Table 4. Fecundity (fruits/plant) for Arabis fecunda at Birch 

 Creek (1987-90) and Charley's Gulch (1987-89) and the effect of 

 Centaurea maculosa removal (treatment) , site, year and their 

 interactions on Arabis fecunda fecundity during the first two 

 years of the experiment by ANOVA. Fecundity was log-transformed 

 before analysis. Sample sizes for individual sites and years can 

 be found in the "Fruiting plants" rows in Table 3.
