Summary
Plant species growing on wet cliffs are exposed to very specific ecological conditions. They occur on north-faced, very damp, dripping, overhanging or vertical calcareous rocks, in shady places. Species are mainly hygrophytic and shade-resistant. Communities are rich in ferns and mosses, on the more constantly watered places also green and blue-green algae occur. The habitat is strongly depending on the period of watering and appears on very small areas.
The habitat is found in temperate and in Mediterranean regions. In many sites, the areas of the habitat are very small and isolated. Wet cliffs of the Macaronesian islands are considered under habitat H3.3.
Indicators of good quality:
Main threats are various human activities that change the water regime. The following characteristics may be considered as indicators of good quality:
- species richness of the cliffs and presence of the characteristic species
- presence of habitat rare species at their typical frequency
- constant supply of water
