Abstract/Summary

Success in reintroducing amphibians may be more context- than detail-dependent such that a slavish adherence to protocol may not foster success better than a more intuitive approach. We provide two reintroduction case studies for boreal toads where the approach was different, but where both resulted in gains in understanding, including first estimates of survival for boreal toads from a reintroduced population. Given the effects of disease on amphibian populations and the potential for disease to remain in a system after extirpation, there is a need to restructure reintroduction guidelines. Maintaining populations on the landscape through reintroductions provides an opportunity for the development of resistance and may facilitate species persistence into the future. But to be effective, care in understanding the context of the reintroduction and a re-envisioning of guidelines is necessary.
