Riparian Planting Manawatu

Year 9 -10 rangatahi got down and dirty planting at the AFFCO-RYEBURN Farms.  Kindly sponsored by Oroua River Catchment Care Group, Affco Manawatu, Horizons RC, Manawatu District Council and Ngati Kauwhata Iwi, our students joined with scores of community to engage in riparian planting.

Students were provided with a good overview from the Oroua River Catchment Care Group and Affco river care group on activities undertaken over the past years.

Stuff NZ reports in their June 2017 article that 'stream planting is the biggest act farmers could do improve Waikato's water quality, DairyNZ water scientist Tom Stephens says: 'The plants alongside streams and other waterways provided shade which lowered the water temperature and created a more healthy environment for insects, Stephens told farmers at the DairyNZ Farmers' Forum at Lye Farm near Newstead'. 

Horizons Regional Council reports  in their Community Guide to Stream Restoration that the 'Manawatu Region is home to 17 different species of native freshwater fish and numerous freshwater invertebrates. Restoring areas by planting native trees along our streams and rivers will help to:

  •  Improve water quality
  •  Reduce stream bank erosion
  • Create habitat for aquatic life and birds
  • Improve the food source for aquatic life
  • Reduce water temperature fluctuations'

One of the aims of this event was enabling the community to plant endemic plants back in the area that are not invasive. Our youth learnt that for successful plant growth it is important they choose the right plants for the area. If an area is wet and boggy or close to the waters edge and could get flooded, then they needed to plant “wet feet types” (flax, sedges, toetoe).  All native trees and shrubs were to be planted further back from the stream where the ground is less saturated.
