The data presented here was collected during the 1994, 1996, 1998, 2000, 2002, 2007 and 2008 summer field seasons using a fixed, 75 cm square point frame, with 100 measurements spaced 7 cm apart. At each of 100 points per plot, the following information was recorded in a spatially explicit format: species hit, condition and woodiness. More information on methods can be found in Walker (1996).
