EXECUTIVE SUMMARY 



Four areas of the Gallatin National Forest, including 

 the Bridger and Crazy Mountains, Hyalite Canyon, and the upper 

 Gallatin Valley, were surveyed for sensitive species 

 recognized by Region 1 of the U.S. Forest Service, and for 

 prospective sensitive species currently tracked as Montana 

 plant species of special concern. A historical occurrence of 

 Oregon checker-mallow (Sidalcea oregana) was relocated in 

 Hyalite Canyon, and is recommended for addition to the U.S. 

 Forest Service sensitive species list. New populations were 

 found of fan-leaved daisy {Erigeron flabellifolius) and 

 Suksdorf monkeyf lower (Mimulus suksdorfii) but are not 

 recommended for sensitive status. A new population of Wolf's 

 willow {Salix wolfii var. wolfii) was also found; it is 

 currently recognized as sensitive on the U.S. Forest Service 

 sensitive species list, but this status may warrant re- 

 examination pending annotation of all Salix wolfii specimens 

 in Montana to variety. 



Herbarium work revealed that historical reports of four other 

 species on the Gallatin National Forest are probably based on 

 misidentif ications or taxonomic discrepancies. They include: 



boreal wormwood Artemisia norvegica 



Coville's rush Juncus covillei 



diverse-leaved cinquefoil Potentilla diversifolia var. 



multisecta 

 Cascade willow Salix cascadensis 



In addition, Gallatin National Forest Herbarium specimens were 

 organized and reviewed for sensitive species collections. Two 

 records were found, one for Wind River draba {Draba ventosa) 

 and another for Wolf's willow (Salix wolfii var. wolfii). The 

 site of the Wolf's willow was relocated in the course of this 

 survey project. The site of the Wind River draba was not 

 known until further literature search revealed that it was 

 apparently collected from what is now within Beaverhead 

 National Forest rather than Gallatin National Forest.
