American Beaver: here’s the scoop


Following overexploitation for the fur trade, protection and re-introduction programs have re-established the American beaver throughout its historical range. Now abundant, beavers are still hunted and trapped for pelts. Many beavers are killed in areas where tree felling and dam building are in discordance with human development. They are also highly sensitive to tularemia, an infectious disease.
