What
Sika deer is recorded by a competent New Zealand authority as an introduced, invasive or managed threat subject.
Identification image pending
Why
The source identifies ecological, biosecurity or habitat risks that make this subject relevant to NZ Ex Games intelligence. Source context (Department of Conservation): Sika deer browse native vegetation and contribute to the wider introduced-deer effects of reduced understorey condition, altered plant abundance, soil disturbance, and impaired forest regeneration. Local effect depends on density, preferred browse plants, habitat, and co-occurring ungulates. No quantified sika-specific impact evidence is provided by the broad group source. Evidence limitation: Sika-specific vegetation-impact evidence.
Where
Distribution and current presence are place-specific and must be established from current authoritative or verified evidence.
