Synopsis 



Vegetation structure appears to 

 have changed little since 1927 

 other than some decline in the 

 density of Opuntia polycantha. 

 In contrast to the 1959 descrip- 

 tion, Agropyron smithii is now 

 the overwhelmingly dominant 

 grass species. We also suspect, 

 based on the 1959 photo as 

 opposed to the written descrip- 

 tion, that it was quite abundant 

 then as well.
