Conservation Imperatives: securing the last unprotected
terrestrial sites harboring irreplaceable biodiversity
Ambitious biodiversity goals to protect 30% or more of the Earth’s surface by 2030 (30x30) require strategic near-term targets. To de ne areas that must be protected to prevent the most likely and imminent extinctions, we propose Conservation Imperatives—16,825 unprotected sites spanning ~164 Mha of the terrestrial realm that harbor rare and threatened species.
The role of privately protected areas in achieving
biodiversity representation within a national protected area network
As the world nears the target of protecting 17% of terrestrial environments, there remain significant gaps in achieving the ecologically representative system of protected areas (PAs) called for under the Convention on Biological Diversity.
