The natterjack toad is the UK's rarest amphibian, confined to a few coastal and heathland sites. Conservation management of breeding pools directly improves individual amphibian welfare and population viability.
Natterjack toad conservation represents welfare action at the population level — each individual that successfully breeds and survives contributes to a population that can sustain itself. The species is so restricted that local extinction events have direct welfare significance. Conservation management that maintains warm, shallow breeding pools and controls competitor species directly enables successful reproduction and reduces individual mortality from failed breeding attempts.
