Manilkara kauki, Terminalia subacroptera, Canarium australianum, Eugenia reinwardtiana, Sarcostemma viminale subsp. brunonianus, Alyxia spicata, and Drypetes deplanchei. Emergents of Pandanus sp. to 8m are scattered throughout the complex. Similar to other communities within this grouping, the community has formed in response to extreme wind exposure and skeletal soils. This community is not florisitically typical of this proposed new RE, lacking Melaleuca spp. as a dominant component. It does however occupy a similar ecological niche to VC’s 14a, 14f and 14l and, due to its extremely limited areal extent, has been placed within this grouping in the absence of a more suitable one. 5.2.72 Regional Ecosystem 3.12.33b Photograph 157. Windswept shrubland community 14g on exposed granite footslopes of Dauan Island. Site DA041. Description: Granite boulders covered with blue-green algae. Occurs on Black Mountain and Cape Melville. Status: Of Concern Vegetation Communities: 19a, 11a Reference Sites: 4 Quaternary Vegetation Community 19a: The most extensive occurrence of RE3.12.33 is mapped on Dauan Island where it occupies extensive areas of hillslope, generally in a mid-slope position. Smaller areas are mapped on Hammond and Muralug Islands. The community is best described as an open granite boulder field with scattered vine forest shrubs, low trees and occasional vine thicket. Woody cover is typically less than 5% comprising Canarium australianum, Ficus microcarpa, Cochlospermum gillivraei and Tetrameles nudiflora. Sprawling mats and low towers of the vine Aristolochia acuminata are locally prominent and ground cover of Drynaria quercifolia, Asplenium sp. and Sarcostemma viminale subsp. brunonianus are occasionally present in sheltered pockets. This community represents a significant geographical departure from mainland Cape York Peninsula examples at Black Mountain and Cape Melville. Small areas of Pandanus woodland are also recognised within this RE and are discussed below. Vegetation Community 11a: Pandanus dominant woodland on granite headlands are scattered throughout a large number of the larger continental islands. In the majority of examples, these communities have been too small to represent individually and thus consumed within a broader vegetation complex. The communities on Dauan, represented as VC11a (on granite) are sufficiently developed to allow classification as an individual VC. The extremely limited spatial 3d Environmental – Torres Strait Regional Ecosystem Mapping Project – August 2008 150
extent of this community greatly restricts the ability to classify it appropriately within the RE framework as as such, it has been place within the broader RE3.12.33b grouping in recognition of its similarity in landform and edaphic condition. 5.2.73 Regional Ecosystem 3.12.34c Photograph 158.

Preliminary Description: Rock pavements associated with hillslopes and footslopes of the Torres Strait Islands.* Status: Of Concern Vegetation Communities: 18a, 18b (co), 18c (co), 18d, 14w (co), RR, RG Reference Sites: 13 Quaternary This RE classification provides for representation of a range of rock pavements and rock pavement shrublands that have a considerable extent on a number of continental islands. Whilst RE3.12.34 presents a suitable classification in a structural sense, the type description is geographically confined to the Melville Range and Black Mountain cannot be applied to the 3d Environmental – Torres Strait Regional Ecosystem Mapping Project – August 2008 151
