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 g...
Impact of mining on tree diversity of the silica mining forest area at Shankargarh, Allahabad, India
Journal of Forestry Research, 2011
The Shankargarh forest area is rich in silica, a major mineral used in glass industry. Extensive open cast silica mining has severely damaged the forest as well as productivity of the region. An understanding of the impact of mining on the environment particularly on vegetation characteristics is a prerequisite for further management of these mining sites, especially in the selection of species for reclamation works. The present paper deals with the study of the tree composition of silica mining area of Shgankargarh forest, at both disturbed and undisturbed sites. Tree vegetation study was conducted at undisturbed and disturbed sites of Shankargarh forests using standard quadrate method. Density, abundance and frequency values of tree species were calculated. Species were categorized into different classes according to their frequency. The importance value index (IVI) for each species was determined. Species diversity, Concentration of dominance, Species richness and Evenness index were calculated for the undisturbed and disturbed sites. The distribution pattern of the species was studied by using Whitford’s index. Similarity index between tree composition of disturbed and undisturbed sites was determined by using Jaccard’s and Sorenson’s index of similarity. Tree species showed a drastic reduction in their numbers in disturbed sites compared to that of the undisturbed sites. The phytosociological indices also illustrated the impact of mining on the tree composition of the area. The present study led to the conclusion that resultant tree vegetation analysis can be used as important tool for predicting the suitability of particular species for revegetating the mined areas.
Environmental impacts of mining on biodiversity of Angul -Talcher open mining site, Odisha, India
Biodiversity sustains human livelihoods and life itself. An estimated 40 per cent of the global economy is based on biological products and processes. As the biodiversity harbours a great amount of diversity with respect to species diversity, crop diversity, etc. which provides a rich amount of a well evolved system over time background support for rich resources. In Angul-Talcher area, in recent years, intervention of human activities has been very much noticed. Mining is on rise for last few decades in the area, covering huge belt of land and eventually also harming the forest cover of the Angul-Talcher forest division. Environmental Impact Assessment is a study of the effect of a proposed mining project, plan or program on the environment. The present paper attempts to reveal the base line environmental quality and socioeconomic setting in and around such mining sites with special reference to the effects on the biodiversity, air, water, changes of land use pattern and occupational health effects of mine workers etc.
EFFECT OF COAL MINING ON VEGETATION OF TALCHER AREA OF ODISHA, INDIA
International Journal of Modern Agriculture, 2020
Extensive coal mining activity in Talcher Coalfields of Angul district of Odisha has led to habitat degradation and a landscape dotted with mine spoils. The main aim of this study is to assess the impact of coal mining on vegetation of Talcher area. To make mining possible several forest are cleared and this leads to deforestation. The loss of vegetative land and forest land affects the vegetation of the area. Due to increase in energy consumption in India the mining of coal is also increasing causing more vegetation loss. Thus it is advisable that such activities have to strictly regulate and more plantation must done to keep control on loss of vegetation.

Mining is known to demolish adjacent natural ecosystem all over world with generating massive volumes of wastes dumped resulting in damage to the natural ecosystem, reducing herbaceous ground cover and wildlife. Hinustan Copper Mines (HCM) is the Asia's largest open cast copper mines and produces 70 % copper for the Indian market. The study was carried out at buffer zone of HCM in 31 forest sites of Birsha-Damoh forest range area of Balaghat district of Madhya Pradesh in India. The herbaceous ground cover (HGC) was estimated by line transect method. Results indicated that the total average herbaceous ground cover ranged from 11.2-77.44%, indicating least wildlife movement at site 14 and maximum at site 29. The dominant herbaceous plants were Cynodon dactylon followed by Lantana camara, Thysanolaena maxima covering across most of the sites. The rest of the herbaceous species were Vallaris heyne, Achyranthes aspera, Eragrostis tenella, Waltheria indica and Ocimum Gratissimum, found as casual constituents of the community. The maximum number (7) of wild animals presence in a day was observed at Cynodon dactylon and Thysanolena maxima dominated sites and minimum number (1) was observed at Lantana camera dominated forest sites.

Mining activities in Jajang iron and manganese ore mines located in Keonjhar district of Odisha, India starting from mineral explorations to production and transport are causing environmental damage in many ways, which includes deforestation, loss of topsoil, accelerated soil erosion, migration of wildlife and avifauna, and addition of air pollutants and dust to the atmosphere. In connection to this, the current study was an attempt to regain the original ecological status of the degraded areas of Jajang iron and manganese ore mines caused due to mining by Rungta Mines Limited. To achieve this indigenous plant species for restoration were selected from mining forests and plantations. Species selection from mining forests was made through systematic phytosociological analysis that involved measurement of Importance Value Index (IVI), regeneration values of tree species and their economic uses. On the other hand, species selection from plantations was made based on their growth, produ...
The Growth of Local Tree Species on Post-Coal Mining Areas in East Kalimantan
Indonesian Journal of Forestry Research
Post-coal mining areas need rehabilitation to restore its functionality. Not all plants could grow well on bare ex-coal mining area because of the excessive light intensity and extreme temperature fluctuations. This study is aimed to determine suitable local tree species for rehabilitating mined areas. Planting was carried out in November 2012, and observations were made in November 2015. The study site was in the district of Samboja, Kutai Kartanegara, East Kalimantan Province, Indonesia. Research results revealed that seven tree species survived well in the ex-coal mining land, i.e., Vitex pinnata L., Syzygium scortechinii (Merr.) Merr. & Perry, Syzygium polyanthum (Wight) Walp., Shorea balangeran (Korth.) Burck, Macaranga motleyana (Mull.Arg.) Mull.Arg., Cleistanthus myrianthus (Hassk.) Kurz and Syzygium lineatum (DC.) Merr. & L.M. Perry. From the seven species V. pinnata, Sy. scortechinii and Sy. polyanthum performed best in both survival and growth rates. This study suggests th...

The increase in the energy requirement of a country shows its economic advancement. Coal mining activity has increased considerably to compensate for the increased energy requirements. As a result, open-cast coal mining methods induced a drastic change in land use and seriously jeopardized the sustainability of the ecosystem. Once disrupted by open-cast or underground mining, the condition of the land cannot be entirely recovered, making it a non-renewable asset to the environment and support of human life. An attempt was made to study the existing flora of the different zones (operating, abandoned, control) of Charhi and Kuju Coal mining area, Jharkhand, India. From 2015 to 2018,173 species belonging to 75 families of angiosperms, terrestrial and aquatic ferns have been reported and identified so far from this study area. The most dominant family is Poaceae with the maximum number of species in the area, where mining has not yet been done. This paper's findings would help asses...

Mining activity causes a huge amount of land degradation by altering the land use pattern of the area. It is extremely difficult to restore and reclaim this degraded land because of the unfavourable Physico-Chemical conditions for plant growth. The purpose of the present study was the monitoring of land use and land cover, diversity and species composition of Gevra Opencast (OC) Mine of Korba Coalfield, Chhattisgarh and assessment of restoration success over the period of time. A phytosociological survey has been accompanied and a random quadrate sampling method was adopted for vegetation analysis and the change in vegetation cover was observed using Arc GIS software. The finding show that the area comprises 48 tree species with the Shannon-wiener index (H¢), Concentration of Dominance (D) (Simpson's index) Species Evenness (E) and species richness (R) were 2.72, 0.127, 0.70 and 6.38 respectively. A comparative analysis of land use and land cover based on data from 2001 and 2021 reveals that the degradation of agricultural land is caused by increased mining activities while similar efforts were made to restore the mine soil dump areas. NDVI value of the study site helps in monitoring the vegetation cover over a period which can be used as a monitoring tool for maintaining restoration success.
Tribal’s and their symbiotic relationship with forest and their surrounding environment has been seen from the ancient time. Their relationship with forest has crossed many centuries and forest maintained their existence until now. The nature of any type of new project in the forest area has negative and positive impacts and widen of these impacts can be minimal to significant in terms of biological environment and dependency of tribal habitat on the forest area. Therefore, mining operations essentially involves many significant impacts on deforestation, habitat destruction and biodiversity. Present study was based on study of biological environment and tribal habitat dependency on it in various sectors in the context of Ambaji Multimetal Mine project. Study of flora and fauna and tribal habitat was carried out to observe the interrelationship of these two.
