Fig. 3: Range size protection and threat status of terrestrial vertebrate species in drylands.
From: Global evaluation of current and future threats to drylands and their vertebrate biodiversity
a–d, Amphibian (a), bird (b), mammal (c) and reptile (d) species in drylands (≥50% global range in drylands). Inner circles show proportion of species with range size protected (IUCN categories I–IV): orange, 0% range protected; blue, 0–10% range protected; green, 10–100% range protected. Outer circles show proportion of IUCN threatened species: dark orange, threatened (IUCN categories CR, EN and VU); dark green, non-threatened (IUCN categories Near Threatened (NT) and Least Concern (LC)); grey, data deficient (IUCN category Data Deficient (DD)); n, number of species; parentheses, number of endemic species (>99% range in drylands).
