Vegetation

Agrostis stolonifera is the main species of this marshy community, with Ranunculus repens, Galium palustre and Potentilla anserina being the only other constants. These are frequently accompanied by Cardamine pratensis, Filipendula ulmaria and Trifolium repens, and less often by Mentha aquatica, Leontodon autumnalis and Senecio aquaticus. The community differs from others in this group (GL2) in its higher forb component and the presence of more species tolerant of seasonal flooding. Calliergonella cuspidata tends to be the only bryophyte. The vegetation is typically calf-height.

 

Ecology

The Agrostis stoloniferaRanunculus repens marsh-grassland is a variable grouping of vegetation from mesotrophic, wet grassland and marsh on gleys and basin peats in the lowlands. Soils are relatively base-rich, quite fertile and fairly organic.

 

Sub-communities

Two sub-communities have been described. The Holcus lanatus Juncus effusus sub-community (GL2Ai) is the more typical and variable sub-community whilst the Potentilla anserina Carex hirta sub-community (GL2Aii) represents wetter, seasonally inundated and probably trampled vegetation.

 

Similar communities

This community differs from the closely related GL1B Agrostis stoloniferaFilipendula ulmaria marsh-grassland in being species-poor, more fertile, and also more heavily grazed.

 

Conservation value

This is a species-poor grassland community. A limited number of examples with good cover of plants such as Filipendula ulmaria, Iris pseudacorus and Equisetum fluviatile may correspond with EU HD Annex I habitat 6430 Hydrophilous tall herb.

 

Management

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