Sphagnum annual growth and primary production measurements (Mukhrino field station, West Siberia) (2018-2024)

Measurements of annual growth of Sphagnum spp. were started in Mukhrino field station (West Siberia) in 2018 as part of the complex program on carbon dynamics in raised bog ecosystems. The main goal of this project is to estimate general characteristics of growth/primary production of different species of Sphagnum in Mukhrino bog. Totally 57 plots were located along the wooden boardwalks of the field research polygon. Measurements were carried out using modified crancked wire approach (brush-wire) (S. fuscum, S.magellanicum, S.angustifolium, S.papillosum, S.capillifolium) or individual wire ringlets (S. majus, S.jensenii, S.balticum). Part of the plots were under warming experiment conditions (Open Top Chambers). Totally 3226 measurements were made during 2018-2024 growth seasons, including: 1) growth increment of sphagnum shoots, 2) number of capitulas per dm^2, 3) weight of 3cm length shoots per dm^2, and 4) weight of capitulas per dm^2. The project is launched in collaboration with the Institute of Soil Science and Agrochemistry, Novosibirsk.
