THE EFFECTS OF INVASION BY CANADIAN GOLDENROD (SOLIDAGO CANADIAENSIS L.) ON FLORAL BIODIVERSITY IN LANDSCAPES TYPICAL FOR BELARUS

А.П. Гусев, Н.С. Шпилевская

Abstract


To assess the effects of S. canadensis invasion on floral biodiversity in Belarus, two series of geobotanical examinations in 2005–2006 and 2015–2017 were compared. In all plots, the projective cover with S. canadensis increased from 0–8 to 25–94%. These increases were associated with decreases in floral species diversity (the number and the abundance of species and coenotic diversity (the number of floral syntaxa), with the development of a homogenous cover consisting of S. canadensis communities, and with slowing down of succession. Projection cover areas negatively correlate with floral species diversity estimates (Spearmen correlation coefficient 0,64 at p less than 0,0001).
