Structure

Dry eucalypt forest and woodland to 20 m tall with a prominent sclerophyll shrub stratum and relatively sparse sclerophyll graminoid groundcover.

Trees

Eucalyptus acaciiformis (wattle-leaved peppermint), E. caliginosa (broad-leaved stringybark), E. cameronii (diehard stringybark), E. campanulata (New England blackbutt), E. codonocarpa (bell-fruited mallee), E. dalrympleana (mountain gum), E. oreades (Blue Mountain ash), E. radiata subsp. sejuncta (narrow-leaved peppermint).

Shrubs

Acacia buxifolia subsp. buxifolia (box-leaved wattle), Allocasuarina littoralis (black sheoak), Banksia integrifolia subsp. monticola, Bossiaea neo-anglica, Brachyloma daphnoides (daphne heath), Cryptandra scortechinii, Grevillea scortechinii subsp. sarmentosa, Hibbertia riparia, Kunzea bracteolata, Leptospermum brevipes, L. nova-anglica, Leucopogon lanceolatus, L. neo-anglicus, Lomatia silaifolia (crinkle bush), Mirbelia confertiflora, Monotoca scoparia (prickly broom-heath), Persoonia cornifolia, P. rufa, Petrophile canescens (conesticks), Platysace ericoides, Rhytidosporum procumbens.

Forbs

Dianella caerulea (blue flax lily), Gonocarpus tetragynus, Goodenia hederacea subsp. hederacea, Patersonia glabrata (leafy purple-flag), Poranthera microphylla, Pteridium esculentum (bracken), Entolasia stricta (wiry panic), Lepidosperma laterale.

Habitat

Leucogranite outcrops on high mountain plateaux (800 to 1400 m elevation) on the northern escarpment of New South Wales. The terrain is variable and commonly studded with tors and boulders. Soils are low-nutrient sandy loams. Temperatures are cool, but become high in summer and the average rainfall exceeds 850 mm of per year.

Distribution

Scattered and restricted occurrences on the northern escarpment from Werrikimbe to Bald Rock, extending into Queensland around Girraween, and with related vegetation as far north as the Blackdown Tableland, west of Rockhampton. Examples occur in Bald Rock, Boonoo Boonoo, Gibraltar Range, Warra and Cathedral Rock national parks, Bolivia Hill Nature Reserve, and further south around Mt Boss.

Notes

Scattered occurrences in a matrix of Northern Tableland Wet Sclerophyll and New England Dry Sclerophyll Forests, both of which occupy more fertile soils. Transitional communities also occur with Northern Tableland Dry Sclerophyll Forests, which replaces this class with declining rainfall. Species composition also varies between the disjunct patches of leucogranite. Poor soils and rocky terrain of the Northern Escarpment Dry Sclerophyll Forests has generally made these forests unattractive for agriculture and timber getting.
