Hundreds of ecosystem services projects are currently being pursued worldwide, administered by a several conservation organizations. The Nature Conservancy is one such group. The following document is an effort to compile and summarize Nature Conservancy ecosystem services projects. We gathered this information through e-mail and phone by networking as thoroughly as possible with TNC project leaders throughout the world (see http://www.nature.org/wherewework/). We have certainly overlooked some projects, and there may be projects included that are only partially focused on ecosystem services. We anticipate continually updating this document in order to keep it useful as a portal to TNC’s broad engagement with ecosystem services. Please refer to the contacts listed for each project to learn more about the particulars of that program. A more comprehensive list of contacts is provided at the end of this document. Contacts are listed with their job title and any specific project affiliations for which they are involved.
