  1. Provide or retain set-aside areas in farmland

    A small site comparison study in Belgium (Desender & Bosmans 1998) found 53 species of ground beetle (Carabidae) during one year of sampling in three set-aside fields, including eleven species in the Red Data Book for Flanders. The most notable species were Amara tricuspidata and Harpalus froelichi. Thirty-five of the species were considered to be breeding within the fields. The set-aside fields contained more ground beetle species than were found in previous years on cultivated arable fields (numbers not given). Two of the fields were set-aside in 1994, sown with grasses and annually mown once. These were managed without fertilizers or pesticides for two years before becoming set-aside. The other field had been left to naturally regenerate since 1992, and was partly grazed by sheep. Beetles were sampled between May 1994 and April 1995 in three pitfall traps per site, emptied fortnightly or monthly throughout the year.
