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).

Protected areas Capricornia Cays NP, Capricornia Cays NP (S), South Cumberland Islands NP
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 13.1 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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
