Plant grass buffer strips/margins around arable or pasture fields
A replicated, controlled trial in North Yorkshire, UK (Shore et al. 2005) found more bank voles Clethrionomys glareolus and common shrews Sorex araneus on sown grass field margins in autumn than on control cropped margins, but no such differences in spring. There were 13-14 and 26-38 bank voles/autumn trapping period on 3 m and 6 m margins respectively, compared to 0-1 voles on control margins. There were 14-15 and 10-13 common shrews/autumn trapping period on 3 m and 6 m margins respectively, compared to 1-4 common shrews on control margins. Wood mice Apodemus sylvaticus were found in similar numbers on all margin types in autumn and spring (0-29 mice/trapping period). Four 3 m-wide and four 6 m-wide field margins were established in autumn 1997 and sown with a mix of grasses on one arable farm. Small mammals were trapped in spring (April-May) and autumn (September-October) 1999 and 2000 on sown field margins and four conventional cropped field edges (controls). On four separate nights in each trapping period, twenty Longworth traps were set 10 m apart on each margin, 10 along the edge furthest from the crop, and 10 placed 2 m into the crop. This study was carried out at the same experimental site as Telfer et al. 2000, Carvell et al. 2004.
