Comments 8.12.17a: Distinguished from other microphyll rainforest regional ecosystems on land zone 12 by a combination of occurring on the main Clarke range (subregion 3) at moderate to high altitudes, and occurring in the cloudy moist to very wet rainfall zone (above 2000mm and often cloudy/misty). The vegetation community 8.12.17b is similar but tends to be more notophyll dominated. Occurs only in subregion 3, in the mountains at high altitude. It is found in Eungella National Park on Clarke Range, on Blue Mountain (30km south-west of Sarina) and in an area about 10km south of Sarina. 8.12.17b: Distinguished from other microphyll rainforest regional ecosystems on land zone 12 by a combination of occurring on the main Clarke range (subregion 3) or in the Shoalwater area (subregion 4) at moderate altitudes, and occurring in the cloudy moist to cloudy wet rainfall zone (above 2000mm and often cloudy/misty). The vegetation community 8.12.17a is similar but tends to be more microphyll dominated. Occurs in subregion 3 in small isolated patches on Mount Hector and Mount Quandong south of the Proserpine Dam. Also occurring more extensively on Coast Range to the north-west of Corio Bay, within subregion 4. 8.12.17c: Distinguished from other microphyll rainforest regional ecosystems on land zone 12 by a combination of occurring on the Conway Range only (subregion 1) at low to moderate altitudes (but along ridgelines and on plateaus) and occurring in the moist to wet rainfall zone (about 2000 to 2400mm). Occurs in subregion 1, entirely within Conway National Park, along the ranges from Mount Merkara (north of Shute Harbour), south to the tip of Cape Conway.
