Nearly 2000 introduced plant species are now established in the New Zealand wild - that's more than the number of native plants. Of these, more than 200 species have the potential to destroy native plant ecosystems.
Landcare Research scientists estimate more than 25 million native birds are killed annually by imported predators. To help combat this Greater Wellington Regional Council engages in systematic trapping and poisoning in Kāpiti, as do some community groups and landowners.
The Kāpiti Coast District Council controls pest animals and invasive weed species as part of managing ecologically significant sites, parks and reserves. Support, assistance and advice is also provided to landowners.
Species of particular concern include boneseed, German ivy, Cape ivy, English ivy, blue morning glory, tradescantia, wattle, Japanese honeysuckle, pampas, banana passionfruit, arum lily, Old Man's Beard, blackberry, cotoneaster, marram grass and climbing asparagus.
The Greater Wellington Regional Council has statutory responsibility for controlling pest animals, like Argentine ants, in the Wellington Region. If you're experiencing issues with Argentine ants, please contact GWRC, who can provide detailed advice on how to control the ants and monitor the spread (as outlined under the Regional Pest Management Strategy.)
