Summary of Stranded Southern Sea Otters, 1985-2018 (ver. 3.0, June 2021) The southern sea otter (Enhydra lutris nereis), also known as California sea otter, was listed as threatened in 1977 under the Endangered Species Act. Since 1985, stranded otters from throughout their California coastal range have been collected and analyzed to inform resource management on recovery and conservation of the species. This data set is a complete 34 year compilation. Future annual stranding recovery information will be published when available. Stranded sea otters were collected by members of the sea otter stranding network (USGS, California Department of Fish and Wildlife (CDFW), Monterey Bay Aquarium (MBA), and the Marine Mammal Center (TMMC)) during routine beach walks and (more often) following...

Marbled Murrelets have been listed as Endangered by the State of California and Threatened by the U.S. Fish and Wildlife Service since 1992. Marbled Murrelets have been surveyed at sea off central California since 1995 (Becker et al. 1997), and standardized surveys to estimate abundance and productivity have been conducted...
