Mabi Forest, also known as Complex Notophyll Vine Forest (or Type 5b), once covered the Atherton Tablelands area north and west of Malanda, occurring only on fertile basalt (red) soils in areas where rainfall is between 1300 and 1600mm. This forest type is now located solely within the Atherton Shire. It was originally classified in the 1960's by ecologists Len Webb and Geoff Tracey, based on its physical (structural) characteristics and species composition, using the Tolga Scrub as the basis for this description.
These structural characteristics include:
Widespread clearing of Mabi Forest has resulted in 3 plant species, the Pink Silky Oak, Atherton Sauropus and Atherton Turkey Bush being listed as 'vulnerable to extinction'. Four plants are listed as 'rare', the pink leaf Haplostichanthus, Coorangooloo Quandong, Red Penda and Gray's Cryptolepis.
