Just substitute Kaipātiki for Whaingaroa/Raglan because volunteers are working here too. We are a small but mighty group.
Most of New Zealand's pest plants originally come from tropical and subtropical parts of the world. Many were introduced historically as garden plants, and they thrive in New Zealand's warm, frost-free climate, particularly in Auckland and Northland. A substantial proportion of DOC-listed environmental w**ds, National Pest Plant Accord species and regionally managed pest plants come from warm climates such as tropical South America, Africa and Southeast Asia, with vigorous vines, shrubs and aquatic plants especially prominent. While no agency provides an exact figure, the prevalence of warm-origin species across national and regional lists indicates that at least 60% of New Zealand's pest plants likely derive from tropical or subtropical regions. As temperatures continue to rise with climate change, New Zealand is expected to become even more hospitable to these species, increasing the risk of further spread, including potential migration into cooler regions such as the South Island.
This is why the work of community groups like PFK matters more than ever. Through regular w**d monitoring and control across Kaipātiki, volunteers are on the frontline of keeping these species in check. By removing established pest plants and preventing new ones from taking hold, this mahi directly protects the native species that make our local ecosystems resilient, and gives them the best possible chance of adapting to a changing climate. Every volunteer hour spent pulling w**ds is an investment in the long-term health of Kaipātiki's environment.
