Abundance of vascular plants measured using point intercept frequency.

The datasets contains point frequency data (which can be converted to biomass estimates) of the following functional groups and species:

  • Betula nana
  • Broad leaved grasses
  • Calamagrostis phragmitoides
  • Deciduous dwarf shrubs
  • Deciduous vascular cryptogams
  • Deschampsia cespitosa
  • Empetrum nigrum
  • Equisetum sp
  • Evergreen dwarf shrubs
  • Evergreen non woody
  • Green willows
  • Grey willows
  • Hemiparasites
  • Nardus stricta
  • Narrow leaved grasses
  • Prostrate willows
  • Rumex acetosa
  • Salix herbacea
  • Sedges and rushes
  • Small forbs
  • Tall forbs
  • Vaccinium myrtillus

The dataset includes three different types of files and all files (except the readme) are saved as ;-separated txt-files:

  • One data file per year (_YEAR.txt)
  • One coordinate file with coordinates of all sites included in the dataset (_coordinates.txt)
  • One auxiliary file with information about which sites are included in the dataset and when (_aux.txt)
  • One readme file with additional information about the variables included in the study design (_readme.pdf)

The dataset has a two-year embargo, older versions of the dataset are publicly available for download.
