Introduced invasive weeds such as wild ginger,oldman's beard, Japanese honeysuckle, and wandering willie can degrade your native habitat by smothering and competing with native plants.

It's a good idea to eliminate invasive weeds before you begin planting an area with native plants, and follow up weeding each year to ensure the pest plants don't reinvade.

Most regional councils can help with advice and have publications they can send you about identification and control of pest plants.

Dealing with animal pests

Introduced animal pests such as possums, cats, pigs, hedgehogs, ferrets, stoats, weasels and rats have a detrimental effect on native wildlife.

Introduced pests raid birds' nests and eat eggs and chicks, and even kill adult birds.  They also compete with native species for food sources such as flowers, leaves, seeds and berries, and can lead to the collapse of forest ecosystems.

If you have pest animals in your area, you should seek expert advice from your Regional Council Biosecurity (Pest Plant and Animal) Officer. Many regional councils also provide pest traps.
