This bioregional assessment helps us understand how coal seam gas and coal mining development could affect water resources and water-dependent assets in the Gloucester subregion. It identifies where potential impacts could occur, as well as the areas that are unlikely to be affected.

At a glance

Additional coal resource development is predicted to cause minor hydrological change in the Gloucester subregion. No impacts on ecological assets are predicted in the south, given the limited additional coal resource development. In the north, potential impacts on ecological assets are expected to be minor and localised because predicted hydrological changes are small.

About the subregion

The Gloucester subregion is in New South Wales, north of the Hunter Valley. It is part of the Northern Sydney Basin bioregion. The largest towns in the subregion are Gloucester and Stroud. The main rivers are the north flowing Avon River and the south flowing Mammy Johnsons River. Most of the subregion is cleared of native vegetation and used for agriculture. Very little of the subregion lies within conservation reserves, but there are nationally and internationally significant wetlands and areas of ecological significance such as the Barrington Tops World Heritage area nearby.
