Geological History and Biodiversity
This region has a complex geological history. “The acid volcanics are 250-300 million years old and the Dorrigo Plateau west of Coffs Harbour was formed by the Ebor Volcano, active until about 18 million years ago.”**
The area is home to some of the most outstanding examples of biodiversity of the Great Eastern Ranges, with plant and animal lineages and communities that have remained relatively unchanged from their ancestors in the fossil record.
Located in the western uplands of the North Coast Bioregion it is one of the most geologically and biologically diverse in NSW according to the NSW National Parks and Wildlife Service and falls within the Northern Rivers Regional Biodiversity Management Plan.
This vast catchment area contains some of Australia's richest diversity of plants and animals that depend on a wide range of habitats, including rainforests, woodlands, wetlands, herb, heaths and grasslands. This is the main habitat for many threatened species of plant and animal.
In addition to nourishing the environment, the mountain headwaters supply most of our population on the eastern side of the watershed with reliable rainfall for clean water.
Mining exploration leases operated by Scorpio Resources Pty Ltd, a wholly owned subsidiary of Anchor Resources Ltd, include many of these fragile landscapes and adjoin the Gondwana World Heritage area of Mt Hyland Nature Reserve. “World heritage sites have universal value that transcends the value they hold for a particular nation”. This land is far too precious to plunder.
We acknowledge the traditional custodians of the Coffs Coast and hinterland area, the Gumbaynggirr Nation that stretches from the Nambucca River in the South to around the Clarence River in the North and the Great Dividing Range in the West. For more information click this link to a publication compiled by the Coffs Harbour City Library by Liz Thomas (Special Collections Librarian) in January, 2013. Further information on this heritage should be sought from the Coffs Harbour Aboriginal Lands Council or a recognised Elder within the Community.
