Production of eight species of Sphagnum at Suurisuo mire, southern Finland

The thickness increment, production of dry matter and volumetric density of Sphagnum carpets were measured during three years using the so-called net method. The Sphagnum species studied were S. magellanicum, S. papillosum, S. majus, S. angustifolium, S.flexuosum, S. riparium, S. warnstorfii and S....

Description
Summary:The thickness increment, production of dry matter and volumetric density of Sphagnum carpets were measured during three years using the so-called net method. The Sphagnum species studied were S. magellanicum, S. papillosum, S. majus, S. angustifolium, S.flexuosum, S. riparium, S. warnstorfii and S. fuscum. The greatest thickness increments were recorded for S. angustifolium and S. riparium. The most productive species were S. fuscum, S. majus and S. riparium. The highest volumetric densities were measured in the S. fuscum and S. majus carpets; in the former this was due to its great shoot number and in the latter to its dense floating carpet. Carpet thickness was a poor predictor of dry matter production, as the growth patterns and site conditions varied greatly between species. The importance of the three variables studied is discussed with reference to the habitats and autecology of the Sphagnum species.
