Grazing

Grazing is the biggest land use in the Great Barrier Reef catchment area occupying 31.1 million hectares of land (73% of the catchment). Grazing lands can be vulnerable to soil erosion and are estimated to contribute 60% of the total load of fine sediment exports to the Great Barrier Reef. […]
