Classed by the SPNR as a heath with 'scarce plants'. The site marked in the SPNR documents is an area of enclosed farmland close to Nansavallan Wood near Truro. In their book 'Time and Fragile Nature: Rothschild's Reserves and what became of hem'', Miriam Rothschild and Peter Marren suggest that this is a mistake and that the site in question is actually Carrine Common - a mile away. This is a typical cornish heathland also with hay meadows and wildlife-rich hedgerows. It is designated a SSSI.
