Most of the knowledge on the usage of plants has unfortunately not been recorded. It is tend to be handed down from generation by word of mouth. In this respect, oral history and the collection and recording of ethnobotanical knowledge is of the utmost importance before this knowledge on the utilisation of plants is lost to posterity. Wild plants are part of virtually every daily meal, and the built setting of everyday community life, the houses, farm huts, boats, house furnishing, and tools, are all constructed of materials taken largely from the surrounding forest. Local communities have always had an interest in conserving a species-rich environment by creating a variegated landscape of open fields and closed forest in various stages of regeneration.
Changes is obviously inevitable, but without access to forested areas, traditional subsistence strategies are unsustainable and in the face of competing demands, are likely to fail, exposing rural people to possible malnutrition and declining living standard. Local ethnobotanical knowledge is immensely valuable legacy. Today, in Sarawak, this legacy is being lost, creating an enormous urgency for further studies which need to be conducted within a few years. By next ten years, will probably be the ‘last call’ for conducting comprehensive reference studies on the ethnobotanical knowledge of traditional communities in Sarawak. Modernisation and globalization penetrate further and further into previously isolated communities.
