To address the concern of environmental loss, Bharat Coking Coal Ltd. (BCCL) Dhanbad and Forest Research Institute (FRI), Dehradun initiated restoration of Tetulmari coal mine. Restoration began in 2011 continued till 2014 and an ecological restoration model was developed in 8ha coal mined OB dumps at Tetulmari, Sijua area of Dhanbad to bring back life. Further, for attaining a more stable and sustainable ecosystem at the site, a biodiversity enhancement initiative was taken up by FRI in year 2016-2018 to develop aself sustaining ecosystem at the degraded site. Interventions such as weed eradication, mulching, top soil spread, pitcher irrigation technique were applied to create congenial conditions for plant establishment, survival and growth. In comparison to 58 species recorded in 2013-14, the restoration site in 2018 was observed to be enriched with a total of 103 plant species of which 37 are trees, 15 shrubs, 27 herbs, 9grasses, 2 bamboo, 2 fern, 1 creeper and 10 climber species. Occurrence of native species other than planted species such as Bombaxceiba, Ficus glauca, Ficus racemosusand Butea monosperma has shown that the ecologicallyrestored site have started facilitating the inflow of native species which was one of the mainaim of restoration programme.The enhanced biodiversity has facilitated occurrence of manyfaunal species of birds, butterflies, insects, reptiles and few of animals like foxes and rabbits,etc. have naturally recolonized or visiting at restored site. Results of this study suggest thatmining sites can be recovered and forests can be restored to a self-sustaining ecosystems, if appropriate managementstrategies are adopted.
