Komodo National Park Part II



LOCATION :
Komodo National Park lies in the Wallacea Region of Indonesia, identified by WWF and Conservation International as a global conservation priority area. The Park is located between the islands of Sumbawa and Flores at the border of the Nusa Tenggara Timur (NTT) and Nusa Tenggara Barat (NTP) provinces. It includes three major islands, Komodo, Rinca and Padar, and numerous smaller islands together totaling 603 km2 of land. The total size of Komodo National Park is presently 1,817 km2. Proposed extensions of 25 km2 of land (Banta Island) and 479 km2 of marine waters would bring the total surface area up to 2,321 km2.

HISTORY :
Komodo National Park was established in 1980 and was declared a World Heritage Site and a Man and Biosphere Reserve by UNESCO in 1986. The park was initially established to conserve the unique Komodo dragon (Varanus komodoensis), first discovered by the scientific world in 1911 by J.K.H. Van Steyn. Since then conservation goals have expanded to protecting its entire biodiversity, both marine and terrestrial. The majority of the people in and around the Park are fishermen originally from Bima (Sumbawa), Manggarai, South Flores, and South Sulawesi. Those from South Sulawesi are from the Suku Bajau or Bugis ethnic groups. The Suku Bajau were originally nomadic and moved from location to location in the region of Sulawesi, Nusa Tenggara and Maluku, to make their livelihoods. Descendents of the original people of Komodo, the Ata Modo, still live in Komodo, but there are no pure blood people left and their culture and language is slowly being integrated with the recent migrants. Little is known of the early history of the Komodo islanders. They were subjects of the Sultanate of Bima, although the island’s remoteness from Bima meant its affairs were probably little troubled by the Sultanate other than by occasional demand for tribute.

TERRESTRIAL ECOSYSTEMS :
The terrestrial ecosystems are strongly affected by the climate: a lengthy dry season with high temperatures and low rainfall, and seasonal monsoon rains. The Park is situated in a transition zone between Australian and Asian flora and fauna. Terrestrial ecosystems include open grass-woodland savanna, tropical deciduous (monsoon) forest, and quasi cloud forest. Due to the dry climate, terrestrial plant species richness is relatively low. The majority of terrestrial species are xerophytic and have specific adaptations to help them obtain and retain water. Past fires have selected for species that are fire-adapted, such as some grass species and shrubs. Terrestrial plants found in Komodo National Park include grasses, shrubs, orchids, and trees. Important food tree species for the local fauna include Jatropha curkas, Zizyphus sp., Opuntia sp., Tamarindus indicus, Borassus flabellifer, Sterculia foetida, Ficus sp., Cicus sp., ‘Kedongdong hutan’ (Saruga floribunda), and ‘Kesambi’ (Schleichera oleosa).

TERRESTRIAL FAUNA :
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 (e.g., deer, pig, macaques, civet). Several of the reptiles and birds are Australian in origin. These include the orange-footed scrubfowl, the lesser sulpher-crested cockatoo and the nosy friarbird. Reptiles: The most famous of Komodo National Park's reptiles is the Komodo Dragon (Varanus komodoensis). It is among the world's largest reptiles and can reach 3 meters or more in length and weigh over 70kg. To find out more about this fascinating creature click

Other than the Komodo Dragon twelve terrestrial snake species are found on the island. including the cobra (Naja naja sputatrix), Russel’s pit viper (Vipera russeli), and the green tree vipers (Trimeresurus albolabris). Lizards include 9 skink species (Scinidae), geckos (Gekkonidae), limbless lizards (Dibamidae), and, of course, the monitor lizards (Varanidae). Frogs include the Asian Bullfrog (Kaloula baleata), Oreophyne jeffersoniana and Oreophyne darewskyi. They are typically found at higher, moister altitudes. Mammals: Mammals include the Timor deer (Cervus timorensis), the main prey of the Komodo dragon, horses (Equus sp.), water buffalo (Bubalus bubalis), wild boar (Sus scrofa vittatus), long-tailed macaques (Macaca fascicularis), palm civets (Paradoxurus hermaphroditus lehmanni), the endemic Rinca rat (Rattus rintjanus), and fruit bats. One can also find goats, dogs and domestic cats.
Birds: One of the main bird species is the orange-footed scrub fowl (Megapodius reinwardti), a ground dwelling bird. In areas of savanna, 27 species were observed. Geopelia striata and Streptopelia chinensis were the most common species. In mixed deciduous habitat, 28 bird species were observed, and Philemon buceroides, Ducula aenea, and Zosterops chloris were the most common.


MARINE PHYSICAL ENVIRONMENT :
The marine area constitutes 67% of the Park. The open waters in the Park are between 100 and 200 m deep. The straits between Rinca and Flores and between Padar and Rinca, are relatively shallow (30 to 70 m deep), with strong tidal currents. The combination of strong currents, coral reefs and islets make navigation around the islands in Komodo National Park difficult and dangerous. Sheltered deep anchorage is available at the bay of Loh Liang on Komodo’s east coast, the South East coast of Padar, and the bays of Loh Kima and Loh Dasami on Rinca. In the North of the Park water temperature ranges between 25 – 29°C. In the middle, the temperature ranges between 24 and 28°C. The temperatures are lowest in the South, ranging from 22 – 28°C. Water salinity is about 34 ppt and the water is quite clear, although the waters closer to the islands are relatively more turbid.

MARINE ECOSYSTEMS :
Indonesia is the only equatorial region in the world where there is an exchange of marine flora and fauna between the Indian and Pacific oceans. Passages in Nusa Tenggara (formerly the Lesser Sunda Islands) between the Sunda and Sahul shelves allow movement between the Pacific and Indian oceans. The three main ecosystems in Komodo National Park are seagrass beds, coral reefs, and mangrove forests. The Park is probably a regular cetacean migration route.

MARINE FLORA :
The three major coastal marine plants are algae, seagrasses and mangrove trees. Algae are primitive plants, which do not have true roots, leaves or stems. An important reef-building algae is the red coralline algae, which actually secretes a hard limestone skeleton that can encrust and cement dead coral together. Seagrasses are modern plants that produce flowers, fruits and seeds for reproduction. As their name suggests, they generally look like large blades of grass growing underwater in sand near the shore. Thallasia sp. and Zastera spp. are the common species found in the Park. Mangroves trees can live in salty soil or water, and are found throughout the Park. An assessment of mangrove resources identified at least 19 species of true mangroves and several more species of mangrove associates within the Park's borders.

MARINE FAUNA :
Komodo National Park includes one of the world's richest marine environments. It consists of forams, cnidaria (includes over 260 species of reef building coral), sponges (70 species), ascidians, marine worms, mollusks, echinoderms, crustaceans, cartilaginous and bony fishes (over 1,000 species), marine reptiles, and marine mammals (dolphins, whales, and dugongs). Some notable species with high commercial value include sea cucumbers (Holothuria), Napoleon wrasse (Cheilinus undulatus), and groupers.

With this information, people can know how that komodo national park is interesting because the park can save many of knowledge of the world.
