Biomass partitioning in twoCalamagrostis villosa stands on deforested sites

Calamagrostis villosa stands occurring in areas deforested by air-pollution impact in the Moravian-Silesian Beskydy Mountains were characterized by a high dry mass of total underground biomass (3 300 g. m−2—the slope site, 2 850 g. m−2—the flat site). The percentage of living roots and rhizomes in total underground biomass was very high (about 70%). The total aboveground biomass was respectively, 321 g.m−2 (the slope site) and 726 g. m−2 (the flat site). In unstabilized habitats on steep slope, the higher plant biomass produced was allocated to a more developed root system.
