Environmental Data: Soil respiration - exclosure experiment

Soil respiration Switzerland

ID: Fence number Year :Year of sampling mean.CO2: soil respiration measured with PP-systems SRC-1 soil respriation chamber attached to a EGM-4 infrared gas analyser; units CO2 g m-2 h-1 Grassland: Grasslands where fences were errected. Note that on large grasslands (STAB, GRIM, MING) 2 pairs of fences were errected (2 in short, 2 in tall-grass vegetation), on small grasslands (DADA, MARG, BOTS) only one pair of fences was errected (1 short-grass; one-tallgrass vegetation) Fence: Fence number; un-even numbers on short-grass vegetation (1,3,5,7,9,11,13,15,17), even numbers on tall-grass vegetation (2,4,6,8,10,12,14,16,18) Vegetation: 1 = shortgrass vegetation, 2 = tall-grass vegetation (9 replicate fences on each vegetation type) Treatment : 1 = all herbivores grazing, 2 = large ungulates (red deer, chamois) excluded
