Fraser

Fraser Biosphere Reserve and Experimental Forest is situated on the west side of the Continental Divide in north-central Colorado and encompasses the entire watershed of Main St. Louis Creek, a tributary of the Fraser River.

The Fraser Experimental Forest was established in 1937 as an outdoor research laboratory to study timber, water, wildlife management, and their integration in the high elevation subalpine coniferous forests.

It is one of few sites in the Rocky Mountains that maintains long-term records on hydrology, climate, forest structure and growth, and responses to forest management.

Ecological Characteristics

Fraser Biosphere Reserve and Experimental Forest is situated on the west side of the Continental Divide in northcentral Colorado and encompasses the entire watershed of Main St. Louis Creek, a tributary of the Fraser River.

The Fraser Experimental Forest was established in 1937 as an outdoor research laboratory to study timber, water, wildlife management, and their integration in the high elevation subalpine coniferous forests.

It is one of few sites in the Rocky Mountains that maintains long-term records on hydrology, climate, forest structure and growth, and responses to forest management. Fraser Biosphere Reserve includes subalpine forests and alpine tundra typical of the central Rocky Mountains. In the forested areas below the timberline, Engelmann spruce (Picea engelmannii) and subalpine fir (Abies lasiocarpa) are predominant trees, at higher elevations, on north slopes, and along streams.

Lodgepole pine (Pinus contorta var. latifolia) is the predominant tree at lower elevations and on drier upper slopes. The majority of the forest was initiated after a fire in 1685. Pockets of older trees exist in draws and at higher elevations.
