a Groupings of species correspond to cluster membership. 



Results of cluster analyses suggest that cluster membership for 

 tree data provide better indicators of hydrologic zones than saplings or 

 vines. Shrubs and herbaceous species would be the least useful of all 

 strata types. 



Discriminant Function Analysis 



Discriminant function analysis (DFA) is used to determine func- 

 tions which allow one to classify an individual into one of the
