Vegetation 1. Estimation of cover/abundance follows the method of Braun-Blanquet (Kent & Coker 1992). 2. Scale for estimate: r = 1-3 individuals; + = <1% few individuals; 1 = 1-5% / many individuals; 2 = 6-25% / large number of individuals; 3 = 26-50%; 4 = 51-75%. Data were transformed into mean values of classes. 3. Plot size: 0.8 m2 4. Approx subsite area: c. 20 m x 15 m = 300 m2 5. Missing taxa and year: No acro- and pleurocarpous bryophytes (XXXacrocarpousmoss, XXXpleurocarpousmoss) and lichen CETISL in 1994 and 1996. [At the moment, data does not contain 2009 bryophyte data] 6. Description of warming treatment if applicable: hexagonal OTCs during 1994-1996 and 2009-2010. No OTCs 1997-2008.
