The biodiversity metrics assessed featured high within-group variation from the treatment means (Fig. 2-5). This is a indication that local environmental conditions and legacy effects of initial plant communities prior to setting up exclosures strongly influence plant communities, which was also reflected in the high proportion of deviance explained by location and block in GLMs. The deviance is especially high for the forb to graminoid ratio, which is in accordance with field observations, where some quadrats featured an almost complete dominance of either forbs or graminoids.
