Reducing Erosion on Auckland's Coasts

Auckland Council is carrying out studies to aim at reducing erosion on Auckland’s coasts.


“The coasts of New Zealand were once clothed in native vegetation”,says an environmental spokesperson at Auckland Council .


“The plant communities would have ranged from highly salt-tolerant species, typical of estuaries, dunes and rocky cliffs, to hardy ferns, shrubs and trees, typical of coastal broad-leaf forest.” 


“Coastal forests, clifftops, banks and dunes are some of New Zealand’s most threatened ecosystems.


Coastal forests have been reduced by over 90 per cent from their original extent, and less than 10 per cent of New Zealand’s sand dunes remain unmodified.


Good vegetation cover on land bordering the sea can help coastal ecosystems by:

  • providing habitats for native birds and animals
  • preventing erosion of soil and sand by wind and water
  • shading out invasive weeds
  • preserving the natural character of our coastal environment.

Coastal planting requires an ongoing commitment to weed management until the plants have successfully establish. You need to remove weeds from around plants for 2-3 years, or until the native plants are high enough to over-top the weeds and crowd them out.”
