The bill seeks to improve wildlife connectivity in Washington State by creating a strategic framework aimed at reducing wildlife-vehicle collisions and safeguarding natural habitats. It mandates collaboration between the departments of Fish and Wildlife and Transportation, along with various stakeholders, to develop and regularly update the Washington Wildlife Habitat Connectivity Action Plan. This plan will identify essential wildlife corridors and propose funding strategies for projects that ensure safe wildlife passage across highways, thereby enhancing public safety and preserving the state's natural heritage.

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 treasury appropriations and private donations. Expenditures from these accounts will support land conservation, habitat restoration, and the construction of wildlife crossing structures. Additionally, the bill amends existing legislation regarding the treasury income account, eliminating the requirement for appropriations for payments to financial institutions and ensuring that earnings are distributed appropriately among various state accounts based on their average daily balances. The bill also introduces expiration dates for certain provisions and emphasizes compliance with the state Constitution regarding the allocation of treasury earnings.
