Big Falls Experimental Forest

Minnesota

The Big Falls Experimental Forest was established in 1961 entirely on state land that was set aside primarily for management of lowland black spruce forest. At the time, research goals included silvicultural, harvesting and utilization, and economic studies.

Climate

The climate is continental. Maximum summer temperatures are > 32 °C with high humidity (80 percent) and minimum winter temperatures to -35 °C. Growing season length is 100 to 120 days. Average annual precipitation is 500 to 640 mm. About two-thirds of precipitation occurs as rain and one-third as snow. Snow depths average 1 to 2 m. Although prolonged summer droughts occur, rainfall is usually adequate during the growing season.

Soils

No information on soils at the Big Falls EF is available.

Vegetation

Primary overstory species on Big Falls are black spruce and tamarack, with associated understory vegetation of alder, swamp birch, blueberry, calamus, sedges, grasses, bog Labrador tea, raspberry, willow, and moss.

Research, Past and Present

Black spruce regeneration, growth and yield, cutting methods, prescribed burning studies, and general wetland ecology are topics that have been studied at Big Falls.

Major Research Accomplishments and Effects on Management
