Tourbières d'Aapa

Mire complexes in southern, middle and northern boreal zones characterised by minerotrophic fen vegetation in the central parts of the complexes. Hydro-topographical mire-units are: mixed mires, string-fens, flark-fens, unraised Sphagum fuscum-bogs, unpatterned topogenous or soligenous lawn-, carpet or mud-bottom fens. Poor Sphagum fens are the most common vegetation types whilst brown moss fens can be common in some regions. In prealpine areas in Sweden and in hill regions of Kainuu and Kuusamo in eastern Finland, sloping fens (>5 grades) are typical variants of aapa mires. They occur rarely also in the Suomenselkä water divide region in western Finland as well in Lapland. In the mire margins, pine mires and spruce swamps and mires on thin peat of different types dominate. In some limited areas with calcareous bedrock rich fens dominate in the complexes.
