Supporting activities

Science and research

The NSW Office of Environment and Heritage is committed to a scientific approach to the management of water for the environment.  The following scientific activities are undertaken in collaboration with partners:

  • flora and fauna surveys in wetlands, rivers and floodplains
  • development of decision support tools to manage environmental water
  • water-bird and fish habitat studies
  • researching ecological wetland functions and process
  • modelling of environmental water

Monitoring and evaluation

All environmental watering targets and events include monitoring to assess the effectiveness of environmental water.  Some valleys such as the Gwydir, Macquarie Marshes and the Lowbidgee wetlands have a more intensive monitoring investment. 

OEH undertakes the following monitoring activities across all major valleys:

  1. Inundation mapping which maps the timing and extent of environmental water
  2. Wetland vegetation condition and extent mapping to assess the response of vegetation to environmental water
  3. Fauna surveys to assess the response of selected fauna species to environmental water

Monitoring outcomes are shown in each of the valley pages. 

Monitoring information and research is summarised and integrated into an adaptive decision making approach to environmental water.

Water trading

OEH trades a small proportion of available water each year to partially recover water use fees associated with water licenses. In 2013/14, OEH traded 22,650 megalitres of water across the Gwydir, Macquarie, Lachlan, Murrumbidgee and NSW southern Murray Darling Basin valleys.  Trading will continue to occur in future years to manage the portfolio for the maximum environmental benefit.
