The trampling tolerance of ground vegetation of different types of forest stands has been examined in this study in the light of short-term trampling. The trampling treatment was simulated by a mechanical tamp. The relation between deterioration of the ground vegetation and the amount of the trampling was presumed to follow a curvilinear pattern when the material was being analysed. In order to quantify this relationship, a mathematical equation was developed for every plant community and their members of which the trampling tolerance was analysed. The trampling tolerance was compared using a parameter of the developed equations. Vegetation growing on sites of the Myrtillus, Vaccinium and Calluna types was included in the study.
The study showed a clear difference in the trampling tolerance between the ground vegetation of sites differing in their fertility. The ground vegetation typical of the Calluna type was found to have a lower trampling tolerance than the vegetation of the most fertile sites which were studied. It can be concluded that the relationship between the site fertility and the trampling tolerance of the ground vegetation is a curvilinear one such that the trampling tolerance of the vegetation on the poorest and the richest sites is lower than that of the vegetation growing on sites of medium fertility. However, it does appear that the most fertile sites have a higher trampling tolerance than the poorest sites. In addition, information about the trampling tolerance of a number of commonly occurring forest plants is also presented.
