Description
The Upland Basalt Eucalypt Forests of the Sydney Basin Bioregion is typically tall open eucalypt forests found on basalt and basalt-like substrates in, or adjacent to, the Sydney Basin Bioregion. The ecological community usually occurs at elevations between 650 m and 1050 m above sea level (a.s.l.) (Keith & Benson, 1988, 1990; Fisher et al., 1995; Tozer et al., 2006), although outliers may occur at elevations as low as 350 m (e.g. closer to the coast) or as high as 1200 m a.s.l. (e.g. on higher plateaux). The ecological community occurs in areas of high rainfall, generally ranging from 1000 to 1800 mm/year (NSW Scientific Committee, 2004; Tozer et al., 2006). The structure of the ecological community varies from tall open forest to woodland depending on aspect, slope, soil conditions, soil depth, and previous disturbance (Fisher et al., 1995; NPWS & Sydney Catchment Authority, 2003; NSW Scientific Committee, 2004). Typically, the ecological community has a sparse to dense layer of shrubs and vines, and a diverse understorey of native grasses, forbs, twiners and ferns (Keith, 2004). With increasing distance from the coast (and a corresponding decrease in rainfall), the understorey tends to grade from relatively mesic (significant component of rainforest species), to relatively scleric (more drought and fire-tolerant shrubs and a more prominent grass layer) (Benson & Howell, 1994; Fisher et al., 1995). Rainforest elements are also present in the more inland remnants with sheltered aspects and topography, and along watercourses (Benson & Keith, 1990). The ecological community may also be affected by cold air drainage and ponding resulting in a more open, grassy forest. In order to meet the definition of the TEC sites must satisfy condition criteria stipulated in the Listing Advice and/or Conservation Advice. Typically condition is assessed by reference to patch size and vegetation structure thresholds or species composition metrics.

Recovery strategies
Priority actions are the specific, practical things that must be done to recover a threatened species, population or ecological
community. The Office of Environment and Heritage has identified
0 priority actions
to help recover the Upland Basalt Eucalypt Forests of the Sydney Basin Bioregion in New South Wales.
Activities to assist this species
- Nomination of the Woronora Plateau as an AOBV
- Liaise with NPWS and WaterNSW on the location of this TEC using the new SVTM and PCT-associations; making sure there is differentiation between the state listed RBTOF
