How is the Colorado River restoring its ecosystem?
The Colorado River has been dammed, diverted, and slowed by reservoirs, strangling the life out of a once-thriving ecosystem. But in the U.S. and Mexico, efforts are underway to revive sections of the river and restore vital riparian habitat for native plants, fish, and wildlife.
How is the Colorado River Delta in Baja California?
The Colorado River delta in Baja California is now a mosaic of largely dried-up river channels and tidal salt flats. Ted Wood The Colorado River has been dammed, diverted, and slowed by reservoirs, strangling the life out of a once-thriving ecosystem.
