About one-third of plot situ- 

 ated under a Zizyphus 

 bush, where the vegetation 

 is much more abundant 

 than in the remainder of 

 the area, but it represents 

 an average for this kind of 

 situation. 



Gently sloping open foothills. 

 Eachsi-Iioltzia mexicana very 

 abundant a short distance 

 away, but comparatively 

 few plants within 20 rods 

 of the plot. Besides the 



■ jilants li.sted there are 31 

 seedlings of Gxrtneria tenu- 

 ifolia and 10 bunches of 

 perennial grasses. 



On a sandy, gravelly wash 

 which has not been dis- 

 turbed for about two years. 

 The plants in .situations 

 like this habitually grow 

 much larger than in other 

 places. They are, however, 

 much fewer in number. 



Typical representation of the 

 uneroded lands just above 

 the washes and below the 

 rockv bluffs on either side. 



■ It is'between areas of this 

 nature and the sandy wash- 

 es that trees and shrubs 

 grow in this part of the iu- 

 closure. 



Typicjil development in the 

 "protection of bushes. 



96S Uneroded. In other respects 

 not different from Plot A. 



Surface soil partially re- 

 ■ moved by erosion. 



Surface soil largely removed 

 by flood waters.
