Indonesia Fauna

Wild Sumatran tiger numbers:

A total of 400 -- 500 Sumatran tigers (Panthera tigris sumatrae) remain in the wild. For the most part they live in five National Parks and two Game Reserves on the island, but about 100 are scattered in small widely-spread groups on land designated for agriculture. Their habitat is destined to be lost in the very near future.Sumatran tigers are distinctive for being the only subspecies to live in isolation on a large island -- Sumatra, Indonesia. They have been isolated from their cousins on mainland Asia for something like 10-12,000 years; this happened after a rise in sea level.

ORANG UTANS

About a million years ago, orangutans lived throughout much of Asia, from Java in the south, right up into Laos and southern China. Today they are found only on the islands of Borneo and Sumatra.Asia's only great ape, the orangutan has recently been re-classified as belonging to two distinct species, reflecting their geographical distribution: Pongo pygmaeus (on Borneo) and Pongo abelii (on Sumatra).

Under the IUCN (International Union for Conservation of Nature) Red List, the Sumatran orangutan is classified as critically endangered and thThe orang-utan is literally a "man of the woods", also called Mawas (pongo pygmaeus). It is a great ape with long reddish hair, and spends its time mostly moving about in the trees and less on the ground. Orang-utans live in the wet and hot forests of Sumatera and Kalimantan(Borneo). Kalimantan orang utans are red brown, while their Sumatran cousins are paler, and more gingerly color. Kalimantan orang utans also have coarser hair.
The mature male has fleshy cheekpads and a penduluos throat pouch, and his voice can be heard up to several kilometers away. His height reaches 125 cm standing tall, and weighs up to 110 kg. The female is about half in weight.

Orang utans have a varied diet of fruit, bark, leaves, and insects like ants, termites, and bees. They feed by moving in the canopy but the males freguently come to the ground to travel longer distances. However, the female of the species virtually never leave the trees. These creatures live a nomadic lifestyle depending on food availability. They have a solitary lifestyle unlike other species of monkeys or apes that live in groups.
The current number of orang utans left in the wild is estimated at between 20,000 and 27,000 (based on the latest survey comparisons between orangutan researchers in Sumatra in 1993). They are an endangered species, and are the only big ape found in Asia.e Bornean as endangered.

Indonesian Kopi Luwak

Coffee is a beverage, served hot or with ice, prepared from the roasted seeds of the coffee plant. These seeds are almost always called the coffee bean. It is one of the most popular beverages in adults today. The coffee bean, itself, contains chemicals which are mind-altering (in a way some find pleasing) to humans as a coincidental result of their defense mechanism; those chemicals are toxic in large doses, or even in their normal amount when consumed by many creatures which may otherwise have threatened the coffee beans in the wild. A coffee bean from two different places usually have distinctive characteristics such as flavor (flavor criteria includes terms such as "citrus-like" or "earthy"), caffeine content, body or mouthfeel, and acidity. These are dependent on the local environment where the coffee plants are grown, their method of process, and the genetic subspecies or varietal. Some well-known arabica coffee beans include: * Colombian - Coffee was first in...
