All about Sumatran Elephant

I. Habitat

Elephant travels much within broad home range so that they need more than one type of habitat. Forest types suitable for Sumatran elephants based on research are:

1. Swamp forest
This forest type encompasses swamp grass land, primary swamp forest, or secondary swamp forest dominated by Gluta renghas, Campenosperma auriculata, C. Macrophylla, Alstonia spp, dan Eugeniaspp.

2. Peat Swamp Forest
Vegetation types in this forest type are: Gonystilus bancanus, Dyera costulata, Licuala spinosa, Shorea spp., Alstonia spp., and Eugenia spp.

3. Lowland forest
This forest type is located in the altitude of 0-750 m above sea level with dominant vegetation of Dipterocarpaceae family.

4. Lower mountain rain forest
This forest type is located in the altitude of 750-1,500 m above sea level with dominant vegetation of Altingia excelsa, Dipterocarpus spp., Shorea spp., Quercus spp., dan Castanopsis spp.
 

 II. Requirements to Live in Nature

1. Shelter 
Sumatran elephants are categorized as warm blooded animals thus in the hot weather condition, these animals will find shelter (thermal cover) to stabilize their body temperature to fit with the environment temperature. The locations usually used for shelter and rest at day light are the places covered with dense vegetation.

2. Diet
Sumatran Elephants are also categorized as herbivorous animals so that they need green food available sufficiently in their habitat. Elephants also need habitat with tree vegetation for their supplement in fulfilling the need for calcium mineral in order to strengthen their bone, teeth, and ivory. Since the digest system is less perfect, an adult elephant needs food in a big amount between 200-300 kg biomass per day or 5-10% of its body weight.

Sumatran elephant food types in natural habitat comprises of some kinds of wild herb, liana, tree bark, banana, and young leaves. If they invade paddy field or farming land, elephants will eat paddy, sugar cane, young coconut leaves, fruit such as papaya, and other seedlings.

3. Water 
Elephants are very much dependent to water thus in the afternoon they look for water sources for drinking, bathing and wallowing. A Sumatran elephant needs to drink about 20-50liter/day. When the water sources are dried, elephant can dig for 50-100 cm using his front feet and trunk in search of water.

4. Mineral 
Elephant also needs mineral salt such as: calcium, magnesium, and callium. These minerals are licked by consuming soil heap contained salt, loosing the hard slope by its front leg and trunks, and eating while raining or after raining.

5. Home range
Elephant is the biggest land mammal that still exist in this age thus it needs wide home range. The Asian Elephant home range is varied between 32.4 - 166.9 km2 meanwhile the home range of elephant herd in primary forest is twice bigger than that of in secondary forest. This condition is related to food productivity in these two different forest conditions.

6. Security and comfort
Elephant needs secured and comfortable situation so that breeding habit will not be disturbed and production process will work well. Therefore wood felling activities done by concession companies have disturbed security and comfort for elephants.
