Karimata Islands

The Karimata Islands are a chain of small islands off the west coast of Indonesian Borneo, the largest of which is Karimata, being about 20 km across. It is part of Kayong Utara Regency of West Kalimantan province in Indonesia. Karimata has a wide range of ecosystems, from mangroves and tropical rain forest in the lowlands to montane shrubland on the summit of the c.1,000 m mountain. The mountain is composed of granite. A substantial population of cave swiftlets has historically been the source of birds nests for birds nest soup, but has decreased recently to near extirpation, due to overharvesting by non-indigenous collectors who have been arriving from the mainland.

A number of small villages are situated on the coast, the largest of which is Padang, on the eastern tip of the island. The island is renowned by inhabitants of the west coast of Kalimantan to have a serious malaria problem.
