Orangutans

[DawnDawn]

What’s so special about an orangutan?
Their eyes hold a story that is indecipherable and yet intuitively we relate to them. Just one look into those eyes and you are hooked.Orangutans are highly intelligent with an ability to reason and think. This large, gentle red ape is one of our closest relatives, sharing 97% of the same DNA as humans. Indigenous peoples of Indonesia and Malaysia call this ape "Orang Hutan" literally translating into English as "People of the Forest". In times past they would not kill them because they felt the orangutan was simply a person hiding in the trees, trying to avoid having to go to work or become a slave.
Orangutans are unique in the ape world. There are four kinds of great apes: gorillas, chimpanzees, bonobos and orangutans. Only the orangutan comes from Asia; the others all come from Africa. There are two separate species of orangutan - the Sumatran orangutan (Pongo abelii) and the Bornean orangutan (Pongo pygmaeus)
Orangutans are only found on the islands of Sumatra and Borneo
The orangutan is the only strictly arboreal ape and is actually the largest tree living mammal in the world. The rest of the apes do climb and build sleeping nests in the trees, but are primarily terrestrial (spending their lives on the ground). Even the hair color of the orangutan, a bright reddish brown, is unique in the ape world. The orangutan has the most remarkable ability to travel through the forest treetops. They make their home in these trees and build nests each night out of leaves and branches in the very tops of the trees.
This is where they live and sleep - sometimes as much as 100 feet above the ground. The orangutan has little need to come down from the trees, as they are uniquely adapted for their arboreal lifestyle. orangutans have unique adaptations to their life in the treetops: feet designed much like hands for climbing long arms for reaching and long, strong hands and feet flexible hips for holding on in any direction
Almost all of the food they eat grows in the treetops and the frequent rains fill the leaves thus supplying their drinking water. When water is difficult to get, they chew leaves to make a sponge to soak up water in tree cavities. When it rains very hard the orangutan makes an umbrella for himself out of big leaves. Many people are familiar with the studies that have shown chimpanzees using tools, such as termite-fishing sticks. Recent studies show that some populations of orangutans also fashion tools to aid in the difficult task of foraging for food.
Some might say orangutans have four hands instead of two hands and two feet. This makes them graceful and agile while climbing through the trees but it makes walking on the ground somewhat slow and awkward. That is why the orangutan is at a great disadvantage on the ground, and why the orangutan rarely comes down from the treetops. Their food is there, their home is there and they are safer there.
An orangutan's lifespan is about 35-40 years in the wild, and sometimes into the 50's in captivity. They reach puberty at about 8 years of age, but a female isn't ready for her own baby until she's in her teens.
Mother and baby The orangutan has the longest childhood dependence on the mother of any animal in the world, because there is so much for a young orangutan to learn in order to survive. The babies nurse until they are about six years of age. The young males may stay close by their mothers for a few more years but the females may stay until they are into their teens, allowing them to observe mothering skills as they watch their younger sibling being raised by the mother. Orangutan females only give birth about once every 8 years - the longest time between births of any mammal on earth. (This results in only 4 to 5 babies in her lifetime.) This is why orangutan populations are very slow to recover from disturbance.
Food is often scarce in the rain forest and that is why the orangutan is a semi-solitary creature. In times of great abundance of food, orangutans may use the opportunity to socialize and gather in small groups.
In the trees their diet is made up of bark, leaves, flowers, a variety of insects, and most importantly, over 300 kinds of fruit. The mothers must teach the babies what food to eat, where to find that food, in which trees and during which seasons. It is thought that the orangutan must have a very detailed map of the forest in her mind, and detailed knowledge of the fruiting cycles of many species of trees. (This prevents wasting valuable energy searching for fruit trees randomly, and traveling to a certain fruiting tree whose fruits will not ripen for some time). The babies must eventually know hundreds of species of plants and trees, which ones are edible, and how to process them; some are very difficult to eat because they are protected by sharp spines and shells.
The throat sac is used to make a very notable and recognizable call that echoes through the forest. This is called the " Long Call" and is used to locate and advertise their presence to females or warn other males away.
Males often weigh over 200 pounds, where females are 1/3 to 1/2 his size
The males generally remain solitary until they encounter a female who is receptive to mating. They will stay with the female for several days to ensure a successful mating but will soon resume their solitary life. Due to their large size, males will more often travel on the ground than females.
Orangutans are one of the most critically endangered of the great apes, due to poaching and habitat loss. Based on the World Bank’s estimation that mechanized logging in the Kalimantan forest, (Indonesian Borneo), will result in its total loss by 2010, and other statistics stating that wild orangutans are disappearing at a rate of 2,000 orangutans per year, optimistic predictions give the orangutan ten more years before extinction in the wild

While you are reading this one of the last safe havens for Orangutans is being destroyed! If the current rate of forest destruction continues, this remarkable species is predicted to be extinct in the wild within the next decade! Orangutans are restricted to the rainforests of Borneo and Sumatra in South East Asia. These forests are now being heavily impacted by logging to supply the demand for hardwood products in Asian, European and American countries. As a result of this and other pressures, Orangutan numbers have fallen by 50% in the last decade and only about 20 000 are estimated to remain. Until very recently Gunung Palung National Park in West Kalimantan, Indonesia, was a beautiful and secure rainforest oasis that harbored an incredible 15% of the world’s remaining Orangutans. This situation has now changed, and it’s getting worse very quickly. Today, deep within what were once the safe borders of this Park, one is confronted by the sights and sounds of chainsaws and numerous illegal logging teams. Previously tranquil rivers are cluttered with a ceaseless procession of logging-rafts.
Due to conflicting interests, local and regional authorities seem unable or unwilling to halt these destructive activities. As money from wood sales tends to go to foreign companies, illegal logging represents a major loss of revenue for Indonesia. Although the individuals who join dangerous illegal logging teams are provided with a basic income, this has to be weighed against the long-term costs to communities that must cope with flooded rice fields, declining fish stocks, reduced availability of safe drinking water, and loss of income from non-timber forest products such as rattan and fruit. If Gunung Palung National Park is destroyed, villagers will also loose the greatest chance they had to develop a local eco-tourism industry.
Is there any hope? We believe there is. Recent surveys found that almost 2000 orangutans still persist within the borders of the Park, and more in the damaged forests beyond - so it's not too late! If you agree with us that Gunung Palung National Park is too precious to be lost - please spread this message by sending it on to your friends and colleagues! Your participation could directly contribute to the preservation of an entire national park and one of the world's most endangered primates. We do not have much time so please don't hesitate! We need to remind those with the power to do something that protection of these remaining havens is of high priority both nationally and globally.
