Figure 2: Relationship between crop yield and abundance of insectivourous birds across treatments; O – open access and B – Birds excluded. Shaded areas represent ±1 SE. Predicted lines plotted from the model in Table 2A: change in yield with abundance is not significant, but differences according to treatment are
