Table 1 Single best generalised linear mixed models for (a) dung density, (b) sward height, (c) plant species richness and (d) rare plant species richness. S.E. standard error.

From: Agri-environment schemes are associated with greater terrestrial invertebrate abundance and richness in upland grasslands
