| Summary: | <p align="justify">Private Forest has an important role in the socio-economic life of the community, as well as in the field of ecology, especially in environmental conservation. Community forest management is often carried out on sloping land, so it has the potential to erode. Continuous erosion will reduce land productivity. The Indonesian Ecolabeling Institute (LEI) developed a certification scheme for Sustainable Community Based Forest Management (PHBML) as a standard for sustainable forest management. Ecological aspects are one aspect of assessment in LEI certification. This study aims to determine the level of erosion hazard (TBE) and important value index (INP) of each level of vegetation living in the forest of Sawahdadap Village. In this study the determination of TBE and INP is based on three lands coverings (open, medium and closed) obtained from map interpretation using Arcgis Software. INP will show dominance or mastery of a type against other types in a community. Determination of TBE using the USLE (Universal Soil Loss Equation) method is a relationship between several factors, namely erosivity rain (R), soil erodibility (K), slope length and slope (LS), land cover factor (C), and soil conservation measures ( P). The results showed that the level of erosion in open, medium and closed land cover was 66.46 Tonha^(-1) year^(-1), 27.67 Tonha^(-1) year^(-1), and 14, 24 Tonha^(-1) year^(-1). TBE classes produced in open, middle and closed places are class III (medium), Class II (light) and Class I (normal) respectively. The highest IVI tree level was in the open, middle, and closed plots of the Mangifera indica (92.45%), Paraserianthes falcataria (144.29%) and Gmelina arborea (87.79%). The highest polar INP levels in open, medium and closed plots were Toona sinensis (213.20%), P. falcataria (233.55%), and G. arborea (203.33%). The highest STI levels in open, medium and closed plots were Maesopsis eminii (160%), P. falcataria (138.10%), and M.eminii (108.33%). The highest herbal levels and INP seeds in open, medium and closed land were Bidens pilosa (54%), B. pilosa (43.08%), and Setaria barbata (64.43%).<p align="justify"> |
