English title: The nature of two sloping mires in the Riisitunturi national park, northern Finland

Tiivistelmä

The vegetation (mapped with the point method), mire profiles and peat depth are very shortly described (Fig. 2 and 3, tables in the text). Typical of the sloping mires above 300 m a.s.l. are Sphagnum fuscum and Carex globularis spruce-pine mires along the marginal parts of the mire complexes. The middle parts of the mires are often dominated by oligo- and mesotrophic flark fens and Molinia caerulea – Scripus cespitosus – Spagnum compactum - Ptilidium ciliare vegetation; the last mentioned is very similar to the northern boreal short-sedge fen vegetation at the west coast of Northern Norway. Mesotrophic springs and springy patches or stripes are common. All this reflects poor bedrock and hygrid oceanic climate (the temperature climate is continental). This has caused a heavy paludification of the heath (forest) vegetation. Carex-Sphagnum and Sphagnum peats with wood remains dominate usually. Overgrown places can be traced occasionally in the top parts of the mires.
