National Ecosystem Classification System (NESCS) Plus Glossary

The National Ecosystems Classification System-Plus (NESCS Plus, pronounced “nex-us plus”) is a robust, step-by-step resource for tracing the links between natural ecosystems and human well-being. The main purpose of NESCS Plus is to serve as a framework for analyzing how changes to ecosystems impact human welfare. This system can aid in the analysis of different types of environmental management actions, policies, and regulations. Potential applications include, but are not limited to, cost-benefit analysis of environmental programs, natural capital accounting, and measurement of “green” gross domestic product (green GDP). Though NESCS Plus is not a valuation or accounting system, it is designed to support systematic and comprehensive accounting of changes in final ecosystem services (FES).
