RESULTS 



SUMMARY 



New information was obtained on nine target species from 

 fieldwork and herbarium work, providing a basis for re- 

 examining their current status (Table 2) . A historical 

 occurrence of 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 

 Erigeron flabellif alius and Mimulus suksdorfii but are not 

 recommended for sensitive status. A new population of 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, including Artemisia norvegica , Juncus 

 covillei , Potentilla diversifolia var. multisecta , and Salix 

 cascadensis , are probably based on misidentif ications or 

 taxonomic discrepancies. 



A total of 368 taxa of vascular plants were identified on 

 the Gallatin National Forest (Appendix B) . Results from each 

 of the four areas and from the Gallatin National Forest 

 Herbarium search are summarized first, followed by species 

 specific synopses. 



1. Bridger Mountains 



Despite intensive searches, the historically reported 

 population of Artemisia norvegica was not relocated. Plants 

 closely resembling the historical collections of Potentilla 

 diversifolia var. multisecta were found to be common along the 

 crest of the range, however these plants are probably all P. 

 diversifolia var. perdissecta. No other target species were 

 found in the Bridger Range and no others are reported. A 

 total of 219 vascular plant taxa were identified. 



2. Crazy Mountains 



The population of Erigeron flabellif olius known from 

 Sunlight Lake in the Crazy Mountains was relocated and another 

 population was discovered on "Glacier Pass." Populations of 

 Juncus covillei and Salix cascadensis could not be relocated 

 despite searches at their named localities. A total of 214 

 plant taxa were identified. 



3. Hyalite Canyon 



Two subpopulations of Sidalcea oregana were located above 

 Hyalite Reservoir; these are probably from the same sites as 

 the historical collections at MONT. A total of 121 plant taxa 

 were identified in the canyon.
