These units are based on Silurian and Ordovician age sediments and consist of the Yalmy Scarp, the sedimentary terrain of the Rodger River Basin and the dissected sedimentary terrain north of the Deddick River including Mt. Tingaringy, peneplains of the NSW border area and east to Dellicknora. The Mt. Tingaringy Peneplain is regarded to have more in common with the steeper surrounding terrain than the lower elevation Low hill and Hill units. These Mountain units tend to have shallow stony profiles particularly on the crests, upper slopes and mid-slopes but many have greater soil development (deeper) elsewhere. The vegetation consists of Montane Sclerophyll Woodland, Snow Gum Woodland, Montane Forest (Snow gum) at higher elevations and Dry Sclerophyll Forest, Rainforest Woodland, Wet Sclerophyll Forest, some Riparian and Cool Temperate Rainforest. Geology: S; Silurian. Quartzitic sandstone, mudstone, shale. Ou; Ordovician. Black slate, phyllite, shale, sandstone. Siltstone, minor schist, hornfels, contact rock, breccia, scree quartz. Rainfall: 700-1200 mm per annum, generally 700-1000 mm per annum. Slope: 32 - greater than 100%, generally 32-56%. Dominant landform element: Slope. Minor landform element: Peneplain, drainage depression. |
