Figure 3. --Plot scores (•) for DCA ordinations. The first axis 

 is the horizontal axis and the second or third axis is the 

 vertical axis. Numbers in diagrams indicate the number of 

 multiple plots at that ordination position. X, Y, and Z 

 denote situations with more than 9 plots at that ordination 

 position. 



3a - First and second axes; all 125 plots. X, Y, and Z 

 represent 12, 54, and 14 plots at the respective 

 ordination position. 



3b - First and third axes; all 125 plots. X, Y, and Z 

 represent 20, 27, and 21 plots at the respective 

 ordination position. 



3c - First and second axes; all 16 forest plots. 



3d - First and second axes; all 53 shrubland plots. X 

 represents 33 plots at that ordination position. 



3e - First and third axes; all 53 shrubland plots. X, Y, 



and Z represent 20, 10, and 16 plots at the respective 

 ordination position. 



3f - First and second axes; 34 shrubland plots v/ith ARTLON/ 

 ORYHYM, ARTTRI/FESCAl'l, SARVER/ATRGAR, SARVER/PASSMI , 

 ATRCON-ARTTRI , and JUNHOR/SCHSCO plots removed. 



3g - First and second axes; all 56 grassland plots. X 

 represents 10 plots at that ordination position.
