Results and research

The information gained from FORESTCHECK highlights the extraordinary diversity of life that thrives in the jarrah forest.

  • Compared with flowering plants and vertebrates, studies on the classification of invertebrates, fungi and lichens are limited, yet these three groups accounted for 84 per cent of the total biodiversity recorded by FORESTCHECK in the first 10 years.
  • An abundance of relatively unknown species of invertebrates, fungi and lichens have been documented, many of which were collected and recorded for the first time, and are yet to be named.
  • Timber harvesting in the jarrah forest does not appear to have had a major impact on the number of species present.
    • Analysis shows that harvested forest has a different composition of species to non-harvested forest.
    • The change in species composition is necessary for ecological processes to continue and is one reason why the jarrah forest is so diverse.
  • The importance of species successions will be the focus of future analysis.
  • Data from the first five years of monitoring have been published in Australian Forestry, and data from 10 years of monitoring are currently being analysed.
