Photographs Page 3 Summary The Mid Cornwall Moors SSSI is notified under section 28C of the Wildlife and Countryside Act 1981 (as amended). The site supports a diverse mosaic of semi-natural habitats, including heaths, fens, grasslands, woodlands, scrub and species-rich hedgerows, with ponds and waterways. It is of special interest for the following nationally important features that occur within and are supported by the wider habitat mosaic: • wet and dry lowland heathland; • lowland fens (including habitats often referred to as mires, swamps and bogs); • wet and dry broad-leaved woodlands; • species-rich neutral grasslands; • an assemblage of nationally rare and nationally scarce flowering plants and ferns; • populations of Cornish eyebright Euphrasia vigursii, coral-necklace Illecebrum verticillatum, chamomile Chamaemelum nobile, lesser butterfly-orchid Platanthera bifolia, chaffweed Centunculus minimus, lesser water-plantain Baldellia ranunculoides and allseed Radiola linoides; • marsh fritillary butterfly Euphydryas aurinia; • assemblage of invertebrates chiefly associated with scrub heath-moorland; • populations of the water beetle Hydrochus nitidicollis, the mud snail Omphiscola glabra and the slender amber snail Oxyloma sarsii; • breeding willow tit Poecile montanus; and • geological features that demonstrate the mineralisation which occurs at the latest stage of granitic emplacement. Parts of the previously notified Goss and Tregoss Moors SSSI, Breney Common SSSI and Red Moor SSSI are not considered to be of special interest. Accordingly, these areas are proposed for denotification under Section 28D of the Wildlife and Countryside Act 1981, as inserted by Schedule 9 to the Countryside and Rights of Way Act 2000. Page 4 1.
