Invasive Stinknet Spreads Across Arizona

A non-native plant known as “stinknet” is causing concern across Arizona, with Valley cities requesting public assistance to prevent its further spread. The plant, while visually resembling wildflowers, negatively impacts the local environment.

What is Stinknet?

Stinknet earned its name from its strong, unpleasant odor, often described as similar to turpentine or a skunk. Researchers believe the plant arrived in Arizona as early as 2015 through its potent seeds. The current warm and dry conditions across the state have contributed to its rapid expansion.

Environmental Impact

Challie Facemire of the Central Arizona Conservation Alliance explained the plant’s detrimental effects. “It’s not good habitat or food for any of our wildlife, so it’s not helpful there either,” Facemire said. Stinknet competes with native desert plants by stealing nutrients and can choke out existing vegetation.

Wildfire Risk

As stinknet dries, its reddish flowers become highly flammable, posing a significant risk as wildfire season approaches. The plant’s seeds also spread easily, exacerbating infestation and the distinctive smell.

How to Help Control Stinknet

The Arizona Department of Agriculture has already designated stinknet as a noxious weed. The city of Tempe is urging residents to carefully remove the plant while wearing gloves. They recommend bagging the plant to prevent seed dispersal and disposing of it in the trash.

Removal Tips

“Not too bad to pull out,” Facemire noted, adding, “If you can, it’s easiest just to pull it.” The Central Arizona Conservation Alliance offers a guide to identifying and managing other invasive plants on their website. This story was originally reported by ABC15’s Jordan Bontke.
