The primary objective of the survey was to determine species composition, relative abundance, and distribution of vertebrates on the Big Hole National Battlefield. Secondary objectives included: 1) identification of unique species such as those listed as threatened or endangered by the United States Fish and Wildlife Service and estimation of their population size; b) identification of species not endemic to the area and estimation of their population size; and c) make recommendations with regard to controlled burns. Information gained from the survey will enable National Park Service managers to assess future environmental impacts and develop reliable management plans.
