Managing reindeer lichen during forest regeneration procedures: Linking Sami herders' knowledge and forestry
In northern Sweden, conventional forest regeneration procedures applied in modern commercial forestry can disturb terricolous lichen (Cladina spp.) pastures. This has become a source of conflicts with Sámi reindeer herders. The overall aim of this thesis was to investigate forest regeneration strate...

In northern Sweden, conventional forest regeneration procedures applied in modern commercial forestry can disturb terricolous lichen (Cladina spp.) pastures. This has become a source of conflicts with Sámi reindeer herders. The overall aim of this thesis was to investigate forest regeneration strategies that may minimise the disturbance to, and promote the regeneration of, reindeer lichen pastures. The Sámi herders' practices and knowledge related to the lichen resources were also analysed. Effects of gentle soil preparation methods on the re-establishment of lichen cover, reindeer grazing and establishment of Pinus sylvestris planted seedlings were studied in a field experiment.
