The elk population, while taxing the common food resources, also adversely affects native species that share the same food supply, such as the indigenous beavers. Several indigenous butterfly and plant species are harmed, especially the aspen groves that the elk herd of perhaps 3,000 animals decimates in its search for food. The Rocky Mountain National Park and the Estes Park environments are physically disrupted by the migration of the elk, ranging in size from calves to full-grown 700-pound adults. and North America have local, state, and federal policy makers searching for solutions. Environmental and CWD problems in Estes Park, Colorado and, on a greater scale, throughout the Western U.S. There is no evidence to conclude that elk CWD is transmittable to humans, and research concerning CWD and its effect on the eco-system continues. CWD affects the brain tissue of infected elk and is similar in symptoms to bovine spongiform encephalopathy (BSE), commonly known as mad-cow disease (MCD). While overhunting is a significant contributing factor, the elk’s near extinction is mainly attributed to human encroachment and destruction of their natural habitats and migratory corridors.Īs of 2010, the Rocky Mountain elk herd has been diagnosed with a serious disorder called Chronic Wasting Disease (CWD). The Rocky Mountain elk was re-introduced in 1913 to Colorado from Wyoming after the near extinction of the regional herds. The total wild population is about one million individuals. In the summer it migrates to the subalpine forests and alpine basins. The winter ranges are most common in open forests and floodplain marshes in the lower elevations. The Rocky Mountain elk ( Cervus canadensis nelsoni) is a subspecies of elk found in the Rocky Mountains and adjacent ranges of Western North America. Unsourced material may be challenged and removed.
