, 2018 by Joe Viechnicki, KFSK-Petersburg Sea otters raft up in the inside waters of Southeast Alaska in June 2014. Periodic Status Review for the Sea Otter in Washington. This report should be cited as Sato, C. L. 2018. Behavior. 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. 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. 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). Measures of effective population size in sea otters reveal special considerations for wide-ranging species Evol Appl. The southern sea otter population, which once numbered about 16,000 animals, is hovering around 3,000 today. That’s how the director of the Monterey Otter Project describes it. Sea otters raft up in the inside waters of Southeast Alaska in June 2014. 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. 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. Therefore, it seems unlikely to have an impact on Dungeness crab abundance in the near term. ... Should the northern and southern sea otter populations eventually merge, it would increase the genetic diversity of the CA population, potentially improving health and increasing adaptive potential. The population decline likely began in the mid-1980s and declined at a rate of 17.5%/year in the 1990s. Posted by Joe Viechnicki | Jan 15, 2018. Sea otter numbers have declined in southwestern Alaska over the past 20 years. Sea Otter Awareness Week is this Sept. 23-29. These threats have grown, even though from 2016 to 2018, the average population size reached a level that could have triggered a review for possible removal of the species from the ESA list. This work was supported in part by personalized and endangered species license plates. Washington Department of Fish and Wildlife, Olympia, Washington. 2018 Dec; 11(10): 1779–1790. 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. The fur trade wiped out the Southeast sea otter population by the early 20th century. Published online 2018 May 17. eCollection 2018 Dec. survey of the sea otter population at San Nicolas Island was completed earlier (April 15–18).

Once containing more than half of the world’s sea otters, this population segment, which ranges from Kodiak Island through the western Aleutian Islands, has undergone an overall population decline of at least 55–67 percent since the mid-1980s. This weekend (September 29-30 2018), the Seattle Aquarium will be hosting a few events where you can learn from experts about sea otters and even see an enrichment demonstration! The 3-year average of combined counts from the mainland range and San Nicolas Island was 3,128, a decrease of 58 sea otters from the previous year. Lower urchin density reduces grazing pressure on kelps, resulting in a more diverse nearshore ecosystem (Estes and Duggins 1995). Sea Otters 10.31.2018; Otters win again. Commission Reports and Publications. According to the U.S. 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.
