Climbing a tree is a universal joy while growing up and constructing a tree house is a further source of fun, especially as an exclusive meeting place barring adults. Schemes for alien defense, gender battles and plots for world domination are often hatched, until we are told to come down or grow up, or when such an abode no longer inspires our imagination.
However, there are some people who are never told to grow up and climb down, and for whom the tree is an endless source of joy, shelter and essential part of family life. These people are the Korowai and Kombai tribes who live in the dense forest of West Papua in Indonesia, and until 1975 had hardly any contact with the outside world. A large portion of their life is spent 20 to 40 metres above ground in tree houses, and on notable occasions eating the nutritious delicacies of sago grubs.
The tree houses are constructed relatively quickly and provide a good defense against warring tribes, floods and biting insects. The pig is the local currency and a sacred animal, while ritual cannabilism was apparently practiced more in the past. However, once dead, the Korowai believe their souls travel to the underworld along a ‘Major Causeway’ and are welcomed by their ancestors. After a while there they can choose to reincarnate back into a child that is about to be born.
Constructing a tree house is begun by choosing a sturdy Banyan tree and then removing the crown. Thinner poles provide the framework while the bark of the sago palm is used for the floor and walls, and leaves provide roofing. Similar to most cultures, marriage normally initiates a new house.
For these two tribes, the tree is far more than a provision of shade and beauty, but a home and a source of comfort. Contact has been growing with the outside world, but I imagine there would be some confusion when describing current rates of deforestation and the behaviour of more ‘civilised’ humans.
