Platte River Ecology Study
Special Research Report
U.S. Fish and Wildlife Service
June 1981
This report summarizes findings of the Platte River Ecology Study. The 3-year investigation was conducted by the U.S. Fish and Wildlife Service to 1) determine the role of the Platte River Valley in contributing to the requirements of midcontinent migratory bird populations
and 2) develop guidelines for management of riverine habitats and adjacent lands supporting populations of selected species of migratory birds.
A research team formed by investigators from the U.S. Fish and Wildlife Service and several universities conducted the study. Individual investigations focused principally on various aspects of migratory bird usage of the Platte River Valley and on factors affecting habitat conditions on riparian lands.
Nearly all facets of the research program described in this report will be submitted for publication in scientific journals. Readers requiring a more detailed description of individual studies should consult the technical papers that will be forthcoming.
