Water Quality

Forests impact on water quality and yield. Healthy forests distribute water runoff and improve water quality.  In Tasmania, the Forest Practices Code gives considerable attention to the maintenance of water quality and stream flow.

Measures include:

  • limiting the areas harvested to not more than five per cent in any town water supply in any one year.
  • dispersing coupes and limiting their size to 100 ha.
  • keeping undisturbed streamside reserves as boundaries to harvesting coupes.
  • stopping operations during prescribed wet weather conditions.

Research by the Co-operative Research Centre for Catchment Hydrology at Monash University, Australia's leading research centre on water catchments, reveals it is difficult to detect changes in the yield of a water catchment if less than 20 per cent is disturbed in any one year.
