The Jarrah woodland is characterized by sandy soils with impressive granite outcroppings inserted in the woodland. There are grass trees and species of Banksia (the tree with funny looking flowers), and some beautiful wildflowers, including orchids.
When it rains, water collects in depressions found on the outcropping, which creates conditions suitable for unique ecosystems on a smaller scale. I think these were called "namas" (spelling?) by the Aborigines, and were used as sources of fresh water. They are characterized by lichens, mosses, and other specialized plants. Pretty cool, eh?
