Natterjack toads are one of the UK rarest amphibians, restricted to coastal dunes and heathlands, and depend on the creation and maintenance of shallow, warm breeding ponds.
Natterjack toads at degraded sites face chronic welfare pressures through failed breeding attempts in unsuitable pools and reduced population viability. Adults returning to breeding sites only to find pools dried up prematurely or choked with vegetation experience the energetic cost of breeding attempts without reproductive success. Population fragmentation means that individuals at isolated sites face greater inbreeding depression and disease risk. Habitat restoration through pool creation and management directly improves breeding success, reducing the stress of repeated failure and supporting healthier, more genetically diverse populations.
