Synopsis 



An abundance of Melilotus 

 officinalis is evident in the 

 1998 photo but not in earlier 

 photos. However, only very 

 small seedlings were present 

 during the 1999 site visit. This 

 reduction was attributed to 

 mechanical or herbicide treat- 

 ment or both. The amount of 

 Pinus ponderosa on Black 

 Butte has increased consider- 

 ably over time. Although the 

 presence of Opuntia spp. is 

 noted in 1959, it was not 

 present in 1998 or 1999.
