High conservation values (HCV) are biological, ecological, social or cultural values that are considered to be outstandingly significant or critically important at local, national, regional or global levels. All natural ecosystems and many human produced habitats possess some inherent conservation values, including the presence of rare or endemic species, provision of ecosystem services, sacred or cultural sites or resources that local communities rely on for income and subsistence. Sustainable management requires the identification and management of these values so that they are protected and enhanced for the greater good.
