In Swannanoa, a significant native planting initiative is transforming the landscape of Andrew and Peter Gilchrist’s 430-hectare farm, part of a broader ecological restoration project led by Waimakariri Irrigation Limited (WIL). This project, the first of its kind in the area, aims to enhance and protect the region’s freshwater systems and biodiversity.
The initiative is a key component of WIL’s biodiversity project, which spans a 44,000-hectare command area. In 2018, a biodiversity survey identified 297 sites of ecological interest, with a focus on safeguarding existing significant areas and fostering a unified approach to biodiversity restoration across neighbouring lands.
A critical element of this project is the 2.5km section of Burgess Stream on the Gilchrist property, featuring several springheads crucial for the health of the entire stream system. Dan Cameron, WIL’s biodiversity project lead, emphasises the importance of starting restoration efforts at the source to maximise impact and accelerate benefits downstream.
The Burgess Stream, which traverses 13km of WIL shareholder land before reaching lifestyle block properties, presents an opportunity for extensive environmental restoration. Cameron envisions a collaborative effort involving both shareholders and lifestyle block owners to enhance the entire stream ecosystem.
Andrew Gilchrist highlights the rewarding experience of involving his staff and local school children in the planting project. This collaboration not only fostered community engagement but also allowed for more efficient use of funds, with a $10,000 grant from Environment Canterbury dedicated entirely to plant purchases. Staff involvement in site preparation and maintenance further enhanced the project’s impact.
The selection of native plants was meticulously planned, focusing on species native to the area and those providing ecosystem services.
Plants like Carex secta, known for its denitrifying properties, and flax, a valuable food source when in bloom, were chosen for their environmental benefits. The long-term goal is to create a network of resource-rich habitats to attract native birds, increase invertebrate and insect populations, and provide shade for the stream.
Gilchrist’s experience has been overwhelmingly positive, noting significant benefits since the project’s inception three years ago. He encourages other farmers to engage in environmental initiatives, with plans to continue planting along the entire stream, demonstrating a commitment to ecological stewardship and community involvement in environmental conservation.
