The enactment of NEPA expanded the requirements for the highway professional to consider all aspects of a highway development project. Part of this assessment is the effects of highway projects, highway operations, and highway maintenance on natural resources. These effects occur at both the biological and ecological level. This book uses an ecosystem approach to impact assessments. The components and dynamics of terrestrial, aquatic and wetland ecosystem are described. Potential biological and ecological impacts of a highway project are also described. This analysis is broken down into pre-design, design, construction and operation and maintenance phases. Extensive discussions on methods of mitigating adverse impacts and enhancing the existing biological resources are included. Much material on current practices has been gathered during the presentation of a course sponsored by the National Highway Institute, Ecological Impacts of Proposed Highway Improvements. Case studies and references are used extensively to provide the reader with a chance for more in-depth review of a particular practice. /FHWA/
