Frensham Common

Frensham Common is a large Site of Special Scientific Interest (SSSI) heathland of 922 acre which includes two lakes; it is owned and operated by the National Trust.

Terrain, plants and animals
Frensham Common is an English SSSI heathland of 922 acre which includes two large lakes; it is owned by the National Trust and managed by Waverley Borough Council. It lies almost wholly within Frensham, Surrey, a nucleated village on alluvial soil narrowly buffered to the north-west, connected by a path. The local road network surrounds the site; the nearest trunk roads are 5 mi away. The elevation is low but undulating with high points near the Kings Ridge - which bisects the common along a north/south axis - at approximately 90 m above sea level (ASL) and nearby, to the south-east, the three Devil's Jumps, the highest of which is 126 m ASL. The common supports few streams due to the permeability of the soil, although the ground to the south-east, called the Flashes, is boggy.

The site supports several protected species, including sand lizard, smooth snake, woodlark, Dartford warbler and nightjar.

The heathland is at risk of fire when conditions are dry. In 2010, 86 acre of the common, in very dry conditions, burned. The most recent serious fire was in May 2023 when approximately 10 hectares (25 acres) burnt.

The lakes are prone to blooms of Blue-Green Algae in the summer months. Once detected by the Environment Agency, the National Trust warns visitors to avoid entering the pond water.

Lakes
Until the construction of reservoirs and a gravel extraction-related lake in the north of Surrey in the early 20th century, Frensham Great Pond was the largest lake in the county. The Great Pond and Frensham Little Pond were built during the Middle Ages to provide fish for the Bishop of Winchester's estate. They were developed by Bishop Henry of Blois, also known as Henry of Winchester, who established Farnham Castle to the north and who owned this and nearby manors.

Tourism
The area is popular with visitors, particularly in summer months. Swimming is supported at the Great Pond within marked areas. Both ponds have car parking, toilets, cafés and picnic areas. Parking at both ponds carry charges, but payment can only be made digitally.

During hot weather in 2018 large numbers of visitors flocked to Frensham Common, particularly Frensham Great Pond, causing an anti-social parking problem with cars parked on rural clearways, double yellow lines and also leaving behind large amounts of rubbish.

Frensham Great Pond supports a sailing club, with dinghies regularly visible on the water. A hotel adjoins the south side of the Great Lake by the yachting area. North west of the common border is the small village of Frensham, which adjoins two hamlets further across the River Wey.

Less than 5% of the Common is within spurs of the common in Churt to the south or Tilford to the north.

Four prehistoric bowl barrows are in a straight line in the centre-east of the common. Villagers termed these the King's Ridge Barrows.

Wartime
During the Second World War, tanks based in the Headley area used Frensham Common for training, whilst Canadian soldiers used to gallop across the Common. At this time, Frensham Great and Little Ponds were drained as otherwise they would have provided markers for German bombers.

Filming
The common, particularly Frensham Great Pond, is a popular filming location alongside local Bourne Woods and Hankley Common.
