Unintentional effects of environmentally-friendly farming practices: Arising conflicts between zero-tillage and a crop pest, the common vole ( Microtus arvalis ).

•Common voles only detected in zero-tilled plots within an experimental design.•No voles detected in either reduced or conventional tilled plots.•Zero-tillage offers low disturbance habitat, often with established cover.•Fallow and vetch plots had highest occupancy, while no voles detected in pea plots.•Crop nitrogen content not a predictive quality for common vole habitat choice.
