Data-Driven Invasive Weed System

Old Man’s Beard (Clematis vitalba)

I’m about to begin working with Hutt City Council to develop an invasive weed data collection and visualisation system. Invasive weeds in Aotearoa/New Zealand pose a significant threat to native ecosystems, agriculture, and biodiversity. Introduced species like wilding pines, old man's beard, and woolly nightshade outcompete native plants, alter habitats, and disrupt natural food chains. These weeds spread aggressively, often with the help of wind, water, or human activity, making control efforts challenging. Conservation groups, government agencies, and local communities work together to manage invasive weeds through eradication programs, biological control, and public awareness initiatives. Protecting native flora requires ongoing vigilance and coordinated action to prevent further ecological damage.

The data collection and visualization system will consist of ESRI Field Maps apps, QuickCapture, AGOL dashboards and interactive web maps, built with Experience Builder. This system enables council staff and contractors to efficiently record weed infestations in the field, track control efforts, and visualize data through interactive maps. By integrating real-time reporting and spatial analysis, decision-makers at the council can prioritise high-risk areas and allocate resources effectively. Labour hours and tracklines will be recorded, enabling the council to track resource allocation for each Land Management unit and weed species. This system will enhance weed management strategies, supporting a more coordinated and data-driven approach to protecting Hutt City’s natural environment. I look forward to getting started with this important work in March.
