The decline of this once common bird was due to changes in land use, in particular the decline in mixed farming and the resulting loss of the former patchwork of arable and grassland areas (4). Furthermore, other agricultural changes have affected this species, including the use of fertilisers, denser production of crops, sowing seeds in autumn and winter and the increase in silage production (4).
Conservation action has not been targeted at this species as yet. Ten percent of the British population presently occurs on sites that are designated as Special Protection Areas (SPAs). The species is monitored well at wetland sites, but the majority of the population on agricultural land is not sufficiently monitored. This is a key issue that is being addressed at present; good monitoring of populations allows conservationists to track the well-being of populations and can indicate when and where conservation action is needed (5).
