Books by Ellen Wohl

Saving the Dammed follows the course of the seasons throughout one representative year at a beaver meadow in Rocky Mountain National Park, Colorado. The seasonal changes provide a backdrop against which to explore how beavers change river valleys and how the decline in beaver populations has altered river ecosystems.

Explores the confluence of human and environmental change on ten of the great rivers of the world. Ranging from the Yellow River in China to Central Europe's Danube, this book shows us how pollution, such as in the Ganges and in the Ob of Siberia, has affected biodiversity in the water.
