摘要
In Louisiana, Castor canadensis (North American Beaver) rarely occur in coastal marshes and are far more common in forested wetlands. We recently observed a North American Beaver lodge in a coastal marsh that was constructed partly of commercial lumber, possibly made available by recent hurricanes. The animals may have used lumber for lodge construction due to the dearth of trees or other woody vegetation in coastal marshes. This observation points to the adaptability of North American Beaver when choosing materials for lodge construction.
