Download full pdf synopsis: RH3B
Silene uniflora, with its white and pale pink flowers, is the characteristic species of this simple, open community. Usually found with it is Euphrasia officinalis agg. or, fairly frequently, some sparse growth of Rumex acetosella or Rumex acetosa. There can be some presence of metalliferous bryophyes such as Cephaloziella stellulifera.
This community has largely been recorded from metalliferous spoil associated with old mine workings where the ground contains high concentrations of zinc, lead or copper. It has also been recorded from coastal shingle banks.
No sub-communities are described.
Community RH3A also occurs on mine spoil, but bryophytes are a much more important part of the flora there and Silene uniflora is infrequent. Community ST1C represents vegetation from shingle banks and Silene may be present there but Honckenya peploides is usually the dominant plant.
Most examples of this vegetation correspond to EU HD Annex I habitat 6130 Calaminarian grassland.
The mine-spoil aspect of this community is essentially unmanaged. Pressures include recreational activities and gradual succession to other vegetation types as metals are leached from the soil. Shingle bank examples may be threatened however by recreational pressure, mechanical beach cleaning and the creation of coastal defences which can interfere with sediment dynamics.
