In the Philippines most dipterocarp forests have vanished due to logging shifting cultivation and transformation into settlements or agricultural fields. With an increasing interest for native tree species in land rehabilitation and reforestation the need to identify the still available species resources as well as their habitat preferences arises. I analysed vegetation data from the Leyte Cordillera on the island of Leyte Philippines to document the occurrence and habitat distribution of dipterocarp species. A total of 18 species belonging to the six Philippine dipterocarp genera and representing all eight Philippine dipterocarp timber groups were encountered. Distinct habitat distribution patterns and elevational ranges could be observed that could serve as baseline information for ensuring species-site suitability in local reforestation and tree plantation programs.

Les Dipterocarpaceae représentent la famille la plus importante d arbres d intérêt économique en Asie du Sud-Est. Aux Philippines la plupart des forêts à Dipterocarpaceae ont disparu sous les effets conjugués de l exploitation forestière de l agriculture itinérante et de l augmentation
