Pay farmers to cover the cost of conservation measures (as in agri-environment schemes)
A 2004 analysis of monitoring data (a replicated site comparison) in the UK (Critchley et al. 2004) concluded that agri-environment schemes maintain, but do not reliably improve, plant diversity in grasslands. In 22 of 38 datasets, no change was detected in the vegetation under agri-environment schemes. Nine showed some change towards the desired plant community, and seven showed further deterioration. Of 17 datasets that included non-agreement land for comparison, seven found agri-environment agreements were benefitting plant communities (deterioration or no change on non-agreement land contrasting with maintenance or restoration on agreement land). Two found more positive trends in plant communities outside agri-environment schemes than under them. In eight comparisons, there was no difference between agreement and non-agreement land. Thirty-eight sets of vegetation monitoring results were analysed. They included 188 specific agri-environment schemes aimed at maintaining, enhancing or restoring grasslands or grassland landscapes in the UK. These involved repeated monitoring over up to eight years, on between four and 400 locations/agri-environment scheme, using a range of sampling strategies.
