Summary

Pictured is a cheetah (Acinonyx jubatus). Sarah M. Durant et al. estimated the global population of cheetahs to be approximately 7,100 individuals occupying 9% of the cheetah's historical range. Most of the cheetah's current range falls outside protected areas, where the species faces multiple threats that increase the risk of extinction. The findings suggest that the continued existence of cheetahs and other protection-reliant species depends on their survival outside as well as inside protected areas. See the article by Durant et al. on pages 528–533. Image courtesy of Sarah M. Durant.
