The bill aims to improve wildlife connectivity in Washington State by addressing wildlife-vehicle collisions and habitat fragmentation due to human development. It establishes a strategy involving the departments of Fish and Wildlife and Transportation to identify and protect wildlife habitat connectivity corridors. The bill emphasizes the construction of wildlife crossing structures, which can reduce collisions by up to 90%, and encourages collaboration with tribal governments, federal agencies, and conservation organizations to secure funding and prioritize projects that facilitate safe wildlife passage.

To support these initiatives, the bill creates two new accounts: the Washington Wildlife Corridors Account and the Washington Wildlife Crossings Account, which will receive appropriations from the general fund and other sources for land protection, habitat restoration, and wildlife crossing construction. The bill also amends existing law regarding the treasury income account, specifying that no appropriation is required for payments to financial institutions and that these payments will occur before the distribution of earnings. It mandates the state treasurer to distribute earnings monthly, ensuring that various accounts receive their proportionate share, while also including provisions for the expiration of certain sections by July 1, 2028, and compliance with constitutional requirements regarding treasury accounts.
