  1. Provide or retain set-aside areas in farmland

    A replicated, randomized site comparison study of 27 arable fields on a farm in southern Finland over one year (Kinnunen and Tiainen 1999) found that the abundance of ground beetles (Carabidae) was significantly higher in set-aside than crop fields.  Set-aside contained 1,442 beetles/site compared to 334-524/site in crop fields.  Of 21 species compared in set-aside and cereal fields, two were significantly more abundant in set-aside (Trechus secalis, Dyschirius globosus) and two in cereal (Asaphidion pallipes, Bembidion quadrimaculatum). The ground beetle community differed between set-aside and crop fields.  Autumn breeding species dominated set-aside (70% in June), whereas spring breeders tended to use crops tilled in spring (56-80%). Twenty-seven of 150 fields were randomly selected.  Six were permanent set-aside, sown with perennial grass and left for 5-10 years. The others were barley, oats, sugar beet, oilseed rape and potato. Beetles were sampled using 20 pitfall traps (7 cm diameter) at each site.  These were emptied every two weeks for 10 consecutive weeks from June-August 1995.
