One of Asia’s most elusive predators is the Clouded Leopard. Until 2006, the term clouded leopard referred to one ubiquitous species found across the Eastern Himalayas, mainland Southeast Asia, and the islands of Borneo and Sumatara. However, extensive genetic analysis of various populations revealed two sister species of clouded leopard. The first is the Mainland Clouded Leopard, distributed discontinuously across the foothills of the Eastern Himalayas, South China, and South East Asia. The second species, the Sunda Clouded Leopard, is restricted to rainforests of Borneo and Sumatra. Physically, the latter has a darker and smaller cloud pattern than the former. Studies suggest that both species diverged relatively recently (in evolutionary terms), approximately 2-0.9 million years ago. This has been attributed to the submergence of the land bridge connecting the Sumatran and Bornean rainforests to mainland Asia, hence resulting in extreme geographic isolation and hence speciation. The population of both species has declined significantly below 10,000 individual adults. None of the subpopulations of the two species have more than 1,000 individuals. Consequently, both species have been considered “Vulnerable” by the IUCN Red List for Threatened Species. Habitat fragmentation, due to unprecedented levels of deforestation, and commercial hunting for the illegal wildlife trade are the primary threats faced by clouded leopards.In this episode, I speak to Chrishen Gomez, a Ph.D. student at the University of Oxford’s Wildlife Conservation Research Unit. He is currently a part of WildCRU’s Clouded Leopard Programme. Established in 2010, the program has since conducted long-term ecological studies on both species of clouded leopards across their range, with the aim of improving the species conservation.
