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.
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.
Vegetation corresponding to this community is typically of relatively low conservation value.
This community does not require management.
