Observations on North-West European limestone grassland communities: Phytosociological and ecological notes on chalk grasslands of Southern England

  • J. H. Willems
Article

Summary

In 1970 chalk grasslands were studied in southern England, according to the principles of the French-Swiss School. The communities described belong to the associationCirsio-Brometum Shimwell 1971, emend., allianceMesobromion erecti (Br. Bl. & Moor 1938) Oberd. 1957, orderBrometalia W. Koch (1926 n.n.) Br.-Bl. 1936, of the classFestuco-Brometea Br.-Bl. 1936, emend. Tüx. 1961. Within theCirsio-Brometum three new sub-associations are distinguished: 1) subass. nov.anthoxanthetosum odorati; 2) subass. nov.Cornetosum sanguineae; and 3) subass. nov.campanuletosum rotundifoliae.

Special attention is paid to the relationship that exists between the management of these communities and the seral stages that lead to the development of serub following the decreasing influence of grazing.

Ulex europaeus scrub occurring on calcareous soil was also studied. The cryptogams of the chalk grasslands, mainly Musci, were investigated in detail.
