English title: Vascular plant species in planned mire conservation areas in southern and central Finland

Tiivistelmä

The occurrence of the threatened and endangered vascular mire plant species was inventoried in the mire conservation areas in Finland. The survey was based on 246 sample plots (0.5 km × 0.5 km) randomly chosen in the Finnish mire conservation areas planned in 1981 in southern and central Finland. In the inventory, 243 vascular plant species and 2 hybrids were found in bog mires and 249 species and 10 hybrids were found in the southern aapa mires. The majority of the found mire plant species commonly occur on mires in Finland. In this survey, out of 18 threatened primary mire vascular plant species occurring in Finland, only three species (Carex heleonastes L. f., Dactylorhiza incarnata ssp. cruenta (O. F. Mull.) P. D. Sell, D. cruenta (O. F. Mull.) Verm, Orchis cruenta (O. F. Mull.) and Dactylorhiza traunsteineri) (Saut. ex Rchb.) Soo´, Orchis traunsteineri Saut. ex Rchb., Dactylorchis traunsteineri (Saut. ex Rchb.) Verm.; incl. Dactylorhiza curvifolia (F. Nyl.) Czerep.; incl. D russowii (Klinge) Holub and only one so called secondary mire plant species (Carex paniculata L.) were found in the sample plots. The found species occurred only on six mire conservation areas. Compared to the size of the material, the percentage of findings of threatened vascular plant species was remarkably low. It can be concluded that the complementary programs of the mire conservation in Finland have been important to protect the threatened vascular mire plants.
