Manna Gum

Did You Know?

  • The foliage (high in protein) is the favoured food of the koala
  • Provides valuable hollows for hollow-nesting birds and mammals
  • Endangered species (Leadbeater’s Possum, Helmeted Honeyeater, Forty Spotted Pardalotes, Yellow-bellied and Sugar gliders) rely on it for food; they scratch or bite the bark to release the sugary gum or ‘Manna’
