New Government Strategy Targets Harmful Caulerpa Seaweed to Protect Coastlines

Biosecurity Minister Andrew Hoggard announced a new government strategy to combat the harmful exotic Caulerpa seaweed, focusing on prevention, detection, removal, research, and coordination. With $31.7 million invested, efforts including ultraviolet light irradiation and chlorine enclosures have achieved up to 90% biomass reductions at key sites, prompting further research into these successes. The strategy emphasizes national collaboration among iwi, councils, fishers, and communities to protect New Zealand's coastlines through continued tool refinement, elimination trials, and strengthened surveillance.
