Beavers swimming, Acadia National Park, Maine

North American Beaver are the most noticeable species in the rodent family here. Like humans, they drastically modify their home environment by building dams and cutting down trees, creating wetlands and other habitats that are used by many other species. Walk around Jordan Pond, the Tarn or Witch Hole Pond to see chewed stumps and other signs of beaver activity. While beavers were almost trapped to extinction by the beginning of the 20th century, they've come back in force and can be found throughout the park.
