Fresh lands cleared by each Dayak family will belong to that family and the longhouse community can also use the land with permission from the owning family. Usually, in one riverine system, a special tract of land is reserved for the use by the community itself to get natural supplies of wood, rattan, and other wild plants which are necessary for building houses, boats, coffins, and other living purposes, and also to leave living space for wild animals which is a source of meat.
