| Short description | Pemphis acidula low closed forest on coral atolls, shingle cays and sand cays |
| Structure code | Low Closed Forest |
| Description | Pemphis acidula low closed forest. Other mangrove species may be present as low trees. Rhizophora stylosa and Avicennia marina (grey mangrove) are often present in the canopy as well. A sparse mixed shrub layer (1-4m tall) is sometimes present. The sparse to mid-dense ground layer usually contains Sesuvium portulacastrum with Ipomoea pes-caprae and Suaeda australis also common. A closed scrub of P. acidula with emergent mangrove species can also occur. Restricted to the coral atolls, shingle cays and sand cays. Intertidal. (BVG1M: 35a). |

| Special values | 3.2.30: Provides estuarine wetland habitat. |
| 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 | 3.2.30: It can occur in three situations: (1) on seaward shores of sand cays, (2) most frequently on the inner margins of conglomerate platforms on the windward sides of low woodland islands, and (3) at the junction of the sand cays and mangroves. Great Barrier Reef and Torres Strait islands. |
