The bill aims to improve wildlife connectivity in Washington State by implementing a strategy to reduce wildlife-vehicle collisions and protect natural habitats. It emphasizes the importance of addressing the impact of vehicle collisions on wildlife populations and the economic costs incurred by residents. The legislation mandates collaboration between the departments of Fish and Wildlife and Transportation, along with stakeholders such as tribal governments and conservation organizations, to develop and regularly update the Washington Wildlife Habitat Connectivity Action Plan. This plan will focus on identifying and protecting wildlife corridors and constructing crossing structures to ensure safe passage for wildlife.

To facilitate these efforts, the bill establishes two new accounts: the Washington Wildlife Corridors Account and the Washington Wildlife Crossings Account, which will be funded through state appropriations and private donations. These accounts will support activities like land conservation, habitat restoration, and the design and construction of wildlife crossings, with a requirement for biennial reporting on expenditures to maintain transparency. Additionally, the bill amends existing law regarding the treasury income account, specifying that no appropriation is needed for payments to financial institutions and detailing the distribution of earnings to various accounts based on their average daily balance. Certain provisions of the bill are set to expire on July 1, 2028, while others will take effect on that date.
