This group of units consists of a range of elevated (uplands), undulating, rolling and steep granodiorite/granite units around Bonang extending west to the Snowy River and at Campbells Knob. Some of these units lie in rainshadow areas and are the driest part of the region. Much of this area within these units has been cleared for grazing. The soil types of these units range from shallow to moderately deep coarse brown and red gradational profiles to deep yellow, brown and occasionally red duplex profiles on lower and mid slopes. Drainage lines may have multi-layered (uniform or duplex) profiles. Vegetation consists of Dry Sclerophyll Forest, Rain Shadow Woodland with minor Wet Sclerophyll Forest and Riparian Forest. The Rain Shadow Woodland is west of Tubbut, centred around the Deddick River valley. There are also a number of minor outcrops such as that along the Bonang Highway/Coulsen Track and Yalmy Road near the Pinnak Road junction. These units range from undulating to steep terrain. Geology: Dgl; Devonian Granodiorite/granite. Rainfall: Less than 700 mm and 200 mm – 1000 mm per annum. Slope: Variable; 3-56%. Dominant landform element: Slope. Minor landform element: Drainage depression, swamp. |
