Utah's big game range trend studies
Tracking changes in the health of big game winter range conditions
The ability to detect changes in vegetation composition on big game winter ranges is an important part of the DWR's big game management program. The health and vigor of Utah's big game populations are closely correlated to the quality and quantity of forage in key areas.
The majority of the permanent range trend studies are located on deer and elk winter ranges. On certain management units, however, these studies are also located on spring and summer ranges if the vegetation composition is the limiting factor for big game populations. Wildlife biologists and other land managers use range trend data for habitat improvement planning purposes, reviewing BLM and USFS allotment management plans, and as another source of information for deer and elk management plans.

Objective
Monitor, evaluate and report range trend at designated key areas throughout the state, and inform Division biologists, public land managers and private landowners of significant changes in plant community composition in these areas.
Expected results and benefits
Range trend studies in each of the state's DWR regions are resurveyed every five years, and vegetation condition and trend assessments will be made for key areas. DWR biologists, land management personnel from the USFS and BLM, and private landowners will use the range trend database to evaluate the effect of land management programs on big game habitat. Special studies (habitat project monitoring and big game/livestock forage utilization studies) will give DWR biologists and public land managers additional information to address local resource management problems. Annual reports will be readily available in hard copies from DWR regional offices, BLM and USFS offices and public libraries.
Range trend methods
Studies monitoring range trends depend greatly on site selection — especially when dealing with large geographic areas such as wildlife management units. Since it is impossible to intensively monitor all vegetation or habitat types within a unit, it is necessary to concentrate on specific sites and/or "key" areas within distinct plant communities on big game ranges.

Funding
The DWR's Range Trend Program is primarily funded by Pittman-Robertson federal aid dollars through Federal Aid Grant W-82-R, Wildlife Habitat Monitoring / Range Trend Studies. In addition, several state and federal agencies act as funding cooperators to the project. These are the Utah Division of Wildlife Resources, Bureau of Land Management and the U.S. Forest Service.
Employment opportunities
The Range Trend project hires seasonal wildlife technicians to conduct field work every year. These positions are usually advertised in January and filled by mid-March. You can see a list of currently available seasonal positions at the Utah Department of Natural Resources website or contact the project leader or an assistant project leader at the phone number below.
