| Description | Bare rock pavements with small areas of sparse herblands, grasslands or shrublands where there is soil accumulation. A wide variety of species may occur and include Acacia umbellata, Hoya spp., Rhynchosia spp., Cymbopogon spp., Triodia spp., Ectrosia spp., Fimbristylis spp., Cochlospermum gillivraei, Canarium australianum (mango bark), Psydrax spp., Terminalia spp, and Carissa ovata (currant bush). Occurs on bare rock pavements on hills where a little soil accumulates and in the crevices between the rocks or in depressions where a moderate depth of soil has accumulated. Not a Wetland. (BVG1M: 29b). Vegetation communities in this regional ecosystem include: 3.12.34a: [RE not in use]²: This vegetation community now mapped as 3.12.34. This unit consists of bare rock pavements with small areas of sparse herblands composed of ephemeral herbs where a little soil accumulates. In the crevices between the rocks or in depressions where a moderate depth of soil has accumulated, a tall shrubland may develop. This is usually dominated by deciduous species. Occurs on bare rock pavements on hills where a little soil accumulates and in the crevices between the rocks or in depressions where a moderate depth of soil has accumulated. Not a Wetland. (BVG1M: 29b). 3.12.34b: [RE not in use]²: This vegetation community now mapped as 3.10.19c. This unit consists of bare rock pavements with small areas of sparse herblands composed of ephemeral herbs where a little soil accumulates. In the crevices between the rocks or in depressions where a moderate depth of soil has accumulated, a tall shrubland may develop. This is usually dominated by deciduous species. Occurs on bare rock pavements on sandstone hills where a little soil accumulates. Not a Wetland. (BVG1M: 29b). 3.12.34c: [RE not in use]²: This vegetation community now mapped as 3.12.34. This unit consists of bare rock pavements with small areas of sparse herblands composed of ephemeral herbs where a little soil accumulates. In the crevices between the rocks or in depressions where a moderate depth of soil has accumulated, a tall shrubland usually dominated by deciduous species may develop. These may include Cochlospermum gillivraei (kapok), Canarium australianum (scrub turpentine), Terminalia spp., Psydrax spp., and Carissa ovata. Rock pavements associated with granite offshore islands. Not a Wetland. (BVG1M: 29b). |

| Special values | 3.12.34: Potential habitat for NCA listed species: Acacia armitii, Torenia polygonoides. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: No fire management required. ISSUES: Rock pavement with scattered vegetation; unlikely to burn. |
| Comments | 3.12.34: Occurs as a complex of rock pavements (rather than boulder piles of 3.12.33) with shrubland that can include Acacia umbellata, Canarium australianum, Psudrax spp., Terminalia spp. and Carrisa ovata growing in areas where soil accumulates. McIlwraith Range, Iron Range and Altanmoui Range. Torres Strait Islands. 3.12.34a: Iron Range and Altanmoui Range. Also upper reaches of the Archer River. 3.12.34b: Clack Island, Flinders Group. 3.12.34c: Concentrated around islands in the Torres Strait. |
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.
