The Wana are also distinguished by concurrently burning swiddens and repeatedly firing poorly burned areas. The Wana intercrop Orzya spp. Fruit trees are rarely planted in swiddens. Thus, fallow management is minimal. Younger and older house gardens are more diverse than intermediate gardens due to the presence of fruit trees in the former and dominance of Manihot esculenta in the latter.
House gardens are more diverse than swiddens.
Edible wild plants are gathered yet cultivated plants are preferred. Recent governmental efforts to settle the Wana in lowland villages have been largely unsuccessful. However, a few populations, including this study group, have become less mobile, resulting in some deleterious effects on the surrounding forest community.
