摘要

海獭曾经分布在北太平洋沿岸,从日本北部岛屿到墨西哥下加利福尼亚州中部。有三个公认的海獭亚种:俄罗斯或亚洲海獭(Enhydra lutris lutris);阿拉斯加或北方海獭(E. 1)。kenyoni);和加利福尼亚或南部海獭(E. 1)。(Wilson et al. 1991)。南部海獭分布在最南端,仅在加州的两个地区有种群:从圣马特奥县到圣芭芭拉县和文图拉县的大陆海岸线1历史上,据信有16000 - 20000只海獭生活在现在的加利福尼亚地区2南加州海獭在加利福尼亚受到加利福尼亚渔猎部的保护在20世纪70年代,加利福尼亚海獭的数量被限制在加利福尼亚中部海岸主要是由于担心南海獭易受石油泄漏的影响,美国鱼类和野生动物管理局(服务处)于1977.5年根据《濒危物种法》将南海獭列为受威胁物种。服务处于19826年批准了南海獭的第一个恢复计划,并于1987年发布了最终的环境影响报告。该环境影响评估评估了几种选择,包括从加利福尼亚中部海岸转移南部海獭,试图在距离南加州海岸线111公里(60海里)的圣尼古拉斯岛形成一个独立的动物群落。7,8通过迁移,该服务处希望在其历史范围内建立一个自给自足的南部海獭种群,但远离中部海岸种群,以减少自然或人为灾难导致中部海岸种群大量减少时对该物种的风险。为了实现项目目标,圣尼古拉斯岛殖民地将

First Reported Occurrence of the Southern Sea Otter Enhydra lutris lutris at California's Santa Barbara Island Since 1940
Sea otters once ranged along the North Pacific rim from the northern Japanese islands to mid-Baja California, Mexico. There are three recognized subspecies of sea otters: the Russian or Asian sea otter (Enhydra lutris lutris); the Alaskan or northern sea otter (E. 1. kenyoni); and the California or southern sea otter (E. 1. nereis) (Wilson et al. 1991). The southern sea otter occupies the most southerly range, with populations in only two areas of California: the mainland coastline from San Mateo County to Santa Barbara County and San Nicolas Island, Ventura County.1 Historically, 16,000-20,000 sea otters are believed to have resided in the area that is now California.2 The southern sea otter was afforded protection in California by the California Department of Fish and Game in 1913.3 In the 1970s, the California population of sea otters was restricted to the Central California coast.4 Primarily due to concerns about the vulnerability of this population to oil spills, the southern sea otter was listed as threatened by the United States Fish and Wildlife Service (the Service) under the Endangered Species Act in 1977.5 The Service approved the first recovery plan for the southern sea otter in 19826 and released a final environmental impact statement in 1987. This EIS evaluated several options including translocating southern sea otters from California’s central coast in an attempt to form a discrete colony of animals at San Nicolas Island, located 111 km (60 nm) off the Southern California coastline.7,8 Through translocation, the Service hoped to establish a self-sustaining southern sea otter population at a location within their historic range, but well away from the central coast population to lessen the risk to the species should a natural or man-made catastrophe decimate the central coast population. To achieve project goals, the San Nicolas Island colony would
