Community 2b at Site DA01 (Dauan<br />
Isl<strong>and</strong>).<br />
<strong>Vegetation</strong> Community 2f: Small areas of low deciduous vine thicket, typically with canopy<br />
heights ranging from 3m to 6m, are found on the steep exposed rocky headl<strong>and</strong>s of Horn <strong>and</strong><br />
Adolphus Isl<strong>and</strong>. The communities form a patchwork with sclerophyll shrubl<strong>and</strong> communities,<br />
<strong>and</strong> are attenuated attenuated upslope along gully lines where some shelter from the elements is<br />
afforded. The dominant canopy is occupied by a range of species which include, in order of<br />
decreasing dominance; Buchanania arborescens, Millettia pinnata, Sterculia sp. (Annan River),<br />
Terminalia subacroptera, Cochlospermum gilivraei <strong>and</strong> Pouteria sericea. Sub-canopy <strong>and</strong><br />
ground covers are poorly developed on account of the low stature <strong>and</strong> rocky substrate.<br />
Additional site survey would benefit the characterisation of this community.<br />

<strong>Vegetation</strong> Community 2n: <strong>Vegetation</strong> Community 2n is the dominant structural variation on<br />
Iama Isl<strong>and</strong> where it occupies wind-exposed footslopes on granite. The community is typically<br />
lower than VC2b <strong>and</strong> has a much more even <strong>and</strong> wind sheared canopy structure. The community<br />
was sampled at Sites YA014, YA017, YA019, YA20, YA23 <strong>and</strong> YA25 where typical canopy<br />
species included in order of decreasing dominance Canarium australianum, Antiaris toxicaria<br />
var. macrophylla, Gyrocarpus americanus, Terminalia subacroptera, Manilkara kauki, Acacia<br />
auriculiformis, Diospyros reticulata, Sterculia sp. (Annan River) <strong>and</strong> Premna dallachyana.<br />
