We studied the biomass production of moss species typical of pine-dominated drained peatland forests to evaluate their potential role in the carbon cycle of such sites. The study was carried out at two sites in Lakkasuo, central Finland. Prior to drainage, the sites had been mesotrophic and ombrotrophic. Shoots of Pleurozium schreberi, Sphagnum angustifolium, S. fuscum, S. magellanicum and S. russowii were marked in the autumn of 2004 and 2005, incorporated back in the original patches, recovered one year later, and measured for height growth, biomass, and biomass production. Biomass production varied from 16 to 388 g dry mass m–2 yr–1. Both height growth and biomass production were higher at the mesotrophic site, while biomass estimates did not show distinct difference between sites. Variation in production within each dominant species was considerable. A simulation with our production values and published estimates of decomposition rates showed that these species have the potential to contribute significantly to soil carbon storage in drained peatlands.
