  1. Plant new hedges

    A replicated study in 1998 and 1999 in mid-Wales (Hayes et al. 2001) found that seven species planted in two hedgerows in semi-upland farmland supported significantly different numbers of arthropods: common gorse Ulex europaeus (1007 arthropods), sessile oak Quercus petraea (436), blackthorn Prunus spinosa (381), hawthorn Crataegus monogyna (258), silver birch Betula pendula (180), rowan Sorbus aucuparia (110) and ling heather Calluna vulgaris (53). Sessile oak was the most diverse in terms of arthropod orders, with 13 out of 15 orders recorded, two of which were not found on any other host. Hawthorn and common gorse were the next most diverse, each with one unique arthropod order. Common gorse, sessile oak, blackthorn and rowan between them had representatives of all 27 families of beetles (Coleoptera), true bugs (Hemiptera) and moths and butterflies (Lepidoptera) recorded in the study. All planted species had a similar or better growth rate than the commonly planted hawthorn, apart from sessile oak and ling heather. Planting was undertaken in 1996 within the fenced (2 m-wide) margins of two fields. Margins were divided into eight 6 m plots, which were planted with a double row of 30-40 plants of each species, replicated across three blocks. Invertebrates were sampled by tree beating at five points/plot in June, August and September (1998-1999).
