Area of protected land that shares a boundary with the organization's protected land as of the end of the reporting period.
Area of protected land that shares a boundary with the organization's protected land as of the end of the reporting period.
Organizations should footnote all assumptions used. See usage guidance for further information.
Protected land assemblage is the area of protected land not controlled by the organization that is adjacent to the land controlled by the reporting organization.
This should include land area controlled by other entities as long as they form a contiguous assemblage with the protected land area directly or indirectly controlled by the reporting organization.
For many conservation objectives, large, connected areas of conserved land are more valuable than small and disconnected pieces of conserved land. This metric helps capture holistically how a specific project complements previous conservation work.
