| Short description | Argusia argentea low woodland, restricted to coral, shingle and sand cays |
| Structure code | Low Woodland |
| Description | Argusia argentea low woodland to open scrub (1-5 m, 10-60% FPC). The seaward margins usually comprised of small shrub/trees and the landward margins had the taller stands. The understorey is very sparse or absent. Common ground cover species are: *Lepidium englerianum, Lepturus repens, Stenotaphrum micranthum, Sporobolus virginicus and Boerhavia albiflora var. albiflora (0.6 m, 2-10%). Abutilon albescens, Achyranthes aspera, *Portulaca oleracea and Tribulus cistoides occur along the landward margins. Litter cover ranged from 15-60%. Restricted to coral, shingle and sand cays. Not a Wetland. (BVG1M: 28a). Vegetation communities in this regional ecosystem include: 12.2.19a: Argusia argentea, Scaevola taccada open scrub. Restricted to coral, shingle and sand cays. Not a Wetland. (BVG1M: 28a). 12.2.19b: Argusia argentea open scrub to closed scrub with emergent Casuarina equisetifolia subsp. incana. Restricted to coral, shingle and sand cays. Not a Wetland. (BVG1M: 28a). 12.2.19c: Suriana maritima open to closed scrub. Restricted to coral, shingle and sand cays. Not a Wetland. (BVG1M: 28a). 12.2.19d: Scaevola taccada open to closed scrub. Restricted to coral, shingle and sand cays. Not a Wetland. (BVG1M: 28a). 12.2.19e: [RE not in use]²: This vegetation community is now classified as 12.2.19c. Suriana maritima open to closed scrub. Restricted to coral, shingle and sand cays. Not a Wetland. (BVG1M: 28a). 12.2.19f: Ximenia americana closed scrub. Restricted to coral, shingle and sand cays. Not a Wetland. (BVG1M: 28a). |

| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. ISSUES: Do not burn deliberately. These islands are nesting habitat for seabirds; fire at inappropriate times could disrupt breeding cycles. |
| Comments | 12.2.19a: Masthead Island In Capricornia Cays National Park. 12.2.19c: Wreck Island and Heron Island in the Capricornia Cays National Park. 12.2.19f: Restricted to coral, shingle and sand cays. Currently only known from Tryon Island in the Capricornia Cays National Park. |
1 Estimated extent is from version 13 pre-clearing and 2021 remnant regional ecosystem mapping. Figures are rounded for simplicity. For more precise estimates, including breakdowns by tenure and other themes see remnant vegetation in Queensland.
2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use. It is included in the regional ecosystem description database because the RE code may appear in older versions of RE mapping and the Vegetation Management regulation.
