Water voles (Arvicola terrestris) and common voles (Microtus arvalis) cause substan-tial damage in organic fruit growing by gnawing at bark and roots of trees. To prevent the immigration of voles into orchards a mechanical drift fence was developed and successfully tested in 2002 and 2003. The effectiveness of the drift fence, consisting of wire mesh reaching 30 cm above the soil surface and up to 30 cm into the ground, was impaired by moles (Talpa europaea) undermining the fence. Voles used these tunnels to immigrate into the protected plots. In a new study supported by “Bund-esprogramm Ökologischer Landbau” and carried out between 2004 and 2006, factors contributing to undermining of drift fences by moles were determined. The results of practical field... |
