Distribution of vegetation on mesic forest sites in relation to some characteristics of the tree stand and soil fertility.

Vegetation data collected from a random sample of mature forest stands representing mesic upland forest sites in Southern Finland were analysed and classified using two-way indicator species analysis (TWINSPAN). The variation of some characteristics of the tree stand and soil fertility between the produced vegetation units were analysed statistically. Both the species list and the sample list arranged by TWINSPAN reflects the overall site fertility considerably well. The results are in agreement with the main division of mesic forest sites in the Finnish forest site type classification: vegetation units which can be assigned to the site type are clearly separated from the remaining units, and the overall site fertility indicates a statistically significant difference. The within-type variation in the vegetation composition in the site type reflects the variation in site fertility, whereas the within-type variation in the site type is mainly caused by the tree stand factor.Oxalis-MyrtillusOxalis-MyrtillusMyrtillus
