Along alkaline roads, fast and profound shifts in physical–chemical soil properties (pH increased from 3.9 up to 7.6, base saturation from 9–30% up to 100%) were recorded. The roadside vegetation (meso- to nitrophilous species and species preferring man-made habitats) doubled in area. The intensity of changes depended significantly on the type of road material and the position relative to the road. To prevent the further damage we recommended replacement of alkaline gravel by granite. The reconstruction of trails has already started.
