Vegetation % cover, cover classes, and locations for all mire-wide plots in Stordalen Mire, northern Sweden, sampled in July 2015. Class = the 5-category classification of Malmer et al., 2005. Cover type = the 3-category classification of Bäckstrand et al., 2008. Each of the 75 plots had 64 subplots that were each quantified for % cover, such that the total plot-level %cover=Sum(species)/64. Sum(SUM) is total of all other Sum() columns. Sum(0) and Sum(0 2) are data compilation checks. FUNDING: National Aeronautics and Space Administration, Interdisciplinary Science program: From Archaea to the Atmosphere (award # NNX17AK10G).
