An Ecological Comparison of Two Stream Sections with and without Native Fish Populations, in Yellowstone National Park

Abstract

This is a brief report of a reconnaissance survey of the benthic macroinvertebrate community above and below a natural barrier to fish movement on Raven Creek, a tributary of Pelican Creek in the Lake Yellowstone watershed. This project is part of a U.S. Fish and Wildlife Service program to evaluate differences in stream ecology with and without native fish populations. The Final Report is due June 30, 1978.
