Conserving 0.7% of Land Could Save One-Third of Threatened Vertebrates

A new study suggests that conserving just 0.7% of global land could protect a third of threatened vertebrate species, including the critically endangered gharial. The research, led by Imperial College London, highlights the importance of focusing on Evolutionarily Distinct and Globally Endangered (EDGE) species in biodiversity-rich regions.

A recent study suggests that conserving a mere 0.7% of the world's land could significantly protect one-third of the threatened four-limbed vertebrate species. This includes the gharial, a long-snouted and critically endangered crocodile native to the Indian subcontinent.

Researchers from Imperial College London emphasized that substantial conservation gains can be achieved by targeting regions rich in biodiversity and home to 'Evolutionarily Distinct and Globally Endangered (EDGE)' species. The study revealed these species and their habitats require immediate protection to prevent extinction.

The authors charted the distribution of nearly 3,000 EDGE species, highlighting areas like Southeast Asia, the Indo-Gangetic plain, and the Amazon basin as critical. However, only 20% of these areas are currently protected and face increasing human activities. The findings were published in the journal Nature Communications.

Maximum EDGE species richness was identified in Madagascar, Mexico, and Indonesia. Lead author Sebastian Pipins stressed the urgent need for preserving unique natural habitats, noting that over 75% of EDGE species exist within a single country. Co-author Rikki Gumbs underscored the importance of national leadership in conservation efforts.
