Usage Guidance

  • The length of adjacent protected land is the length of the perimeter of the organization's protected land that is also on the perimeter of other protected land not controlled by the reporting organization.
  • This metric is intended to capture the boundary of protected lands which are immediately adjacent to already-protected land parcels, thus compounding the total amount of protected land.
  • 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.
