Estimated percentage landcover for vegetation class

Structure

Tall eucalypt forest 30-40m, with an open subcanopy of non-rainforest trees up to 15 m tall, scattered understorey shrubs and a dense groundcover of grasses and herbs.

Trees

The canopy is dominated by a combination of Eucalyptus brunnea, E. cameronii ( diehard stringybark), E. campanulata (New England blackbutt), E. obliqua ( messmate), E. saligna (Sydney blue gum), with E. dorrigoensis (Dorrigo white gum) and E. nobilis (ribbon gum) localised in open gullies. An open subcanopy may be formed by Acacia irrorata (green wattle), Allocasuarina littoralis (black sheoak), A. torulosa (forest oak) and Banksia integrifolia subsp. monticola.

Shrubs

Goodia lotifolia (golden-tip), Hibbertia aspera (rough guinea flower), Indigofera australis (hill indigo), Leucopogon lanceolatus, Persoonia linearis narrow-leaved geebung), P. media, Polyscias sambucifolius, Rubus parvifolius (native raspberry). Less commonly present, Lomatia fraseri (silky lomatia) and Trochocarpa laurina (tree heath) have scattered occurrence.

Scramblers

Hibbertia scandens (climbing guinea flower).

Forbs

Dianella caerulea (blue flax lily), Dichondra repens (kidney weed), Drymophila moorei (orange berry), Poranthera microphylla, Pratia purpurascens white root), Viola betonicifolia (mountain violet), V. hederacea (ivy-leaved violet), Pteridium esculentum (bracken), Deyeuxia parviseta var. parviseta, Entolasia stricta (wiry panic), Lomandra longifolia (spiny-headed mat-rush), Microlaena stipoides var. stipoides (weeping grass), Poa labillardieri, Poa sieberiana var. sieberiana (snowgrass).

Habitat

Elevated plateaux and upper escarpment slopes above 800 m. These areas receive approximately 950-1100 mm rainfall annually, less than the adjacent escarpment edge and slopes. Soils are relatively fertile loams derived mainly from fine-grained metasediments.

Distribution

Escarpments and associated plateaux north from Barrington district, extending a short way into south-east Queensland, with outliers extending west along the Liverpool Range. Examples occur on the Carrai Plateau, and the western parts of New England, Guy Fawkes River and Washpool national parks.

Notes

Relatively species-rich assemblages, primarily due to their diverse ground flora. Grades into Northern Escarpment Wet Sclerophyll Forests with increasing moisture status and Northern Tableland Grassy Woodlands with decreasing moisture status. Relatively unaffected by land clearing, the main conservation challenges are management of the impacts of fires and livestock grazing on understorey structure and diversity.
