InVEST is a family of free and open-source tools used to map and value goods and services from nature that are essential for sustaining and fulfilling human life. If properly managed, ecosystems yield a flow of services that are vital to humanity, including the production of goods, life-support processes, and life-fulfilling conditions, and the conservation of options. InVEST, which stands for Integrated Valuation of Environmental Services and Tradeoffs, enables decision makers to assess the trade-offs associated with alternative choices and identify areas where investment in natural capital can enhance human development and conservation in terrestrial, freshwater, and marine ecosystems.
