Causes Of Decline In Sea Otter

296 Words2 Pages

Decline in Sea Otter Population During the pacific maritime fur trade in 1969, sea otters were hunted until they were almost extinct. After that incident, sea otter hunting was prohibited by international treaty in 1911, because of this a dozen remnant colonies survived. While the North Pacific Ocean recovered at rates of 17-20% in the first year, the population in California hasn’t grown at more than one-third of that rate and they are currently listed as threatened under the Endangered Species Act. Even though the sea otter population in California is declining, the geographic range of the population is expanding to the north as well as the south and its brought sea otters in the south closer to the potential effects of oil and gas development,

  • Essay On Anti Wolf Reintroduction

    1750 Words  | 7 Pages

    Sixty years after the extirpation of wolves in the Northern Rockies and Great Plains of America, biologist and ecologist in Yellowstone National Park reintroduced wolves into a declining ecosystem that once thrived during their presence. The reintroduction brought immense controversy into the West and continues to stir outrage among anti-wolf groups. These anti-wolf supporters argue wolves are ruthless predators that cause destruction to natural environments and livestock. Conversely wolf advocates and scientists suggest that wolves are a keystone species that are essential to the natural regulation of our Western ecosystems. Although pro and anti-wolf advocates can agree that wolves have an effect on livestock, ungulate populations and ecosystems,

    While otters are considered secure globally, the southwestern stock in Alaska is threatened. According to Alaska's Department of Fish and Game, http://www.adfg.alaska.gov/index.cfm?adfg=seaotter.main "in southwest Alaska, sea otters have experienced a sharp population decline in the last 20 years," while the Southeast and Southcentral stocks have stabilized or increased. In an email exchange with Webber, he told me that the otters washing up were assumed to be non-threatened Southcentral northern sea otters because of the location of where they came ashore. Otters have a unique history in Alaska. They bounced back from the fur trade, that began in the 1700s, that almost wiped them out.

    The number one priority should be to increase the survival rates of the female juvenile monk seals; doing so will ultimately increase the population size. With the programs such as Head Start and the translocation program at French Frigate Shoals, there was evidence of improvement in the monk seal population, but as always there was a decline that followed. The current Recovery Plan for the Hawaiian Monk Seal states that for the monk seal to be downlisted from endangered to threatened, the population needs to be more than 2,900 individuals in the Northwestern Hawaiian Islands and that at least 5 of the 6 main sub-populations need to have more than 100 individuals (National Marine Fisheries Service, 2007). For this to occur, the main criteria that needs to be addressed is the pup and juvenile survival rates. The Hawaiian monk seal population cannot continue to survive and grow if less juvenile female pups are reaching reproductive age and not surviving, this has caused the current decrease in Hawaiian monk seal populations to continue to decrease and to decrease more rapidly (Norris et al, 2011).

DDT is a chemical that was used to control mosquitoes, and it caused a thinning of the eagle egg shells.

Some rare birds that can be seen on special occasion are Bald Eagles, White Ibises, Pine Warblers, Red Crossbills, and over fifty other rarities. Some common birds are: killdeer, Caspian terns, American Avocets, Great Egrets, burrowing owls, Black-necked stilts, and Black skimmers (5). One species, the Yuma Clapper rail, relies heavily on the survival of the Salton Sea because around 40% of all Yuma Clapper rails in the United States live in the basin.

When this happens it causes unnecessary mental stress which can cause deaths of Shamus or trainers. For example, a notorious Shamu named Tilikum just recently died in captivity January 6, 2017. Tilikum was involved in the death of three people: a trainer at the now-defunct Sealand of the Pacific, a man trespassing in SeaWorld Orlando, and a Seaworld Orlando trainer. This is what happens when animals are held in a small confined area.

    The successful return of sea otters on North America’s west coast Though the Gold Rush of 1849 is considered one of California’s significant historical events, the Californian Fur Rush is much overlooked in Pacific America’s history. Dating as far back as 1741, the Californian and Alaskan coasts were targeted by American, English, Spanish, French and Russian fur traders harvesting the warm pelts of the sea otter, fur seal, beaver, river otter, marten, fisher, mink, fox, weasel, and harbor seal. Sea otters (Enhydra lutris) were particularly overhunted and their populations suffered serious fragmentation up the west coast, coming dangerously close to eradication in this area (Estes, 1990).

With the depletion of wildlife, the United States began to recognized the importance of wildlife on the culture, economy, and religion of Native American tribes. State agencies now preside over fish and game to closely control the hunting of wildlife by setting limits on methods, seasonal harvest, and size of animals to ensure a healthy population. The Marine Mammal protection act of 1972 states “recent legislation generally forbids the taking, possession, or sale of designated species by any person subject to federal jurisdiction acting without federal permission” (U.S.C. 1372
