Lizard’s tail

Saururus cernuus

What

Lizard’s tail is recorded by a competent New Zealand authority as an introduced, invasive or managed threat subject.

Why

The source identifies ecological, biosecurity or habitat risks that make this subject relevant to NZ Ex Games intelligence. Source context (Auckland Council): It can dominate the herb layer of wetlands, marshes, swamps, streams and lake edges, potentially shading out submerged species. Auckland also identifies prevention of recreational use of ponds as an operational/amenity impact.

Where

Distribution and current presence are place-specific and must be established from current authoritative or verified evidence. Habitat context (Auckland Council): Wetlands, marshes, swamps, streams and lake margins. Habitat suitability is not evidence of current local presence.
