The ongoing biodiversity crisis and increasing land pressure call for efficient strategies that promote biodiversity and sustain ecosystem services while minimizing trade-offs with agricultural production. Here, we examine how the concurrent implementation of two agri-environmental interventions—flower strips and extensively managed meadows—can synergistically enhance wild bees in agricultural landscapes through three nonexclusive mechanisms: (i) habitat heterogeneity, (ii) resource complementarity, and (iii) resource continuity. We sampled plantbee interaction networks and nest-site availability across all major habitat types in 28 Central European agricultural landscapes to assess landscape-level bee community composition and the spatiotemporal distribution of resources. Landscapes combining both intervention types showed a synergistic increase in wild bee abundance, including key crop pollinators. Consistent with habitat heterogeneity effects, bee species turnover was higher between different intervention types than between patches of the same type, resulting in increased species richness in landscapes with both interventions. Bee communities in landscapes with flower strips were dominated by smaller and more oligolectic species, whereas higher proportions of extensively managed meadows were associated with lower functional specialization and a more balanced bee community composition, likely reflecting alleviated environmental filtering. Extensively managed meadows provided suitable nesting habitat for ground-nesting bees and both interventions independently increased bees’ foraging generality toward a broadened diet, indicating resource complementarity. The bees’ extinction risk from agricultural landscapes was also reduced by both interventions, likely through measured staggered flowering periods that increased resource continuity. Overall, our findings demonstrate that combining complementary agri-environmental interventions can increase land-use efficiency and enhance ecosystem services by more effectively promoting wild pollinators, thereby reducing trade-offs between biodiversity conservation and agricultural production.
