The objectives of this research were (1) to identify population of jelutung in Harapan Rain Forest-PT Restorasi Ekosistem Indonesia (HRF-PT REKI), (2) to analyze habitat characteristics of D. costulata on HRF. The study was conducted in May-June 2015 at HRF-PT REKI, Batanghari District, Jambi. Data were collected by interview and vegetation analysis with sample plot of 2 ha. Result this study showed, D. costulata stand condition in HRF was abnormal.

But, species richness around habitat jelutung a relatively high. In conclussion jelutungs of the study could be used to local conservation and management for sustainable used.
