Utah State Noxious Weed Guide

This list of 54 noxious weeds is adapted from the State Weed Committee.

The plant species on this list are not native to Utah, are highly invasive, and are able to spread like wildfire throughout our ecosystems. Outside of their native origins, noxious weeds become oppressors with no known natural competitors to keep their populations in check. These silent invaders quickly begin to out-compete native plants, forever changing our landscapes. less ↑
