Production capacity of biomass of the floodpain community of Salix alba L. in southern Moravia

Abstract

The paper deals with the study of the production capacity of biomass in the seven-year stand of Salix alba L. The communities originated in the process of primary succession in the area of the middle Nové Mlýny reservoir on a newly established island. Already since the first stages, the communities have been monitored. Results have shown that white willow behaves as an R-strategist with fast growth in youth. Moreover, the growth is supported by optimum environmental conditions (soils richly supplied with nutrients and water, long growing season). Accumulated phytomass amounted 102,7 t.ha−1 at the age of 7 years and the yield reached a mean annual increment of 15 t.ha−1.year−1. Communities of white willow rank among highly productive phytocoenoses capable of fixing considerable amounts of carbon and, at the same time fulfilling the function of habitat corridors.
