Beavers Don’t Just Build Dams, They Build Nations

Gazing out the left-hand side of our boat, I caught my first glimpse of the rugged eastern perimeter of Wood Buffalo National Park in Alberta, Canada—a land saturated in superlatives.

Beyond the imposing stockade of white spruce and balsam, North America’s most expansive protected wilderness zone is filled with dense peat bogs called muskeg—a seemingly endless quilt of stagnant pools, waterlogged vegetation, and organic material in various states of decomposition. This malleable landscape, created through the retreat of melting glaciers, is virtually impassable by humans, but provides ideal conditions for other species to build on. A visiting Frommer’s writer once remarked, “Most of the animals here could easily live their entire lives without knowing humanity exists.”

Gifted with abundant resources and near-limitless freedom of action, the park’s residents have wide latitude to create the world they wish to inhabit. Around 1990, this freedom empowered a small number of beavers to create an entirely new pond. That purpose-built body of water would soon be expanded to 2,700 feet across—the length of nine football fields—with offshoots branching deep into the surrounding woods. At its center, a hardy lodge was constructed, from which the newly established territory would be vigorously maintained and defended.
