Allow natural regeneration of ground cover beneath perennial crops
A replicated, randomised and controlled study in an apple Malus domestica orchard in Asturies, Spain in 2000 (Minarro & Dapena 2003) found that ground beetle (Carabidae) abundance was similar in plots with naturally regenerated ground cover (33 captures/trap) and rotovated control plots (48 captures). The second most common ground beetle species, Pseudophonus rufipes, was significantly less numerous in the vegetated plots (0.13 captures/trap) than in the control (28 captures). Treatment blocks (comprising a row of 11 trees) were replicated four times in the 5 ha orchard. The regenerated ground cover was mowed three times in April-July and the control was rotovated in early spring and late August. Ground beetles were captured in pitfall traps of 6.5 cm diameter in August-November with two traps per plot.
