From to , the Conservancy collaborated with 19 other NGOs to conduct a quick ground survey — primarily counting orangutan nests, since the apes themselves can be difficult to spot — and interviewing community members from villages. From this work, it was determined that a staggering 78 percent of the orangutan population in Kalimantan lives outside protected areas.
Unprotected lands in this region are often subject to both legal and illegal logging. Conservationists also work with these companies to develop practices to conserve orangutans so that the large landscape outside protected areas can continue to provide a home for orangutans. Working with forestry and palm oil companies to test and implement land management practices that lessen impacts to forest habitat and reduce carbon emissions while maintaining profits.
Providing tools for local communities to work with governments to protect their village forests. Assisting communities to develop forest-friendly livelihoods such as sustainable agriculture and sale of forest products like honey. You can help too. The only way for orangutans to avoid extinction is for people like you to intervene, take action, and encourage others to act. Orangutans have the slowest known life histories of any mammal. They take the longest time to grow up and they are the slowest to reproduce.
The gestation period is approximately eight and a half months. Twinning occurs but is rare. In forty years of observation, twins were only seen once at Tanjung Puting National Park. The mother was an older, free-ranging, wild born ex-captive orangutan.
One of the twins was born weak and died shortly after birth. Wild female orangutans usually become sexually active at approximately 12 years, but they will often have their first offspring only at years of age. At Tanjung Puting wild females give birth on average every 7. Infant orangutans stay in close contact with their mothers for a long time. They also use leafy branches to shelter themselves from rain and sun, and sometimes even drape large leaves over themselves like a poncho.
Orangutan offspring will sometimes be carried until they are 5 years old and be breast-fed until they are 8 years of age! Even when young orangutans are too old to be carried and fed by their mother, they may still remain close to her, traveling with her, eating, and resting in the same trees, until they are about 10 years old. Once they become independent, they will be alone or in the company of other immature orangutans. Such prolonged association between mother and offspring is rare among mammals.
Probably only humans have a more intensive relationship with their mothers. Young orangutans learn almost everything from their mothers, including: where to find food, what to eat and how to eat it sometimes this involves using special tools , and how to build a proper sleeping nest.
Also, mothers probably protect young orangutans from predators such as clouded leopards and pythons in Borneo, and tigers in Sumatra. A flanged male has big cheek pads on the sides of his face and a large pendulous throat sack under his chin.
An unflanged male has neither of these traits, and his body is usually smaller. Unflanged males are sexually mature and fully able to father offspring; females, however, seem to prefer to mate with the flanged males.
It is not fully understood exactly when and why a mature male undergoes the transformation from unflanged to flanged, or even if every male undergoes this transformation although it seems likely that he does eventually. Thus, not until the dominant flanged male dies, moves away, or is defeated, or the subadult male himself moves away or stays low, can the unflanged male develop his cheek pads and large size.
Sound like a challenge? Whether you want to run a marathon yeesh! This year I was lucky enough to join a fantastic project in an area of restored rainforest in East Kalimantan, Borneo.
We all love setting the world to rights down the pub with our mates. So why not chew the fat about something truly meaningful?
