SUMMARY While QMS had significant positive relationships with species rich ness in both EPs and PWs, these relationships were stronger in the PWs. In addition, QMS was more important to species richness within PWs than EPs. The only environmental variable that was a significant predictor of species richness in both EPs and PWs was pH (Table 2).

Discussion: Richness relationships between EPs and PWs. PWs had higher mean plant species richness than EPs. This result was likely due to the smaller size of the EPs. Alternatively, their more ex-
