Diez años después de la eliminación de una presa en el río Elwha de Washington, la comunidad científica está documentando la exitosa historia de su restauración ecológica. La recuperación de las poblaciones de salmón está transfiriendo nutrientes críticos desde el océano hasta los bosques, a lo largo de las orillas del Elwha, enriqueciendo todo el ecosistema. El resurgimiento del Elwha está alentando a los conservacionistas a luchar por la eliminación de presas más grandes en la región y en el resto del mundo.
