There is compelling evidence that more diverse ecosystems deliver greater benefits to people, and these ecosystem services have become a key argument for biodiversity conservation. However, it is unclear how much biodiversity is needed to deliver ecosystem services in a cost-effective way. Here they show that, while the contribution of wild bees to crop production is significant, service delivery is restricted to a limited subset of all known bee species.

Bees provide essential pollination services that are potentially affected both by local farm management and the surrounding landscape. To better understand these different factors, they modelled the relative effects of landscape composition , landscape configuration and farm management, and their interactions, on wild bee abundance and richness for 39 crop systems globally.
