Long-term research at Fraser continues to build on the data and records collected over the last seven decades. FEF is one of the only research sites in the Rocky Mountains that maintains long-term records on hydrology, climate, forest structure and growth, and responses to forest management. Fraser is unique among these sites in providing catchments that span alpine to lower subalpine ecosystems, with a full suite of site histories and environments (ages, aspects, elevations). Fraser provides the capacity for researchers to do whole-ecosystem manipulations in watersheds that are representative of high-elevation watersheds of southern and central Rockies.
