Grassland biodiversity in managed landscapes is threatened by land-use intensification, but is also dependent on low-intensity management. Solutions that allow for both agricultural production and species conservation may be realized either on individual grasslands, by adjusting management intensity, or at the landscape level, when grasslands are managed at different intensities. Here we use a dataset of more than 1,000 arthropod species collected in more than 100 grasslands along gradients of productivity, to assess the reaction of individual species to changes in productivity. We defined a range of land-use strategies and evaluated their effects on overall production and on species abundances. We show that conservation of arthropods can be improved without reducing overall production. We also find that production can be increased without jeopardizing conservation. Conservation and production could, however, not be maximized simultaneously at the landscape level, emphasizing that management goals need to be clearly defined.     «
