Additions to the Vascular Flora of the Pasvik Strict Nature Reserve, Murmansk Region

Abstract

Information about 24 vascular plant species found for the first time in the Pasvik strict nature reserve in 2008–2014 is reported. Seventeen of the species: Woodsia glabella , Botrychium multifidum , Equisetum × litorale , Equisetum × trachyodon , Arctagrostis latifolia , Poa lapponica , Carex lapponica , Carex serotina , Eriophorum latifolium , Eriophorum gracile, Dactylorhiza incarnata , Nuphar lutea , Salix reticulata , Saxifraga cespitosa , Ribes nigrum , Ribes spicatum and Alchemilla kolaensis are native; three species: Anthoxanthum odoratum , Alchemilla propinqua and Trifolium hybridum are adventitious; four species: Juncus minutulus , Coccyganthe flos-cuculi , Myosotis nemorosa and Lactuca sibirica are presumably adventitious. Five of these species are rare and listed in the Red Data Book of the Murmansk Region (2014). The patterns of distribution of each species in the Murmansk Region and the area adjacent to the nature reserve, as well as the reasons for classifying some species native in the region as adventitious in the nature reserve are discussed. For many of both native and adventitious species the newly detected habitats are the northernmost in the Murmansk Region.
