Abstract
Establishment of Novel Ecosystems on Post-Mining Land in South Kalimantan, Indonesia.
Several coal mining activities in South Kalimantan have entered the post-operation stage and they are being prepared for submission to the government. All environmental management efforts have been undertaken in accordance with applicable standard procedures. To assess the level of post operation success of the mine was evaluated, with concentration on the aspects of flora, fauna, soil fertility and water quality. This research focuses on efforts to improve soil fertility by planting adaptive species of marginal land with low fertility. This evaluation used survey and sampling method using purposive sampling which was placed in every planting year from 2001 to 2006. From the survey results obtained that the quality of life of good crops with growth for fast growing species is normal and there has been a process of natural succession to the recovery. Soil fertility rate is relatively good with C-organic parameter, P2O5, K2O, CEC, and saturation base approaching secondary forest condition. Several species of birds and mammals have resumed, each about 10% of bird species and 12% of mammal species have returned. Post-mining land that has been planted with various types of fast growing species has formed a novel ecosystem that supports the formation of new secondary forests. Post-added land to recovery marked by the arrival of endemic species of plants and animals.
Keywords: reclamation, revegetation, succession, recovery, fertility
