Moonah (Melaleuca lanceolata)
This tree, common on Rottnest and Garden islands, is known by many as Rottnest tea-tree.  It is able to grow closer to the ocean than almost any other tree, withstanding the limy soils and very salty winds.  It produces a dense mass of foliage, shielding the individual leaves from the deposition of salt.  In stands, the tree canopies combine in a single, almost unbroken layer.

Moonah is, however, killed by fire, and too frequent fires on the mainland coast have reduced its occurrence there.
