| Short description | Casuarina equisetifolia woodland to open forest on foredunes on mainland and islands |
| Structure code | Woodland |
| Description | Casuarina equisetifolia woodland to open forest, sometimes with an understory of vine thicket species. Occurs on foredunes on mainland and islands. Not a Wetland. (BVG1M: 28a). Vegetation communities in this regional ecosystem include: 3.2.6a: Casuarina equisetifolia (beach sheoak) woodland to open forest. A very sparse shrub layer can occur and include Colubrina asiatica, Hibiscus tiliaceus and Sterculia quadrifida. The mixed but generally sparse ground layer can include Ipomoea indica, Spinifex longifolius and Thuarea involuta. Occurs on foredunes. Not a Wetland. (BVG1M: 28a). 3.2.6b: Casuarina equisetifolia open forest (18-25m) with a dense sub-canopy of vine thicket species including Aglaia elaeagnoidea, Cyclophyllum spp., Drypetes deplanchei, Diospyros maritima, Planchonella obovata (yellow boxwood), Premna serratifolia and Millettia pinnata. A sparse shrub layer often contains canopy species often with Eugenia reinwardtiana (Cedar Bay cherry) common. A sparse to dense groundlayer usually contains seedlings of canopy species. Occurs on coral cay islands. Not a Wetland. (BVG1M: 28a). |

| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: No fire management required. Protection relies on broad-scale management of surrounding country with numerous small fires throughout the year so that wildfires will be very limited in extent. ISSUES: Fire sensitive vegetation community. |
| Comments | 3.2.6: Widely distributed type. Also occurs in other coastal bioregions. Widely distributed type. Also occurs in other coastal bioregions. 3.2.6b: Masig and Kodel Islands. On Masig Island this community is under threat of fragmentation through clearing for expanding sewerage infrastructure requirements. |
