Invasive species in New Zealand
This article is licensed under the GNU Free Documentation License. It uses material from the Wikipedia article "Invasive_species_in_New_Zealand".

New Zealand's short human history has resulted in a number of serious plant and animal pests. These pests threaten the economy due to the impact on agriculture and also threaten the country's biodiversity.

Invasive plants are classified as such on a regional basis with some plants declared as national plant pests.
