This coverage sets the boundary within which a range-wide conservation assessment of the Greater Sage-grouse and sagebrush habitats was conducted. Choosing the larger historical distribution as the base analysis region permitted the comparison of differences relative to the current distribution and detection of potential causes of population changes or extirpation. The conservation assessment boundary comprises the pre-settlement distribution of Sage-grouse buffered by 50 kilometers. Buffering the historical distribution permitted an evaluation of external factors that may have contributed to current trends in populations or habitats.
