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.
Researchers have discovered that the rugged gullies within the Greater Blue Mountains World Heritage Area are home to rainforest communities that have been previously hidden and misclassified in official maps. A study led by Western Sydney University ecologist Dr. Eli Bendall identified that more than 90% of the rainforest in the Hawkesbury region of New South Wales (NSW) is likely mislabeled as eucalypt forests.
Using high-resolution mapping and remote field surveys, the study found that the actual rainforest extent is three to four times greater than previously reported in the NSW State Vegetation Type Map. The newly described rainforest types, Hawkesbury Warm Sheltered Gully Rainforest and Hawkesbury Subtropical-Dry Bench Rainforest, support ancient Gondwanan plant lineages and regionally rare species.
These rainforests are fire-sensitive and do not respond well to fire, making urgent vegetation-map updates and enhanced protection measures crucial for their preservation.
