There is a wide range of pest plants in Otago, a lot of them are escapees that were brought in to New Zealand for people’s gardens but jumped the fence and spread across our landscapes causing trouble for our native biodiversity.

Not all garden escapees are included in our pest plan for various reasons but that doesn’t mean they’re not weedy. Weedbusters has a lot of information or various pest plants and if you’re having trouble identifying a plant, iNaturalist is tool that allows you to add observations and have experts identify it for you.

What's the difference between a pest plant and a weed?

Read our Pest versus Weed factsheet to see how we decide what is a pest plant under our Regional Pest Management Plan.
