1. BIOLOGICAL INTERACTIONS 



a. COMPETITION: This small annual may be a poor 

 competitor. See the discussion under soil 

 relationships, p. 16.

H. LAND OWNERSHIP 



1. U.S. Forest Service, Kaniksu National Forest, 

 managed by Kootenai National Forest. 



Bull River Cliffs (005) 

 Dry Bench (006) 

 Goat Rocks (007) 



II. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS 



A. THREATS TO CURRENTLY KNOWN POPULATIONS: There are 

 currently no apparent threats to populations of Madia 

 minima in the Bull River valley on Kootenai National 

 Forest lands. f 



B. MANAGEMENT PRACTICES AND RESPONSE: Madia minima and M. 

 exiqua were often found in association; however, in 

 low-lying areas where timber harvesting had occurred 

 only Madia qlomerata was observed. It is not known why 

 M. minima was not present in such areas. 



C. RECOMMENDATIONS FOR MAINTAINING VIABLE POPULATIONS: 



The locations of the known populations on the Kootenai 

 National Forest are in areas that are unlikely to be 

 affected by most management practices, and the 

 populations are probably self-maintaining. 



D. RECOMMENDATIONS FOR FURTHER ASSESSMENT: There is 

 additional habitat along the Bull River drainage that
