  1. Pay farmers to cover the cost of conservation measures (as in agri-environment schemes)

    A replicated site comparison study over 20 years in the UK (Brereton et al. 2008) found that chalkhill blue butterflies Polyommatus coridon increased more on sites with agri-environment scheme agreements than sites without. Chalkhill blue numbers increased on average 3.16%/year at 66 sites with Countryside Stewardship Scheme or Environmentally Sensitive Area agreements, compared to no significant trend at non-scheme sites. Chalkhill blues were counted annually from 1981 to 2000, at 161 sites across its entire UK range. This was part of the UK Butterfly Monitoring Scheme, which takes weekly transect counts along a set route at each site and follows standardized weather conditions.
