USING CITIZEN SCIENCE DATA TO EVALUATE THE EFFECTS OF LAND USE ON MACROINVERTEBRATE COMMUNITIES IN AN URBAN RIVER
As urban populations continue to grow, the stress placed upon aquatic resources continues to increase. Particularly in urban watersheds, like the Rouge River in Detroit, relative composition of land usages can impact stream biota through a variety of mechanisms. Urban watersheds provide a unique opportunity compared with rural systems in their potential for citizen science activities. We analyzed land usage in the Rouge River watershed using the 2011 National Land Cover data (USGS) for correlation with citizen science macroinvertebrate survey data (2013-2016) from the Friends of the Rouge organization to determine the impact of land use on stream biota. We examined three subwatersheds, along an agricultural-urban gradient from an upstream subwatershed with 30 percent urban development to a downstream subwatershed with 95 percent urban land use. There was a negative correlation between percent-urban land and both species richness and sensitive taxa (Ephemeroptera, Plecoptera, Trichoptera [EPT]) for each year except 2015. Conversely, there were positive correlations between both agricultural and forested land use with richness and EPT taxa each year except 2015. These findings demonstrate the utility of citizen science data to evaluate the impact of urbanization on aquatic resources.
