What we do Conservation Our reserves Gong Hill Size: 5ha Ownership: ARC and private owners Designation: SSSI Restrictions: Open access land. Please keep dogs on a lead. Access: Layby off Old Frensham Road Grid ref: SU 85302 43393 Gong Hill is a small, but very important lowland heathland reserve, supporting one of Surrey’s few original native sand lizard populations The reserve Gong Hill is designated as a Site of Special Scientific Interest, because it supports one of the last native populations of sand lizards in Surrey. Although present at other sites in the county, these are often the result of reintroductions after the original populations became extinct. Gong Hill typifies dry lowland heathland, dominated by common heather, the vegetation is interspersed with bell heather and wavy hair-grass with occasional stands of gorse and dwarf gorse. Common dodder – a curious plant, parasitic to other plants, can also be found here. Areas of scrub fringe the site creating a transitional zone between heath and woodland that benefits a wide range of species. An area to the south-west of the main site is in the process of restoration after becoming overgrown with pine regrowth. With the heavy shade removed, the heather is in the process of recovering. A sand lizard sanctuary Sand lizards have very specific habitat requirements. As well as dense dwarf shrub at ground-level, sand lizards require areas of exposed sand for egg-laying. Eggs are laid into sandy burrows of between 4 and 10cm deep, which are dug by the females, and are then covered over to leave no trace for potential predators. At Gong Hill, areas of vegetation are cut on regular cycles to maintain these bare, sandy areas and ensure this rare species can continue to thrive. What to see Native Surrey sand lizards. During the breeding season, males sporting their dark-green flanks look particularly handsome. Adders, grass snakes, slow worms and viviparous lizards can also be seen basking in sunny areas. Groups of crossbills flitting between the pine trees. A specialist feeder on conifers, crossbills have a distinctive overlapping bill, so they are able to pry open cones and eat the nutritious seeds.
