Download full pdf synopsis: WE1B

 

Vegetation

This open weed community has a somewhat grassy aspect, with Poa annua a constant species and both Holcus lanatus and Agrostis stolonifera frequent, although none offer much cover. Cerastium fontanum and Stellaria media media are also constants. Frequently, one will encounter some Trifolium repens, Senecio vulgaris or Plantago lanceolata. A number of dock species are occasional 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 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 both Lolium spp. and Anagallis arvensis.

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.

 

Management

The persistence of this community is dependent on the regular trampling or the disturbance that comes with arable farming and gardening practices. Rarer archaeophytes have declined due to modernisation of these practices.
