Dvorščík, Petr ; Frouz, Jan (advisor) ; Cudlín, Pavel (referee)
This thesis has been elaborated as a part of complex succession research on the Velká podkrušnohorská spoil heap near Sokolov (north-west Bohemia, GPS: 50ř13'34.695"N, 12ř42'6.627"E) . The objective of this work is to describe biomass development of reclamational and successional localities on a chronosequence example. Unreclaimed areas are represented by successional spontaneous vegetation with dominant Goat willow (Salix caprea) with an mixture of European aspen (Populus tremula) and European birch (Betula pendula). Reclamation areas are represented by forest planting of Black alder (Alnus glutinosa) mixed with Grey alder (Alnus incana). On this localities was quantify total biomass (above and below ground biomass of herb and tree layer). Data evaluation was performed using allometric equations formed on destructive analysis of the main tree types. There is not statistically significant difference betwen the recovery site methods. Keywords: chronosequence, biomass, succession, reclamation, spoil-heap, allometric
