The tolerance of disturbance of the ground and field layer vegetation in a moderately fertile Norway spruce (Picea abies (L.) H. Karst.) on Oxalis-Myrtillus type forest in Southern Finland was studied. One of the sites, a summer cottage yard had been raked regularly during the last 25 years. The structure of the vegetation was quite different compared to the other sample site situated in a virgin forest. The phytomass and percentual coverage of the vegetation was remarkable lower in the raked habitat. Tall mosses, Pleuroxium schreberi and Hylocomnium splendens had especially disappeared. Most grass shrubs had also deteriorated. Only Deschampsia flexuosa was quite tolerant to raking. The phytomass of the dwarf shrubs was lower in the raked area but their relative production was higher. Three different kinds strategies of species were described: species of virgin shaded forest, species of meadow-like forest floor and species which tolerate or benefit from disturbance. The raked habitat had a higher species diversity than the virgin area. Nitrogen and carbon contents were lower in the soil of the raked area.

English title: Factors affecting deterioration of urban forests.

The objective of the study was to investigate the factors affecting the deterioration of urban forests based on literature. Regression analysis is applied to the material obtained from unpublished material of the latter author. The size of forest stand, and its fertility proved to exercise the greater effect on the deterioration of urban forests. A model based on these factors has been developed and its area of applying is discussed.

Seppo Kellomäki. (1978). Recreational potential of a forest stand. Silva Fennica vol. 12 no. 3 article id 5001. https://doi.org/10.14214/sf.a14855

The aim of the paper was to investigate the recreational potential of successional stand based on the suitability of the stands for different recreational activities and the trampling tolerance of ground cover. The relationship between selected recreational activities and the volume of the stands under study has been determined. These functions have been utilized in determining the potential of the successional stand for different recreational activities. Combining this information with trampling tolerance gave criteria for determining the recreational potential of a stand. The results emphasize the importance of varying the distribution of development stages in a recreational area and in its management.

English title: Ground cover response to trampling in a spruce stand of Myrtillus type.

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.

Seppo Kellomäki, Varpu-Leena Saastamoinen. (1975). Trampling tolerance of forest vegetation. Acta Forestalia Fennica no. 147 article id 7581. https://doi.org/10.14214/aff.7581

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.
