Alpine plants

Central parts of Fillefjell are situated about 1000 m above sea level with surrounding peaks reaching 1812 m (Sulefjellet). The altitudinal gradient can be seen from subalpine to low-alpine, mid-alpine and high-alpine zones. The sub-alpine zone is dominated by mountain birch forest, partly penetrated by sub-alpine mires. In the low-alpine zone willows are abundant, with Salix lapponum (lappvier) as a dominating species. The mid-alpine is dominated by alpine heaths, with species such as Betula nana (dvergbjørk), Phyllodoce caeruleum (blålyng), Empetrum hermaphroditum (fjellkrekling), Vaccinium myrtillus (blåbær) and others. Extensive snowbeds (snøleier), alpine ridges (rabber), alpine meadows (alpine enger), and screes (rasmarker) are also found in the mid-alpine zone. Frost is prominent in the high-alpine zone and this is a major reason for the lack of a complete vegetation cover. Sparse vegetation and clusters of individual plants are typical for this region. Vascular species found on the highest peaks include Ranunculus glacialis (issoleie), Diphasiastrum alpinum (fjelljamne), Luzula arcuata (bogefrytle), Poa flexuosa (mjukrapp), Carex bigelowii (stivstarr), Cardamine bellidiflora (høgfjellskarse) and others.
