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

    A replicated, controlled study in 1997-2000 in Essex, UK (Field & Mason 2005) found that numbers of the gatekeeper butterfly Pyronia tithonus increased in sown grass margins one year after establishment and were significantly higher in 2000 than in 1997. Although more gatekeepers were recorded in grass margins than in control sites (without margins) during most visits (except for one farm in 1998), abundance was significantly higher at only one farm. More gatekeepers were observed on grass margins with adjacent hedgerows and on control sites with hedgerows than on the grass margins without hedgerows. Grass margins (2 m wide, 141-762 m long) were established in October 1996-2000 by sowing three different grass seed mixtures (eight margins: 4-5 species, mainly Dactylis glomerata; one margin: 6 spp., mainly Festuca rubra). Three field edges without margins (one on each of three farms, 133-343 m long, 100-300 m hedgerow) were used as controls. Gatekeeper abundance was monitored weekly along transects in July and August. This study is part of the same experimental set-up as Field et al. 2005, Field et al. 2006, Field et al. 2007a, Field et al. 2007b.
