Migrants are often constrained by a lack of knowledge regarding their new environment and require new skills for their livelihood. In Palawan, some of these necessary skills and knowledge are related to the collection and use of non-wood forest products (NWFPs), many of which the migrants were previously not familiar with. The predominantly Visayan migrants have been successful in familiarizing themselves with the NWFPs in the surrounding forests, with assistance from some of the local indigenous people, in this case the Tagbanua, and from previous migrant settlers. The NWFPs they know about and the extent of use are presented. Currently, except for almaciga (Agathis philippinensis Warb.) resin and house-building materials, NWFPs are considered as supplements to agricultural products, not as main source of either subsistence or income.
