Analysis of NDVI and Plant Vegetation Diversity in the Traditional Zone, Mount Halimun Salak National Park, Bogor

Abstract

Mount Halimun Salak National Park (MHSNP) traditional zone is a zone which is highly utilized by the local community to fulfill their daily needs by utilizing non-timber forest resources and implementing an agroforestry system with the main commodity is poh-pohan (Pilea melastomoides). Forest monitoring in the MHSNP traditional zone is very important to do as part of sustainable forest management and the realization of supporting Indonesia's Forestry And Other Land Use (FOLU) Net Sink 2030 program. This study aims to analyze the density of vegetation based on NDVI values; besides, analyze the level of plant species diversity and stand structure in the traditional zone of MHSNP. Furthermore, the data collection of plant species diversity at the area based on NDVI value of vegetation density. NDVI values ​​are obtained into three classes that have different land conditions. The class 1 value range from 0.147 to 0.273 has a low vegetation density. Class 2 from 0.273 to 0.319 has medium vegetation density. Meanwhile, class 3 has high vegetation density with a value of 0.319 to 0.433. Diversity of plant species has 60 different species from a total of three classes. The density of seedlings is lower than saplings and at the level of poles, trees is decreasing that is indicates a balanced stand structure. The low seedling level is caused by inhibition of seedling growth due to cleaning by the local community in preparation for planting understory since the community prefers to plant understory which harvest faster woody plant seedling.
