Amphibian decline is a problem of global importance, with over 40% of species considered at risk. This phenomenon is not limited to the tropics or to other countries. Amphibian species in the U.S. are also declining, contributing to the larger, global phenomenon. For example, in the State of Wyoming, the Wyoming toad has been extirpated in the wild and the boreal toad is a species of special concern. Understanding biotic and abiotic factors that influence amphibian persistence is critical for amphibian conservation. This work in northern Wyoming has focused on demography, habitat alteration and creation, and disease in the context of multiple amphibian populations. One of the foci has been to identify the capacity for mitigation wetlands [...]

Data were collected to inform conservation and management of amphibian populations. Information will be used to understand demographics of natural populations (survival, recruitment, and population growth rate), disease, and occupancy of amphibians across a landscape. Additional site specific data such as invertebrate species, calls of other organisms (i.e. birds), and vegetation will inform the implementation of mitigation (e.g. as required when amphibian habitat is destroyed during road construction, or possibly the creation of new amphibian-specific sites for reintroduction).
