Protected Area Technical Report Series

Other effective area-based conservation measures (OECMs) are sites outside protected areas that deliver effective and long-term in situ conservation of biodiversity. Biodiversity conservation may be the primary objective of the site, a secondary objective of a site that is managed for other purposes, or it may be an unintended consequence of the way the site is managed.

Inland waters – such as rivers, lakes and other wetlands – are among the most biodiverse ecosystems on the planet. They are also the most threatened; almost one in three species is at risk of extinction and monitored populations of freshwater species have declined by 85% since 1970. The loss of these ecosystems has cascading effects on human livelihoods, cultures and our overall well-being.

Protected areas and other effective area-based conservation measures (OECMs) are important to stop the global decline in biodiversity. Systematic site-based monitoring of the state of biodiversity and conservation outcomes is necessary for evidence-based adaptive management in protected areas and OECMs.

Otras medidas eficaces de conservación basadas en áreas (OMEC) son sitios situados fuera de las áreas protegidas que ofrecen una conservación in situ eficaz y a largo plazo de la biodiversidad. La conservación puede ser el objetivo principal del sitio, un objetivo secundario de un sitio que se gestiona con otros fines, o puede ser una consecuencia imprevista de la forma en que se gestiona el sitio.

Outras medidas eficazes de conservação baseadas em áreas (OECMs) são locais fora de áreas protegidas que proporcionam conservação in situ eficaz e de longo prazo da biodiversidade. A conservação pode ser o objetivo principal ou secundário de um local que é gerido para outros fins, ou pode ser uma consequência acidental da forma como o local é gerido.
