  • Salix phenology in carbondioxide flux plots

    The reproductive phenology of Salix glauca is followed in all plots. The total number of catkins in each carbon flux plot is counted on a weekly basis diveded into the number of...
  • Salix phenology

    For Salix glauca four observation plots were established in order to cover the ecological amplitude of the species with respect to duration of snow cover, difference in soil...
  • Plot NDVI (discontinued)

    The progression in the vegetation greenness (Normalized Difference Vegetation Index; NDVI) is followed in the plant phenology plots on a weekly basis. NDVI is measured by a Crop...
  • Plot NDVI

    The progression in the vegetation greenness (Normalized Difference Vegetation Index; NDVI) is followed in the plant phenology plots on a weekly basis. NDVI is measured by a...
  • Pinpoint analyses in carbondioxide flux plots

    Pinpoint analyses data are done every 5 years in the carbon flux measurement plots. First time in 2017. For further details, please refer to the newest BioBasis manual available...
  • NERO line Raunkiaer

    The NERO line is a permanent vegetation transect crossing all the dominating vegetation types found in the study area. For information on Raunkiaer Circle data, please refer to...
  • NERO line NDVI (discontinued)

    The NERO line is a permanent vegetation transect crossing all the dominating vegetation types found in the study area. The progression in the vegetation greenness (Normalized...
  • NDVI in carbondioxide flux plots

    The progression in the vegetation greenness (Normalized Difference Vegetation Index; NDVI) is followed weekly. NDVI is measured with a handheld SpectroSense 2+ system. For...

  • Loiseleuria phenology

    For Loiseleuria procumbens four observation plots were established in order to cover the ecological amplitude of the species with respect to duration of snow cover, difference...
  • Leaf fluorescence (discontinued)

    The effect of increased UV-B radiation on plant stress is monitored indirectly by measuring chlorophyll fluorescence in three series of plots: Controls, plots with a filter...
  • Carbondioxide flux

    Carbon fluxes are measured weekly. The vegetation in the CO2 flux plots is dominated by Empetrum nigrum heath with Salix glauca as subdominant species. Soil moisture is measured...
  • Microarthropod

    Soil samples are collected with a soil corer from which the organisms are extracted in a heat extractor by gradually heating up. Samples are taken from permanent plots 3 times...
