Methods

BioTIME managers note: for v2, only control plots were retained. Vegetation 1. Vegetation was analysed by using a 30 X 60 cm frame divided into 18 10 X 10 cm subplots. Species abundances were recorded in each subplot. Each species were given a value between 0 and 3, where 0 = absent, 1 = rare, 2 = frequent, 3 = dominant. Litter, bare soil, and total vegetation cover was measured as % cover per sub-plot and averaged per pl 2. The Abundance units were calculated by using presence/absence values in subplots (sub-plot frequencies). 3. Plot size: 0.18 m2 4. Approx subsite area ca 800 m2 5. Missing taxa and year missing: no cryptogams sampled in 2004 6. Warming treatment: hexagonal OTCs
