variety of habitats in North America ranging from low 

 elevation meadows, riverbanks, sand dunes and woods to 

 high elevation alpine meadows (Cody and Britton 1989, 

 Lellinger 1985) . 



In Montana, Botrvchium minqanense occurs in lov/ 

 elevation, moist forests as well as alpine areas with 

 an elevational range of 945-2035 m (3100-6680'). 

 Detailed habitat information is available only for the 

 sites in Ninemile Creek valley (006 and 007) . In these 

 locations, Botrychium minqanense occurs in deeply- 

 shaded creek bottoms in moist to wet Thuja plicata / 

 Oplopanax horridum and Thuja plicata /CI intonia unif lora 

 habitat types. This is similar to the habitat described 

 for some of the Idaho occurrences (Lorain 1990) 

 although other occurrences there are in habitats such 

 as a disturbed Pinus contorta/Vaccinium qlobulare 

 forest and a regenerating forest of small Pseudotsuga 

 menziesii and Abies lasiocarpa with a dense, shrubby 

 understory that had been logged and burned 30 years 

 previously. 



1. ASSOCIATED VEGETATION: Botrychium minqanense

 Thuja plicata - Tsuqa heterophylla forests. Other 

 associated plant species include: 



Abies qrandis (grand fir) 

 Picea enqelmannii (Engelmann spruce) 

 Oplopanax horridum (devil's club)
