STREAM COMMUNITY RESPONSE TO ROAD CONSTRUCTION SEDIMENTS

This study investigated how aquatic macrobenthic and fish communities responded to the effects of siltation from highway construction. Community response was evaluated on the basis of community diversity and changes in the numbers of organisms and/or species. An innovative computer program calculated the diversity indices, using the sequential comparison technique. The primary response observed among the macrobenthic and fish communities was a reduction both in numbers of species and in organisms downstream from the construction. This study found that erosion-control measures as they commonly are applied in highway construction are of limited value in preventing damages to stream communities, especially in early construction stages. This indicates a need for more comprehensive and particularly more timely application of appropriate erosion-control techniques.
