ABSTRACT
This chapter discusses how fruit trees and their species diversity have played a role in the local community towards contributing to their food, income and traditional uses and to know whether these species are being threatened due to the introduction of modern varieties. It also explains how the elderly population of the community keeps records of their traditional knowledge in order to maintain the cultivation of these species. Garcinia forbesii King is a lesser-known mangosteen that can be found in the wild in the lowland forests of the foothills of the Crocker Range, and as a semi-wild or cultivated fruit tree in home gardens and orchards in the district of Papar in the state of Sabah, Malaysia. Aroi aroi as a species is popular mainly among the Kadasandusun community of Papar and throughout the west coast of Sabah.
