The Endangered Sri Lankan leopard is the second last remaining island leopard in the world. This unique sub species is threatened since Sri Lanka’s diminishing highly fragmented forest cover is its only refugium. Currently there is almost no information on how many leopards live in the island. This creates a strong need to assess its population. The Sri-Lankan Leopard Trust will carry out leopard population surveys in three of Sri Lanka's biggest National Parks: Yala, Wilpattu and Horton Plains
