Mountain ranges, and specifically the montane habitats they contain, can support a unique flora and fauna. They receive the same statutory protection as other nationally important sites in England. The Cumbria High Fells for example has 110 Sites of Special Scientific Interest (SSSI) that cover about 18 per cent or 35,852 hectares (ha) of the area. The majority of this SSSI area (31,286 ha) is also designated under the Habitats Regulations as ‘Special Areas of Conservation’ (SAC).
