Extended Data Table 3 Agri-environment schemes and linear features: nectar productivity and provision in England in 2007

From: Historical nectar assessment reveals the fall and rise of floral resources in Britain

  1. a, Mean nectar productivity values of agri-environment schemes were estimated from our nectar productivity database combined with flower counts in these options. Areas of options providing floral resources in the English agri-environment scheme ‘Environmental Stewardship’ were extracted for 2007 from data supplied by Natural England38,39. b, Mean nectar productivity values of linear features correspond to back-transformed (10x – 1) estimates of the linear mixed model fitted on log10 (x + 1) nectar productivity of all Countryside Survey linear plots surveyed in England in 2007. National areas of hedgerows were estimated from the length given in Countryside Survey 2007 for England35 and assuming a 1 m width.
