Species Diversity near Clear-cuts

Question: Do clear-cuts have adverse effects on the diversity of species that hatch in streams?

Study design: The study site was “Two Girls Peak” area within Willamette National Forest. Three first order streams with the same altitude and slope were chosen. One was in a clear cut (CC), one was in an area that had been logged but with a riparian buffer zone (BUF), and the third was in an unlogged forested area (FOR). Five emergent traps, each set 5 m apart, were set into each stream directly over the water. They were all left for the same two week period during July 2005, and then collected.
