Does Wales Have Lizards?

Published in Welsh Wildlife 3 mins read

Yes, Wales is home to several species of lizards, which are fascinating reptiles that can be found in various habitats across the country.

Lizards are cold-blooded creatures that rely on external heat sources to regulate their body temperature, often seen basking in sunny spots. While relatively few species are native to the United Kingdom, Wales provides suitable environments for some of these remarkable reptiles.

Native Lizard Species in Wales

Two primary species of lizards can be found in Wales: the Common Lizard and the rarer Sand Lizard.

Common Lizard (Zootoca vivipara)

The Common Lizard, also known as the Viviparous Lizard, is the most widespread reptile in the UK and is commonly found throughout Wales. They are highly adaptable and inhabit a variety of environments, including:

  • Grasslands
  • Moorlands
  • Heaths
  • Woodlands
  • Coastal dunes

These small lizards typically grow up to 15 cm in length and have varying patterns of brown, grey, or olive green, often with darker spots or stripes. Unlike most reptiles, common lizards give birth to live young, rather than laying eggs, which is an adaptation to cooler climates. They are often seen scurrying away quickly when disturbed or basking on rocks, logs, or pathways to warm up.

Sand Lizard (Lacerta agilis)

The Sand Lizard is one of the UK's rarest reptiles, and its presence in Wales is particularly significant. Confined to a few precious sites, primarily within sandy heathland habitats and sand dunes, this beautiful lizard is a species of high conservation concern.

Key characteristics and facts about the Sand Lizard:

  • Habitat Preference: They strongly favour sandy heathland and sand dune environments.
  • Basking Behavior: Sand lizards can frequently be spotted basking on bare patches of sand, utilizing the warmth to regulate their body temperature.
  • Appearance: Males are typically vibrant green during the breeding season, especially on their flanks, making them quite striking, while females are more subtly coloured with brown and grey patterns.
  • Conservation Status: Their range has been severely reduced due to the destruction of their specific habitats, making them a protected species. Conservation efforts are crucial to safeguard their remaining populations.

Where to Spot Lizards in Wales

If you're hoping to observe lizards in Wales, consider visiting protected areas and nature reserves that offer suitable habitats. These sites often have management plans in place to support reptile populations. Look for sunny, open areas with plenty of ground cover for shelter.

Tips for spotting lizards:

  • Choose a warm, sunny day: Lizards are most active when the sun is out, particularly in the morning or late afternoon.
  • Be patient and quiet: Approach potential basking spots slowly and avoid making sudden movements.
  • Look low: Lizards blend in well with their surroundings, so scan the ground, rocks, and logs carefully.
  • Respect their space: Observe from a distance to avoid disturbing them.

The presence of these fascinating reptiles contributes to the rich biodiversity of Wales, highlighting the importance of conserving their natural habitats for future generations.
