AGRONOMIC EVALUATION OF THE FOREST AND LAND REHABILITATION IN BANGGO VILLAGE OF MANGGALEWA, DOMPU, INDONESIA

Abstract

Forest and land rehabilitation (“RHL”) is an effort to restore, maintain and improve forest and land functions, and to ensure that the implementation is in accordance with the plan, an evaluation is needed. This study aimed to evaluate the success of the forest and land rehabilitation efforts carried out in the RHL Banggo Village, Manggelewa District, Dompu Regency, Indonesia, by focusing activities on evaluating the success of land revegetation efforts using several types of plants (mahogany, candlenut, jackfruit and durian). This study applied an evaluation research method by conducting a direct observation survey in the RHL area located in Banggo Village for 4 months (October 2020 to January 2021). The plant evaluation was carried out based on the Regulation of the Minister of Environment and Forestry No P.105/MENLHK/SETJEN/KUM.1/12/2018. Based on the data collected, in general the forest and land rehabilitation effort in the Banggo location can be categorized as being successful based on the average growth percentage of all rehabilitation plants across evaluation plots (76.26%) or across species of the plants (76.25%), but one of the plant species, i.e. mahogany showed low growth percentage (57.5%). However, based on the percentage of plant health, the average across evaluation plots was low (56.22%). This could be due to the limiting environmental conditions in the Banggo location, which are dominated by clayey soil types with the land physiography is dominated slightly steep to very steep lands with a total area of 138 ha of the total area of 151 ha and low annual rainfall. To improve the success of the forest and land rehabilitation effort in the long-term in the future, better adapted plant species need to be found and tested locally.
