  1. Plant grass buffer strips/margins around arable or pasture fields

    A replicated, controlled study in 2006 in central Oxfordshire, UK (Merckx et al. 2009b) found no difference in moth (Lepidoptera) abundance or diversity between 6 m (agri-environment scheme option) and about 1 m (standard option) wide field margins in four lowland farmland areas. In each area, one farm with standard margins and one with 6 m-wide margins were sampled. Three Heath pattern actinic light traps (6 W) were set up on each farm ?100 m apart and >50 m from hedgerow intersections. Traps were placed on 2 m2 white cotton sheets 1 m from hedgerows bordering fields with no banks or ditches. All farms were sampled once during each of 11 discrete fortnightly periods from mid-May to mid-October 2006. Sampling was carried out from dusk till dawn during nights with suitable weather conditions. At dawn, all individuals were identified to species, species-pair or genus, marked with a unique number and released where caught.
