Grass buffer strips in the fenced riparian zone can be very effective at filtering contaminants in paddock run-off. However, planted riparian margins can also have other benefits such as:
- Cooling the water to provide better habitat for aquatic species;
- Providing corridors linking habitat for native species;
- Providing shade and shelter for stock;
- Making stock management easier; and
- Improving the attractiveness of your property.
For help planning what to plant where, contact one of our land management advisors or check out our 'Clean Streams - guide to riparian management' and 'Northland natives guide' publications in our resource library and the DairyNZ riparian planting guide at www.dairynz.co.nz/environment/waterways
In the absence of stock grazing there is the potential for weeds to get established within the fenced riparian margin, especially if there's very little ground cover. A regular weed control programme is recommended, which council staff can provide advice on.
Check out our weed control information in the Pest Control Hub.
Pest animal control
Undisturbed riparian areas can also become havens for pest animals, such as stoats, weasels, rats, wild cats and hedgehogs. These can be trapped or poisoned. Joining or establishing a Landcare group in your area can provide useful support for managing pests.
Find our pest animal information in the Pest Control Hub or contact the council's biosecurity team for more advice on pest control.

Video series: Planting for the land
This short video series follows a planting project on Good Eggs farm, to improve the land and reduce sediment going into local streams.
It’s one of many similar events happening around the area to improve water quality in the Mangere catchment, which ultimately flows into the Kaipara Harbour.
And it’s a great example of local communities working together to protect and restore Northland’s environment.
Episode 1 - Good Eggs
Check out the story of a planting project on Good Eggs farm, to improve the land and reduce sediment going into local streams.
