Phase dynamics of phytocoenosis on the damped waste heaps of Novovolyn mining area

Abstract

Nineteen non-recultivated waste heaps are found on the territory of the Novovolyn mining area (Lviv-Volyn coal basin), three of which are damping. The total area of disturbed lands is 116.7 hectares. An important role for optimization of disturbed objects is played by natural colonization by vegetation, since it indicates the state of the rocks the waste heaps are made of. Studying of phytocoenoses, which are formed during self-growth, gives an opportunity to estimate the formed groups, considering their place and role in the vegetation cover of the region and predict their further development. On the waste heaps, where combustion is stopped, the phytomelioration process develops in two ways: a) the formation of phytocenoses cultures with the part of wood species (robinia pseudoacacia, weeping birch, goat willow, Tartarian dogwood); b) natural colonization by zonal and synanthropic vegetation.
