In the regions where agriculture covers most of the landscape, species rich field margins have an important role in the preservation of biodiversity, plants and fauna. Considering this, the Swiss Confederation plans to introduce «field margins» as new type of ecological compensation area. It is a perennial and linear structure sown with a mixture of native forbs and grasses. It is 3 to 12 meters width and is made to endure throughout the years without reseeding. To determine the effect of this new structure on Vole and Mole populations, 36 agricultural fields were studied with either an improved field margin, a usual field margin or a wild flower strip on the edge. The results show that these three types of field edges are appreciated by voles, but their activity inside the field stay low, whatever the edge type. Not a single Mole has been observed during this study.
