The area of Koilliskaira, situated in the eastern part of Finnish Lapland, is a popular venue for hikers. The present work examines the change of vegetation around 35 refuge huts in the area. The indigenous vegetation was found to conform to the various heath forest types common to forests in Lapland and continental subalpine mountain birch forest types, principally dry or fairly dry heath forest.
According to the study, the change in vegetation showed a clear positive correlation with the number of summer visitors. The dwarf shrubs and lichens were the most susceptible to trampling, and the grasses the least so. Both resilient and susceptible species were to be found among the mosses. The incoming hemerophilous flora was seen to consist principally of species known to accompany Lappish settlement in the area, and only occasional cases of alien species were noted.

The study deals with the trampling tolerance of forest vegetation in a Myrtillus type closed forest of Norway spruce (Picea abies (L.) H. Karst.), based on the effects of simulated trampling on the coverage and biomass on the field and between layers of the vegetation. The reliability of the results from the simulated trampling was tested by comparing them with those obtained from real trampling.
According to the results, the trampling tolerance of the bottom layers is greater than that of the field layer. The trampling tolerance of different species varies, so that grasses and dwarf shrubs have a higher tolerance capacity than herbs. Even light trampling of short duration caused noticeable changes in the coverage and biomass of the ground vegetation. Despite certain deficiencies, the simulated trampling gave parallel results of those obtained for real trampling.
