Abstract:A list of plant species encountered during the ITEX flux survey, with their corrresponding 6 letter codes and functional groups. Research sites were located in the Toolik Lake LTER fertilization experiment in Alaska; at Imnavait Creek, Alaska; at Paddus, Latnjajaure and the Stepps site near Abisko in northern Sweden; at various sites in Adventdalen, Svalbard; in the Zackenberg valley, Northeast Greenland; at BEO near Barrow, Alaska and at the Anaktuvuk River Burn in Alaska. Data was collected during the growing seasons 2003 to 2006.

TAXONOMIC COVERAGE:
Organisms studied
 
Methods:METHODS:
This is the main species list describing plant species encountered during the ITEX survey. Plots were established for measuring flux data and for harvesting biomass for analysis. All species found in flux and/or harvest plots are summarized in this table.

If a species was found in a particular location, it is checked under the appropriate column (Abisko, AR Burn, Barrow, Svalbard, Toolik, or Zackenberg).

Species codes are made from the first 3 letters of genus and species names. If only the genus is known, the genus code is followed by SPP.

COMMENTS: Note that this list is not comprehensive, species present in very low abundance were not identified. Many species, particularly graminoids, were identified only to genus.
