Figure 2.

Percentage cover of (a) native and (b) non‐native plant communities on five different soil treatments. Soil treatments were created in a common‐garden experiment by growing target plant species for 4 years then removing vegetation. Native and non‐native communities were then grown for 3 years prior to measurement. Mean cover ± 1 SE shown. Bars with different lower case letters different at the α = .05 level. Numbers above bars indicate sample size. PSSP, Pseudoroegneria spicata; BRTE, Bromus tectorum; CEDI, Centaurea diffusa; Mixed, a naturally recruiting mix of species; SILO, Sissymbrium loeselii
