Water hyacinth is recorded by a competent New Zealand authority as an introduced, invasive or managed threat subject. Source context (Ministry for Primary Industries): Free-floating freshwater rosette; shiny rounded leaves. Mature leaves commonly have conspicuously swollen/inflated leaf stalks; flowering plants produce showy lavender-purple flowers with a yellow-marked upper petal. MPI’s core field description is the free-floating rosette of shiny rounded leaves.
The source identifies ecological, biosecurity or habitat risks that make this subject relevant to NZ Ex Games intelligence. Source context (Ministry for Primary Industries): Free-floating rosettes can form dense mats that smother waterways and native vegetation, lower water quality and dissolved oxygen, obstruct dams and irrigation, provide mosquito-breeding habitat, and pose drowning/access risks to people and animals.
