however, these were counted as R, 

 individuals in the data analysis. 

 At each of the three study sites, 25 

 fruits were collected from randomly 

 selected individuals outside the 

 transects. The fruits were dissected, 

 and the number of viable-appearing seeds 

 in each was recorded. 



C. RESULTS AND DISCUSSION: A summary of 

 the population density and fecundity 

 data collected in 1989 is presented in 

 Table 2. In the three transects, a 

 total of 240 plants were mapped and 

 scored. The French Creek-Park Mine site 

 had the highest recorded density, and 

 the individuals at this site also had 

 the highest percentage of fruiting 

 plants. The lowest density, and the 

 lowest average numbers of fruits per 

 plant and per inflorescence, were 

 recorded at the French Creek-Discovery 

 Mine site. This site also had the 

 highest percentage of browsed stems; it 

 appeared that this browsing was by 

 native species (probably deer) . Very 

 few seedlings were observed in general, 

 and none were found in the French Creek- 

 Discovery Mine transect. Those observed 

 (4 at French Creek-Park Mine, 13 at 

 Badger Pass North) were very small, and 

 it is possible that others within the 

 transects were missed during the 

 studies. Also, numerous seedlings may 

 perish or become dormant earlier in the 

 growing season, as the habitats become 

 drier. Seedlings of Silene spaldingii , 

 a rare perennial plant species occurring 

 in northwestern Montana, become dormant 

 during the summer months under 

 greenhouse conditions (Lesica 1988) . 



4. AREAS SURVEYED BUT SPECIES NOT LOCATED: The 



following areas were surveyed for Penstemon 

 lemhiensis in 1989, but the species was not 

 located within them. The actual areas surveyed 

 are smaller than the portions of the sections 

 indicated.
