Aspect: 180 degrees 



Instructions: Read transect west to east. 



METHODS 



On June 15 (Lime Gulch) and 16 (Canyon Creek) , we 

 established two permanent belt transects of 12 adjacent m^ plots 

 at each site, following the methods outlined in Lesica (1987). 

 The start and end points of each transect were marked by a 

 section of reinforcing bar driven into the ground and painted 

 orange. Individual A. fecunda plants were mapped and recorded 

 using the following system: 



S - Seedling (rosette less than 15 mm diameter) 



R - indicates the number of rosettes (> 15 mm diameter) per 



plant 

 I - indicates the total number of inflorescences (stems) 



per plant 

 F - indicates the total number of fruits produced by the 



plant 



Thus, a plant with two rosettes, three stems and a total of nine 

 fruits would be recorded as R1-I3-F9. In cases where plants had 

 not finished blooming, two flowers or flower buds were recorded 

 as one fruit. Since a first year plant can bloom and set fruit 

 (Lesica and Shelly, personal observation) , the above system 

 describes size rather than age classes. 



At each site, we located 25 randomly-chosen plants outside 

 of the transects, and picked one fruit from each. We dissected 

 each fruit, and recorded the number of viable-appearing seeds in 

 each. 



Many of the plants at Canyon Creek were still flov/ering when 

 we read the transects; thus we recommend that this transect be 

 read in late June or early July. 



RESULTS AND DISCUSSION 



A summary of the data collected in 1989 is presented in 

 Table 1. All plants were mapped and scored to size class within 

 each of the four transects. Fecundity was much greater in the 

 Canyon Creek population than the Lime Gulch population. Also, 

 the Canyon Creek population had a higher percentage of plants 

 with more than one rosette. The Lime Gulch population is ca. 

 1,000 ft lower in elevation and in the rain shadow of the Pioneer 

 Mountains. The differences in fecundity could be an artifact of
