East Wallabi Island - Flora

Flora

See also: Flora of the Houtman Abrolhos

As one of the few islands in the Houtman Abrolhos large enough to support dune systems, East Wallabi Island supports a relatively high diversity of plant life. Both the dunes and the pavement limestone support species-rich vegetation complexes dominated by chenopod shrubs, and these communities have been identified has having species conservation importance, because they are so diverse, yet so easily disturbed and so slow to recover.
