Extent of available data.
This data layer is the Environmental Benefits (EB) Index. It was developed by the Minnesota Board of Water and Soil Resources and the Natural Resources Research Institute. The EB Index is a composite score of multiple ecological benefits. Its components include soil erosion risk, water quality risk, and wildlife habitat quality. The scores are a relative ranking across most of the state. This allows users to rank areas of interest using multiple ecological criteria simultaneously. Although it was developed to help identify and rank areas for conservation efforts, the EB Index is useful for many purposes.
