komodo island is one of the biggest island within the park, and other two major islands: Rinca and Padar, as well as numerous smaller islands creating a total surface area (marine and land) of 1817km (proposed extensions would bring the total surface area up to 2,321km2). As well as being home to the Komodo dragon, the Park provides refuge for many other notable terrestrial species such as the orange-footed scrub fowl, an endemic rat, and the Timor deer. Moreover, the Park includes one of the richest marine environments including coral reefs, mangroves, seagrass beds, seamounts, and semi-enclosed bays. These habitats harbor more than 1,000 species of fish, some 260 species of reef-building coral, and 70 species of sponges. Dugong, sharks, manta rays, at least 14 species of whales, dolphins, and sea turtles also make Komodo National Park their home.
Threats to terrestrial biodiversity include the increasing pressure on forest cover and water resources as the local human population has increased 800% over the past 60 years. In addition, the Timor deer population, the preferred prey source for the endangered Komodo dragon, is still being poached. Destructive fishing practices such as dynamite-, cyanide, and compressor fishing severely threaten the Park’s marine resources by destroying both the habitat (coral reefs) and the resource itself (fish and invertebrate stocks). The present situation in the Park is characterized by reduced but continuing destructive fishing practices primarily by immigrant fishers, and high pressure on demersal stocks like lobsters, shellfish, groupers and napoleon wrasse. Pollution inputs, ranging from raw sewage to chemicals, are increasing and may pose a major threat in the future.
