We completely
surveyed both sites in two consecutive inventories: the first inventory was
conducted in 2010 and the second in 2015. On both sites, each of all
free-standing woody stems with a diameter at breast height (dbh) greater than 1
cm was georeferenced and tagged, and the species and dbh were measured on site.
A total of 46,458 trees were tallied in 2010, and 44,564 trees were tallied in
2015.
