Conflicting Values in the Management of the Overpopulation of Wolves Essay
Conflicting Values in the Management of the Overpopulation of Wolves - Essay Example They have occupied habitats throughout the North America other than areas such as ââ¬Å"southeastern USâ⬠and parts of ââ¬Å"Californiaâ⬠(483). However, the increasing human population, coupled with the extensive development of agriculture, caused a decrease in their numbers and by the beginning of 20th-century gray wolves ââ¬Å"nearly vanished from the eastern United Statesâ⬠(483). Being ââ¬Å"ecosystem generalistsâ⬠they have distinct concepts about their surroundings and they choose their habitat based on the availability of prey, especially ungulate populations (487). In areas where their population density is high, they become a threat to humans, ungulates, and other livestock. Thus, their ultimate fate depends on the ability of humans to coexist with them and protecting their ââ¬Å"biological requisitesâ⬠(497). With a current approximate population of just over ââ¬Å"50000,â⬠the gray wolf has been placed under the category of ââ¬Å"threa tened in Minnesota and endangeredâ⬠in all states other than Alaska (497). ...à Researchers such as Smith, Peterson, and Houston (2003), point to historical evidence of Isle Royale, where restoration of gray wolves about sixty years ago has entailed the complete elimination of coyotes apart from reducing moose population. Therefore, they argue that the restoration of gray wolves to YNP will also result in ââ¬Å"similar effects to a degreeâ⬠(Smith, Peterson & Houston 2003:330). On the other hand, several others contend that the delisting of NRM gray wolf has been a premature action. Further, they consider this step as insufficient to ââ¬Å"address deficienciesâ⬠in the wildlife management policies and suggest that it will impair the maintenance of a ââ¬Å"viable metapopulationâ⬠of wolves and expose them to the risk of extirpation (Bergstrom et al 2009: 991). It is also relevant that gray wolves, as predators, play a key role in the ecological balance by rem oving ââ¬Å"sicker and weakerâ⬠animals of other species (Delisting the Gray Wolf 2013: 1). In the present situation, where the population of gray wolves keeps decreasing, it becomes necessary to maintain a metapopulation of this species as they are highly significant for balancing the ecological system. Analysis of the Controversies: Research evidence suggests that there has been a ââ¬Å"95% decreaseâ⬠in the historic range of the gray wolves that once have been abundant in the US (Curran 2011: 3). The evidence further attributes this decline to the ââ¬Å"predator control programsâ⬠that have been sponsored by the US government (3).
