This online database provides a searchable inventory of valuation studies for ecosystem services that focus on an identified ecosystem and provide monetary value for these services. Ecosystem valuation data are abundant, yet they are often hard to find. GecoServ functions as a centralized source and user-friendly interface for the information. It promotes the distribution and sharing of these valuation studies, provides researchers with background information for future studies, and helps resource managers include ecosystem services in the decision-making process.
