Big game species in the Planning Area include pronghorn (antelope), deer (mule deer and white-tailed deer), elk, moose, bighorn sheep, and mountain goat. Boundaries of the herd unit areas are established to encompass all the seasonal ranges and habitats or special life-function areas (e.g., calving and lambing areas) utilized by a more or less discreet population or herd. Because there will always be some interchange of animals between adjacent populations, and portions of populations change important use patterns over time, these boundaries are well defined, but not permanent. They do, however, represent the best available data and identify population units consistent with the most recent biological and climatic conditions. Chapter 3, Wildlife provides information about the relative size and amount of BLM-administered lands in Planning Area big game herd units. Figures K-1 through K-7 show the WGFD herd units. Specific information about population trends is available through the WGFD via the agency’s Job Completion Reports.
