The Orang Rimba ('people of the forest') are a much smaller population of people (~3000) who live in the upstream regions of Jambi and South Sumatran. They have a unique, diverse economy, which shifts in and out of two base subsistence strategies: swidden farming and a very nomadic life based on foraging wild yams. This is traditionally combined with hunting, trapping, fishing, and the collection of forest products for trade. For many, part-time rubber tapping and participation in logging has gradually replaced the collection of forest products.
