New data on water and soil health in NSW forests


Researchers have delivered new research on the health of waterway and soils in NSW forests under the NSW Forest Monitoring and Improvement program.

For example, researchers at the University of Melbourne found annual water flows have decreased in forested catchments over the last 35 years in NSW Regional Forest Agreement areas, with most significant decreases in south coast forests. One third of coastal forest catchments had 10 to 20 percent flow decreases relative to the long-term average. These reductions are likely induced by climatic factors.

In other research, scientists at the University of Sydney and the NSW Department of Planning, Industry and Environment have found soil carbon has slightly declined over the last decade in NSW Regional Forest Agreement areas. However, significant fluctuations have occurred in this period. Climate change is predicted to contribute to a decline in soil carbon over most of the study area, particularly the southern alps.
