Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 7, Issue 6
Abstract
This research was aimed to assess the soil and vegetation structure in reclamation post-mining coal area of Banjar Regency, South Kalimantan, Indonesia. This study was conducted in ex-mining coal site of Regional Government Company Baramarta, Banjar Regency, South Kalimantan. Data was collected by field observation, lab analysis and documentation. Plot areas for the vegetation data were used transect method with size 40 × 25 m. Plot 20 × 20 m for trees, 5 × 5 m for stake and 2 × 2 m for seedling. Important value index was used for vegetation analysis which encompasses relative density, relative frequency, and relative dominance. Soil sampling was taken compositely for 50 g to be analyzed further in the laboratory to assess its physical and chemical characteristic. Total of 10 sites was sampled i.e. 4 natural soil sites, 3 reclaimed soil sites, and 3 sites of unreclaimed soil. Standard criteria to determine the soil damage was referred to the Government Regulation No. 150 of 2000 and the Ministry of Environment Regulation No. 7 of 2006. The highest Important Value Index (IVI) for trees and poles was Mahang (Macaranga gigantea), bamboo (Bamboosa sp) for stakes and ferns (Cyclosorus sp dan Geichenia sp) for ground surface plants. The results showed different physical and chemical characteristic between natural area, reclaimed and unreclaimed area, which implied that the reclamation activities improved chemical characteristic of the soil. The status of soil damage in Baramarta ex-mining site is categorized as damaged, due to its degree of water released that exceeds critical threshold. Different physical and chemical characteristic between natural area, reclaimed and unreclaimed area implied that the reclamation activities improved the chemical characteristic of the soil.
