They broke the levees to save the wetlands—and nature staged a 'miracle' comeback in just three years.

In 2008, Point Reyes breached levees to restore Giacomini wetlands. This project reconnected dairy pastures to tidal influence, allowing natural processes to reshape the land. Within three years, the endangered tidewater goby expanded into newly restored tidal channels and Lagunitas Creek. The National Park Service said this rapid expansion was notable.
