The bill establishes bull kelp forests as the official state marine forest of Washington, recognizing their ecological, cultural, and economic significance. Bull kelp, along with other marine vegetation, plays a crucial role in supporting diverse marine species and sustaining important fisheries. The legislation emphasizes the cultural importance of bull kelp to tribal nations, affirming that the act respects and upholds the treaty rights of these communities. It also highlights the recent decline of bull kelp in Puget Sound and the state's commitment to conservation efforts, including a goal to recover at least 10,000 acres of kelp forests and eelgrass meadows by 2040.

To formalize this recognition, the bill adds a new section to chapter 1.20 RCW, designating bull kelp (Nereocystis luetkeana) forests as the official marine forest of Washington. This designation aims to raise awareness of the importance of bull kelp forests to the state's identity and ecology, while also driving collaborative efforts for their preservation and restoration.
