Gondwana Link

Ecological communities

As you move from east to west along Gondwana Link the natural vegetation systems and the wildlife they support change dramatically. In the east, bordering the Nullarbour Plain, is the largest intact Meditteranean woodland in the world. Here an impressive variety of tall eucalypts interspersed with incredibly species rich sand heath thrive in areas which receive only 250-300mm rainfall per year. As you continue west the woodlands and sand heath give way to mallee and Kwongan heath. Further west, as the annual rainfall begins to increase taller eucalytps again appear. Different species and understory occur on different soil types and rainfall zones. Very roughly speaking, as your move from the Fitzgerald towards the west coast the dominant tree type changes from Flat topped yate woodlands to wandoo, jarrah-marri, karri, tingle then back to karri and jarrah-marri.

Rainfall (which varies from 200-1100mm per year across the link), soil type, topography, nutrient levels...  all sorts of physical factors determine what vegetation can grow in any one place.
