Dry sand heaths with Calluna and Genista (Inland dunes, old and decalcified)
Dry heaths on decalcified or calcium-poor inland dunes dominated by dwarf shrubs (Calluna vulgaris, Genista anglica, Genista pilosa) usually with scattered scrub. Semi-natural formation created through sheep grazing or historically through scraw cutting or burning.
Notes on habitat mapping
The criterion for the delimitation of this habitat type is the presence of Calluna vulgaris and/or Genista anglica, Genista pilosa dominated heathland vegetation on inland dunes. Smaller, level sites in between dunes hosting the relevant heathland vegetation are included. Small patches of wet heaths of dune slacks are also included. Scrub encroachment or uncontrolled grass growth up to a maximum of 70% may be tolerated. Where Empetrum nigrum is dominant the stand is to be considered under the habitat type dry sand heaths with Calluna and Empetrum nigrum (2320). Stands on coastal dunes are to be considered under Atlantic decalcified fixed dunes (Calluno-Ulicetea) (2150).
Comments
All stages of dwarf-shrub communities including those which have already been partly encroached upon by scrub should be included. Dwarf-shrub communities with Genista germanica (31.222 and 64.1 x 31.22) are highly endangered and should absolutely and explicitly be included.
