erve. This site was chosen to be included on the World Heritage list because:
“ "Criteria (ii) and (iv): Australia’s eucalypt vegetation is worthy of recognition as of outstanding universal value, because of its adaptability and evolution in post-Gondwana isolation. The site contains a wide and balanced representation of eucalypt habitats from wet and dry sclerophyll, mallee heathlands, as well as localised swamps, wetlands, and grassland. 90 eucalypti tax (13% of the global total) and representation of all four groups of eucalypts occur. There is also a high level of endemism with 114 endemic taxa found in the area as well as 120 nationally rare and threatened plant tax. The site hosts several evolutionary relic species (Wollemia, Microstrobos, Acrophyllum) which have persisted in highly restricted micro sites. Fauna
