Wyoming data: An estimated 353,000 mule deer and about 70,000 white-tails in 2015, total population of 423,000.  About 340,000 mule deer and 60,000 white-tails in 2014, total population of 400,000.  2016 Hunting Forecast. Deer populations are generally somewhat up in 2015 and 2016 after three mild winters that resulted in good fawn survival.  Good rainfall in 2016.  Deer populations are in fair shape in the north. Mule deer populations are up in the central part of the state but down in the west.  White-tails numbers are up in the Black Hills, but still down in some other areas from the 2014 EHD outbreak. Mule deer antler restrictions have been lifted in many regions. Mule deer populations are up in the Green River area.and the northern Big Horn. Down in the southernBighorn Basin from habitat decline, weather, and disease. Regional Summary   Follow the Wyoming Migration Study
     In 2013 the state had an estimated 63,000 white-tails and 374,000 mule deer, 369,000 mule deer in 2012.  The harsh winter of 2013-14 reduced the herd.  A total population of about 578,000 in 1991. Mule deer populations in Wyoming have been on the decline since the late 1980s. According to the Western Association of Fish and Wildlife Agencies mule deer populations "declined by an estimated 168,000 (31 percent) since 2000. After the 2011 hunting seasons, it was estimated there were 376,000 mule deer in the state."  About 544,000 mule deer in the year 2000. Harsh winters in 1978-79, 1983-84 (resulting in a population crash), and 1992-93, reduced populations, also a severe outbreak of EHD in 2012 reduced white-tail populations.  Few fawns survived harsh winters in 2010 and 2011.  
     A three year study is underway as part of the Mule Deer Initiative to explore why mule deer are not reaching their population goals. Reasons include drought, development, chronic wasting disease, and poor fawn production which has declined by about 20 percent in the last 25 years. To sustain hunting the herd needs about 66 fawns per 100 does, but the ratio has been below that since 1990. In 2012 it was at 63. The state is about 35 percent below objective.  Reduced stands of mahogany, a crucial winter food supply, has contributed to the mule deer population decline.
      Some deer migrate 170 miles in the Wyoming range. Over hunting on public land, habitat loss and fragmentation, and energy development are all thought to be contributing causes of the decline. Mule deer populations are generally in better shape on private land. Antelope populations have been on a steady decline over the last few years.  Hunting statistics
     Chronic Wasting Disease (CWD) was first discovered in 1979 in deer at the Wyoming Fish and Game Department’s Sybille wildlife research facility.  The first recorded CWD infection in 1967 was among captive deer at a Colorado Division of Wildlife Research Facility in Fort Collins, Colorado.
     At least 544 wolves in 2015.
     Moose populations are generally in decline with an exception of the Snowy Range herd.

The mule deer has been the most abundant big game animal in the west for nearly a decade. Now the species is in crisis and the Wyoming Cooperative Fish and Wildlife Research Unit is conducting a study to find out why. Deer Project leader Matt Hayes of the University of Wyoming sees that mule deer populations in an area south of Rock Springs are declining while elk populations are rising and investigates this dynamic. - June 21, 2016
