Trampling is recognised as a cause of disturbance in grassland and heathland vegetation along two public nature trails in Sølendet nature reserve in central Norway. The effects of trampling by visitors and of controlled trampling were monitored over a period of 5–7 years in permanent plots. A retrogressive development was recorded as vegetation cover and height were reduced and a substantial loss of species richness and biomass took place. Some species, mainly graminoids such as Agrostis capillaris and Carex vaginata , initially appeared to be more tolerant, but were eventually reduced as well. Low, geophytic and prostrate habits of growth and hardy leaf tissues seemed to be beneficial for tolerance to trampling. Moist grassland and lichen‐dominated heathland were more vulnerable to trampling than dry grassland. Even though 350–1500 visitors walked through the permanent plots along the trails each summer, effects on the soil surface remained moderate and only a minor furrow was visible on the ground.
