Tree-of-heaven
Spotted lanternfly is likely to infest tree-of-heaven if it arrives. Historically, tree-of-heaven was introduced for ornamental purposes, but is now listed as a Class C noxious weed in Washington due to its negative impacts. Tree-of-heaven is rapid-growing and crowds out native and desirable plants. Mapping known tree-of-heaven populations allows Washington to plan control efforts, keeping our state safe from this invasive pest.
