The Nino Konis Santana National Park is East Timor's first national park. The park, established on 3 August 2007, covers 1,236 square kilometres (477 sq mi). It links important bird areas such as Lore, Mount Paitchau, Lake Ira Lalaro, and Jaco Island. The park also includes 556 square kilometres (215 sq mi) of the Coral Triangle, an underwater area which supposedly contains the world's greatest diversity of both coral and coral reef fish. Some of the rare birds protected by this park are the critically endangered yellow-crested cockatoo, the endemic Timor green-pigeon, the endangered Timor imperial-pigeon, and the vulnerable Timor sparrow.
