Progress towards protection
An ecological assessment of the gorge in 2019 found at least 16 threatened and at-risk native plant species, including Canterbury pink broom and rōhutu/myrtle — both nationally critical — along with others that are regionally uncommon.
Controlling the large, shade-tolerant weed trees will help stop them from outcompeting the native species.
Project lead Billy Bartrum is thrilled with the progress so far.
“12,000 cherries and sycamore controlled is a tremendous effort. This work couldn’t have been achieved without everyone’s contribution to this project. I would like to extend a huge thank you to the landowners and agencies involved.”
Selwyn District Council project lead Andy Spanton agreed.
“2022 represented the start of this important programme and as such, will give the project team essential information that will be used to help guide the project over the next few years.
“We are in a good place now to plan for operational activities in 2023 and 2024. By that time, we should have a clear idea of the further resource required to complete the project.”
Next steps
It’s likely that a key focus for the next control season will be on the cotoneaster that dominates a large area of land in a site referred to as ‘Zig Zag’, adjacent to the Rakaia Gorge Walkway.
Landowner David Harper is also working on a control operation for this site, involving the stands of pines within this area, and wetland enhancement works on his property.
He said he’s proud to be involved in this project and is grateful to everyone involved.
“The Rakaia Gorge holds a special place in our hearts. We feel very excited that this is just the beginning of looking after this very important place. This will be something that future generations will carry forward.”
