Habitat Preservation for Midwest Stream Fishes-Principles and Guidelines

摘要

The degradation of running water resources is at least partly due to a lack of understanding of the physical and biological dynamics of stream and river ecosystems and to the lack of a comprehensive, integrated approach to watershed management. The report outlines such an approach, reviews physical and biological dynamics and presents a set of habitat preservation guidelines for maintaining ecological integrity, with emphasis on warm-water fish communities. Also presented are programs dealing with water resource problems in agricultural areas, with suggested institutional approaches for halting and reversing stream and river degradation.
