Tiivistelmä

Some preliminary results of a technique used to compare primary production and peat accumulation data mainly from published sources and the results of a peat accumulation simulation model are presented. Emphasis is on differences among micro-sites (hummock, lawn, hollow and pool) and among various Sphagnum species (S.fuscum, S. magellanicum, S. cuspidatum and S. balticum) associated with raised bogs. The primary production of lawns and pools were significantly greater than those of hummocks and hollows. Sphagnum balticum had the highest primary production (mean = 339 g m-2 a-1). Over 90% of the primary production of Sphagnum fuscum is accumulated while for the other Sphagnum species, the value is <50%. The data are used in a simulation model to show the influence on primary production of a doubling of rainfall over a 50-year period. Keywords: Meta-analysis, peatland, primary production, Sphagnum
