My first book, Eager: The Surprising, Secret Life of Beavers and Why They Matter, was published in 2018 (Chelsea Green). It was named one of the year’s best books by outlets including the Washington Post, and received the PEN/E.O. Wilson Literary Science Writing Award.

It’s available at these and other retailers:

“A marvelously humor-laced page-turner about the science of semi-aquatic rodents… Goldfarb has built a masterpiece of a treatise on the natural world.” — The Washington Post

Eager reveals that our modern conception of a natural landscape is wrong, distorted by the trapping of millions of beavers from North America’s lakes and rivers. The consequences of losing beavers were profound: streams eroded, wetlands dried up, and species from salmon to swans lost vital habitat.

Today, a growing coalition of “Beaver Believers” — including scientists, ranchers, and passionate citizens — recognizes that ecosystems with beavers are far healthier than those without them. From the Nevada deserts to the Scottish highlands, Believers are now restoring these industrious rodents to their former haunts.

Eager is the powerful story of how one of the world’s most influential species can help us fight drought, flooding, wildfire, extinction, and climate change — and how we can learn to coexist with our fellow travelers on this planet.
