Threats to coastal dunes

Threats to coastal dunes in New Zealand include:

  • Residential development and urban encroachment into coastal areas
  • Colonisation of native dunes by exotic species such as boneseed, pampas grass and spread of garden weeds into dunes
  • Extensive planting of exotic species such as marram, lupins and pines
  • Grazing and disturbance by animal pests (such as rabbits) and stock
  • Use of vehicles (such as motorbikes and 4-wheel drive vehicles) and horses in dunes which detroy nesting seabird habitat and vegetation
  • Presence of dogs that disturb and kill nesting birds
