Abstract

Sulawesi Island has the highest proportion of biodiversity and contains one of the most fascinating and unique flora and fauna. Diospyros celebica Bakh. is one of the Sulawesi^s endemic floras. This study aimed to describe the soil and geographical characteristics of D. celebica Bakh.^s site based on soil conditions, altitudes, geographic position, slopes, and land surface form. This study was carried out in the Protected Forest area of Amaro in Tuwung Village Barru District, Barru Regency, South Sulawesi, and in Silviculture Laboratory, Faculty of Forestry Hasanuddin University Makassar. The results revealed that conditions of soil properties in the study site were relatively more minor support of the growth of Ebony in all sub-populations, particularly the content of C-organic, N-total, and K that was very low to low. Altitudes on the four sub-populations in the study area were from 110 to 150 meters a.s.l. and were suitable for requirements of ebony growth. Slopes of each sub-population varied that sub-population of Tonrong Ceppie was relatively flat, while the sub-population of Deppanae wa s steep. No doubt that the growth rate of Ebony in the study area was affected by soil properties and site characteristics.
