A new product using dag wool is to be launched in Nelson this week. Manufacturer Terra Lana is using dag wool to make a mat that can be used in landscaping. Business development specialist Brad Stuart said the DagMat, being launched at the Institute of Landscape Architects conference, can be used for soil retention around road edges, or around the base of trees and shrubs, to support ground-cover growth, weed suppression and to protect plants. Brad Stuart says Civil roads projects could use it for erosion control and to mitigate sediment runoff. The product would be made locally in Christchurch and could replace imported products made from hessian, coconut fibre or jute.
