WE1B Cerastium fontanum – Ranunculus repens weed community

Vegetation

This open weed community has a somewhat grassy aspect, with both Poa annua and Holcus lanatus constant species and Agrostis stolonifera frequent, although none offer much cover. Cerastium fontanum, Ranunculus repens and Trifolium repens are also constants. Frequently, one will encounter some Stellaria media, Bellis perennis, Taraxacum officinale agg. or Plantago lanceolata. A number of dock species are sometimes seen here: Rumex acetosella, Rumex obtusifolius, Rumex acetosa and Rumex crispus.

Ecology

This is a common weed community of fairly fertile, disturbed or trampled soils and is found in amenity grassland and growing amongst crops in arable fields, flower beds, and market and kitchen gardens.

Sub-communities

No sub-communities are described.

Similar communities

This is not the most distinct of communities, but from most other weed assemblages, WE1B may be distinguished by the frequency of Cerastium fontanum. That species is also a constant in the WE1D Lolium perenne – Anagallis arvensis weed community, but WE1B usually lacks Anagallis arvensis and Lolium spp. are only occasional.

Conservation value

Vegetation corresponding to this community is typically of relatively low conservation value. Segetal assemblages can contain archaeophytes such as Centaurea cyanus and Agrostemma githago which were once common sites of arable fields, but are now very rare. Species/64 m2 = 15.9, n = 71.

Management

The persistence of this community is dependent on regular trampling or disturbance. Rarer archaeophytes have declined due to modernisation of arable farming practices.
