A watershed ecological risk assessment of Waquoit Bay, located on the south coast of Cape Cod, MA, was performed for managers to better understand the environmental impacts of human activities. An interdisciplinary and interagency workgroup identified all the stressors of concern (chemical pollution, pathogens, altered freshwater flow, nutrient enrichment/eutrophication, physical alteration of habitat, and fishing/shellfishing) and selected assessment endpoints (estuarine percent eelgrass cover, finfish diversity and abundance, scallop abundance, anadromous fish reproduction, wetland bird and piping plover habitat distribution and abundance, and tissue contamination of fish and shellfish). The workgroup later decided to focus on nutrient enrichment and its impacts on percent eelgrass cover and scallop abundance. A nitrogen loading model (NLM) was used to estimate the amount and sources of nitrogen entering the watershed, and an estuarine loading model (ELM) was used to estimate the nitrogen available to producers in shallow estuaries.
