The comparison of restorated and successional areas from the point of view ofthe plant diversity - Suchdol sandpit lakes, Třeboň Basin Area

The Diploma´s thesis deals with the issue of comparison of recultivated areas and areas in the point of ecological succession from the viewpoint of the plant diversity of chosen hydro-ecosystems of Trebon basin, in the area of Suchdol nad Lužnicí. Mapped sandpits Cep, Cep I, Tušť a Františkov are situated in the flood plain of the river Lužnice. Local mining of sandy gravel started in 1950s and in some areas it has not finished until now. Every mining process leads to extensive damages of the landscape, which should be corrected. The aim of this thesis is to map and compare the areas on the coast of extracted sandpits where the recultivation was done with those which were left to "controlled" ecological succession
