This report summarizes key achievements in 2017-2018 and outlines its path forward to achieving even more.

Economic Impact of Invasive Species Report

A 2017 report assessed the damages and potential impacts that could result if 23 of the state’s known 200 invasive species were allowed to spread in Washington in a single year without prevention or control measures. The report aimed to help state agencies better understand the cost of invasive species lost in jobs, wages, and business sales.

In terms of lost revenue and jobs, the report found that the state would lose $47.6 million in recreation, $100.5 million in water facilities, $282.9 million in livestock, $297 million in timber, and $589.2 million in crops.

Aquatic Invasive Species Funding Advisory Committee Report and Recommendations

In 2015, the state Legislature tasked the Washington Invasive Species Council with coordinating an advisory committee to develop recommendations for long-term funding to manage and prevent aquatic invasive species in Washington State. This report and its recommendations formed the basis for Senate Bill 5303-2017-18 and House Bill 1429-2017-18. This additional funding to the Washington Department of Fish and Wildlife Aquatic Invasive Species Unit is critical to the prevention and management of aquatic invasive species in Washington State.
