Project Data

The Nelson City Council Waterworks Reserves Pest Plant Management Programme, operating in the Maitai and Roding River catchments, is an ongoing project that began in 2008/2009. Its primary objective is to control invasive pest plants that threaten the integrity of the natural ecosystems within the reserves. The long-term goal of achieving a Forest Protection basis, where the area is free from the impacts of transformational pest plants. The programme follows the Forest Restoration Framework (FRF), a clear and systematic approach specifically designed by Kaitiaki o te Ngahere for site-led and weed-led restoration projects. This framework categorises management areas or pest plant populations into distinct phases based on operational progress and the life stage of pest plants present. Over more than 15 years, substantial progress has been achieved in reducing the impact of pest plants, with many areas advancing steadily through the FRF phases. Continuous data collection, combined with the team's extensive field knowledge, has built a deep understanding of the ecological dynamics within the catchments.

Title Nelson City Council Waterworks Reserves Pest Plant Control
Funding The project is funded by the Nelson City Council (NCC), which contracts Kaitiaki o Ngahere Ltd to undertake pest plant control operations in the Waterworks Reserves.
Study Area Description The managed area encompasses the Maitai and Roding catchments, located to the south and east of Nelson city. Together, they cover approximately 14,500 hectares (excluding roads, lakes, riverbeds and pine plantations). The area actively managed under the FRF has evolved over time but has consistently remained around 8730 ha in recent years.
Design Description The core of the design is the Forest Restoration Framework (FRF), which categorises management units or pest plant populations into distinct phases, typically progressing from Initial Control (mature plants present), Follow-up Control (addressing regrowth and seedlings after initial control), and Seedbank Control (focused on remaining seedlings) to Forest Protection (surveillance for new incursions). Each phase involves different frequencies and intensities of control. The first phases typically require annual visits to prevent seedlings from reaching maturity. In Forest Protection phases, visit frequency varies based on reinvasion risk. FP1 involves annual checks in high-risk or hotspot areas, while FP8 calls for visits every eight years in remote, low-risk forested areas. Additionally, some low-frequency or high-impact species are subject to separate, targeted controls regardless of the area's overall phase. The approach uses a spatial polygon format for targeted work and performance monitoring. These polygons, commonly referred to as Management Units (MUs), delineate specific areas or pest plant populations. Each polygon is assigned a FRF phase according to their pest plant status. This spatial approach enables targeted operations and efficient resource allocation. A crucial part of the design is the systematic collection of data. Tracklogs and point data are collected daily by field staff using GPS-enabled mobile platforms. This data builds a spatial database used for efficient, targeted control and informed decision-making. During control visits, field teams aim to systematically cover the designated MU. This is achieved either by following pre-designed GPS gridlines or by spacing themselves at intervals that ensure adequate visual coverage, depending on the target species and the level of infestation. Any areas not fully covered during one visit are prioritized the following one. In surveillance phases, the focus shifts to detecting and managing new incursions, particularly in high-risk areas such as lightwells, waterways, track edges.
