The easternmost area of East Timor consists of the Paitchau Range and the Lake Ira Lalaro area, which contains the country's first conservation area, the Nino Konis Santana National Park. It contains the last remaining tropical dry forested area within the country. It hosts a number of unique plant and animal species and is sparsely populated. The northern coast is characterised by a number of coral reef systems that have been determined to be at risk.
