Index values range from 1 (low) to 3 (high), based on a modified version of the USGS SPARROW (Spatially Referenced Regression on Watershed Attributes) model. The SPARROW model simulates simulates the loading of nitrogen and phosphorus across the Chesapeake Bay watershed based on land-use, incoming nutrients from other watersheds, and atmospheric deposition. To create the index, loading rates were designated as having low, medium, and high nutrient uptake rates based on a range of uptake rates for forests and wetlands taken from the academic literature.\n\nThis data layer was created as part of the Maryland Department of Natural Resources \"Accounting for Maryland's Ecosystem Services\" program.
