COMPOSITION AND DIVERSITY OF VEGETATION TYPES IN BURNED PEATLANDS AT HABARING HURUNG RESORT IN SEBANGAU NATIONAL PARK, CENTRAL KALIMANTAN

Abstract

Forest and land fires can alter the habitat characteristics, leading to a significant decrease in the number of microorganisms due to direct impacts on population and soil organisms’ mortality. Vegetation composition refers to the arrangement and collection of plants, including trees and shrubs that coexist and interact with each other to form an ecosystem. This research aims to investigate plant species diversity in both burnt and unburnt areas of Hubaring Hurung Sebangau National Park in 2015. The findings reveal that the highest species diversity (H') was recorded in unburnt peat depths of 50-<100 cm at the sapling level, with a value of 2.50. The highest Species Richness Index (R) was observed at the tree level, with a value of 2.89 in unburnt locations with peat depths of 100-<200 cm. The highest Evenness Index (E) was found at the pole level, with a value of 0.93 in unburnt locations with peat depths of 50-<100 cm.
