In this study, conservation biologists used a Delphi survey to identify focal species for a wildlife conservation plan in a rapidly suburbanising area of the USA. Beavers were amongst the species identified. The survey method - and the conservation efforts it was trying to support - faced several challenges, including lack of data and extreme economic pressures to develop land.

This study assessed a relocation programme of 234 beavers in Wyoming, USA, between 1994 to 1999. Populations were successfully established at 13 out of 14 sites, but significant proportions of the relocated beavers died. Beaver age was an important factor in survival rate. The study shows that planning for losses from mortality and emigration is crucial for successful relocation.

This book discusses the reintroduction of beavers in Britain. The text covers beavers' biology, environmental impact, and reintroduction process. It provides insights into their history and behaviour, and has been praised for its engaging writing style. Please note, this resource is not open-access.

This experiment tested the tolerance of willows and cottonwoods to flooding. Willows thrived whilst cottonwoods struggled after prolonged flooding. These results were consistent with observations in a beaver pond. Understanding these tolerances was said to be able to help with ecosystem restoration plans.

This study compared three sections of a German mountain stream: sections affected by beavers and a free-flowing section. It found that beavers increased the diversity of habitats and insects in the ecosystem. The beaver dam itself had the highest density of insect species. The dam structure is also analysed in the text, describing how one very thick piece of beaver-cut alder was essential to the overall structure. Please note, this resource is not open-access.
