Creek road (Beaverhead National Forest road #83). Drive 

 approximately 0.25 miles, then turn east on a small dirt 

 road that parallels the Big Hole River. Walk or drive ca . 

 2.0 miles east on this road. Site is north of the road on 

 the west side of a small draw as marked in Figure 1, p. 3. 

 Pins were driven into the ground at the four corners of the 

 covered exclosure, and the outside corners of the adjacent 

 control plot.

METHODS 



The two study sites were established on 11 June 1991. At 

 each site, four metal stakes were driven in at the corners of the 

 exclosure (approximately 6 ft x 6 ft) . A long tape measure and 

 several yard sticks were used to divide each plot into four 

 subplots as illustrated below.

Within each subplot, the number of rosettes, and the number 

 of flowering and fruiting plants were tallied. In addition, the 

 percent cover of the dominant associated plants, and in one case, 

 rocks, was also recorded. These same methods were used to obtain 

 data from control plots. 



RESULTS AND DISCUSSION 



A summary of the 1991 population data and percent cover of 

 vegetation and rock from the Quartz Hill and Thompson's Corner 

 plots are presented in Tables 1 & 2, p. 4 and 5, respectively. 

 The Quartz Hill Gulch site had a higher density of A. fecunda 

 plants and lower total vegetation cover than the sample plot at 

 Thompson's Corner as reflected by the exclosure and control 

 totals for each site. The lower density of A. fecunda plants at 

 Thompson's Corner is likely due to site characteristics (i.e. the 

 cover of rock was quite high) rather than other factors.
