sea otter population graph 2019

1). We will present preliminary results from this model. For example, a high proportion of sea otter carcasses recovered between Cayucos and Pismo Beach in recent years have white shark bite wounds, a potential explanation for the downward trend in sea otter numbers in that area. “Sea otters. Based on the graph, how did the California sea otter population change from 1997 to 2007? After their reintroduction, counts of sea otters were collected during coastal aerial and land-based sea otter surveys from 1977 to 2017 and were used to generate indices of population size. Early accounts by Spanish explorers noted otter populations as far south as San Jose and as far north as Richardson Bay. A centralized stranding response program for voluntary reports in Washington and Oregon began in 2002. The landmark 1972 legislation recognized marine mammals as a central element of their ocean ecosystems, setting population goals based on levels that would contribute to the health and stability of those ecosystems. The population of threatened southern sea otters in Elkhorn Slough, an estuary in Central California, has made a significant comeback as a result of Monterey Bay Aquarium's Sea Otter Program. Hughes said one of the reasons otter habitat has remained fragmented and why sea otters have not been able to migrate north and reestablish residency in San Francisco Bay is the presence of great white sharks near the Golden Gate. “Sea otters were associated with kelp forests only because the surviving southern sea otters off of Big Sur were in that habitat; if you go back in history, you’d be as likely to think of otters as salt marsh and seagrass animals, and indeed, there used to be more in San Francisco Bay than the entire southern population size now.”, According to Hughes and his coauthors, current southern sea otter recovery plans have not included estuaries as target habitats. The southern sea otter was widely believed to be extinct due to the expansive fur trade of the 18th and 19th centuries, which reduced the global population from between 150,000 and 300,000 to roughly 2,000. * Sea Urchin Kelp Crab Large Fish. This “may be an artifact of where the surviving population persisted,” they concluded in their paper, titled “Species recovery and recolonization of past habitats: Lessons for science and conservation from sea otters in estuaries.”, “The dogma, widely reinforced in both the scientific and popular media, is that sea otters do best in saltwater kelp forests,” said Brian Silliman, Rachel Carson associate professor of marine conservation biology at Duke University’s Nicholas School of the Environment and a partner in the study. Overall, southern sea otters have only recolonized about 13 percent of their historic range, according to the study. However, in southwest Alaska, sea otters have experienced a sharp population decline in the last 20 years. In this article you’ll get to know about the sea otter population as well as how many sea otters are left in the wild.
