Why are we doing this?

Flood protection

The Ashley River/Rakahuri is a key feature of the North Canterbury landscape and one that poses a major flood risk to the local community living on its floodplain. For this project, costing about $1 million, we are planning to remove exotic vegetation (mainly willow and brush weeds) which is currently choking a 21 kilometre section of the river between Ashley Gorge and the Okuku River confluence, and in the Okuku River. Left unchecked this vegetation is a flood and erosion risk, occupying the channel and forcing flood waters towards farmland. Weed growth can also contribute to the loss of aquatic habitats and nesting areas for native birds.

Protection and restoration of our braided rivers

Braided Rivers are a precious and iconic part of the Canterbury environment. We are prioritising the protection and restoration of their unique values as part of our Braided River Revival/Whakahaumanu Ngā Awa ā Pākihi work. As a result of the introduction and invasion of weeds, predators, and human activities, braided rivers and their bird species, plants, native fish and insects are under threat. Through this project in the Ashley River/Rakahuri, and others across the region, we are working on the restoration of our rivers normal braided character, which will in turn will enhance a range of natural biodiversity values, including natural braided river habitats.
