Seven tweetable facts about beavers
First launched in 2009 by a non-profit organization called Beavers: Wetlands & Wildlife (BWW), International Beaver Day celebrates the rodent’s environmental contributions and its important role in landscapes.
The dams that beavers build can in turn create and restore wetlands, which protect and filter our drinking water, provide wildlife habitats, store flood waters to reduce property damage and maintain surface water flow during droughts. Beavers were once endangered throughout much of their range, but have made a remarkable comeback over the last century. In Canada, they can even be found in rivers and creeks within many major cities.
BWW declared April 7 International Beaver Day to honour Dorothy Richards, also known as the “Beaver Woman,” whose birthday fell on the same day. Before her death in 1985, Richards studied beavers for 50 years, had two consecutive beaver families living in an addition to her house and wrote a book called Beaversprite: My Years Building an Animal Sanctuary.
