Area: 89.1 hectares.
Site boundary extended.
Previously part of the Red Moor–Breney Common SSSI. Part of the site is a Nature Reserve of the Cornwall Trust for Nature Conservation.
Description and Reasons for Notification:
Red Moor exhibits a wide variety of habitats from dry heath to bog and open-water located in a large valley basin some 3 kilometres to the north west of Lostwithiel. The site lies on the contact zone between the Hensbarrow Downs granitic intrusion and the Devonian Meadfoot Beds although the bedrock is mostly covered with superficial alluvial gravels and peat deposits. Parts of the area were worked for alluvial tin until the end of the 19th century.
The northern parts of the site are mainly dry dwarf-shrub heath dissected by a complex of open-water habitats. Much of the low lying basin to the south consists of acidic marshy grassland and wet heath merging into Sphagnum dominated bog. There are also areas of mixed deciduous woodland and willow Salix carr.
The site possesses a rich and varied flora with good assemblages of bog asphodel Narthecium ossifragum, cottongrass Eriophorum vaginatum, marsh cinquefoil Potentilla palustris and bog mosses Sphagnum spp. Other species of note include white sedge Carex curta, climbing corydalis Corydalis claviculata, petty whin Genista anglica and pillwort Pilularia globulifera. Royal fern Osmunda regalis grows extensively on this site and in places forms an understorey in the willow Salix carr. The woodland areas also possess a rich lichen flora including Usnea articulata.

The ponds and ditches support some 13 species of dragonfly and damselfly including the nationally rare scarce blue-tailed damselfly Ischnura pumilio. Red Moor is of particular importance for aquatic beetles including the very scarce Hydrochus nitidicollis. Two uncommon spiders Pirata piscatorius and Hypselistes jacksonii have also been recorded at this site. Breeding bird species include nightjar Caprimulgus europaeus, tree pipit Anthus trivialis, willow tit Parus montanus and sparrowhawk Accipiter nisus.
