An experimental forest, or experimental range, as defined by the United States Forest Service, is "an area administered ... 'to provide for the research necessary for the management of the land.'"[1][2]
Size and relation to other areas
According to the USFS, "Most Experimental Forests are large enough to contain significant stream systems and several dozen contain experimental watershed study sites with multiple paired basins." Individual experimental forests range from 0.47 to 225 km2 (120 to 55,600 acres) in area. Experimental forests are distinguished from research natural areas and intensive monitoring sites.[3]
History
The present system of 80 experimental forests and ranges began in 1908. Many experimental forest are more than 50 years old. The system provides places for long-term science and management studies in major vegetation types of the 195,000,000 acres (790,000 km2) of public land administered by the Forest Service.[4]
Experimental forests and ranges in the United States
Coram Experimental Forest in Montana is used to study western larch, Douglas-fir, forest regeneration, forest growth, silvicultural systems, climate, and hydrology.
Deception Creek Experimental Forest in Idaho is used to study sediment movement and transport, forest genetics, root disease, small tree use, and fire effects.
Desert Experimental Range in Utah is used to study cold-desert-plant communities, desertification, sheep management, rodent ecology, pronghorn antelope, soils, and bird and mammal populations.
Glacier Lakes Ecosystem Experiments Site (GLEES) in Wyoming is used to study seedling germination, nitrogen deposits, riparian hydrology, disturbance changes, tree growth, atmospheric pollutants.
Priest River Experimental Forest in Idaho is used to study woody debris, soil productivity, acid deposits, seedling development, water yield and quality, and wood decomposition.
