<strong>Vegetation</strong> Community 14l: The inner isl<strong>and</strong>s of Zuna, Horn <strong>and</strong> Hammond host VC14l, which<br />

similar to VC14a, occupies steep coastal headl<strong>and</strong>s directly exposed to prevailing south-easterly<br />

trade winds. The community is manifest as a low shrubl<strong>and</strong> to shrubl<strong>and</strong>, typically 1m to 1.5m<br />

tall with an upper shrub layer composed of, in order of decreasing dominance, Melaleuca<br />

viridiflora, Acacia brassii, Lithomyrtus retusa, Welchiodendron longivalve, Jacksonia thesioides,<br />

Corymbia nesophila, Asteromyrtus symphyocarpa, Melaleuca stenostachya, Alyxia spicata,<br />

Acacia simsii, Halfordia kendack, <strong>and</strong> Psydrax reticulata. This community is structurally similar<br />

to VC14a although a more diverse upper stratum warrants recognition as an individual<br />

community.<br />

<strong>Vegetation</strong> Community 14g: The shrubl<strong>and</strong> complex 14g is most prominent on exposed granite<br />

boulder footslopes on Dauan Isl<strong>and</strong> although a minor area has also been differentiated on Iama<br />

Isl<strong>and</strong>. The upper stratum of this community forms a dense shrubby thicket that is generally<br />

impenetrable, with a typical height of not greater than 1.5m. Species representative of the<br />

dominant upper stratum (S1 layer) include Buchanania arborescens, Manilkara kauki, Alyxia<br />

spicata <strong>and</strong> Pouteria sericea. On Iama, the unit includes coastal vine thicket species such as<br />
