IDENTIFYING MACROINVERTEBRATE METRICS TO INDICATE ENVIRONMENTAL CONDITION OF MICHIGAN'S PALUSTRINE WETLANDS
Wetlands are some of the most productive ecosystems. They provide vital hydrologic regulation and filtration services to freshwater resources, but are often degraded by anthropogenic impacts. Eutrophication is a persistent, growing problem that can reduce wetland functioning and alter the ecosystem services they provide. Macroinvertebrates are often used as indicators of environmental quality because they are directly impacted by the physical and chemical integrity of their environment. Biota like macroinvertebrates, can provide a more comprehensive picture of the effects of different stressors over time than water quality measures. Our goal was to identify specific families and groups of macroinvertebrates that could indicate high or low concentrations of phosphorus and/or nitrogen in a wetland. We collected chemical and physical habitat characteristics, macroinvertebrates, plant tissue nutrient concentrations, soil nutrients and land use/cover (LULC) from 17 marshes of Michigan’s Lower Peninsula. We used non-metric multidimensional scaling and Pearson’s correlations to determine if macroinvertebrates aligned with particular nutrient levels. These macroinvertebrate indicators will provide managers a practical tool for evaluating the degree of eutrophication a palustrine wetland is experiencing.
