This paper presents the edge effect of a very low-volume road on the belt of roadside vegetation in the "Puszcza Notecka", Poland - one of the largest compact forest complexes in Europe. The observations were carried out in the vicinity of pine stands in the fresh coniferous forest and fresh mixed coniferous forest sites. Twelve rectangular experimental sites 30 and 50 meters wide at a distance of 0 to 10 meters from the edge surfaces were established. 75 species characteristic for the 13 phytosociological classes and 20 species associated devoided of the diagnostic value were recognized in the roadside area. Native species dominated, where the most numerous species belonged to meadow communities (Molinio-Arrhenatheretea) and ruderal (Artemisietea vulgaris). Despite the significant participation of synanthropic plants, there was no invasion of alien species. ...
