Castor Americano

El roedor más grande de América del Norte, el castor canadiense puede pesar hasta 32 kg y es un maestro ingeniero del ecosistema que habita ríos, lagos y humedales de Canadá y el norte de Estados Unidos. Al talar árboles y construir presas de hasta cientos de metros de longitud, los castores crean estanques que proporcionan hábitat para cientos de especies. Sus madrigueras y canales transforman cuencas hidrográficas enteras. Una vez casi cazados hasta la extinción por su piel, las poblaciones de castor se han recuperado notablemente.
