Solidago canadensis impacts on tillable land withdrawn from the farming turnover

Abstract

Solidago canadensis is the extremely aggressive alien species. Our study aimed to monitor the invasiveness of S. canadensis in the abandoned lands. The parameters characterizing its invasiveness (average shoot length, foliage projective cover, average number of vegetative shoots, average number of generative shoots in S. canadensis and the average number of associated species at the plots) were measured at two plant communities of the abandoned lands. According to our results, the invasion reduced the native plant species richness throughout 2016 and 2018. Therefore, the invasion of this species diverts of the vegetation succession, alters the mutual links between the native elements of these old fields.
