Abstract:
Shorea balangeran korth species belong to the Meranti Group which is community
found in swamp forest or Kerangas Forest. S. Balangeran tree can also grow in open fields such as grass fields. The S. balangeran korth species grow relatively fast compared to other peat swamp plant species and the wood has a good adaptation but it plant and species still has limitations in very marginal land conditions. The objectives of this study are: i) to analyze the composition of the
vegetation around S. balangeran in Taman Hutan Raya (Tahura) Sultan Adam Mandiangin. ii) to analyze the habitat characteristics of S. balangeran. Data processing analysis used vegetation analysis by using the value of the important index (INP) and the diversity index of Shanon_Wiener. The results of the study showed the composition of the species of seedlings around S. balangeran consisted of 16 species, the sapling level consisted of 15 species, the pole level consisted of 7 species and at the tree level consisted of 7 species. The S. balangeran species in the Sultan Adam Mandiangin TAHURA area was the dominant species
