The ultimate goal is to support natural regeneration and promote the recovery and diversity of indigenous forest ecosystems. This work is being carried out under a three-year weed control project commissioned by Nelson City Council in September 2023. The Brook Conservation Reserve is a significant natural area managed by Nelson City Council, surrounding the 690-hectare fully fenced Brook Waimārama Sanctuary (BWS) on the eastern edge of Nelson City. While the sanctuary is a predator-free ecological restoration site with strict biosecurity protocols – combining community-led conservation and ecological research – the Brook Conservation Reserve serves as a public recreation area. Management Unit D (MU D), within the reserve, acts as a crucial ecological buffer to the BWS, helping protect native flora and fauna in the adjacent Management Unit A, located next to the fenced sanctuary. Recognised in the 2020 Brook Valley Eastern Hills Ecological Restoration Plan as having "particularly high ecological value", MU D also forms part of Significant Natural Area (SNA) 186. It provides riparian cover for Cummins and Glen Creeks and contributes to the scenic backdrop of Nelson City. Despite being dominated by mature indigenous forest, MU D remains vulnerable to weed incursions from surrounding areas. To address this, Nelson City Council commissioned Kaitiaki o te Ngahere Ltd. in September 2023 to undertake a three-year weed control project, guided by the Forest Restoration Framework – an outcome-focused model for long-term ecological restoration. This framework classifies management areas into distinct phases based on operational progress and the age class of pest plants present. It offers a clear and systematic approach for both site-led and weed-led projects, with a strong emphasis on accountability and transparency. Data collection has been a core component of the program. Consistent data gathered through surveillance and control missions is building a detailed spatial database that underpins strategic planning, targeted operations, and transparent reporting for Nelson City Council. Beyond supporting operational efficiency and accountability, the data contributes to a deeper understanding of local ecological dynamics and enables monitoring of progress through the Forest Restoration Framework’s phases. Beyond its operational use, we seek to make this dataset available to a wider audience to support further research, ecological studies, and conservation initiatives. This work was made possible through the support of Nelson City Council, whose ongoing funding and collaboration have been instrumental in the management and monitoring of invasive plant species in The Brook Conservation Reserve. The dataset will be updated at the end of each financial year, once all control visits for that year have been completed. annually Isaline Jadin Kaitiaki o te Ngahere GIS Administrator

phillip.cochrane@ncc.govt.nz https://www.nelson.govt.nz/ Isaline Jadin author Brad Myer reviewer Phillip Cochrane reviewer The weed and wilding pine management project in the Management Unit D (MU D) of the Brook Conservation Reserve (BCR) was initiated in September 2023 as a three-year program. It forms part of a broader, multi-year ecological restoration initiative for the BCR and the wider Brook Valley Eastern Hills. The project emphasizes four main restoration strategies: pest plant control, ungulate hunting, pest animal control, and restoration planting. These strategies are designed to be implemented across the wider restoration area in a cohesive and connected approach. The overall restoration area covers 577 hectares and includes Tantragee, Atmore, and Eureka Park Landscape Reserves, as well as parts of the Brook Conservation Reserve. To support effective implementation, the area has been divided into 13 management units (A–M) based on factors such as proximity to the Brook Waimārama Sanctuary (BWS), vegetation types, and site-specific management needs. MU D has been identified as a high-priority unit for targeted pest plant and ungulate control because of its high ecological value and its role as an important buffer protecting indigenous flora and fauna in the adjacent Management Unit A, which borders the BWS. The primary objective of management in MU D is to reduce invasive pest plant populations – particularly vine weeds and wilding pines – to enhance indigenous forest diversity and support natural regeneration. These efforts also help protect the native flora and fauna in the adjacent fenced Brook Waimārama Sanctuary (BWS), by strengthening the ecological buffer provided by MU D. The programme is guided by the Forest Restoration Framework (FRF), a systematic, outcome-focused model developed by Kaitiaki o te Ngahere for both 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 of target species, enabling strategic and adaptive intervention. In its first year, the project focused on the initial control of mature vine weeds and mapping of reproductive wilding pines across MU D. The second year prioritised the completion of initial control in key hotspots – particularly gullies and lower slopes – as well as pine control across the entire unit. The third year will focus on follow-up control of both mature and immature vines and pines, and targeted seedbank control on the upper slopes. Substantial progress has already been achieved over the first two years, significantly reducing pest plant impacts and advancing ecological restoration in MU D. The Forest Restoration Framework’s structured approach ensures that efforts build upon each other, moving the area towards reduced pest plant density and diversity, and improving the resilience of this ecologically valuable landscape against future incursions. The project is funded by the Nelson City Council (NCC), which contracts Kaitiaki o Ngahere Ltd to undertake pest plant control operations in the Management Unit D (MU D) of the Brook Conservation Reserve. The managed area encompasses Management Unit D (MU D) of the Brook Conservation Reserve, located on the eastern edge of Nelson City. Covering 88.59 hectares, this management unit consists of mature indigenous forest—primarily beech and podocarp species—as well as regenerating native vegetation. It lies to the west of Fringed Hill and includes Bullock Spur, along with tributaries like Glen Creek and Cummins Creek, within an altitudinal range of approximately 300-675 metres asl. 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 eventually Forest Protection (surveillance for new incursions). Each phase involves different frequencies and intensities of control. The weed and wilding pine management project in MU D focuses on the first three phases. The approach uses a spatial polygon format for targeted work and performance monitoring. These polygons 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 polygons. 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. 2025-08-19T02:50:12.539+00:00 dataset Myer B, Jadin I, Cochrane P (2025).
