Siliceous rocky slopes with chasmophytic vegetation
Siliceous rocky slopes with their chasmophytic vegetation (Androsacetalia vandellii). As a special case the chasmophytic vegetation on serpentinite belonging to the Asplenion serpentini is included. However, secondary communities of the Androsacetalia vandellii (in wall joints etc.) are not included.
Notes on habitat mapping
The precondition for assignment to this habitat type is the presence of vegetation of the syntaxa given above.
The entire area of the rock face that is free of woodland and scrub should be included if considerable sections host the relevant vegetation. Man-made rock faces which are subject to near-natural development (e.g. quarries) are included provided they host the relevant vegetation. However, secondary sites on walls and buildings are not included.
