Southern Highlands Shale Forest and Woodland of the Sydney Basin Bioregion
The Southern Highlands Shale Forest and Woodland of the Sydney Basin Bioregion ecological community is endemic to New South Wales, occurring within the Sydney Basin Bioregion, as defined by version 7 of the Interim Biogeographic Regionalisation of Australia. The ecological community occurs on the Southern Highlands plateau and is typically associated with clay soils derived from Wianamatta Group shales.
 The ecological community has a tree canopy dominated by eucalypts and a typically herbaceous understorey. Three ‘forms’ of the ecological community are recognised: ‘typical’, ‘tall wet’ and ‘short dry’.
Characteristic canopy species of the Southern Highlands Shale Forest and Woodland that may be found in all forms of the ecological community include: Eucalyptus globoidea (white stringybark), E. piperita (Sydney peppermint) and E. radiata (narrow-leaved peppermint). In addition to the aforementioned species, the ecological community may be dominated by one or more of the following canopy species:
·      In the ‘typical’ form - by Eucalyptus macarthurii (Paddy’s River box). Eucalyptus pauciflora (snow gum) may also be present but not as a dominant species. Eucalyptus amplifolia (cabbage gum) and/or E. tereticornis (forest red gum) often occur. Eucalyptus ovata (swamp gum) is often present at poorly drained sites. In addition, a Penrose variant is dominated by E. blaxlandii (Blaxland’s stringybark); a Bundanoon variant often includes Angophora floribunda (rough barked apple); and a Braemar variant is often dominated by E. fibrosa (red ironbark) and E. punctata (grey gum), reflecting a stronger sandstone influence.
·      In the ‘tall wet’ form - by Eucalyptus cypellocarpa (mountain grey gum), E. elata (river peppermint), E. obliqua (stringybark), E. ovata (swamp gum), E. quadrangulata (white-topped box), E. smithii (gully peppermint, Blackbutt peppermint) and/or E. viminalis (manna gum, ribbon gum).
·      In the ‘short dry’ form - by Eucalyptus cinerea (Argyle apple, silver leaved stringybark), E. dives (broad leaved peppermint), E. mannifera (brittle gum), E. rubida (candlebark, ribbon gum). Eucalyptus pauciflora may also occur, and while not a dominant species, its frequency in this form reflects the increased exposure to frost and lower rainfall.
Where present, the shrub layer is typically sparse, although it may be dense. The ground layer is typically dense, dominated by grasses and herbs including: Poa sieberiana (fine leaved tussock grass), P. labillardierei (river tussock), Themeda triandra (kangaroo grass), Rystidosperma (syn. Joycea) pallida (red-anther wallaby grass) and Microlaena stipoides var. stipoides (weeping grass), Hypericum gramineum (small St John’s wort), Poranthera microphylla, Lobelia purpurascens (syn. Pratia purpurascens) (whiteroot) and Viola hederacea (native violet).
The ecological community supports a diverse range of fauna providing essential resources such as shelter and food including: Nyctophilus spp. (long-eared bats); Cercartetus nanus (eastern pygmy possum), Anthochaera phrygia (regent honeyeater); Petroica boodang (scarlet robin); and Heleioporus australiacus (giant burrowing frog).
