IUCN World Commission on Protected Areas (WCPA)

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.

The Kunming-Montreal Global Biodiversity Framework, adopted in 2022, provides a framework for the effective implementation of the Convention on Biological Diversity (CBD) through four goals and 23 targets. Target 3 (known as the ‘30x30 target’) calls on Parties to conserve at least 30% of terrestrial, inland waters, and coastal and marine areas by 2030. These guidelines are designed to promote good practices relating to identifying, reporting, monitoring and strengthening OECMs.

This is the first volume in the WCPA Good Practice Guidelines that is predominantly by rangers, for rangers. The editors worked with partners to collect good practices and stories from rangers worldwide, reflecting global experience and lessons learned. The text focuses on actions that rangers, and to a lesser extent managers, can do themselves. It does not address institutional changes that would need intervention at government level.

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.

Light pollution is the human-caused alteration of outdoor light levels from those occurring naturally. It threatens ecological and commemorative integrity, interferes with amateur and research astronomy, degrades the appreciation of mythologies and cultural practices related to the night sky, mars wilderness experience and landscape beauty, carries risks to human health and wastes energy. Counterintuitively, excess outdoor lighting reduces safety and security.
