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.
