Download full pdf synopsis: SC1A
This community consists mainly of thorny mixes of Prunus spinosa, Crataegus monogyna and Rubus fruticosus agg. with clambering stems of Hedera helix and, beneath, some straggling Galium aparine. Rosa canina, Ulex europaeus and Urtica dioica can be frequently added to the rather unfriendly list of species. The ferns Polystichum setiferum and Pteridum aquilinum are also frequent, as is some weak growth of Agrostis stolonifera.
Most records of this community come from hedgerows and hedgebanks in the lowlands, but it also occurs as scrub, invading abandoned fields and fringing woodland. Due to its thorny and rather commonplace nature, it has been vastly under-recorded.
No sub-communities are described.
Community SC1B is similar in character, but lacks Prunus spinosa.
Vegetation corresponding to this community is typically of relatively low conservation value.
Hedgerows would once have been periodically layed to maintain their vigour and make them stockproof. Today, the vast majority of hedges are mechanically flailed. Hedgerows and scrub may be lost due to enlargement of fields, agricultural improvement and urban developments.
