Mule deer are an icon of the West and, in many ways, they reflect what's happening with habitat quality, connectivity and balance in our natural systems. As a species, mule deer face numerous challenges and threats. At the Utah Division of Wildlife Resources, we are dedicated to supporting the success of our state’s mule deer herds through monitoring and research as well as adaptable management of habitat and predators.

Management matters
Mule deer are the most abundant big game animal in Utah and are of high interest to both hunters and wildlife watchers. It's vital that we protect and improve mule deer habitat if we hope to support their populations and meet management goals.
Many factors have reduced the quality and quantity of deer habitat, including drought, invasive plants, wildfires, land development and more. With habitat loss, Western mule deer populations have also declined. The Utah Division of Wildlife Resources has invested in a statewide, long-term effort to restore habitat and help our mule deer herds. At the forefront of this effort is Utah's Watershed Restoration Initiative.
Habitat and precipitation are often the largest driving factors of deer populations, but predation can also significantly affect deer numbers. Impacts to deer populations from predators are most significant when combined with extreme weather and/or habitat impacts. For example, after a harsh winter that results in the deaths of many deer, predator populations may remain at higher levels and prevent deer populations from recovery.
Utah's ongoing GPS collar deer survival study gives us insights into the level of predation that's occurring, which predators are killing deer, and when and where those deaths are happening. After predation hits a certain level, a deer population is unable to grow. We've been able to identify units where predation is limiting deer population growth. Those are areas where we've made management changes to reduce predator densities to help mule deer.
