Efforts to remove invasive giant reed in Arizona rivers and lakes continues with Department of Forestry grants
A giant reed that can grow 4 inches per day is choking Arizona rivers, creeks, and lakes. The stubborn Arundo donax plant, an invasive species brought to the U.S. from Southeast Asia, is wreaking havoc in about 30 mostly warm-weather states in the South and West, including Arizona. According to the University of California, Riverside Center for Invasive Species Research, Arundo was first planted in California in the 1820s to provide roofing and erosion control in the Los Angeles area.
