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.

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.

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.

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.

Tindakan konservasi berbasis area yang efektif lainnya (OECM) adalah tapak di luar kawasan perlindungan yang memberikan pelestarian keanekaragaman hayati secara in situ yang efektif dan jangka panjang.

Les autres mesures de conservation efficaces par zone (AMCEZ) concernent les sites situés en dehors des aires protégées qui assurent une conservation in situ efficace et à long terme de la biodiversité. La conservation peut être l’objectif principal du site, un objectif secondaire d’un site géré à d’autres fins, ou encore une conséquence involontaire de la manière dont le site est géré.

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.

The development of linear transport infrastructure (LTI) can have a variety of direct and indirect impacts on protected and conserved areas (PCAs) and other intact areas with high biodiversity and ecological connectivity values. Poorly planned and constructed roads, railways and canals can sever habitats, disrupt ecosystems and threaten species.

In November 2018, Parties to the Convention on Biological Diversity adopted at the 14th Conference of the Parties a definition of an "other effective area-based conservation measure" (OECM) as well as guiding principles, common characteristics and criteria for identification of OECMs (CBD/COP/DEC/14/8). OECMs may be managed for many different objectives but they must deliver effective conservation.
