Freshwater Ecosystems

New Zealand has significant freshwater resources but water quality is under threat from the intensification of farming leading to excess nutrients entering the watershed and degradation caused by invasive weeds and pests. The Environmental Research Institute is undertaking a 10-year research project funded by  the Ministry of Science and Innovation (MSI) to investigate measures to mitigate these problems and improve water quality.

Areas of research expertise include:

  • Biodiversity
  • Harmful algal bloom dynamics and ecology
  • Microbiology
  • Lake restoration
  • Riverine ecology
  • Pest fish control and eradication
  • Nutrient modelling
  • Hydrology
  • Wetlands
  • Catchments
  • Environmental and resource economics
  • Environmental and resource Law
  • Remote sensing and GIS
