As a response to concerns for the conservation of pollinator diversity, mitigation measures are being initiated in the Netherlands by a wide variety of organizations and private individuals. Most of these efforts focus on the restoration of floral resources, by sowing wildflower mixtures and/or improving terrain management. Such initiatives are, however, rarely part of a coherent management plan at landscape scale, even though connectivity between both new and existing habitat patches is essential to improve effectivity for bee conservation, as flight ranges of many bee species are limited to hundreds of meters. Here, we show some first results from an initiative in which a wide variety of stakeholders, including e.g. local governments, nature managers, farmers and scientists have joined forces to increase floral resources in the Geuldal area (Southern Limburg, the Netherlands) in order to promote bee populations, with a focus on bumblebees. Effects of five different types of habitat measures (e.g. sown wildflower strips and alternative pasture and hedgerow management) are being monitored by comparing plant and bee diversity in comparison to control sites both within and without the Geuldal area.
