Long-Term Ecological Research (LTER)/AND017: Structure and Composition of Riparian Vegetation in the H.J. Andrews Forest

It characterizes phenology of leaf-out and leaf fall, and determines the spatial distribution of foliar biomass, and timing and amount of annual foliar inputs to streams. Permanent transects of 1 m x 1 m and 5 m x 5 m plots were established along 100-150 m reaches of third-order streams in four vegetation types which represent different serial stages.

The Andrews Forest is in the western Cascade Range of Oregon in the 15,800-acre drainage basin of the Lookout Creek, a tributary of Blue River and the McKenzie River. The area elevation ranges from 1350 feet to 5340 feet and contains excellent examples of Pacific Northwest conifer forests, wildlife, and ecosystems.
