Semi-natural habitats help keep pests and weeds in check

Conserving semi-natural habitats such as forests, hedges and semi-natural permanent grasslands can be beneficial to the natural enemies of crop pests and weeds, and thus help farmers indirectly. A large international consortium involving INRA researchers (1) has shown that when it comes to landscape composition and the affect it has on the natural regulation of pests and predators, responses vary widely. The studies also showed that landscape alone is not in itself an efficient means to regulate crop pests.
