In this talk, Naresh Kusi speaks about one of the endangered species “Wild Yak”. He believes that losing a species is synonymous with losing a natural heritage. The future of wild yaks of Nepal, that are ‘Critically Endangered’ in the country, is in the hands of people who strive to work on the ground to prevent the species from going truly extinct. Naresh Kusi, a native of Bhaktapur, is a wildlife biologist exploring the Himalayan landscape of Nepal. His team has generated many important findings on the high altitude wildlife of Nepal including the rediscovery of wild yak (the new five rupee note of Nepal carries the photograph of a wild yak taken by his team) and discovery of two species of birds new for Nepal.
