Nonnative plants can be described as out-of-control “biological wildfires,” an Arizona Department of Forestry and Fire Management official says.
By Breanna N. Steele Cronkite News PHOENIX – A giant reed that can grow 4 inches per day is choking Arizona rivers, creeks and lakes.
Willie Sommers, invasive plant program coordinator for the Arizona Department of Forestry and Fire Management, says nonnative plants can be described as out-of-control “biological wildfires.” His program provides grants to groups working to remove destructive plants, including Arundo, and is responsible for prioritizing invasive plant treatment.
When Arundo grows, it creates a root base around native plants, causing an uplift by raising plants and disrupting the natural floodplain, said Lauren Monheim, program manager for Watershed Management Group’s River Run Network. “It also changes how a river flows because it creates a thick wall, making the water squeeze through a smaller gap.”

The water will help it regrow fast and start new growth in another part of the river.Watershed Management Group has a program called the River Run Network that removes Arundo around creeks and rivers.
Watershed Management holds volunteer sessions every Saturday morning through May to remove the giant reed along the Tanque Verde Creek. After volunteers collect the Arundo in giant trash bins, the canes are donated to places to use for fencing and even to feed someone’s lucky goats.
