In last year's harvest, more than half of Nebraska's whitetail and muley bucks were at least 2 years old, continuing a trend toward older bucks, says Kit Hams, Game and Parks Commission big-game biologist. Deer Management Units with the highest percentage of older bucks include Keya Paha, Pine Ridge, Plains and Sandhills. Whitetail densities are highest in eastern Nebraska, especially near river drainages. Frenchman, Pine Ridge, Plains, Platte and Sandhills DMUs hold the most muleys.
