The Risk Index for aquatic ecosystems is based on the risk of land use change from urbanization or sea-level rise (SLR). Urbanization risk is calculated and classified based on past change (from 2001 NLCD to 2016 NLCD) and expected future changes (Southeast SLEUTH model). Expected changes from SLR are included in the future change expectations with urbanization (either/or) where appropriate. Risk is classified into 5 classes: 0 = Uplands (out of analysis) 1 = High Risk (Past = declines and Future =declines) 2 = Moderate Risk (Past = stable or increasing & Future = declines) 3 = Low Risk (Past = declines & Future = stable) 4 = Very Low Risk (Past = stable or increasing & Future = stable).
