Abstract

Autecological research of Shorea hopeifolia (F. Heim) Symington was done at Resort Pemerihan, National Park of South Bukit Barisan, Lampung in November 2014. The data was collected using a square plot of 20 m x 20 m, number of sample units made was three plots and each plot was made to four subplots with the distance of 50 m between the subplots, distance between the plots was 2,000 m. The results showed that S. hopeifolia was found at altitudes above 260 m asl, alongside of the hill with a rather steep topography and groups. Vegetation encountered in the surrounding consisted of Dipterocarpus kunstleri King. with IVI of 28.89%, Shorea ovalis Blume with IVI of 18.83% and Lithocarpus elegans Blume with IVI of 15.06%. The physical environment temperature was between 25–35°C, humidity was between 52–76%, slope was between 15–65%, and altitude from sea level was between 276 to 350 m. D. kunstleri King. associated with the most powerful S. hopeifolia (close to 1) Ochiai index of 0.81, followed by S. ovalis Blume Ochiai index of 0.65 and Dillenia excelsa (Jack) Gilg. Ochiai index 0.52. Natural regeneration was assisted by wildlife especially hornbill (Buceros rhinoceros) and the flow of rain water.
