EXECUTIVE SUMMARY 



Ouercus macrocarpa (bur oak) , a sensitive plant species on the 

 draft Bureau of Land Management sensitive plant list for Montana, 

 was systematically surveyed in the Powder River Resource Area of 

 the Miles City District. Scattered BLM tracts in the Alzada 

 area south of Thompson Creek were screened. Four of the BLM 

 tracts in the area contain Ouercus macrocarpa . together making up 

 ca. 1% of the local oak stand. The stand was mapped as extending 

 over 10 miles in length, as a series of groves with major 

 discontinuities. Conservation status information for Ouercus 

 macrocarpa was compiled in the course of the study and the BLM 

 tracts evaluated relative to conservation concerns and needs.
