Abstract
Fly ash is the major waste products of industrial plants that pose serious environmental hazards. Proliferation of fly ash deposits and its toxicity have become a global concern, which contaminate the ecosystems of our Earth. The present work was undertaken to study the Phytodiversity of potential plant species that naturally grow on fly ash deposits and quantitatively evaluate their sustainable phytorestoration potentiality. An intensive survey of vegetation was conducted during 2014-2015 in fly ash deposit of NALCO, Koraput, India. In this study 30 plant species were identified which are distributed in 28 genera belonging to 14 different families. Most of the plant species observed belonged to family Asteraceae followed by Poaceae and Fabaceae and 7 species are shrubs and 23 species are herbs. The plant species having phytorestoration potentiality in fly ash deposits were identified on the basis of their frequency, density, dominance and important value index at the study sites. From the study it is evident that species like Ageratum conyzoides, Alternanthera sessilis, Mimosa pudica, Perotis indica, Blumea lacera, Aristida setacea, Calotropis gigantea, Centella asiatica, and Crotalaria striata are potential plant species having fly ash deposits’ restoration potentiality. Furthermore, the naturally colonized species can be used for the phyto-restoration during a re-vegetation plan of new fly ash deposits. This may be used as an easiest, cost-effective and eco-friendly means of phytorestoration.
