Download full pdf synopsis: RH1C



In this typically sparse wall community, Asplenium ruta-muraria is the sole constant species. This is frequently accompanied by tangled patches of the non-native Cymbalaria muralis. Occasional associates include the calcicole ferns Asplenium trichomanes and Phyllitis scolopendrium, patches of the moss Tortula muralis and another non-native, Centranthus ruber, which favours wall tops.


This is a familiar community that grows in dry crevices of lime mortar on lowland stone or brick walls



No sub-communities are described.


Similar communities

The same suite of calcicole ferns can occur in the RH1A crevice community and the RH1B pavement community. Those assemblages are much more species-rich, however, with higher bryophyte cover, and Cymbalaria does not occur in them.

Conservation value

Vegetation corresponding to this community is typically of relatively low conservation value.



This community does not require management.
