The impact to wetlands from urbanization (as measured by the degree of impervious surface within the watershed) on benthic macroinvertebrates was determined in the spring of 1994 in twelve wetlands in Middlesex County, Connecticut. The sites were selected to represent a gradient of urban impact. Watershed and wetland characteristics were recorded from which a summarized Habitat Assessment score was derived for each wetland. Results of this sutdy support the concept that benthic macroinvertebrate response to the degree of imperviousness is a useful index of impact from urbanization on freshwater aquatic bed wetlands.
