Komodo Island


Komodo is one of the 17,508 islands that make up the Republic of Indonesia. The island has a surface area of 390 km² and over 2000 inhabitants. The inhabitants of the island are descendants of former convicts who were exiled to the island and who have mixed themselves with the Bugis from Sulawesi. The population are primarily adherents of Islam but there are also Christian and Hindu minorities.
Komodo is part of the Lesser Sunda chain of islands and forms part of the Komodo National Park. Particularly notable here is the native Komodo dragon.
In addition, the island is a popular destination for diving. Administratively, it is part of the East Nusa Tenggara province.Komodo National Park is located in the center of the Indonesian archipelago, between the islands of Sumbawa and Flores. Established in 1980, initially the main purpose of the Park was to conserve the unique Komodo dragon (Varanus komodoensis) and its habitat. However, over the years, the goals for the Park have expanded to protecting its entire biodiversity, both terrestrial and marine. In 1986, the Park was declared a World Heritage Site and a Man and Biosphere Reserve by UNESCO, both indications of the Park's biological importance.

Komodo National Park includes three major islands: Komodo, 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.

Today, the PKA Balai Taman Nasional Komodo and PT. Putri Naga Komodo are working together to protect the Park's vast resources. Our goals are to protect the Park's biodiversity (both marine and terrestrial) and the breeding stocks of commercial fishes for replenishment of surrounding fishing grounds. The main challenge is to reduce both threats to the resources and conflicts between incompatible activities. Both parties have a long term commitment to protecting the marine biodiversity of Komodo National Park.

The Komodo dragon (Varanus komodoensis) is a species of lizard that inhabits the islands of Komodo, Rinca, Flores, Gili Motang, and Gili Dasami, in central Indonesia.[2] A member of the monitor lizard family (Varanidae), it is the largest living species of lizard, growing to an average length of 2–3 meters (approximately 6.5–10 ft) and weighing around 70 kilograms (154 lb). Their unusual size is attributed to island gigantism, since there are no other carnivorous animals to fill the niche on the islands where they live, and also to the Komodo dragon's low metabolic rate.[3][4] As a result of their size, these lizards are apex predators, dominating the ecosystems in which they live.[5] Although Komodo dragons eat mostly carrion, they will also hunt and ambush prey including invertebrates, birds, and mammals.

Mating begins between May and August, and the eggs are laid in September. About twenty eggs are deposited in abandoned megapode nests and incubated for seven to light months, hatching in April, when insects are most plentiful. Young Komodo dragons are vulnerable and therefore dwell in trees, safe from predators and
cannibalistic adults. They take around three to five years to mature, and may live as long as fifty years.
They are capable of parthenogenesis, in which viable eggs are laid without fertilization by a male.Komodo dragons were discovered by Western scientists in 1910. Their large size and fearsome reputation makes them popular zoo exhibits. In the wild their range has contracted due to human activities and they are listed as vulnerable by the IUCN. They are protected under Indonesian law, and a national park, Komodo National Park, was founded to aid protection efforts.

The Komodo dragon is also known as the Komodo Monitor or the Komodo Island Monitor in scientific literature, although this is not very common.[1] To the natives of
Komodo Island, it is referred to as ora, buaya darat (land crocodile) or biawak raksasa (giant monitor).
