The National Park Service is beginning to develop a plan to analyze potential strategies for managing non-native mountain goat populations spreading through Grand Teton National Park and the John D. Rockefeller, Jr. Memorial Parkway. Park Spokesperson Jackie Skaggs says the assessment is intended to examine the impacts of the non-native mountain goats which could include the effects on native bighorn sheep. She says it has been determined that the mountain goats that were introduced into the Palisades area of Idaho have pneumonia pathogens which would pose a potential risk for the Teton bighorn sheep herd. She says the study will also analyze the resource impacts they might have that would compete with the native bighorn sheep population and their impacts on the park’s subalpine vegetation from the grazing of mountain goats. Skaggs says although mountain goats are native to northern mountain ranges in the western United States, including some in northern Idaho and Montana, they were transplanted into the Snake River Range, outside their historical range, by the Idaho Fish and Game Department in 1969 and have since widened their range. Public comments will be accepted during a scoping period from November 12 through December 13th.
