Colorado has abundant big game populations that provide for an economically significant and diverse amount of big game-related wildlife recreation. Mule deer populations in Western Colorado have been declining since the 1970s. Mule deer populations face more threats than ever. Anything that lowers adult doe survival will likely result in further declines in any mule deer populations that are already declining. Colorado's statewide elk population was at its peak in 2001. Elk populations are now stable, but at a lower population size. CPW transplanted moose into Colorado with five releases from 1978 to 2010 to create hunting and wildlife viewing opportunities. Moose continue to increase in number and pioneer new habitats on their own.
