  • Eucalyptus dalrympleana and Eucalyptus pauciflora forming a dominant stratum, with a varied understorey that may be shrubby or grassy or both.
  • Favours hillsides and steeper slopes over metamorphic substrates, often with much broken rock at or near the surface, but some flatter areas have been heavily grazed.
  • Favours higher altitudes, rarely occuring below 800 metres elevation.

Newnes Plateau Narrow-leaved Peppermint - Silvertop Ash Layered Open Forest

Key identifying features

  • Taller forest or woodland of Eucalyptus radiata and Eucalyptus sieberi, often with Eucalyptus blaxlandii and Eucalyptus oreades, over a moderately dense and quite diverse shrub layer.
  • Eucalyptus fastigata is absent, Eucalyptus dives and Eucalyptus piperita are in low numbers.
  • Groundcover density is variable but usually quite diverse, with Joycea pallida and Poa sieberiana the dominant tussocks, and Goodenia, Lomandra, Patersonia and Pteridium esculentum often in good numbers.
  • On flatter / broader ridges, but will occur on upper slopes and  below pagoda outcrops.

Sandstone Platau and Ridge Scribbly Gum - Silvertop Ash Shrubby Woodland

Key identifying features

  • An open forest or woodland community of the Narrabeen ridges, with Eucalyptus sieberi (silvertop ash) and Eucalyptus sclerophylla dominating. The understorey is diverse and shrubby, although it varies in density from open to quite dense - probably as a result of disturbance history.
  • Eucalyptus piperita is usually absent from the unit, and Eucalyptus blaxlandii is very uncommon.
  • The soil is typically quite shallow, and loose rock may be present on the surface.

  • Relatively sparse groundcover, with forbs, graminoids and bracken fern predominating.
  • Favours shallow to somewhat deeper sandy loam or earthy sand soils, usually near ridgecrests and on more
    gentle slopes.
  • Usually does not have Eucalyptus sieberi  and Eucalyptus oreades
