Abstract [en]

Ski slope construction is one of the major anthropogenic factors responsible for ecosystem degradation in mountain areas in Finnish Lapland. Mt. Yllas has been used as a downhill skiing slope for about 30 years. Until 1992, the ski slopes were kept in their natural condition: There was no removal of vegetation and soil above the tree line. After 1992, Mt. Yllas went through an extensive construction, the ski slopes were machine-graded and machine-levelled, which caused damage to both vegetation and soil. The aim of the study presented here was to examine nutrient status of various soils on the machine-graded and machine-levelled ski slopes in relation to their potential use as a substrate for revegetation practices. Soil organic matter and nutrient status were analysed in three sites on the slopes of Mt. Yllas in the tree line zone (transit zone between wooded vegetation and treeless alpine vegetation): (1) reference site on the undisturbed area between the ski-runs (Control); (2) disturbed site on the ski-run area (DSP - 'DiSturbed Podzol', - DSL 'DiSturbed Leptosol' and DSB - 'DiSturbed Bare soil'); and (3) Revegetation study Plots established on the ski-runs (RP). The analysis of element concentrations and their relative proportions allow us to conclude that only DSP and DSL can be considered as potentially appropriate for unassisted ecosystem recovery on the ski-runs. Presence of native plant species on these patches supports our conclusion. As a recommendation for revegetation of ski-runs, we propose implementation of substrate composed of upper layer of initial soil. Such substrate can be collected during the construction work on ski slopes or on building sites in the area with similar soils. Uncomposted substrate or at least short period of composting is preferable.
