Description

Predominantly a sclerophyllous heath or scrub community although, depending on site topography and hydrology, some remnants contain small patches of woodland, low forest or limited wetter areas. Common species include Banksia aemula, B. ericifolia, B. serrata, Eriostemon australasius, Lepidosperma laterale, Leptospermum laevigatum, Monotoca elliptica and Xanthorrhoea resinifera.

Distribution

Once occupied around 5,300 hectares of land between North Head and Botany Bay in Sydney’s eastern suburbs. Surviving stands totalling approximately 146 hectares have been recorded from the local government areas of Botany, Randwick, Waverley, and Manly.

Habitat and ecology

  • Occurs on disjunct patches of nutrient poor aeolian (wind blown) dune sand.
  • The community possesses soil seed bank and has been observed to regenerate naturally on cleared sand where the soil profile remains intact.
  • Floristic composition and structural diversity is influenced by the size and disturbance history of the remnant.
  • Field observations indicate that after a prolonged period (>15 years) without fire or similar disturbance, the floristic composition and vegetation structure becomes simplified with a few species dominating the standing vegetation.
