Black Footed Ferret Essay Example For Students

Black Footed Ferret Essay In the past three decades very few endangered species have been restored toviable populations. The black footed ferret (Mustela nigripes) was believed tobe the most endangered mammal in the united states. It is a small mink sizedcarnivore of the Great plains and intermountain basins The ferrets appear to beobligatory predators on the prairie dogs and once occupied a range essentiallyidentical to that of the prairie dogs. They prey on them and also use theirburrows for shelter and nesting. The prairie dogs are considered agriculturalpests and competitors with livestock since white settlement first began in theAmerican west. Large scale rodent control programs were implemented by the stateand federal governments. They drastically reduced the population of prairie dogs(and other species related to the prairie dog ecosystem) through trapping,gassing and poisoning. These poisoning programs were considered a major cause ofthe ferrets demise. But, the main cause was the loss of the ferrets preybase and appropriate habitat. Their remaining habitat was fragmented thusleaving the ferret population vulnerable to extinction from various causesincluding inability to find mates, inbreeding depression, environmental events,and disease of ferrets and their prey. The ferrets were believed to be extinctin 1974, but in 1981 a ferret was discovered in Meeteetsee, Wyoming when a ranchdog killed an unusual animal eating from its food dish and the rancher took thecarcass to a knowledgeable taxidermist. This was viewed as a rare chance torecover the species. In 1985, a catastrophic disease struck the small ferretpopulation, and most remaining animals were taken into captivity. Captivebreeding was initiated, and reintroduction into the wild from the captivepopulation began in 1991. The ferret is just one of more than 900 species listedunder the Endangered Species act as either threatened or endangered. Over threethousand more species wait on a list of candidates for such status, but in the1980s over thirty-four species went extinct while on the waiting list (Cohn,1993). Is the ferret program representative of the national effort to recoverspecies? Main body: United States policy on endangered species, including theferret and hundreds of other plants and animals, is codified in the 1973Endangered Species act (ESA ,as amended, U.S. Congress 1983, Bean 1991) . Thispiece of legislation sets a national goal the prevention of any furtherextinction and the restoration of species currently threatened with extinction. The ESA is a highly popular piece of legislature because no one would advocatethe killing of an entire species. But the simple goal of saving a species cloaksa complicated process. The ferret case is a good illustration of how the ESA isactually outfitted, how and state officials and others tackle the complex workof restoring species, and how problems come about in nearly all recovery plans. In short, the ferret rescue is a measure of how the ESA really works. Afterfinding the small population in Wyoming, in 1981, one might expect a well ledand smoothly coordinated recovery effort to have been quickly organized to savea species that had been recognized as Americas most endangered mammal. Manyuniversities, conservation organizations, state and federal agencies, and localpeople were willing to help. Collectively they command substantial resources,not only in terms of money: national and international expertise on populationgenetics and small population management, experienced field researchers, testedbreeding facilities, and support staffs from major zoos. All that was needed forthe ferrets to be restored swiftly, professionally, and efficiently was a meansto bring the talent together in a productive well organized program. Under theESA, the task of organizing recovery efforts is the responsibility of thefederal government acting through the U.S. Fish and Wildlife Service and theU.S. National Marine Fisheries Service. Federal officials had numerous optionsopen to them at the start of the ferret program, one of which was to functionlike administrators of a large hospital, pulling together a world-classprofessional team, supporting the necessary work with adequate funding,equipment and facilities, and relying on the teams judgment to bring aboutthe patients recovery. But this model was not selected. The ferret programwas organized and operated very differently. Section 6 of the ESA requires thatstates be involved to the maximum extent practicable. Early in 1982,the federal government turned the main responsibility for ferret restorationover to the state of Wyoming. Almost immediately, problems began to emerge. 5 Most Influential People In American History EssayBibliographyAmerican Society of Mammologists. 1986.
