Atlantic Rim buck (IMAGE) University of Wyoming Caption A mule deer buck in velvet stands on a ridge in the Atlantic Rim area of southern Wyoming. A 14-year study on a mule deer herd south of Rawlins, Wyo., has found that the herd’s ability to track springtime forage -- which supports antler growth, nursing of offspring and abundance -- declined by 38.65 percent when energy development occurred in its migration corridor.
