Along the Phra Prong River (Sa Kaeo Province, eastern Thailand), the riparian vegetation community has large trees scattered along the river bank. [3] The common taxa are Hydnocarpus castaneus , this species, Dipterocarpus alatus , and Crateva magna . They show low natural regeneration, with few saplings and seedling. The two species, H. castaneus and X. lanceatum do show strong tolerance for flooding. [6] Seedlings of the two taxa showed no elongation or biomass suppression, and adventitious roots were found. This indicates that they may play a strong role in vegetation restoration. Elsewhere on the river is the Bodhivijjalaya College campus of Srinakharinwirot University. The riparian forest associated with this campus has the following trees: H. castaneus, Garuga pinnata , C. magna, Hopea odorata , D. alatus, Streblus asper , Knema globularia , Nauclea orientalis , and X. lanceatum.
