Beavers: Boreal Ecosystem Engineers


  • Focuses specifically on landscape and ecosystem alteration by beavers

  • Provides a cohesive reference useful to wetland scientists, ecosystem and landscape ecologists, wildlife managers, and students

  • Contains many potential applications to natural resource management in boreal regions, including how beaver activity affects water storage, sediment and nutrient transport, and the availability of wetlands as wildlife habitat

About this book


This book integrates the results of Dr. Carol Johnston’s research on beaver ecosystem alteration at Voyageurs National Park, a mature beaver-altered landscape named after the French-Canadian voyageurs who transported packs of beaver pelts through the region more than 250 years ago. The text synthesizes information about the vegetation, soils, and chemistry of beaver impoundments, bridging the fields of ecosystem science and landscape ecology to analyze the dynamics of a beaver-altered landscape. The findings from this mature system can inform other scientists and managers about the sustainability and long-term ecosystem effects of beaver activity that is still expanding in much of North America. These findings are also compared to studies of beaver-occupied landscapes in other locations, including the Adirondacks, Tierra del Fuego, and other national parks.

Dr. Carol A. Johnston is Professor of Ecology in the Department of Natural Resource Management at South Dakota State University. She is a Certified Professional Soil Scientist, a Fellow of the Society of Wetland Scientists, and a life member of the Ecological Society of America.
