This class occurs mainly in boundaries or by hedges between crops but<br />
occasionally beside grassl<strong>and</strong>, small patches or other linear features on brown<br />
soils. If the vegetation is a hedge, then hawthorn (Crataegus monogyna) is the<br />
usual species, <strong>and</strong> the ground cover is usually common couch (Elymus repens),<br />
nettles (Urtica dioica), cleavers (Galium aparine) or barren brome (Bromus<br />
sterilis). It is a quite common class <strong>and</strong> not diverse, with plants such as<br />
creeping thistle (Cirsium arvense), cock’s-foot (Dactylis glomerata) <strong>and</strong> white<br />
dead nettle (Lamium album) as characteristic species. This class occurs widely<br />
throughout lowl<strong>and</strong> Britain except the extreme south-west of Engl<strong>and</strong>.<br />
