Figure 1.
The number (±s.e.) of rare and common (a) plant and (b) bumble-bee species, and (c) Hedge's d (±95% CIs) comparing bird species number, recorded on general and evidence-based habitats with a cereal crop control. Species richness of common and rare plants was highest on evidence-based habitats and similar between general and control habitats (common, F2,76 = 112.39, p < 0.001; rare, F2,76 = 17.16, p < 0.001). The same pattern was seen for species richness of common and rare bumble-bees, except that common bees were also more diverse on general than control habitats (common: F2,73 = 75.38, p < 0.001; rare: F2,73 = 6.70, p < 0.01). Common and rare bird numbers were higher (signified by d > 0) in the evidence-based habitat compared with both the general habitat and the control, and the latter two treatments had similar numbers (d was not significantly different to 0). White bars represents common species, grey bars represents rare species.
