Pest plants are one of the greatest threats to New Zealand’s parks, reserves, coasts, bush remnants, wetlands and alpine areas. Some plants are unwanted organisms and banned from sale, propagation and distribution in New Zealand. See the list of Banned Species on the Weedbusters site below and find out how to control different pest plants here.
Invasive weeds are destroying our native plant communities. This invasion is transforming the natural landscapes that make New Zealand unique. It's also killing the native animals that depend on those habitats.
In native forests, wilding conifers compete for space with native trees and plants and don't provide the advantages that native trees do, such as food for native birds or insects. Their needles form an acidic carpet which discourages regeneration of native forest floor species.
