MANAGEMENT ALTERNATIVES FOR UTAH MOOSE
Since the mid-1960’s moose (Alces alces) numbers have increased significantly in northern Utah. Previous studies of the principal population, located on the north slope of the Uinta Mountains, estimated winter range carrying capacity. This report examines 2 proposed management alternatives, maximum-...
