The natterjack toad is the UK's rarest amphibian, confined to isolated coastal dune and heathland sites where its specific habitat requirements can be met.
Natterjack toad welfare is inseparable from habitat quality. Their highly specific breeding pool requirements mean that changes to coastal hydrology, scrub encroachment over heathland, and habitat fragmentation directly reduce breeding success. Breeding failures cause nest abandonment and population-level reproductive failure. Climate change is creating both opportunities (warmer springs aiding breeding) and threats (drier summers causing pool desiccation before tadpoles metamorphose). Active habitat management — scrape creation, pool maintenance, and scrub control — is essential for maintaining the microhabitat conditions that allow normal reproduction and welfare.
