Forests like the HJ Andrews Experimental Forest, a National Science Foundation (NSF) Long Term Ecological Research (LTER) site located in the western Cascade Range of Oregon, play an important role in the provision of abundant clean water. Research studies at the Andrews Forest LTER focus on successional changes in ecosystems, forest-stream interactions, population dynamics of forest stands, patterns and rates of decomposition, and disturbance regimes in forest landscapes.
