Searches were conducted on foot in both known and potential habitats of target species, including 

 particularly large, intact, and/or well-developed habitat settings. Special attention was paid to unusual 

 habitats occurring in wetland and rock outcrop settings. Efforts were made to visit all large sectors of 

 the study areas during effective times of the field season. 



Field information was compiled on the Plant Species of Special Concern Survey Form, and the 

 populations mapped onto U.S. Geological Survey topographic maps (7.5'). Data collected included 

 detailed information on vegetation, slope/aspect, soil, population size, species biology, and management 

 considerations. Photographs were taken of target species and their habitats (35 mm slides). These have 

 been printed to accompany this report and also conveyed as slide duplicates. Lists of vascular plant 

 species other than those of special concern were not maintained for the scattered areas making up this 

 study. 



Voucher specimens of the target species were collected if they provided new distribution or phenological 

 stage information and when adequate material was available in keeping with the Montana Native Plant 

 Society's collecting guidelines (^4NPS 1993). Specimens will be deposited at the University of 

 Montana Herbarium (MONTU) and at the Montana State University Herbarium (MONT). Some 

 collections were made of other species if field identification proved difficult or when their presence in 

 the study area represented a major extension of the known range. Following the field season, unresolved 

 taxonomic questions were researched in both of the above herbaria, and determinations or verifications 

 were made in consultation with taxonomists. Such was the case for the genus Hordeum (John H. 

 Rumely, Montana State University) and the genus Erigeron (Sarah Gage, University of Washington). 



Technical references most commonly used to key plants were Dom (1984) and Hitchcock and Cronquist 

 (1973). Nomenclature used in this report generally follows these references.
