Regional ecosystem details for 3.2.26
Regional ecosystem | 3.2.26 |
---|---|
Vegetation Management Act class | Least concern |
Wetlands | Not a Wetland |
Biodiversity status | No concern at present |
Subregion | 4, 2, (6), (3), (9), (1) |
Estimated extent1 | Pre-clearing 14000 ha; Remnant 2021 14000 ha |
Short description | Sparse herbland and/or shrubland and bare sand areas predominantly on sand blows |
Structure code | Bare |
Description | Sparse herbland/shrubland which can include Acacia crassicarpa, Alyxia spicata, Leucopogon spp. and Sersalisia sericea in the shrub layer and a very sparse ground layer with Dapsilanthus spathaceus, Mitrasacme paludosa and Xyris complanata. An emergent layer with Acacia crassicarpa or Corymbia novoguinensis can occur. The majority of this regional ecosystem is devoid of vegetation and consists of actively moving wind-blown sand blows and sand cays that are inundated during very high tides. Areas naturally devoid of vascular plants, predominantly sand blows. Not a Wetland. (BVG1M: 28d). |
Supplementary description | Neldner and Clarkson (in prep), 198; Stanton, Fell & Gooding (2008), D14s. |
Protected areas | Wuthathi (Shelburne Bay) NP (CYPAL), Bromley (Ampulin) NP (CYPAL), Apudthama NP (CYPAL), Cape Melville NP (CYPAL), Wuthathi (Saunders Islands) NP (CYPAL), KULLA (McIlwraith Range) NP (CYPAL) |
Special values | 3.2.26: Potential habitat for NCA listed species: Dendrobium bigibbum, Dendrobium johannis. |
Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: No fire management required. ISSUES: Non-flammable vegetation. Low fuel loads and sparse vegetation limits fire spread. |
Comments | 3.2.26: In areas where the dunes are beginning to stabilise, a gegenvalle landscape develops where low shrubs occur on small raised areas with bare sand occurring between these areas. Mainly associated witht the extensive duenfields in Shelburne Bay and Cape Flattery but occurs elsewhere on coast and cays. |
