Let's stop erosion!

Retaining fertile soil on the land is in the interests of all New Zealand. Without tree protection hills fall apart in severe rain storms. Poplars and willows planted for erosion reduction stabilise our pastoral hill country, increase water storage, reduce sediment transfer, improve water quality, benefit stock and enhance the farm environment.

There are poplars and willows to suit each region and location.

Working in close association with regional authorities and industry partners, NZPWRT develops adaptable planting materials (poplar & willow), provides technical support and promotional information to assist landowners to reduce soil erosion, lower sediment transfer off farm, and improve water quality.
