Observed species composition in first growing season (2013)

Presence/absence information of plant species in 675 0.1x0.1-m squares belonging to 27 permanent plots of 0.5x0.5 m, sampled in the first growing season (2013). Each permanent plot contained 25 squares (5 rows and 5 columns), which were numbered from left to right, beginning in the first row of the permanent plot. The first column (‘square.id’) is a running number containing the square ID. The second column (‘plot.id’) gives the ID of the plot, linking the table to the other tables. The third column (‘square.no’) gives the number of the square in the respective permanent plot. All other columns contain presence/absence information of the plant species. 1, species present; 0, species absent.
