The natterjack toad is Britain's rarest amphibian, restricted to coastal dunes and heathlands, where dedicated conservation work has stabilised but not reversed its long decline.
Natterjack toads face multiple welfare threats including habitat loss, pool desiccation during drought, and the chytrid fungus Batrachochytrium dendrobatidis. Breeding pools in coastal dune systems are vulnerable to succession and sea level change. Individual toads suffer high mortality in years when pools dry before metamorphosis is complete. Conservation management including pool creation and vegetation management directly improves individual welfare prospects. The species' restricted distribution makes every population critical, and local extinctions represent irreversible welfare and conservation losses.
