• Forest Type #46; Sydney Blue Gum
  On the highest fertility sites at around 950m ASL to the south of the Lodge, on soils derived from a basalt capping a tall, moist eucalypt forest of almost pure Sydney Blue Gum with occasional Brush Box occurs. The trees are mostly regrowth from sapling to spar size with a few mature trees. There are also a few rainforest trees such as Crabapple, Soft Corkwood and Hoop Pine and a well-developed mesophytic understorey of rainforest shrubs, small trees and vines. There may have been a small semi-natural grassland plain similar to Chapmans Plain and other Dorrigo grassland plains on top of the wide knoll associated with the basalt capping. Severe cold and periodic burning may have perpetuated this grassland plain in the past. The Sydney Blue Gum represents a cold hardy pioneer for the regenerating rainforest. In the absence of fire and other disturbance over a long period (>200 years) this forest may develop into a Cool Subtropical Rainforest of Sub-alliance #12 with mature Sydney Blue Gum and Brush Box emergents.

• Forest Type #47; Tallowwood-Sydney Blue Gum
  In sheltered and moderately fertile (may be due to basalt enrichment) sites that have been free of fire for many years, a tall (up to 55m), moist eucalypt forest (Wet Sclerophyll Forest) dominated by Tallowwood and Sydney Blue Gum occurs. Associated trees include Brush Box, Turpentine, Silvertop Stringybark and New England Blackbutt. As above there is a well-developed small tree and shrub layer of rainforest species. In the absence of fire and other disturbance over a long period (>200 years) this forest may develop into a Cool Subtropical Rainforest of Sub-alliance #12 or possibly an Intermediate Cool Subtropical / Warm Temperate Rainforest of Sub-alliance #33 with mature Tallowwood, Sydney Blue Gum and Brush Box emergents.
  

• Forest Type #163; New England Blackbutt-Tallowwood
  In somewhat less fertile but still relatively moist sites with infrequent fire a tall (up to 55m) wet sclerophyll forest occurs but with a change in dominant species. Sydney Blue Gum, although present, becomes less frequent to be replaced by New England Blackbutt as the main associate of Tallowwood. Other associates are Messmate and Silvertop Stringybarks, Brown Barrel and Manna Gum. This forest type has a more or less mesophytic (rainforest) understorey depending on fire frequency. In the absence of fire and other disturbance over a long period these forests may develop into a Warm Temperate Rainforest of Sub-alliance #36 with Tallowwood and New England Blackbutt emergents.
  

• Forest Type #160; New England Blackbutt-Diehard Stringybark
  On sites of low to moderate fertility, but moist aspect with infrequent fire, Tallowwood is replaced by Diehard Stringybark in a tall Wet Sclerophyll Forest. The understorey is more or less mesophytic depending on fire frequency. In the absence of fire and other disturbance over a long period these forests may develop into a Warm Temperate Rainforest of Sub-alliance #36 with New England Blackbutt and Diehard Stringybark emergents.

• Forest Type #163; New England Blackbutt-Tallowwood
  On drier sites with a more northerly or westerly aspects fire becomes more frequent. On sites of moderate to high fertility the same forest type as above may occur but as a medium (less than 25m) to tall (up to 35m) Dry Sclerophyll Forest. The understorey may consist of xerophytic (dry/heath) shrubs or may be grassy depending on the frequency of fire.
  
• Forest Type #160; New England Blackbutt-Diehard Stringybark
  On similarly dry aspects but on sites of only low to moderate fertility Tallowwood becomes less frequent to be replaced by Diehard Stringybark as the main associate of New England Blackbutt. Other associates may be Brown Gum, Messmate Stringybark and Manna Gum. This open forest may be either medium (less than 25m) in height or tall (up to 35m). As above, the understorey may consist of xerophytic (dry/heath) shrubs or may be grassy depending on the frequency of fire.

• Forest Type #152; Messmate-Gum
  On moist sites with low fire frequency at altitudes over 1100m a tall (up to 30m), moist eucalypt forest occurs which is dominated by Messmate in association with New England Blackbutt, Brown Barrel, Giant White Gum and Snow Gum at the highest altitudes. The understorey is more or less mesophytic depending on fire frequency and includes White Banksia. In the absence of fire and other disturbance over long periods this forest may develop into a Warm Temperate Rainforest of Sub-alliance #36 or an Intermediate Cool/Warm Temperate Rainforest of Sub-alliance #40.

• Forest Type #152; Messmate-Gum
  On drier aspects sites at similar altitude the above Forest Type occurs as a medium (less than 25m), dry eucalypt forest again dominated by Messmate but in association with Diehard and Youman’s Stringybark, Narow-leaved and New England Peppermints, Brown Barrel and Mountain Gum. The understorey may consist of xerophytic shrubs or grass depending on the frequency of fire.

• Coachwood Alliance, Suballiance #33
  At altitudes of 850m to 1000m ASL in moderately sheltered sites sub-optimal for the development of pure Cool Subtropical Rainforest an Intermediate Cool Subtropical / Warm Temperate Rainforest occurs. The dominant canopy trees are Yellow Carabeen, Black Booyong and Sassafras with the occasional Mountain Walnut, Crabapple, Rosewood and Purple Cherry. The sub-canopy consists of Coachwood, Prickly Ash and Brown Beech.

• Coachwood Alliance, Suballiance #36
  At altitudes of 950m to 1200m ASL in somewhat more exposed sites there is a Warm Temperate Rainforest dominated by Coachwood, Sassafras, Rough Possumwood and with only occasional Yellow Carabeen, Prickly Ash, Soft Corkwood and Crabapple. Here the cold intolerant Coachwood can only survive to higher altitudes where sheltered by the taller Sassafras.

• Sassafras Alliance, Suballiance #40
  At even higher altitudes of 1200m to 1400m on argyllite in relatively sheltered gully heads of Mt. Hyland there occurs an Intermediate Warm Temperate / Cool Temperate Rainforest. The canopy is up to 30 metres high and dominated by Sassafras and Mountain Walnut with the occasional Rough Possumwood and Crabapple. In the sub-canopy Prickly Ash and Mountain Laurel are common with the occasional Mountain Olive-berry, Mountain Marara and Mountain Tree Heath. This is a very interesting rainforest type as a number of the tree species present, as well as some species of fern, are commonly associated with Antarctic Beech elsewhere. Floyd considers that Antarctic Beech probably once occurred here but has died out in past arid periods.

• Sassafras Alliance, Suballiance #40
  On the more exposed ridge spurs and slopes the above rainforest type occurs in a depauperate form type with a low, dense canopy consisting of the wind tolerant small-leaved tree species Sassafras, Mountain Walnut and Mountain Olive-berry. Also common is Mountain Tree Heath and there are few emergent White Banksias, some of which have attained huge proportions.

• Sassafras Alliance, Suballiance #46
  Warm Temperate Closed Scrub occurs on the steep, very exposed and rocky sites with skeletal soils in the headwaters of Obeloe and Blicks Creeks at altitudes of 1000 to 1400m. Dominating these "scrubs" are Yellow Tea-tree, Veined Mock-olive and Mountain Tree Heath. Other common shrubs are White Banksia, Blackwood and New England Tea-tree. Due to the fact that these "rocky islands" are surrounded by rainforest, and have only a sparse ground layer due to the skeletal soil, they have enjoyed a considerable period of freedom from wildfire. These sites may have been fire free for several hundred years as indicated by the relatively large sized specimens (more than 10 metres) of the normally small tree and shrub species.
