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... -
Passerine bird
The avifauna is monitored with special emphasis on passerine birds representing the highest trophic level. Weekly counts of birds are carried out at 13 census points during the... -
Arthropod
Arthropods are sampled by means of yellow pitfall traps. Window traps are used for flying insects. The traps are emptied weekly throughout the snow free season. For further...
