Other Effective Area-based Conservation Measures (OECM)

The governments of the world adopted the following definition of an OECM in 2018: “A geographically defined area other than a Protected Area, which is governed and managed in ways that achieve positive and sustained long-term outcomes for the in-situ conservation of biodiversity, with associated ecosystem functions and services and where applicable, cultural, spiritual, socio–economic, and other locally relevant values”. OECMs complement protected areas through sustained, positive conservation outcomes, even though they may be managed primarily for other reasons. These sites are documented in the World Database on OECMs. This definition was only recently adopted and most countries have not yet provided data, but this does not mean that no OECMs exist in those countries. The World Database on OECMs is available on the Protected Planet website.
