The recovery of a rare rhino species that had almost become extinct is being hailed as a conservation success in Nepal. A 2021 census counted 752 greater one-horned rhinos, up from 645 in 2015. Around 350 experts and officials traveled on elephants to complete the three-week tally. However, biologists warn the picture is still fragile because annual population growth has dropped. Nepal once had 1,000 rhinos but human migration and war caused their numbers to drop before strict conservation measures were put in place.
