There are two local nature reserves managed by Waverley Borough Council, they are Rowhill Copse north of Farnham and The Flashes, between Hindhead and Frensham.
Rowhill Copse, straddling the Surrey and Hampshire border, is an area of mixed woodland with hazel and sweet chestnut coppice. There is also a field, ponds, streams, a bog and an area of heathland. The head of Blackwater stream is to the Surrey side. There are several entrances into the reserve and a path for people with special needs that can be reached via Parkland Grove (off Weybourne Road) at the eastern end of the reserve.
The Flashes is a part of Frensham Common's heathland area, which also includes the small series of hills called The Devil's Jumps. The Local Nature Reserve is part of the much larger Thursley, Hankley and Frensham Commons Site of Special Scientific Interest (SSSI) and part of the Wealden Heaths Special Protection Area (of European importance) for its bird, reptile and invertebrate populations.
Thursley Common is one of Surrey's three National Nature Reserves. The Flashes LNR is largely a river valley mire dominated by purple moor-grass, cross-leaved heath, common cottongrass, ling, rushes and Sphagnum mosses. The bog on The Flashes contains an important area of peatland.
