Andongrejo Village is one of the buffer villages of Meru Betiri National Park (TNMB). The lack of baseline data related to the diversity of vegetation in agroforestry system surrounding TNMB requires further research as a conservation effort and sustainable ecosystem management purpose. The objectives of this research were to: (a) analyze the structure and composition of vegetation in agroforestry system, (b) analyze the diversity of vegetation in agroforestry system, as well as (c) analyze correlation of canopy density with the diversity of seedlings and understorey in agroforestry system in Andongrejo village, Jember Regency, East Java. The method used was purposive vegetation sampling and vegetation analysis. The number of individual (ind/ha) in all three canopy density classes did not show reverse J-curve. The dominant species found were Banana ( Musa sp.), Teak ( Tectona grandis ), and Sengon ( Paraserianthes falcataria ). The species richness and diversity index at all tree level growth were clasified into low diversity and low species richness. The higher percentage of canopy density results in the higher individuals per ha and the number of species per ha (r = 0.500 and r = 0.696). The implementation of enrichment planting with species that has high economic value at all tree level growth are necessary. Introducing fruit species is one of alternative ways to increase the local community’s income and conserve the diversity in agroforestry system. Silviculture technique (eg prunning) is necessary to maintain the diversity and tree level growth in this location.
