Wild Wednesday - Sand lizard
The sand lizard, scientific name, Lacerta agilis, is one of the UK's rarest reptiles, found only in a few select heathland and coastal dune habitats. In the South Downs National Park, efforts to conserve this elusive species are ongoing, particularly in heathland areas like East Weavers Down, part of the Woolmer Forest Site of Special Scientific Interest (SSSI). These habitats provide the sandy soils and open vegetation that sand lizards need for basking, hunting insects, and laying eggs.
Sand lizards are distinguishable by their vibrant green flanks (especially in males during the breeding season) and their preference for sunlit, undisturbed areas. They are highly sensitive to habitat disturbance, which is why conservation efforts focus on maintaining and restoring heathland environments.
Here are some facts about this wonderful reptile:
- the sand lizard is one of the UK's rarest reptiles and is protected under the Wildlife and Countryside Act 1981 and listed as a European Protected Species
- they dig burrows for shelter and hibernation, sometimes within rabbit warrens - these burrows can be up to one metre deep
- like many lizards, they can shed their tails to escape predators-a process known as autotomy
- they primarily eat insects and spiders, but may also consume flowers or even their own young in extreme condition
- females lay eggs in warm sand during June and July, and the young hatch after one to two months
- many live only five to eight years, but can survive up to 20 years in the wild
One key aspect of protecting sand lizards - and other vulnerable wildlife in the South Downs, is responsible dog walking. The South Downs National Park Authority's Take the Lead campaign urges visitors to keep dogs on leads, especially from March to September. This is the breeding season for many ground-nesting birds and reptiles like the sand lizard. Dogs roaming off-lead can trample nests, disturb basking lizards, or even cause fatal injuries.
By keeping dogs on leads and sticking to marked paths, visitors help safeguard these rare creatures and support the park's broader biodiversity goals. It is a simple action that makes a significant difference in preserving the delicate balance of this unique landscape.
