Weeds in New Zealand are usually introduces plants that have escaped a garden setting and are now wild. Invasive weeds are destroying our native plant communities and transforming the natural landscapes that make New Zealand unique.
We need to work together to remove the weeds from private and public land, as the problem will get worse if there is no action.
As weeds spread across our landscapes they:
- Create a fire risk.
- Can cause acidification of soils which leads to the depletion of some minerals in the soils.
- Use more water, so runoff is decreased which affects streams and associated fauna in the water catchment.
- Provide habitat for exotic pest plants, animals and diseases.
- The fast growth rates of for example wilding pines allow them to out compete and suppress low-stature native vegetation.
We are guided by the Regional Pest Management Plan 2018, the Biosecurity Operational Plan 2018-2028 and the Biosecurity Act 1993.
