Invasive species are defined by Oregon Statute as ‘nonnative organisms that cause economic or environmental harm and are capable of spreading to new areas of the state.’
— ORS 570.750

Invasive species are animals, plants, and microorganisms that are not native to Oregon and once here can reproduce so vigorously that they replace our native species. They pose a threat to key sectors of Oregon's economy that depend upon natural resources and native ecosystems. Agriculture, forestry, tourism, and water resource infrastructure, including hydropower facilities, are at serious risk of being adversely impacted by invasive species. Unchecked, invasive species individually and collectively have the potential to imperil public health and to transform ecosystems, resulting in widespread economic and environmental devastations.


Clean Drain Dry


Protect Oregon’s Waterways

CLEAN all aquatic plants, animals and mud from your vehicle, boat, motor or trailer and discard in the trash. Rinse, scrub or pressure wash, as appropriate, but away from storm drains, ditches or waterways.

DRAIN live wells, bilge and all internal compartments.

DRY your boat between uses, if possible. Leave compartments open and sponge out standing water.

Aquatic life need water to survive. Invasive freshwater mussels are a particular threat because they can close their shells and survive out of water for a long time.
