Flora and fauna
[edit]
The hot and dry climate of the park, characterized by savannah vegetation, makes it a good habitat for the endemic Komodo dragon (Varanus komodoensis). Their populations are restricted to the islands of Komodo (1,700), Rinca (1,300), Gili Motang (100), Gili Dasami (100), and Flores (c. 2,000), while extinct on Padar.
The park also has areas of rainforest, deciduous forest and mangroves. The parks's savannah vegetation features lontar palm (Borassus flabellifer) and grass species including Chloris barbata, Heteropogon contortusand Themeda triandra. Deciduous forests feature species including Cassia javanica, Diospyros javanica, Harrisonia brownii, Murraya paniculata, Oroxylum indicum, Piliostigma malabaricum, Schleichera oleosa, Sterculia foetida and Tamarindus indica.
Cloud forests appear only in few areas above 500 metres but they provide habitat to species, some endemic, including Ficus drupacea, Glycosmis pentaphylla, Podocarpus neriifolius, Terminalia zollingeri and Uvaria rufa. Coastal vegetation includes mangrove forest, which generally appear in the sheltered bays of the three larger islands. Mangrove species include Avicennia marina, Bruguiera gymnorhiza, Rhizophora stylosa and red mangrove (Rhizophora mangle).
Fringing and patch coral reefs are extensive and best developed on the north-east coast of Komodo. The park is rich in marine life, including whale sharks, ocean sunfish, manta rays, eagle rays, pygmy seahorse, false pipefish, clown frogfish, nudibranchs, blue-ringed octopus, sponges, tunicates, and coral.
Varieties of cetaceans inhabit in adjacent waters from smaller sized dolphins to sperm whales and even blue whales. Omura's whales, one of the least known of rorquals have been confirmed to range waters within the park. Endangered dugongs still live in Komodo areas as well.
The terrestrial fauna is of rather poor diversity in comparison to the marine fauna. The number of terrestrial animal species found in the park is not high, but the area is important from a conservation perspective as some species are endemic. Many of the mammals are Asiatic in origin, including the rusa deer, wild boar, water buffalo, crab-eating macaque and civet. Several of the reptiles and birds are Australian in origin, such as the orange-footed scrubfowl, the lesser sulphur crested cockatoo, and the helmeted friarbird.
The most famous of Komodo National Park's reptiles is the Komodo dragon (Varanus komodoensis). It is the world's largest lizard and is among the world's largest reptiles; the females can reach a length of 2 to 2.5 m (6.6–8 ft) and a 70 kg weight, the males a length of 3 m (10 ft) and up to 136 kg (300 lb) weight, but the average is respectively of 68 to 73 kg (150 to 161 lb) weight for a 2.29 m (7.5 ft) length and 79 to 91 kg (174 to 201 lb) weight for a 2.59 m (8.5 ft) length.
Twelve terrestrial snake species are found on the island in addition to marine species. Snakes include the Javan spitting cobra (Naja sputatrix), eastern Russell's viper (Daboia siamensis), Lesser Sunda Islands pit viper (Trimeresurus insularis), blue lipped sea krait (Laticauda laticaudata), and Timor python (Python timoriensis). Lizards include nine skink species (Scinidae), geckos (Gekkonidae), limbless lizards (Dibamidae), and the monitor lizards such as the Komodo dragon (Varanidae). Frogs include the Asian bullfrog (Kaloula baleata), the endemic Komodo cross frog (Oreophryne jeffersoniana) and Oreophryne darewskyi. Frogs are typically found at higher, moister altitudes. The saltwater crocodile (Crocodylus porosus) was once present within the park in coastal areas including mangrove swamps but is now extinct within the area.
Mammals found within the park include the Timor rusa deer (Cervus timorensis), the main prey of the Komodo dragon, horses (Equus sp.), water buffalo (Bubalus bubalis), wild boar (Sus scrofa vittatus), crab-eating macaque (Macaca fascicularis), Asian palm civet (Paradoxurus hermaphroditus lehmanni), the endemic Rinca rat (Rattus rintjanus), and fruit bats. Domestic mammals on within the park include goats, cats and dogs which are feral.
One of the main bird species is the orange-footed scrubfowl (Megapodius reinwardti), a ground dwelling bird. In areas of savanna, 27 species were observed. The zebra dove (Geopelia striata) and spotted dove (Spilopelia chinensis) were the most common species. In mixed tropical deciduous habitat, 28 bird species were observed, and helmeted friarbird (Philemon buceroides), green imperial pigeon (Ducula aenea), and lemon-bellied white-eye (Zosterops chloris) were the most common. Other birds include vibrantly coloured species such as green junglefowl (Gallus varius), great-billed parrot (Tanygnathus megalorynchos), and the critically endangered lesser sulpher crested cockatoo (Cacatua sulphurea). Two eagle species are found in the park, the white-bellied sea eagle and the extremely rare Flores hawk-eagle which is present on Rinca and Flores and reported but unconfirmed on Komodo Island.
