The common lizard is one of the UK's most widespread reptiles, dependent on warm, sheltered heathland and grassland habitats where welfare depends on thermoregulation opportunities and invertebrate prey availability.
Common lizards require access to thermal gradients to regulate their body temperature behaviourally. Heathland degradation through succession to rank grass or scrub without management removes the warm, open basking sites they need. Cat predation is a significant direct welfare threat in gardens and suburban heathland edges. Loss of invertebrate diversity reduces food availability. Conservation management including scrub control and creation of south-facing banks provides the structural diversity common lizards need for thermoregulation and foraging.
