ABSTRACT
This chapter describes the combined efforts and activities of the Huai Thap Than and Ise communities to avoid the overexploitation of this unique native wild species that has become victim of its own commercial success. The chapter focuses on propagation techniques for G. fusca to explore the multiplication and domestication of this wild species. It also describes the participatory research activities conducted with the environmental group of the Ise community to explore additional products and cultivation techniques for wild madan. Wild madan is one of the wild relatives of the more popular fruit mangosteen. The tree, locally known as wild madan, is a medium-sized tree or shrub which grows abundantly and naturally along the Thap Than River and other riverbanks, streams and swamps. The good practice could also protect the Thap Than River banks from soil erosion phenomena. Wild madan saplings have been replanted along the river.
