English title: Relation of peat nutrients to ground vegetation communities on sedge pine fens

Tiivistelmä

Vegetation and peat nutrient data from 167 sample plots representing microsites on sedge pine fens are related. The plant data was analysed by two numerical multivariate methods: DECOR AN A-ordination and TWINSPAN-classification. The connection between the results of the numerical analyses and the surface peat nutrient contents is discussed. Phosphorus, calcium and magnesium showed the closest relationship to those plant sociological variations that were interpreted as trophy-dependent. The variation in soil data within classes could not be diminished by using numerical classification methods instead of the Cajanderian peatland site type. Keywords: peatland classification, peat nutrient contents, multivariate analysis.

Avainsanat
