Table 2 Top five lowland models predicting Cirsium vulgare presence, ranked by AIC_c. Also included are the number of parameters included in the model, the change in AIC_c, model weights, residual deviance, residual degrees of freedom, and percent variance explained. Model parameter abbreviations are as follows: burn severity (BSlevel; +1 = high, 0 = moderate, −1 = low), elevation (elev), transformed aspect (Taspect; −1 = north, +1 = south), species richness (SR), post burn basal area (post). Elevation, species richness, and post burn basal area are all standardized around the mean.
