Reduce tillage
A replicated, controlled study in the winters of 2000-2003 in 63 experimental and 58 control winter wheat and barley fields in Oxfordshire, Leicestershire and Shropshire, UK (Cunningham et al. 2005), found that Eurasian skylarks Alauda arvensis, seed-eating songbirds and gamebirds occupied a significantly higher proportion of fields managed through non-inversion tillage than conventionally ploughed fields in late winter (January-March). Species richness of seed-eating songbirds was also higher on non-inversion tillage fields (five species vs. one on conservation tillage fields). No birds showed any preference for field type in early winter (October to December), and crows, pigeons and insect-eaters showed no preference across the study period. Field size ranged from 1.6 to 22.3 ha, with similar numbers of non-inversion tillage and conventionally ploughed farms censused each year.

No birds showed any preference for field type in early winter (October to December), and crows (Corvidae), pigeons (Columbidae) and insect-eating birds showed no preference across the study period. Field size ranged from 1.6 to 22.3 ha, with similar numbers of non-inversion tillage and conventionally-ploughed farms censused each year. This study was part of the same experimental set-up as (Cunningham et al. 2002, Cunningham 2004) and is also described in an additional publication (Cunningham et al. 2003).
