Using the Area of Habitat to assess the extent of protection of India's birds

India hosts multiple global biodiversity hotspots while being one of the most populous countries in the world. Here, we examine how well India has protected its avifauna, based on the fraction of their ranges falling within “protected areas.” India has protected 5% of its land this way. The issue is whether India has done better than expected in protecting its threatened species. To this end, we assessed 99 Near Threatened, Threatened, and small-ranged species by estimating their Area of Habitat (AOH). We refined published species ranges using secondary information on elevation limits and habitat preferences. More than half (52) of the species assessed have their AOH <30% of their published ranges, while 31 have <10%. India has protected 87 threatened species' AOH more than expected (>5%), and for 33 species, the proportion protected exceeds the Aichi target (>17%). When we consider the top 10% richest regions as hotspots, only 9.2% of their total area falls under India's pr...
