Kosonen R. Isovarpuisen rämeen kasvibiomassa ja tuotos.

Tiivistelmä

An example of this very common pine bog site type was analyzed in Vilppula, Central Finland in the zone of eccentric bogs in 1973 and 1974. The mean above-ground biomass and net-production of different layers and plant species was determined (Table 1 and Fig 1). The total above-ground biomass on this sample plot of IR pine bog was 1872 g/m2 and the total production 234 g/m2. The biomass was dominated by tree stand (80,5 %), but in the production the lower layers were better represented (field layer 38,5 % and ground layer 14 %). The distribution of biomass and production was rather similar to that of different ombrotrofic bog types studied (see Vasander 1981 c). The most prominent distinguishing feature was the smallnes of moss biomass and production in the IR site type.
