Forests aid biological control in coffee plantations

Preserving remnants of the forest in agricultural landscapes supports biodiversity conservation and the provision of agriculturally-relevant ecosystem services such as pollination or biological control. In Brazil, scientists Medeiros et al. recently found that forests in the surrounding landscape reduce the occurrence of a widespread economic pest in sun-coffee monocultures by enhancing natural enemy diversity. Remnants of the forest maintain a permanent reservoir of natural enemies and therefore, these habitats should be protected.
