Influence of “soil-vegetation-farming practices” system on the population dynamics of the fossorial form of the water vole (Arvicola terrestris sherman) in Franche-Comté, France.
Small mammals are the most important vertebrate pests in Central European agriculture. In French mid-altitude mountains, cyclic outbreaks of Arvicola terrestris populations have caused dramatic grassland damage since the 1970s. One possible explanation is that intensive agriculture has created homog...

Small mammals are the most important vertebrate pests in Central European agriculture. In French mid-altitude mountains, cyclic outbreaks of Arvicola terrestris populations have caused dramatic grassland damage since the 1970s. One possible explanation is that intensive agriculture has created homogeneous grassland ecosystems with a high risk of outbreaks. While the role of the landscape structure on A. terrestris outbreaks has been identified on a large scale, little is known about the quantitative effects of grassland management on a local scale. We aimed to investigate the impact, on a parcel scale, of soil, vegetation and farming practices on the A. terrestris population dynamics. We examined different phases of an A. terrestris population cycle in agricultural parcels : low density, increase and high density. For each parcel, relative densities of A. terrestris were estimated by an index method.
