Snowmobiling is allowed \nin designated routes and trails and the establishment of the routes require a \nspecific permit. However, snowmobiles are heavy, so the snow compacts under \nthe sled causing the snow cover to thin and the sled can damage vegetation that \nwould otherwise have been sheltered under the snow. Additionally, \nsnowmobiling on peatland ecosystems can change in the structure and function \nof the peatland. This can be observed, among other things, as a decrease in the \naerated strata, the sinking of the pine mire tussocks and damage to the dwarf \nshrub vegetation. The aim of this research was to investigate what kind of effects \nsnowmobiling has on peatland vegetation, how snowmobiling affects the \nnumber of species of peatland plants and the species composition of the plant \ncommunity and has the compaction of the now any impact on the number of \nspecies in peatlands. The research was executed as a two-phase field test. It was \nconducted in five peatlands located in Central Finland or in its immediate \nvicinity. The measurements in the first phase were made in winter and the snow \ndepth, density and the width of the trail were measured in every peatland. On \nthe peatlands three lines were made perpendicular to the trail, from which the \nsnow measurements were made in three different measurement spots. In the \nsecond phase, in summer, the vegetation was analyzed in the same spots where \nwinter measurements had been conducted. Plant species, their number and \nabundance ratios were measured and compared later to the undisturbed control \nareas. The data was processed by Excel and statistical tests were run by SPSS \nsoftware program. As a result, it was found out, snowmobiling reduces the \ncoverage of Carex-vegetation in tall sedge fens, whereas the dwarf shrub cover \nreduces in the dwarf shrub pine bogs. Also, the depth of the snow had an impact \nto the amount of the species and the species composition changed. There were \nsome references of negative impact to peatland vegetation that was caused by \nsnow compaction. In every peatland the snowmobile trail was visible to the bare \neye and the vegetation under it was either damaged or even dead, though there \nwas not so much statistical evidence to prove the differences between the \nvegetation coverage. On the trail, there were also completely open moss-free \nspots, that weren\u2019t present in the control area. In conclusion, it can be stated that \nsnowmobiling has negative effects on peatland vegetation in the disturbed area.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2023-12-15T09:39:43Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2023-12-15T09:39:43Z (GMT).
