English title: The rich fens of the Lapland triangle region

Tiivistelmä

The Lapland triangle region, located between the lower courses of the rivers Tornion-joki and Kemijoki in NW-Finland covers an area of 3500 km2. The region is renowed for its concentration of rich fen mire site types, including Campylium stellatum — Limprichtia intermedia — rich fens, eutrophic flark fens, eutrophic birch fens, eutrophic pine mires and eutrophic spruce mires. Peatlands cover about 60 % of the total land area of the region. By the end of the 1970's some 90 % of the area of rich fens had been drained and utilized for cultivation and forestry purposes and several plant species had become endangered. Although some 20 sites have been listed for conservation, enforcement so far has been very limited. Keywords: fens, peatland drainage, endangered species, conservation.
