This file contains plant community composition data from plots within each of 29 restored prairie sites in Southwestern Michigan. Each site contains 10 1x1m vegetation sampling plots spaced evenly along a 45m transect, at the approximate site center. Values denote percent cover of each plant species found in each of the 1x1m plots. Sampling occurred from August 13th to the 21st in 2013. Cover in each plot can sum to greater than 1 if individuals were overlapping. Cover does not need to sum to 1 due to the presence of bare ground (not included in this dataset).
