Synopsis 



Since the 1959 photo, the bot- 

 tomland has been cultivated and 

 planted to Medicago sativa 

 (alfalfa) and Hordeum vulgare 

 (barley). The density and cover of 

 Pinus ponderosa on Judith 

 Mountains in the background 

 has continued to increase over 

 time. Similarly, the density and 

 size of streambank shrubs have 

 continued to increase, although 

 species diversity has remained 

 relatively stable.
