Abstract

The paper deals with the flora of Chasnala mine complex including various dump sites. The survey of flora deals with enumeration of species, their life forms and dispersal types. It is evident that the dumps can acquire flora and advent of the species is contributed by flora of adjacent areas. The wind dispersed species are rich and the herbaceous species predominate initially. Chemophytes and hemicryptophytes have advantage in the pioneering stage. Grasses and legumes also appeared in the early successional stages.
