  • Of the top ten tallest tree species in the world 4 are eucalyptsAnd the tallest flowering plant is Eucalyptus regans
  • They are distributed in fire-retardant habitats but ironically requiring of fire for regeneration. They regeneration mechanism and their mode of fire adaptation is therefore of great relevance to fire ecology
  • The relevance to social and political issues like forestry and fire management
