Meadow species in the early stages of succession on the ash settler of power plant EDF Toruń SA in Toruń, Poland

Abstract

The paper is to present the trends of typical species of meadow habitats to colonize the frontier habitats. The area of research is the fly-ash landfills in the power plant EDF Torun SA in Torun. Several times, during the year mix of fly-ashes and slug, resulting from the combustion of coal, is transported by pipeline and this is mixed with water. Floristic research was conducted twice: in 2013 and 2015 year. Within an area of about 7 hectares 84 species of vascular plants (43 species in 2013 and 61 in 2015) were inventoried including 14 characteristic species of meadows. The presence of these species disturbed strong evidence of a wide ecological range and adaptations to survive adverse conditions of habitats. The results demonstrate that meadow species as Festuca arundinacea , Festuca rubra , Lolium perenne , Poa annua, Rumex acetosa and Taraxacum officinale, Poa trivialis and Viccia cracca can be helpful in restoration of fly-ash landfills.
