Land use
The catchment of the Bellinger River is slightly disturbed. Around 85% of the catchment remains forested, a lot of which is in the undulating areas of the upper catchment. Around 15% of land use has been changed, predominantly for cattle grazing, and these areas are concentrated along the floodplains of the river and its tributaries. Bellingen and Urunga are the major towns within the catchment; however they make up a small fraction of the land use within this large catchment.
