Utah wildlife biologists set a population objective of 325 bison by 2012 for the Henry
Mountain herd. As bison reproduce rapidly and the herds have been larger than this in the past, a decision was made to reduce the size of the herd. To achieve this objective and increase overall genetic diversity,
