Vegetation Structure

  • Boundary between open woodland and moorland
  • Open E. coccifera / E. subcrenulata woodland, 10-15m in height, <40% cover
  • Understorey of shrubs to 1.5m composed of Bauera rubioides and Richea scoparia.
  • Moorlands consist of emergent shrubs of Leptospermum rupestre, Epacris serpyllifolia, Boronia citriodora.
  • Groundcover >95% consisting of Gleichenia alpina and Astelia alpina.

Vegetation Processes

  • Factors causing abrupt boundary include; 
  • frost and cold air drainage
  • Fire frequency
  • Drainage and edaphic factors.
