The Island Research Natural Area: guidebook supplement 35.

The Forest Service of the U.S. Department of Agriculture is dedicated to the principle of multiple use management of the Nation's forest resources for sustained yields of wood, water, forage, wildlife, and recreation. Through forestry research, cooperation with the States and private forest owners, and management of the national forests and national grasslands, it strives—as directed by Congress—to provide increasingly greater service to a growing Nation. The U.S. Department of Agriculture (USDA) prohibits discrimination in all its programs and activities on the basis of race part of an individual's income is derived from any public assistance program. (Not all prohibited bases apply to all programs.) Persons with disabilities who require alternative means for communication of program information (Braille, large print, audiotape, etc.) should contact USDA's TARGET Center at (202) 720-2600 (voice and TDD). A near-pristine example of the Juniperus occidentalis/Artemisia tridentata/ Pseudoroegneria spicata plant association with localized examples of the Juniperus occidentalis/Purshia tridentata/Pseudoroegneria spicata plant association, Jefferson County, Oregon. established to represent examples of the western juniper/big sagebrush/bluebunch wheatgrass (Juniperus occidentalis/Artemisia tridentata/Pseudoroegneria spicata), and the western juniper/big sagebrush-antelope bitterbrush/bluebunch wheatgrass (Juniperus occidentalis/Artemisia tridentata-Purshia tridentata/Pseudoroegneria spicata) plant associations.ment (OPRD) owns surrounding lands, including a <0.1-ha portion on the summit. As an agent of BLM and CRNG, OPRD monitors and controls access into the RNA, and actively participates in management of the area. Scientists and educators wishing to visit or use the RNA for scientific or educational purposes should contact the Prineville BLM field office manager in advance and provide information about research or educational objectives, sampling procedures , and other prospective activities. Research projects, educational visits, and collection of specimens from the RNA all require prior approval. There may be limitations on research or educational activities. The Island RNA is part of a federal system of such tracts established for research and educational purposes. Each RNA is a site where natural features are protected or managed for scientific purposes and natural processes are allowed to dominate. Their main purposes are to provide: • Baseline areas against which effects of human activities can be measured or compared. • Sites for study of natural processes in undisturbed ecosystems. • Gene pool preserves for all types of organisms, especially rare and endangered types. Of the 183 federal RNAs established in Oregon and Washington, 45 are described in Federal Research Natural Areas in Oregon and Washington: A Guidebook for Scientists and Educators. 2 Supplements to …
