How rugged gullies protect hidden rainforests in the Greater Blue Mountains
Researchers have uncovered rainforest communities previously hidden within the rugged gullies of the Greater Blue Mountains World Heritage Area that are protecting vegetation not known to grow anywhere else.
Research published in the journal Vegetation Classification and Survey has revealed that hidden rainforests within the rugged gullies of the Greater Blue Mountains are significantly larger and more diverse than previously thought. Led by Western Sydney University ecologist Dr. Eli Bendall, the study employed high-resolution mapping and remote field surveys in the Hawkesbury region of New South Wales.
The findings indicate that over 90% of rainforests in the area may be misclassified in official maps as eucalypt forests. These gullies house complex, fire-sensitive rainforests with vegetation types not previously recognized in NSW, and serve as a refuge for ancient Gondwanan plant lineages and rare species. The study highlights the urgent need for updated vegetation maps and stricter fire protection measures to safeguard these unique ecosystems.
