Abstract:Population properties are presented of several plant species – dominants in psammophyte communities of low density, and changes in the specific composition and abundance structure of selected communities in the years 1968-1975. Communities with a coverage of 40-60% in the first study year were considered to be loose sods. The expansion of Tragopogon heterospermus Schweigg. and Carex arenaria L. was found to cause a considerable transformation of the phytocenotic relations of psammophyte communities. The two species have shown a great dynamism and competitive power. Populations of the following species have shown a relatively low sensitivity to the competitive action of T. heterospermus: Koeleria glauca (Schkuhr) DC. and Festuca psammophila (Hackel) Krajina. Irregular variations in the specific composition and population abundance of individual components were found in a patch of the association Corispermo-Plantaginetum indicae.
