Headwater Stream Macroinvertebrates of the H.J. Andrews Experimental Forest, Oregon, 2003-2004

Recent studies of headwater streams have demonstrated their importance to overall watershed biodiversity, nutrient cycling, and energy flux. However, little attention has been paid to long-term effects of forest harvest on macroinvertebrate communities in headwater streams. This study investigated headwater stream macroinvertebrate communities in the H.J. Andrews Experimental Forest, Oregon, U.S.A and used a paired-stream study design to examine if long term legacies of prior forest harvest existed for communities of stream macroinvertebrates. This study also examined correlations of macroinvertebrate life-history traits with site physical variables.
