Synopsis 



Grass density has increased 

 significantly since 1916. A few 

 plants of Populus deltoides have 

 become apparent in a drainage 

 near the center between 1959 

 and 1998. Conifer species, 

 predominantly Pinus ponderosa, 

 have increased on the moun- 

 tain. Two species, Agropyron 

 intermedium and Agropyron 

 cristatum, which were seeded 

 along the edge of a golf course 

 near this site, are now invading 

 the site.
