Plant grass buffer strips/margins around arable or pasture fields
A replicated, paired, site comparison study in 2009 in a mixed farming region in Brittany, France (Delattre et al 2013) found that grass field margins were used by meadow brown Maniola jurtina butterflies in a similar way to meadows. Meadow brown flight patterns in grass field margins were similar to those in meadows (data presented as model results). In addition, meadow browns were more likely to fly along grass margins than across them. Meadow brown behaviour was studied in three pairs of grass field margins (5–20 m wide, 20–340 m long) and small meadows (0.05–5 ha), at sites 4–8.5 km apart. Grass field margins were mostly sown with a standard set of clover Trifolium spp. and grasses (Poacea). From June–August 2009, a total of 289 butterflies using field margins and 270 butterflies using meadows were followed individually from 15 m away, and the length and direction of their movements was recorded.
