Dense thickets of salt cedar infest the banks and the riverbed of the Little Colorado River April 11 in Winslow, Ariz. The salt cedar, an invasive plant species, will be mostly removed during the Winslow Flood Control Project. According to the U.S. Forest Service, salt cedar disrupts and replaces native plants, degrades native wildlife habitats, drains limited area moisture, and increases wildfire risks.
