These cereal crops habitats are modified to such a degree, i.e. by spraying with pesticides, genetic modifications and intensive land-use, that few other plants, pollinators or birds can coexist with them. The species of plant formerly associated arable habitats are now the most rapidly declining species in Europe, with similar declines seen in farmland birds and soil invertebrates. Modified cereal crop habitats cover a significant area of Wales but now support little or no associated biodiversity interest .
