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.

Marta

La marta europea (Martes martes) está clasificada como En Peligro Crítico (CR) en la Lista Roja de la UICN. Enfrenta un riesgo extremadamente alto de extinción en estado silvestre debido al severo declive poblacional y la pérdida de hábitat.
