The deadly fungal disease Bd (Batrachochytrium dendrobatidis) is a major cause of the wave of recent extinctions of frogs and toads, but it is difficult to decide how to best save amphibian populations from its ravages. Now a new framework has been developed that helps managers decide which actions are the most beneficial. A combination of a model of multiple boreal toad breeding sites, and expert judgment, was used to assess 35 possible actions that either preserve habitat, reduce Bd prevalence, or reintroduce boreal toads to areas where they no longer exist. The resulting strategy balanced toad survival against cost, and was predicted to reduce toad decline from 53% over 50 years to 21%. The paper, coauthored by SAFS professor Sarah Converse, appears in Conservation Letters.
