A final model was generated to examine the effectiveness of using 

 the average site FTI numbers of all observed tree species at a site for 

 each of the 55 sites. This model correctly classified 45 of 55 sites for 

 an overall misclassif ication rate of 18.2 percent (Table 12). All 

 misclassif ications were in an adjacent zone. Zones 2, 3, and 5 were mis- 

 classified twice; Zone 4 was misclassif ied 3 times; and Zone 6 was mis- 

 classified only once. Using FTI numbers for all observed tree species 

 improved the results obtained in the first DFA using the importance values 

 of only the commonly occurring species. 



In examining the data (Table 13) , it appears that three of the mis- 

 classifications occur at site 10 (Pearl River, observations 27 to 30). 

 The hydrology at this site was obtained from two gauges, and it is
