  1. Provide or retain set-aside areas in farmland

    A randomised and replicated site comparison in the winters of 1992-1993 and 1993-1994 on 40 farmland sites in Devon and East Anglia, UK (Buckingham et al. 1999) found that only one taxonomic group (finches, sparrows and buntings, seven species) showed a significant preference for set-aside habitats in both years, preferentially using sown set-aside less than one year old. Conversely, thrushes (four species) and hedge-dwelling species (European robin Erithacus rubecula, wren Troglodytes troglodytes and dunnock Prunella modularis) avoided regenerating set-aside less than one year old in Devon. At a species level, a preference for set-aside was seen in both winters by one species in Devon (cirl buntings Emberiza cirlus selecting sown set-aside more than one year-old) and two species (plus one introduced species not considered here) in East Anglia (grey partridge preferred older sown set-aside and yellowhammer Emberiza citrinella selected one year-old sown cover). A further 13 species in both East Anglia and Devon preferentially selected a set-aside habitat in one winter. Blackbirds Turdus merula and five other species avoided some set-aside in at least one year in Devon; no native species did so in East Anglia. The same 40 plots (50-100 ha) were surveyed each winter, although the amount of set-aside they contained varied due to rotation schemes.
