Rice, raised in swiddens, is the staple; corn, yams, pumpkins, cucumbers, and tobacco are also raised. In some Kenyah groups, rice cultivation is controlled by women. Fishing, which is more important to the diet than is hunting, is accomplished primarily by poisoning with tuba root. Hunting is mainly done with dogs and blowguns, and the most important game is the wild pig. Goats, dogs, pigs, and chickens are raised domestically, the latter two for sacrifice. The Kenyah and Kayan are skilled woodworkers, metalworkers, and canoe builders. They trade their knives and swords, which are famous throughout central Borneo. For the Kenyah, rubber has become the most important cash crop. A Kayan individual who clears primary forest land has undisputed ownership of it.
