Research at the Andrews Forest: LTER7 (2014–2020)

The HJ Andrews Experimental Forest is a 64 km² watershed spanning 400 to 1600 m elevation on the west slope of the Cascade Range, Oregon. The site lies within the temperate wet forest biome, and is dominated by Douglas fir and western hemlock forests, a relatively large proportion of which is old growth. The Andrews Forest program has a 65-year history of research in a continually evolving context of changes in the environment, in science, and in society. We are currently in the seventh, six-year funding cycle for the Andrews Forest LTER (“LTER7”), which aims to characterize the mechanisms determining how forested mountain ecosystems respond to changes in climate, land-use, and their interactions.
