| Description | [RE not in use]²: This regional ecosystem is now mapped as 3.2.24c. Premna serratifolia (coastal Premna) dominates the variable canopy, which ranges in height from 1 to 4.5 metres and from sparse to dense cover. Colubrina asiatica, Mimusops elengi (tanjong), Guilandina bonduc, Eugenia reinwardtiana and Exocarpos latifolius may be present as subdominant shrubs. Scattered emergent trees up to 8m are sometimes present. The ground layer is sparse to mid-dense, and dominated by a variety of herbs including Ipomoea pes-caprae, Lepturus repens and Sporobolus virginicus. Restricted to the coral cays and sand cays. Not a Wetland. (BVG1M: 3a). |

| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: No fire management required. ISSUES: Fire sensitive vegetation type. |
| Comments | 3.2.31: In a variant (vegetation unit 162A) the shrub layer is dominated by Dodonaea platyptera, with Premna serratifolia subdominant and Abrus precatorius abundant. In a second variant (vegetation unit 162B) Colubrina asiatica or Cordia subcordata are the dominant shrubs. The shrub and ground layer composition is similar to 3.2.31. Included in Littoral Rainforest and Coastal Vine Thickets ecological community protected under the Commonwealth's EPBC act (1999). Great Barrier Reef and Torres Strait islands. |
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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
