More Water for Mule Deer?
Do mule deer in Mojave National Preserve need more water? It may seem like a silly question. After all, it’s a desert—doesn’t everything need more water? Scientists at Mojave National Preserve are working with the California Department of Fish & Game (CDFG) and researchers at the University of Nevada-Reno to answer this question, and a few others.

Seeps, Springs, & Stock Tanks
The second part of the project focuses on learning more about the behavior of Mojave’s mule deer. For starters, no one knows for sure how the population size is changing. Deer have been hunted in the area since 1958. Since Mojave National Preserve was established in 1994, the average annual buck harvest has increased 50 percent, from 28 to 42 bucks per year. But buck harvest information alone is not a reliable indicator of mule deer population levels.
In addition to springs, there are also stock tanks fed by wells throughout the preserve, principally (and historically) used for watering cattle. It’s not known which of these water sources deer used regularly, or whether they depend upon such artificial water sources of survival. Furthermore, is it water availability that limits the number of deer, or is it something else, such as food availability or predators?

Where the Mule Deer Roam
Then, the mule deer were released into the wild, adorned with new accessories: two identifying ear tags and a VHF high-frequency radio collar. Some deer were also outfitted with an additional collar containing a GPS unit. After 375 days, the GPS collars automatically fall off. Analysis of the device offers researchers “hoof-by-hoof” intelligence on where the deer roam.
Over the next several years, University of Nevada-Reno graduate students and National Park Service employees will monitor their movements several times a week. Cameras installed at springs throughout the preserve will also capture individual deer movement. When a doe stops for a drink, the camera photographs an image of her numbered “earring.”

Did You Know?
Park or preserve? Like other parks with the designation of "national preserve," Mojave National Preserve is managed under the same guidelines as national parks. The main difference is that hunting is allowed in national preserves, but not in national parks.
