摘要: |
A traffic-noise study was conducted to determine the impact that a highway reconstruction project would have on a habitat area for the least Bell's vireo, a federally protected songbird. The Federal Highway Administration (FHWA) and California Department of Transportation policies do not address the impact of noise on wildlife species; the study was conducted in response to a requirement of the U.S. Fish and Wildlife Service. Several mitigation measures were considered, including approximately 1200 m (4,000 ft) of temporary noise barriers. The outcome of the study was to provide funds for in-kind mitigation through habitat restoration rather than direct mitigation of noise impacts. This study contributes to a growing precedent of considering noise mitigation specifically for the protection of wildlife and raises several policy issues. Despite the increasing number of noise-mitigation projects for endangered birds and the commitment of significant funds to these undertakings, there remains a lack of firmly based noise-impact criteria and guidelines for noise mitigation. |
