The Priest River Experiment Station was established in 1911 as the center for forest research in the productive forests of northern Idaho, western Montana, and northeastern Washington. Located out in the forest of northern Idaho, 15 miles from the nearest small town, it was to be the hub of forest research in this large forested area. Within a few years it became apparent that the range of conditions requiring study did not occur on the Priest River Experimental Forest and that the Station was too isolated to serve as the center for research. Thus, Missoula, Montana, headquarters for the National Forests of the region, became the hub of research and the Priest River Experimental Forest a site for intensive studies and experimentation, as a work center, and as a demonstration and educational facility. The Missoula Station developed into the Northern Rocky Mountain Forest and Range Experiment Station and took on wide responsibilities for research on management of forest and range lands and utilization of timber products. In 1954, it was combined with the Intermountain Forest and Range Experiment Station. The Intermountain Station with headquarters at Ogden, Utah, has many laboratories and field facilities scattered over the States of Utah, Nevada, Idaho, and Montana. The contribution of the Priest River Experimental Forest, one of these field stations, over the years has been as a field laboratory and support facility. I have tried, therefore, to present the Priest River Experimental Forest in this role and to limit this account largely to the people who used the Experimental Forest and their research programs.
