If you work in Washington's forests, you may see a variety of invasive species, such as garlic mustard, knapweeds, or Scotch broom. The health of the trees you work with may be affected, or be threatened, by gypsy moths or invasive wood-boring insects.
What can you do to prevent the introduction and spread of invasive species?
Clean vehicles, equipment, and personal gear. To prevent invasive species from hitching a ride on you or your gear, 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 travel through infestations, particularly when seeds are viable.
- Inspect and brush your footwear and clothing clean of caked-on soil and seeds, particularly if you knowingly walk through an area of heavy invasive species infestation.
