Some theories and experimental studies suggest that areas of low plant species richness may be invaded more easily than areas of high plant species richness. We gathered nested-scale vegetation data on plant species richness, foliar cover, and frequency from 200 1-[m.sup.2] subplots (20 1000-[m.sup.2] modified-Whittaker plots) in the Colorado Rockies (USA), and 160 1-[m.sup.2] subplots (16 1000-m: plots) in the Central Grasslands in Colorado, Wyoming, South Dakota, and Minnesota (USA) to te...
