This synthesis report will be of interest to local, regional, state, and federal officials, as well as to other transportation professionals that work with them in "ecological impact mitigation"; that is, efforts to offset the loss or impairment of functions and values of natural habitats due to the activities of departments of transportation. This report provides an overview of current transportation agency practices, recent literature findings, and research regarding environmental impact mitigation measures, and monitoring and evaluating information for aquatic environments and related habitats, including wetlands, streams, and riparian corridors. Definitions of key terms are derived, primarily , from the Federal Highway Administration final rule on "Mitigation of Impacts to Wetlands and Natural Habitats" (23 CFDR Part 777). This report contains information culled from initial survey responses from 27 transportation agencies. Ten more transportation agencies responded to a subsequent follow-up survey designed to acquire information not addressed in the first survey. This information is combined with that from telephone interviews and reviews of applicable literature and ongoing research to address current practices across the nation.
