Urban forest in Indonesia can only be declared if it has been approved by the competent authorities in accordance with Goverment Regulation PP No. 63/2002. Therefore, it is necessary to evaluate the diversity of plant species in the urban forest. The purpose of this study is to analyze the plant diversity in the urban forest, and to analyze the physical condition of the urban forest’s trees. This study was conducted in three selected urban forest in DKI Jakarta, i.e. Indonesian University (UI), Srengseng and PT. JIEP. Vegetation Analysis and Shannon Wiener Index were used as a method for analyzing the plant diversity. In this study, the physical condition of the trees also were observed by scoring the physical criterias of the existing tree condition. Result for this analysis were used as input to urban forest management recommendations using SWOT analysis. The result showed that the diversity of tree species in three selected urban forest is moderate (1 < H’ < 3). Indigenous species in UI and PT. JIEP predominant were found than in Srengseng urban forest. While the physical condition of trees in PT. JIEP urban forest have the highest levels of damage compared to the other two urban forest. Suitability of ecological functions of trees examined by urban forest type, shows that PT. JIEP Urban Forest as a buffer for industry region has only 30% of trees that have either category as absorbing gaseous pollutants. While the UI Urban Forest and the Srengseng Urban Forest, ecological functions of trees based on the type of urban forest have been appropriate for the city to provide comfort for visitors. Recommendations of Urban forest management are produced from SWOT analysis. It is resulted 10 recommendations for trees biodiversity conservation in urban forest based on internal factor and external factor of the three selected urban forest in DKI Jakarta.
