Weed control (yellow flag iris) | Kaiapoi River
We are planning targeted weed control of yellow flag iris (Iris pseudacorus L.) on the lower Kaiapoi River berms starting Monday 8 November.
The planned dates of operation are:
- First control application operation: Monday 8 November to Thursday 11 November.
- Second application operation: Monday 13 to Friday 17 December.
This work is part of our Berm Transition Project which aims to increase the value, resilience, and function of the berms. It one of six projects in our Climate Resilience Programme of Flood Risk Management Projects.
NIWA recommends the best way to control yellow flag iris is with a strategic mixture of the aquatic herbicide metsulfuron-methyl (EPA approval code: HSR000242) and glyphosate. We will be operating under Environment Canterbury’s Resource Consent CRC981580 for glyphosate per consent conditions and the EPA approval for metsulfuron. Spraying will be hand-held using a knapsack, there will be no spraying over water.
We will be erecting precautionary signage to restrict public use of the water that states:
Within 100m of the application area: do not swim, do not gather food from the waterway (including fish); and do not take water for consumption.
The signs will be erected on the day of the operation, prior to commencement of spraying, and remain in place for five days after application.
Tree felling | Waimakariri River Regional Park.
We will be salvaging windthrown trees on the north bank of the Waimakariri River Regional Park, between Diversion Road and Downs Road.
Work will start mid-December and continue for around two months.
There will be some closures on Harrs Road and the surrounding park area. The orange shaded area on the map will be closed during the weekdays, this includes Dixons Bay.
There will be signs stating the closures, and physical fences will be established when tree processing and felling is within 50 meters of the road. We ask that park users please respect the signage and fences.
