Animal reintroductions: An innovative assessment of survival.

Highlights: [•] Animal reintroductions will likely increase though quantitative and interim evaluations of progress are rare. [•] Adaptive management requires such assessments which are critical in redefining efforts to meet circumstances and budgets. [•] Results from an ongoing reintroduction effort of Boreal Toads illustrate how intermediate results can inform next steps. [•] We used a novel application of multistate robust design to estimate early-stage survival and quantify interim success. [•] We illustrate the efficacy of this method and the value of such information within an adaptive management framework. [ABSTRACT FROM AUTHOR]
