International Beaver Day is celebrated every year on April 7.

According to Beavers: Wetlands & Wildlife, Beaver Day is “a great time to lead a hike to a beaver pond, arrange a library display, or give a program about this amazing animal. Beavers are more than fascinating watchable wildlife—they can help us solve major environmental problems…Beaver dams restore wetlands, those ‘rainforests of the North’ rated as the land’s best life support system.”
