International Beaver Day

Every year on April 7, the hardest-working rodent in the wetlands gets a standing ovation. International Beaver Day celebrates the beaver, nature's original civil engineer, and the remarkable woman who spent half a century studying it. Every April 7, the day shines a light on the dams, lodges, and ponds that beavers build, and on the wetlands full of life that rise up behind them.

Hike to a pond or stream with friends, photograph signs of beaver work, and compare finds over hot chocolate afterward.

The longest known beaver dam, in Wood Buffalo National Park in Alberta, Canada, stretches about 850 meters, more than eight football fields.
