MR WERP: Motupipi River Willow Eradication Project

The Motupipi River is a 4.5km spring-fed river that passes near to highways and roads, through dairy farms and residential properties on its way to the sea. The river is narrow and has an abundance of crack willows growing along the river which has spread into the river bed, choking the river and reducing its flow. This choking is contributing to the buildup of sediment, higher E Coli levels and more algal growth. The surrounding farmland is contributing to higher nitrate and E Coli levels and high nutrients and sediment and lack of shading is causing excessive algal growth which in turn is lowering oxygen levels and is adversely affecting native fish and macroinvertebrates.

NZLT Nelson/Marlborough Regional Coordinator Annette Litherland is supporting a five-year project named MR WERP (Motupipi River Weed Eradication and Restoration Project) funded by Tasman Environmental Trust, Tasman District Council and the Fonterra Grass Roots Fund. Annette’s role in the project is to work alongside interested landowners to plan willow removal and any fencing that is needed, and if requested, develop a planting plan for that land. Planting will be implemented under the guidance of the MR WERP steering committee, made up of local farmers, Project De-Vine representatives, and staff from each of the funding bodies.
