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.

The interest in peatland forestry in Quebec is increasing as the peatlands of the St-Lawrence valley are considered to have a good drainage response capacity A relatively important forest drainage project is being carried out on a practical scale. However, the lack of a practically oriented peatland classification system is an important drawback. This paper is an attempt to produce a preliminary classification system intended for practical peatland forestry. Keywords: Quebec, forest drainage, site type classification.
