Impact of Mining on Forests and Its Biological Diversity at Kirandul Iron Ore Mines, Dantewada, South Bastar, Chhattisgarh: A Case Study

Saroni Biswas, Anirban Biswas


Mining activities have several impacts on the environment. In our study, emphasis was given to assess biodiversity in one of the leading iron ore mining sites of Bailadila-Kirandul Iron Ore Mines (KIOM) of Dantewada District, South Bastar of Chhattisgarh. Habitat fragmentation, loss and deforestation are highly prevalent in the area. However, the study reveals high species richness of 110 and 253 plant species in core and buffer zone respectively. Canopy cover was found to be within 10 to 40% and in places in the buffer zone canopy cover with > 40% was recorded. Species diversity index indicates the instability of vegetation structure in the area with indices of 1.44 in core and 1.88 in buffer zone. Although species richness is high, about 10 floral species (7 herbs, 3 trees) are recorded under REET (Rare Endangered Extinct Threatened) species while locally endangered floral species are 6 and locally critically endangered are 4. Similarly, 208 faunal species belong to 10 faunal groups was recorded out of which 34 species are listed in different Schedules of Indian Wildlife (Protection) Act, 1972. Therefore, it is an urgent need for planning to undertake appropriate management strategies to conserve biodiversity in the area.
