Résumé :	Several farmland bird species have undergone serious population declines during the past 30 years. Evidence from national monitoring schemes co-ordinated by the British Trust for Ornithology indicates that agricultural intensification has been responsible for these losses. A range of factors, including a decrease in the acreage of spring cereals, the loss of rough grazing, an increase in intensively managed silage and in livestock density, and the overall lack of crop diversity, have coincided with population declines of several species. Owing to the wide range of species affected and the multiple factors underlying the declines, it is difficult to identify those individual aspects of farm management which are of most importance to the recovery of farmland bird populations.We suggest that a general extensification of agriculture, affecting a range of management practices, rather than implementation of management prescriptions for individual species, will be most likely to benefit farmland bird communities.This could be achieved through agri-environment schemes in conjunction with widespread initiatives to reduce the intensity of farm management over large areas.
