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.
