Story: Life in fresh water

Floating fern

Floating fern

The native floating fern retoreto (Azolla rubra) forms reddish mats that cover Motuoapa Swamp near Lake Taupō. Many of New Zealand’s aquatic native plants have been replaced by exotic species. Azolla rubra is a notable exception. In fresh water such as Lake Taupō introduced plants have largely replaced native plants at depths of 2–10 metres.
