| Structure code | Low Closed Forest |
| Description | [RE not in use]²: This regional ecosystem is not mapped. Semi-deciduous mesophyll to notophyll vine forest commonly including Aleurites moluccanus (candlenut), Argyrodendron polyandrum (brown tulip oak), Alstonia scholaris (milky pine), Garuga floribunda var. floribunda, Bombax ceiba and Canarium australianum (scrub turpentine). There is a sparse to mid-dense sub-canopy tree layer and a very sparse shrub/low tree layer usually present. Occurs on granite slopes. Not a Wetland. (BVG1M: 2b). Vegetation communities in this regional ecosystem include: 3.12.1a: [RE not in use]²: This regional ecosystem is no longer mapped. The dense, uneven canopy (18-23m tall) is composed of a mixture of deciduous and evergreen trees. Aleurites moluccanus (candlenut), Argyrodendron polyandrum (brown tulip oak), Acacia polystachya, Alstonia scholaris (milky pine), Arytera divaricata and Cleistanthus peninsularis are frequent evergreen components of the canopy, occurring at high stem densities in some areas. Frequent deciduous canopy trees include Garuga floribunda var. floribunda, Bombax ceiba, Canarium australianum (scrub turpentine), Miliusa horsfieldii and Brachychiton grandiflorus. These trees may occur as emergents in places. The sparse to mid-dense sub-canopy tree layer (8-20m tall) is composed of a variety of species with Cryptocarya triplinervis var. riparia, Diospyros fasciculosa, Aidia racemosa, Argyrodendron polyandrum, Arytera divaricata, Barringtonia calyptrata, Berrya javanica and Bosistoa medicinalis occurring most frequently. The palm Ptychosperma macarthurii is sometimes present in the sub-canopy. A very sparse shrub/low tree layer (1-8m tall) is usually present with Tritaxis australiensis, Alectryon tomentosus, Buchanania arborescens (native mango), Eugenia reinwardtiana, Ficus opposita, Leea novoguineensis, Phaleria octandra, Arytera bifoliolata and Atalaya australiana occurring frequently. Climbers, particularly thin wiry vines such as Parsonsia velutina, are relatively frequent. Epiphytes are sparse. The ground layer is very sparse, and composed mainly of seedlings. Occurs on granite slopes. Not a Wetland. (BVG1M: 2b). 3.12.1b: [RE not in use]²: This vegetation community is not mapped. The dense, uneven canopy (18-23m tall) is composed of a mixture of deciduous and evergreen trees.

Frequent deciduous canopy trees include Garuga floribunda var. floribunda, Bombax ceiba, Canarium australianum (scrub turpentine), Miliusa horsfieldii and Brachychiton grandiflorus.

The sparse to mid-dense sub-canopy tree layer (8-20m tall) is composed of a variety of species with Cryptocarya triplinervis var. riparia, Diospyros fasciculosa, Aidia racemosa, Argyrodendron polyandrum (brown tulip oak), Arytera divaricata, Barringtonia calyptrata, Berrya javanica and Bosistoa medicinalis occurring most frequently. The palm Ptychosperma macarthurii is sometimes present in the sub-canopy. A very sparse shrub/low tree layer (1-8m tall) is usually present with Tritaxis australiensis, Alectryon tomentosus, Buchanania arborescens (native mango), Eugenia reinwardtiana, Ficus opposita (sandpaper fig), Leea novoguineensis, Phaleria octandra, Arytera bifoliolata and Atalaya australiana occurring frequently. Climbers, particularly thin wiry vines such as Parsonsia velutina, are relatively frequent. Epiphytes are sparse. The ground layer is very sparse, and composed mainly of seedlings. Occurs on metamorphic slopes. Not a Wetland. (BVG1M: 2b). |
| Special values | 3.12.1: The near threatened species Brachychiton grandiflorus occurs in this ecosystem. |
| Comments | 3.12.1: Western slopes of the McIlwraith Range. 3.12.1a: Western slopes of the McIlwraith Range. |
1 Estimated extent is from version 13 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.
