Invasive and noxious weeds in Arizona are more than just pesky plants – they are downright destructive.
"We've got all the really nasty weeds in Arizona," said Larry Howery, noxious weeds/range management specialist with the UA College of Agriculture and Life Sciences Cooperative Extension. "Everybody should be concerned. The economic and ecological impacts are tremendous."
Howery said some non-native plants were introduced as ornamentals, like fountain grass and twisted barrel. Others – like buffelgrass – were introduced as food for livestock. Whether it is buffelgrass, camelthorn, toadflaxes, purple loosestrife, leafy spurge or another type of invader, these weeds threaten agriculture, wildlife and human health by ruining highways and making great fuel for wildfires.
