2020 Washington Invasive Species Council Biennial Report

This report summarizes key achievements in 2019-2020 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.

Early Detection and Rapid Response Best Practices

A global review of peer-reviewed publications and government-produced response plans related to invasive species response and management identified best practices for invasive species emergency response. Furthermore, the report provides a framework for any type of invasive species response, which functions as a baseline for responding to unanticipated invasive species or for the development of new species-specific response plans. In addition to the report, a recorded Webinar has been published online.

State Interagency Feral Swine Response Plan

The Washington State Invasive Species Council, Washington State Department of Fish and Wildlife, and Washington State Department of Agriculture, in cooperation with the U.S. Department of Agriculture, Animal Plant Health Inspection Service, Wildlife Services plan and response strategy to reduce the environmental and economic harm caused by feral swine in Washington State.
