Investigating the drivers of endemism and biodiversity of eastern Australia’s forest on volcanically derived soils formed during Australia’s separation from Gondwana
Volcanic hotspot tracks formed in the Early Eocene in Queensland and continued into New South Wales during the Oligocene through to present-day Victoria. These elevated volcanic formations may have acted as a refugium for many species during Australia’s many climatic phases and glacial cycles. Accordingly, these potential refugia may be biodiversity hotspots that harbour rare and endangered species with a high degree of endemism. To understand what risks future climate change may pose on their distribution, an understanding of factors that influenced their existence is first required.
