General Information

Caulerpa (Caulerpa taxifolia) is a highly invasive green alga that can cause major ecological and economic damage.

The most likely way of caulerpa arriving into New Zealand is though it being imported for use in aquariums.

If caulerpa is released into New Zealand marine environments there is a high risk of it establishing, as aquarium strains in particular are highly successful in a wide range of environmental conditions.

It is also possible that caulerpa from its natural (tropical) range can adapt to cooler environments and become invasive.
