Annex I habitats that are a primary reason for selection of this site

  • Winterton – Horsey Dunes is the only significant area of dune heath on the east coast of England and also includes areas of acidic dune grassland as an associated acidic habitat. The contrast with the nearby calcareous and species-rich dunes of north Norfolk is marked. The Atlantic decalcified fixed dunes (Calluno-Ulicetea) vegetation is characteristic of dune heath in an eastern locality with low rainfall. The drought-resistant grey hair-grass Corynephorus canescens is a characteristic species of the open dry dune soils.

  • The slacks within Winterton – Horsey Dunes are chiefly of interest because they occur on an extremely base-poor dune system on the dry coast of East Anglia in eastern England. Because of their acidic soils, the dunes support swamp and mire communities, in addition to small areas of typical dune slack vegetation characterised by creeping willow Salix repens ssp. argentea with Calliergon cuspidatum and Yorkshire-fog Holcus lanatus. As a result they represent an extreme of the geographical range and ecological variation of Humid dune slacks within the UK.
