Washington’s Integrated Approach to Preventing and Addressing Invasive Species  

Invasive species, whether aquatic or terrestrial plants, animals, insects, or pathogens, threaten Washington’s community health, recreational opportunities, agriculture, and other economic and environmental factors. At a national level, the costs to prevent, monitor, and control invasive species, combined with the damage to crops, fisheries, forests, and other resources, cost the nation an estimated $1.2 trillion over the past 50 years. Closer to home, the introduction and spread of just 22 invasive species in Washington equates to more than $1 billion in damage and loss.
