Activities that support water for the environment

The planning and delivery of water for the environment involves a range of supporting activities including scientific monitoring, evaluation and water trading.

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:

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

Monitoring and evaluation

All watering targets and events include monitoring to assess the effectiveness of environmental flows. 

OEH undertakes the following monitoring activities across all major valleys:

  1. Inundation mapping which maps the timing and extent of flows
  2. Wetland vegetation condition and extent mapping to assess the response of vegetation to managed flows
  3. Animal surveys to assess the response of selected animal species to watering events

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

Water trading

OEH trades a small proportion of available water each year to partially recover water use fees associated with water licenses. Trading will continue to occur in future years to manage the portfolio for the maximum environmental benefit.
