Fig. 5: The social behavior types according to group mass

we examine the group mass rate cosmopolitans’ participation is 70% taking into consideration that the presence of adventives is also remarkable due to the dominant Inula helenium. The aggressive neophyte plants may effect as a possible danger to the association namely the low rate presence of Ambrosia artemisiifolia and the Solidago gigantea may increase significantly.

Phytosociological groups

Regarding their mass the Molinio-Arrhenatheretea class allocates the characteristic features of the association (Fig. 3). Beside them the resettling elements of the forests (Querco-Fagetea) from the edge appears.

Naturalness state

Among the social behaviour types the disturbance tolerant species (47%) and the generalist (29%) species dominate because of the half natural human activity (Fig. 4) which did not introduce many new species. Therefore ruderal species do not play an important
