The Hawaii House of Representatives has introduced House Bill 1220, aimed at combating the invasive majano anemone, a species threatening the fragile coral ecosystems of Kaneohe Bay. Introduced on February 10, 2025, the bill seeks to implement a multi-phase removal strategy proposed by the Department of Land and Natural Resources' Division of Aquatic Resources.

The majano anemone, which has spread over approximately 950 square yards in Kaneohe Bay, poses a significant risk to native coral species, particularly the endemic finger coral, Porites compressa. Known for its rapid growth and aggressive competition for space, the anemone has previously caused ecological shifts in other regions, such as the Philippines and Vietnam, where it outcompeted native corals. If left unchecked, it could lead to a decline in reef health, negatively impacting marine biodiversity and the coastal communities that rely on these ecosystems for their livelihoods.

Key provisions of HB1220 include support for chemical control methods and physical removal practices to mitigate the spread of the anemone. The bill reflects a growing concern among lawmakers and environmentalists about the ecological integrity of Hawaii's marine environments.

Debate surrounding the bill has focused on the effectiveness and potential environmental impacts of the proposed removal methods. Some stakeholders express concerns about the use of chemical controls, advocating for more research into their long-term effects on the ecosystem. However, proponents argue that immediate action is necessary to prevent further degradation of the coral reefs.

The implications of HB1220 extend beyond environmental concerns, as healthy coral reefs are vital for local fisheries and tourism, both significant contributors to Hawaii's economy. By addressing the invasive species issue, the bill aims to safeguard these economic interests while preserving the state's unique marine biodiversity.

As the legislative process unfolds, the bill's progress will be closely monitored by environmental advocates and local communities, who are eager to see effective measures implemented to protect Hawaii's precious coral reefs from invasive threats.
