Starkey Experimental Forest and Range


The Starkey Experimental Forest and Range is a unique facility with a rich history. The first research emphasized the improvement of rangelands and livestock grazing methods. The setting is ecologically similar to the interior western forest landscapes. The history of use, logging, and grazing is also typical. Current ecological conditions, both in the understory and overstory, are also typical of conditions in the interior West. However, the ungulate-proof fence enclosing 40 square miles, as well as interior fencing, provide control of herbivory effects and even the mix of herbivores (cattle, mule deer, and elk), making the Starkey a unique facility for research.

Elk in Starkey Experimental Forest


Annual precipitation on the Starkey EFR is extremely variable, but the average is 510 mm, falling primarily as winter snow. Temperatures vary from summer highs over 37 °C to winter lows of -30 °C.


Soils range from extremely shallow basaltic soil types supporting grasslands to deep volcanic ash derivatives supporting forest stands.


Typical for this elevation (1,067 to 1,524 m) in the Blue Mountains, the Starkey’s vegetation types are primarily bunchgrass scabland, ponderosa pine-bunchgrass, Douglas-fir associations, some grand fir types, lodgepole pine, and mixed conifers.

Long-Term Data Bases

For the Starkey, there are 12 years of deer and elk handling data and radio telemetry locations for deer, elk, and cattle (ongoing). In addition, there are 20+ years of varied data sets for riparian grazing in Meadow Creek. Condition and trend transects and range exclosure data began in the 1950s. Big-game exclosures with vegetation data collection will be the subject of long-term analysis.

Research, Past and Present

On the Starkey, limited research on developing techniques of survey and measurement of forage production, use, and cover was conducted on site before it was officially designated as an experimental forest in 1940. Exclosures were constructed to assess ecological change over time. A two-unit deferred-rotation grazing system was established in 1942. Practical management projects to improve livestock distribution through water development, salting, and range riding were also initiated.

A study begun in 1955 addressed the questions of proper stocking level for range improvement and animal gain, the effect of tree overstory on forage production, the effect of livestock grazing on deer and elk, and the influence of grazing on runoff and erosion. Of particular note is the initiation of research on cattle, elk, and deer interactions. Also in the 1950s, the first broad-scale study in the Pacific Northwest correlated forest and range soils inventories.

The Meadow Creek Riparian Habitat Study was initiated in 1975 as a large multidisciplinary effort that involved 11 cooperators and included research in hydrology, water chemistry, aquatic biology, fisheries, and livestock nutrition. Another significant direction change was the initiation of research on nongame wildlife. Research was also conducted on upgrading decadent forest stands with modern timber harvest concepts.

In the 1980s, riparian research continued on Meadow Creek, as did research on nongame wildlife. Study plan development and construction of fences and facilities began for the elk, deer, and cattle interactions study. The current elk, deer, and cattle interactions project was initiated in 1989 to increase our understanding of how these ungulates respond to each other, and to management activities.

Cooperative research with Oregon State University on livestock grazing management in riparian areas has continued on the Meadow Creek study pastures. Also, a cooperator at Eastern Oregon University is studying how bats use forest stands before, during, and after fuels reduction. Research on forest insect dispersion and abundance has also been conducted. Recently, a research logging entry provided treatments to remove all Starkey Experimental Forest and Range (Oregon) mistletoe-infected trees and a partial removal of mistletoe brooms for a study of logging effects on tree and flying squirrels.

Major Research Accomplishments and Effects On Management

Reseeding studies on the Starkey have helped identify the best methods for rehabilitating mountain summer ranges and those depleted by logging. The effects of grazing systems and stocking rates on deer and elk provided information still in use today. Nongame wildlife research provided information to formulate snag retention policies in regional Forest Service management plans. Research on grazing methods for riparian zone improvement provided methodology on adjusting season of use and stocking rates as an alternative to expensive fencing, and the best sequence for grazing riparian meadows, forest and grassland ranges. The first wild-land soil survey was conducted on the Starkey and provided a template for use on three adjacent national forests.

Recent studies on the Starkey have provided the following results:

  • Effective resolution of controversies surrounding management of domestic versus wild ungulates on range allotments
  • Delivery of critical knowledge regarding the management of deer, elk, and other wildlife in relation to fuels treatments to reduce fire risk
  • Effective transfer of knowledge on the compatibility of ungulate and timber management
  • Defensible options for managing roads and human activities on public lands
  • Enhanced opportunities for hunting and viewing of elk
  • A better understanding of the role of ungulate grazing in relation to forest productivity, plant succession, fire risk, and habitats for fish and wildlife
  • Information on cattle grazing distribution relative to streams and steelhead trout spawning habitat used
  • Identify factors affecting cattle distribution relative to riparian areas


Collaborators working on the Starkey include researchers from Oregon State University, University of Alaska- Fairbanks, University of Idaho, University of Montana, National Council for Air and Stream Improvement, Boise Corporation, and Oregon Department of Fish and Wildlife.

Field in Starkey Experimental ForestResearch Opportunities

Sustainable forest ecosystem management, watershed health and restoration, and recreation and viable road management could all be addressed on the Starkey. The background information on ungulate activity, roads and traffic, and vegetation and physiographic features provides an excellent data base from which to begin modeling efforts. A fuels reduction project is in place with treatments completed in 2003.

There are opportunities for collaborative efforts to pursue research on the following topics: fuels/fire management, threat of invasive weed species, insect and disease response, biodiversity issues, and riparian/water quality concerns. Small-mammal, avian, and threatened and endangered plants research opportunities also are available. Meadow Creek, a stream with an anadromous fish population, is cross-fenced and thus provides a laboratory for intensive research related to livestock use. The presence of a telemetry system for tracking ungulate movement in response to various management manipulations greatly enhances the opportunities for research.


The Starkey is located 45 km southwest of La Grande. Facilities include a headquarters residence compound, telemetry computer center, and animal handling facilities, hay barn, pens, shops, and laboratory.
