 by hikers is a threat to all three 

 populations but is greatest on St. Mary Peak 

 where a formal trail exists. 



3. Potential threats: Continued recreational 

 use could further threaten the populations. 



B. Overutilization for commercial, sporting, 

 scientific, or educational purposes: No threats 

 known.
