 Biosecurity New Zealand reports that NIWA’s team of divers recently completed some inspection dives in Aotea Great Barrier waters to check how effective a salt treatment has been and to gauge the current state of the incursion.
The team checked the plots in Whangaparapara and Tryphena where they had applied a thick layer of coarse salt back in December. Overseas this has proved the most effective treatment option available. In both areas, no Caulerpa was seen inside the treated areas whereas extensive Caulerpa cover was visible outside the treatment plots. This seems to demonstrate that the salt treatment works, however we are still waiting on a final report on just how effective it’s been.
