| Short description | Acacia shirleyi or A. catenulata open forest on coarse-grained sedimentary rocks. Crests and scarps |
| Structure code | Open Forest |
| Description | Acacia shirleyi and/or A. catenulata woodland to open forest. Other Acacia spp. such as A. sparsiflora and A. rhodoxylon may form part of the canopy and in places may predominate. Scattered Eucalyptus spp. emergents may occur, the most frequent being E. crebra, although Corymbia trachyphloia, E. decorticans and E. thozetiana may occur. Scattered tall shrubs may occur. A low shrubby layer is usually conspicuous. The ground layer is usually very sparse and composed of both grasses and forbs. Occurs on crests and ridge tops formed on consolidated, medium to coarse-grained sediments. Not a Wetland. (BVG1M: 24a). |

| Protected areas | Carnarvon NP, Chesterton Range NP, Expedition (Limited Depth) NP, Precipice NP, Isla Gorge NP, Snake Range NP, Humboldt NP, Nuga Nuga NP |
| Special values | 11.10.3: Habitat for threatened flora species including Acacia deuteroneura, A. wardellii and Bertya calycina. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: 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: Typically not enough ground vegetation to carry a fire. |
| Comments | 11.10.3: Subject to logging for specialised furniture products. |
