This area was resurveyed for A. brevistyla by 

 Wayne Phillips (Lewis & Clark National 

 Forest) during the summer of 1991. Where the 

 fire burned away the duff layer, A. 

 brevistyla plants did not survive. However, 

 if the duff layer was still intact, the root 

 crown was apparently protected, and basal 

 leaves appeared in 1991. Plants in very 

 lightly burned areas not only survived, but 

 many flowered in 1991 (Phillips 1991) . 

 Although precautions were made, a salvage 

 timber sale may eliminate portions of what is 

 left of the surviving plants. It is also not 

 known how the loss of shade will affect the 

 population. Several stakes were set in 1991 

 by Lewis & Clark National Forest personnel. 

 These marked the location of groups of 

 suspected vegetative A. brevistyla plants. 

 These stake areas should be resurveyed in 

 1992, and the entire area reviewed for 

 several years to make general observations on 

 this species response to fire. 



G. POPULATION ECOLOGY 



1. BIOLOGICAL INTERACTIONS 



a. COMPETITION: Aguilegia brevistyla plants 

 were observed to occur where total understory 

 vegetation cover may reach 90 percent; they 

 appear to compete very well. Partial 

 overstory shade was common, and only a few 

 plants were observed in more open locations 

 at the edges of meadows. Often these more 

 open sites would receive shade from the 

 adjacent forest and steep ridges. 



b. HERBIVORY: None observed.
