The work in the Bridger and Crazy Mountains was broader 

 in scope, but included similar efforts to relocate historical 

 occurrences of target species. The two historical species of 

 concern in the Bridgers were Artemisia norvegica var. 

 saxatilis , represented by a 1958 collection from Fairy Creek, 

 and Potentilla diversifolia var. multisecta , also known from 

 the Crazies, based on collections taken around the turn of the 

 century. Searches were conducted in the Crazy Mountains for 

 Salix cascadensis , known by a 1945 collection from near 

 Granite Lake, and for two target species known from more 

 recent collections, Erigeron flabellif alius (from 2 locations: 

 above Sunlight Lake and above Trespass Creek) and Juncus 

 covillei (from Big Timber Canyon) . No attempt was made to 

 relocate populations of Agoseris lackschewitzii , which was 

 recently surveyed in the Crazies. No other target species are 

 known to occur on the Gallatin National Forest in these two 

 ranges. 



I searched for these species at their known locations as 

 well as in suitable habitat elsewhere in the ranges. Searches 

 were made on foot usually on day hikes, but a three-day 

 backpack trip was taken in the Crazy Mountains. Maps showing 

 survey routes are included as Appendix A in this report. 



When populations of target species were found, they were 

 surveyed and sensitive plant survey forms were filled out. 

 Population numbers were estimated and their precise location 

 and boundaries were mapped. Data gathered on habitat included 

 dominant and associated vegetation and edaphic attributes of 

 the site. Specimens of the plants were collected, and often, 

 photographs of the site and close-ups of the plants were 

 taken. 



In conjunction with the species specific searches, 

 general floristic inventories were conducted. A broad range 

 of habitats were surveyed on the way to and from the 

 historical target species sites. In some areas of exceptional 

 habitat, preliminary surveys were conducted in the absence of 

 known element occurrences. In all areas visited, daily 

 species lists were made, including all vascular plant taxa 

 which were recognized or could be keyed out. These lists were 

 necessarily incomplete, because locations were generally 

 visited only once during the season. From these daily lists a 

 master list of species identified on the GNF was constructed 

 (Appendix B) . The field guides used most often to key out 

 plants were Dorn (1984) and Hitchcock and Cronquist (1973). 



Collections were made of all target species and of many 

 other taxa, especially those which were difficult to identify 

 in the field or which seemed to be outside their known range. 

 Specimens were pressed and dried in the usual manner, and 

 identified in the herbarium in the fall. Determinations of
