Grassland as meadow and pasture was formerly abundant on all clay soils in Lincolnshire, notably in the coastal marshland, the central clay vale and parts of the Trent Vale. However it has declined massively from over 230,000 ha (est.) in 1938 to 49,000 ha (est.) in 1995. Within Lincoln the South and West Commons account for a large proportion of the City's extant semi-natural grassland, at least part of which is neutral. Cemeteries, railway embankments and landfill sites can, if treated appropriately, provide good additional grassland habitat.
