| Regional ecosystem | 3.1.4 |
|---|---|
| Vegetation Management Act class | Of concern |
| Wetlands | Intertidal |
| Biodiversity status | Of concern |
| Subregion | 9, 2, 4, 6, (7), (3), (5), (8) |
| Estimated extent1 | Pre-clearing 3000 ha; Remnant 2021 3000 ha |
| Short description | Excoecaria agallocha +/- Aegiceras corniculatum low open forest |
| Structure code | Low Open Forest |
| Description | Low open forest to low closed forest of Excoecaria agallocha (milky mangrove) +/- Aegiceras corniculatum (black mangrove) +/- Thespesia populnea (Pacific rosewood). A. corniculatum can be dominant when present. E. agallocha and Avicennia marina (grey mangrove) can sometimes be emergent. Similar species often occur in a very sparse sub canopy and/or shrub layer. The ground layer is often bare tidal mud with scattered seedlings. Occurs in upstream to intermediate estuarine areas in the mainly high intertidal zones throughout the bioregion. Intertidal. (BVG1M: 35a). |

| Protected areas | Rinyirru (Lakefield) NP (CYPAL), Endeavour River NP, Cape Melville NP (CYPAL), Lama Lama NP (CYPAL) |
| Special values | 3.1.4: 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: Non-flammable vegetation. Mangroves do not require fire. |
| Comments | 3.1.4: Common in Princess Charlotte Bay area. Also occurs as scattered communities in coastal areas including the Torres Strait. |
