Taiao Environment

An Organism of Interest (OOI) is a species that is capable of causing adverse effects, particularly to biodiversity values. It warrants being watch-listed for ongoing surveillance or future control opportunities, but has not been given the status of pest in our Otago Regional Pest Management Plan (2019-2029).
