Vegetation Condition of Community-Managed Forests in Aik Bual Village and Setiling Village, Lombok Island

Abstract

Community-based forest management practices var y according to biophysical and management factors . This study aimed to explain the vegetation conditions of community-based forest manage ment in Aik B ual and S e tiling village , Lombok Tengah . The study site was divided into protected forest area s (HL) in Aik B ual Village with a legal community forest permit (Aik B ual-HKm), HL in S e tiling Village with no legal community forest permit (S e tiling- N on Permit), and HL in Aik B ual Village with no legal community forest permit (Aik B ual- N on Permit). Field measurement was conducted in Ju ly 2018 by establishing 12 plots of 20 m x 20 m . Each plot consisted of subplots of 10 m x 10 m, 5 m x 5 m , and 2 m x 2 m to collect data of woody and non-woody plants with the criteria of diameter (D) as follows: D ≥ 20 cm, 10 cm ≤  D < 20 cm, 2 cm ≤  D <10 cm, and D < 2 cm with tree height of < 1,5 m, respectively . The results showed that Aik B ual-HKm, S e tiling- N on Permit and Aik B ual- N on Permit had 24, 13 and 22 species , respectively . Dominant species of vegetation at D ≥ 20 cm were Erythrina variegata and Swietenia macrophylla , at 10 cm ≤  D < 20 cm were Musa paradisiaca and Durio zibethinus , at 2 cm ≤ D < 10 cm was Coffea canephora, and at D < 2 cm were C. canephora and S. macrophylla . Vegetation diversity index (H' ) of plants at D ≥  2 cm in Aik B ual-HKm was slightly higher (H'=1 , 78) than that in S e tiling- N on Permit (H ’ =1 , 04) and Aik B ual- N on Permit (H ’ =1 , 15) , although these are classified as moderate. The results illustrate d the possible differences of vegetation diversity in community-managed forest s with and without legal permission .
