III. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS 



A. THREATS TO CURRENTLY KNOWN POPULATIONS: 



1. GRAZING: Young rosettes of species in the genus 

 Cirsium are palatable to grazers, but adult 

 flowering plants are often not preferred. Due to 

 unpalatability, many introduced species of Cirsium 

 are increasers with heavy grazing, but the effect 

 on this native species is not known.
