Restoration of a disturbed area in an alpine environment : Evaluation of the revegetation projects of the area around the abandoned underground mine in Stekenjokk (English)
The aim of this study was to evaluate restoration methods used in a revegetation project for the heavily disturbed area around the abandoned underground mine Stekenjokk, located in an alpine area in Västerbotten County, Sweden. The studies were initiated in 2013 by Enetjärn Natur AB on behalf of Boliden Mineral AB and several methods were adopted in the purpose of investigating the feasibility of different restoration methods. Seeding, plantation of adult plants and transplantation of vegetation turfs were performed in combination with addition of organic matter. In addition, ‘safe sites’ were created either by addition of cobbles to the surface, creation of holes in the ground or by putting out coconut mats. All plant material, e.g. seeds, plantation of adult plants and transplantation of vegetation turfs, resulted in new establishment of plants in the area. Spontaneous establishment of plants was also observed in several of the examined plots. Several of the methods used are probably suitable for restoration of the old industrial area in Stekenjokk. However, the success varied among different methods and there was a tendency for higher survival of plants in experimental plots to which soil had been added. A combination of addition of plant material (seeds or adult plants), addition of organic matter and creation of ‘safe sites’ seemed most effective in accelerating revegetation in the heavily degraded area in Stekenjokk. However, sample sizes were small and more studies should be conducted to confirm the generality of this conclusion.
