Undersow spring cereals, with clover for example Farmland Conservation

A controlled study in May to September 2000 in the sub-urban area of Vienna, Austria (Kromp et al. 2004) found no difference in the number of ground beetle (Carabidae) species between one rye field undersown with a wildflower mix (approximately 20 species) and four conventional fields without wildflowers (approximately 12-26 spp.). The number of ground beetle species in the undersown rye field was lower than on two types of set-aside land (unsown or sown with a wildflower mix). No statistical analyses were presented in this paper. Typical crops for the region were sown on five arable fields. One of the fields was under conservation contract growing a wildflower seed mix undersown with rye. Ground beetles were sampled using four pitfall traps 10 m apart in each habitat and site. There were five sampling periods each year, each lasting two to three days (2001) or seven days (2000).

Provide or retain set-aside areas in farmland Farmland Conservation

A replicated, controlled study in May to September 2000-2001 on six farmland sites near Vienna, Austria (Kromp et al., 2004) found a higher number of ground beetle (Carabidae) species in set-aside areas than in arable fields. Sowing wildflower seed mixtures on set-aside land further increased the number of ground beetle species. The community composition of ground beetles differed between the three types of habitat. No statistical analyses were presented. Two unsown set-aside fields were >50 and six years old and cut regularly. Wildflower strips (four sites) were sown on set-aside land with the Voitsauer seed mix containing 25 species of herbs and weeds between 1998 and 2000. Typical crops for the region were sown on five arable fields. One of the arable fields was under conservation contract growing a wildflower seed mix undersown in rye. Ground beetles were sampled using four pitfall traps 10 m apart in each habitat and site. There were five sampling periods each year, each lasting two to three days (2001) or seven days (2000).

Plant nectar flower mixture/wildflower strips Farmland Conservation

A replicated, controlled study in May to September 2000 and 2001 in the suburban area of Vienna, Austria (Kromp et al. 2004) found more ground beetle (Carabidae) species in sown wildflower strips on set-aside land than in arable fields and on unsown set-asides. Ground beetle community composition differed between the three habitat types. No statistical analyses were presented in this paper. There were six farmland sites. Wildflower strips (four sites) were sown on set-aside land with the “Voitsauer” seed mix containing 25 species of wildflowers and weeds between 1998 and 2000. The two unsown set-asides aged six and >50-years-old were cut regularly. Typical crops for the region were sown on five arable fields. One of the arable fields was under conservation contract, growing a wildflower seed mix undersown in rye. Ground beetles were sampled using four pitfall traps 10 m apart in each habitat and site. There were five sampling periods each year, each lasting two to three days (2001) or seven days (2000).
