%X Jungle rubber is a traditional multi-strata agroforestry system in which rubber trees grow together with secondary forest, timber and fruit tree species. The system provides a diverse range of timber and non-timber forest products, and environmental benefits due to its forest-like structure, but rubber production per hectare is low.
