Methods

Vegetation 1. Braun-Blanquet scale. 2. Cover % (cover class midpoints) 3. Plot size: (50 x 50 cm = 0.25 m2) 4. Approx subsite area (30 m x 50 cm = 15 m2) 5. Cryptogams were not identifiied in the study, only total Moss and lichen cover. 6. Control (no warming treatment) Climate: 1. Standard equipment and methodology from the Icelandic Met Office, data is from their long term stations. For the Dalsmynni station we provide data for the period 1997-2005, ATM, ATMX, AT and Precip. 2: 3: Start of growing season was not determined. 4: Precip data missing from Nov. 2003. 5. LAT, LONG and ELEV for climate station if different from subsite location, using same format as below LAT = 65.658 LONG = -20,2925 ELEV = 8 m a.s.l. Permanent plots for long-temer monitoring of vegetation were set up in pastures in the lowlands and highlands of Iceland in 1997-1998. The plots were resampled in 2005. Analysis of the data showed that a considerable improvement in pasture condition had in general occurred. Grazing pressure had declined, sward height increased, extent of bare ground declined, cover of vascular plants increased and cover of crytogams declined. Overall vegetation change was from a heathland towards a grassland. The vegetation change was related to declining livestock numbers and grazing pressure, but not the less to a warming climatic trend during the period.
