| Regional ecosystem | 3.2.25 |
|---|---|
| Vegetation Management Act class | Least concern |
| Wetlands | Not a Wetland |
| Biodiversity status | Of concern |
| Extent in reserves | This regional ecosystem is now mapped as 3.2.24c. |
| Short description | Sparse herbland of mixed herbaceous species on foredunes and beach ridges |
| Structure code | Sparse Herbland |
| Description | [RE not in use]²: This regional ecosystem is now mapped as 3.2.24c. A variety of forbs and graminoids occur, but only form a very sparse ground layer (20-50cm tall). Perotis rara (comet grass) and Bulbostylis barbata (watergrass) frequently have the highest cover, with Sarga plumosum (plume sorghum) dominating less frequently. Very sparse emergent shrubs (0.5-1.5m tall) and low trees (3-6m tall) may occur. Grevillea parallela (silver oak) is the most frequent tree and shrub. Associated with foredunes and low beach ridges along the coast. Not a Wetland. (BVG1M: 28d). |

| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Do not burn deliberately. 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. Unlikely to burn owing to sparsity of vegetation. Burning of this ecosystem may lead to dune instability. |
| Comments | 3.2.25: Coastal dunes acros the Peninsula, predominantly on the west coast and from Cooktown to Bathurst Bay. The naturalised species Chloris inflata* and Dactyloctenium aegyptium* can sometimes be dominant in the ground layer. |
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2 Superseded: Revision of the regional ecosystem classification removed this regional ecosystem code from use.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.
