A list containing a phylogeny for XX species of Oldfield forbs, as well as a presence / absence dataset for their occurrence across several locations in Southern Ontario see Dinnage (2009) for details. Sites each had two plots which experienced a different treatment each; either they has been disturbed (ploughed 1 or 2 years previously), or they were a control plot (undisturbed in recent records).
