If you are a hiker, a birdwatcher, a biker, or otherwise enjoy getting out in Washington's forests, meadows, and deserts, you may see invasive species such as common crupina, garlic mustard, knapweeds, leafy spurge, or yellow starthistle. Or, if you’re camping out and lighting a fire at the end of the day, your firewood could be a temporary home to non-native wood-boring insects.
What can you do to prevent the introduction and spread of invasive species?
Don't move firewood. To avoid introducing non-native insects and diseases from your firewood, buy your firewood near where you plan to burn it.
- Obtain your firewood near where you camp. Firewood that is produced locally has less risk of introducing new pests and diseases to an area.
- If you bring firewood when camping, burn all of it. The longer it remains on the ground, the more chance that a pest or disease can move from the firewood into the living trees nearby.

Clean cars, equipment, personal gear, and animals. To prevent invasive species from hitching a ride as you move through natural areas, you can take the following actions:
- Regularly inspect and remove caked-on soil and seeds from vehicle tires and undercarriages of any vehicles or equipment that moved between potentially infested and uninfested areas. See:
- Inspection and Cleaning Manual for Equipment and Vehicles to Prevent Invasive Species
- Vehicle Cleaning Technology for Controlling the Spread of Noxious Weeds and Invasive Species
- Limit your travel through infestations, particularly when seeds are viable.
- Brush off or wash dogs that have been out running around natural areas.
- Before and after traveling through natural areas, inspect and brush your footwear and clothing clean of caked-on soil and seeds, especially if you knowingly walk through an area of heavy invasive species infestation. See: Brush Off Invasive Species
- Wear gaiters to prevent sticky seeds from getting stuck in your socks.
- Shake out your tent, camp chairs, sleeping bags, and other accessories before leaving a campsite to remove any plant or seed materials.

Report and help eradicate invasive species and promote native and desired species.
- Report invasive species online.
- Learn to identify invasive species, using resources such as the Washington Noxious Weed Control Board's Guides for Identifying Weeds.
- Join in local weed pulls and volunteer to monitor for these species. For example, you could volunteer:
Use certified weed-free feed for your animals. You can:
Use certified weed-free feed. In particular, feed weed-free forage for several days before transporting stock to new locations. For information about the state and federal programs, see:
