Relationship between live bitou bush cover (%) and site species richness and cover/abundance of (a,d) plants, (b,e) birds, and (c,f) small mammals. Predicted values from the top-ranked GLMM and 95% confidence intervals, as well as raw values (closed circles) are shown. Predictions were made by holding other variables included in the top-ranked model at its mean value (see Table 2). Species richness for each assemblage was calculated as the number of species detected per survey effort for each survey period at each site. Plant cover was calculated as the average percent cover of native species from four 1 × 1 m2 quadrats for each survey period for each site. Abundance of fauna was calculated as the number of individuals detected per survey effort for each survey period at each site (see Methods for details).
