Vegetation Structure

  • Rainforest canopy species (Nothofagus sp. and Atherosperma) approximately 25-30m and 95% coverage, emergent eucalypts upto 60m.
  • Understorey generally composed of rainforest species
  • Groundcover dominated by ferns and bryophytes.

Vegetation Processes

  • Mixed forest- a reality or a seral successional stage, a disclimax.
  • Light limitation on understorey vegetation restricts growth to rainforest species.
  • Absence of a fire event in the next 50-100 years will result in die-off of emergent eucalypts and no regeneration of eucalypt seedlings therefore a pure rainforest will result.
  • A fire event in the near future may shift vegetation towards a wet sclerophyll vegetation type.
