pressure. Since this species occurs most often in barren soil, it may 

 resptjnd ptwitively to moderate leN-els of disturbance. 



C. RECOMMENDATIONS FOR MAINTAINING VIABLE POPULATIONS: 



Eriotft)num la gopus is common and widespread at the north end of the 

 Bighorn Basin in Carbtm County (and probably Bighorn County). Montana 

 and Bighorn and Sheridan counties, Wyoming. It is unhkely that any 

 reasonable management or recreational activities could threaten the 

 persistence of this species in southern Carbon County.
