He said while the use of non-native species like poplar and willow for erosion control surprises some people, the trees are specifically chosen because their fast growth rates means they can begin working as intended much more quickly.
"These trees play a key role in stabilising land and cutting erosion and sedimentation in Northland, the latter - while a natural substance - still being one of our biggest contaminants of our streams and waterways," he said.
The best time to plant the trees in Northland is typically from June to mid-August. The bulk of this year's pole supply is from the council's own poplar and willow nursery near Whangarei as well as selected local partners.
The council set up its six hectare nursery in Flyger Rd, Mata, several years ago after becoming frustrated with the limited supply of suitable poles in Northland and being unable to find anyone able to grow large numbers on its behalf.
Interested landowners can contact the Land Management Team on 0800 002 004 to allow time to arrange a farm visit to undertake a required planting plan.
