Within PREF are two Research Natural Areas, Canyon Creek, 977 acres (395 ha), established in 1937, and Wellner Cliffs, 310 acres (125 ha), established in 2006.īelt, G. The Experimental Forest contains a variety of managed and reserve areas, a multitude of ecological site choices from wild to extremely disturbed areas, and all of the significant forest types and habitat associations of the region. PREF contains approximately 6,368 acres (2,758 ha) of mountainous forestland, with small areas of talus and alpine grassland. Benton Creek, Canyon Creek, and Fox Creek drain into Priest River, which cuts across the southwestern corner of the Experimental Forest. The slopes range from moderately steep to very steep. Though the main slopes face north and south, because tributary waterways also cut into ridges, a considerable number of slopes have east-west exposures. This high land is cut by a number of streams that flow east to west, with ridges between them that also run in a general east-west direction.

Mountains comprise approximately 90% of the area. Situated on the westward slope of a spur of the Selkirk Mountains, PREF contains elevations that vary from 2,200 feet (671m) at the Priest River on the western boundary, to 5,900 feet (1,798 m) at Experimental Point, 5.6 miles (9 km) to the east.

The Rocky Mountain Research Station (RMRS), headquartered in Fort Collins, Colorado, currently administers the PREF from the Moscow Forestry Sciences Laboratory, Moscow, Idaho. PREF also served as the headquarters for the District 1 (now Region 1) investigative program until 1930, when PREF was incorporated into the Northern Rocky Mountain Forest and Range Experiment Station, headquartered in Missoula, Montana. The Forest Service established the Priest River Experimental Forest in 1911 as one of the first experimental forests set aside as a forestry research center. Priest River Experimental Forest (PREF) lies 13 miles northeast of the city of Priest River, Idaho, and 23 miles northwest of Sandpoint, Idaho. Location of the Priest River Experimental Forest
