Why
The source identifies ecological, biosecurity or habitat risks that make this subject relevant to NZ Ex Games intelligence.
Where
Distribution and current presence are place-specific and must be established from current authoritative or verified evidence. Habitat context (Waikato Regional Council): Ponds and other still or slow-moving freshwater habitats; its documented ornamental-pond pathway is particularly relevant to private ponds and water gardens. Habitat suitability is not evidence of current local presence.
