Our campaign to tackle the invasive Taiwan cherry (Prunus campanulata) continues to gain momentum. It’s good to see more people understanding the serious ecological risk this species poses.
We want to take a moment to thank everyone who has supported our efforts so far. Because of your cooperation, there are now no known Taiwan cherry trees south of Kohatu – a major milestone and testament to the progress we’ve made.
But our work isn’t over yet – under the Nelson-Tasman Regional Pest Management Plan, Taiwan cherry is targeted for eradication.
Originally sold by nurseries for its decorative value, and often mistakenly marketed as sterile, Taiwan cherry has proven to be highly invasive.
From late July to early September, it produces thousands of bright pink flowers that attract pollinators. Birds such as waxeyes, starlings, blackbirds, and kererū then eat the fruit and disperse the seeds widely through their droppings.
The seedlings are shade-tolerant and fast-growing, allowing them to invade native forests and scrublands. Once established, they outcompete native species, disturb natural regeneration, and alter ecosystems. Seedlings form deep roots, making manual removal difficult, while mature trees require chemical treatment to prevent regrowth.
If you planted a Taiwan cherry on your property before 2019, our Biosecurity team will remove it at no cost, and reimburse up to $75 for a suitable replacement tree.
