Applying Science and Mapping to Safeguard Species: Half-Earth Project

October 1, 2021


Decades ago, Robert MacArthur and E.O. Wilson pioneered a theory to assess how larger conserved land areas support the survival of more species. Their original theory, developed in the 1960s, was born of research on island biogeography with the observation that larger islands contain more species, but it has since been applied more broadly to species preservation.

“The theory addresses biogeographical dynamics,” said Walter Jetz, professor and director of the Yale Center for Biodiversity and Global Change. “Larger habitat fragments and those closest to other undisturbed forest habitats hold more species, and as humans encroach and create smaller patches that are less connected, you rapidly lose species diversity.””
