The Effect of Changes in Forest Area Designation on a Diversity of Undergrowth Vegetation

Abstract

Biodiversity is a term used for the degree of diversity of living natural resources, including the number and abundance of genes, species, and ecosystems in an area. Consists of various forms of life, their ecological role, and the diversity of germplasm contained therein. The purpose of this study was to examine the effect of changes in forest area designation on the diversity of understorey species. Data analysis used the method of placing plots in the lane using the plotted path method, with a plot area of 2 m x 2 m, by recording all understorey plants from sprouts to a seedling height of no more than 1.5 m. And also using the analysis of the important value index (INP) and species diversity. The results obtained from this study can be concluded that the species diversity in plantation forests is 3.470, in protected areas is 3.525 and in natural forests is 3.093. This shows that there is no serious effect on plant species diversity because the species diversity obtained shows results that are not much different between plantation forests, protected areas, and natural forests.
