Synopsis 



Bottomland is Warm Spring 

 Creek. Rather dramatic increase 

 in abundance of Salix spp. has 

 occurred since 1917, whereas 

 abundance of Populus spp. has 

 declined. Abundance of Pinus 

 ponderosa on mountains and 

 buttes has also increased tre- 

 mendously since 1917, as that 

 of Shepherdia argentea (origi- 

 nally reported as S. canadensis) 

 on hillsides and bottomland. 

 Creek has changed courses 

 several times; note its direction 

 is different in each photo. The 

 1959 photo shows a wide and 

 somewhat less meandering 

 stream compared with the 

 earlier and later photos.
