Cerne and Sydling Downs
When undertaking an appropriate assessment of impacts at a site, all features of European importance (both primary and non-primary) need to be considered.
Annex I habitats that are a primary reason for selection of this site
|6210 Semi-natural dry grasslands and scrubland facies on calcareous substrates (Festuco-Brometalia) (* important orchid sites)|
|This site consists of a large area of semi-natural dry grassland on the west Dorset chalk. Dry valley slopes with a variety of aspects support extensive examples of CG2 Festuca ovina – Avenula pratensis grassland in the south-west of its UK range. A particular feature of this site is the presence of the Succisa pratensis – Leucanthemum vulgare sub-community, especially on south- and west-facing slopes. This type of calcareous grassland is almost entirely restricted to parts of Wiltshire and Dorset. On south-west-facing slopes, the nationally scarce dwarf sedge Carex humilis can be abundant in this sub-community.|

Annex II species that are a primary reason for selection of this site
|1065 Marsh fritillary butterfly Euphydryas (Eurodryas, Hypodryas) aurinia|
|This site supports a large marsh fritillary Euphydryas aurinia metapopulation composed of two large and one smaller sub-populations which regularly expand into other nearby areas in favourable years. These colonies occupy calcareous downland situations and complement the wet grassland habitats of the other Dorset strongholds.|
