Vegetation

The sward of this wet grassland community is comprised mainly of Holcus lanatus, Juncus acutiflorus, Anthoxanthum odoratum, Juncus effusus and Cynosurus cristatus. The forb component is low growing and consists mostly of Trifolium repens, Ranunculus acris, R. repens and R. flammula, with Cardamine pratensis, Galium palustre, Prunella vulgaris and Cirsium palustre also frequent. The bryophyte layer is quite distinctive, with Rhytidiadelphus squarrosus being abundant and sometimes forming a carpet with Calliergonella cuspidata and Brachythecium rutabulum.

 

Ecology

The Juncus acutiflorusRhytidiadelphus squarrosus grassland is found on wet, rather acidic peaty gleys of rather low fertility. It is a lowland farmland community of sloping ground.

 

Sub-communities

No sub-communities are currently described for this community.

 

Similar communities

This grassland is more species-rich and less rank than the other main Juncus acutiflorus sward, community GL1A, and also differs in that small sedges are more frequent in the present community, mainly Carex nigra and C. panicea. It differs from the similar GL4D Agrostis canina/vinealisRhytidiadelphus squarrosus, in that indicators of upland dry-humid grassland, such as Potentilla erecta, Hylocomium splendens and Luzula multiflora, are less frequent, whilst marsh plants such as Galium palustre, Cardamine pratensis, Ranunculus flammula and Ranunculus repens are more frequent.

 

Conservation value

This is a fairly species-rich grassland community of which a low proportion of examples correspond with EU HD Annex I habitat 6410 Molinia meadows.

 

Management

These swards are managed as rough grazing land (typically for cattle). The main threats to these grasslands include improvement, abandonment and afforestation.
