Jarrah Print 2
Jarrah forest exists only on the western edge of the Darling Plateau in the South West Division of Western Australia.
When looking for the causes of the great biological diversity in the jarrah forest, it is necessary' to go back to the formation of the soil on the landforms it grows out of, under the influence of a changing climate.
Its soils have been weathered from the rocks beneath the plateau they created 4500 million years ago to the earth's foundation. They are called the Yilgarn Block.
The Yilgarn Block has remained in the place where it was born when rocks first hardened on earth. It has never been upheaved by underlying earth movement nor the soil renewed in any way.
