Sometimes protecting Washington’s forests, waterways, wildlife, and public lands starts with just one person noticing something unusual.One photo. One report. One early detection before a species spreads further.Not every invasive species introduction makes headlines at first. Many begin quietly—a plant along a trail, an unfamiliar insect in the garden, a mussel attached to a boat, a strange crab in a trap.That’s why public reporting matters so much.Every report helps experts better understand what’s happening across the state and where action may be needed most. In some cases, early reports have helped slow or prevent impacts before they became much larger and more expensive problems.You don’t have to be a scientist to help protect what you love.You just need to notice, document, and report: https://invasivespecies.wa.gov/report-a-sighting/ Image courtesy of Washington State Parks ...
