B 3.44 Mountain, Sedimentary, Type 9
MsSm9
Soils: Dominant: Gn3.11, Gn3.71, Gn4.11. Red, brown friable gradational profile of organic loam A horizon and a silty clay loam B horizon moderately to strongly structured, very stony and shallow on exposed faces, deeper with less stone in sheltered sites.
Minor: Hardsetting, shallow uniform, gradational profiles, stony on upper slopes and crest (Gn3.91). Duplex profiles on lower slopes especially where drier (aspect, site drainage); strongly structured B horizons and massive or weakly structured lower A horizons (Dy3).
Native vegetation: The vegetation is predominantly Montane Sclerophyll Woodland; Candlebark, Snow Gum, Broad-leaved Peppermint, Silver Wattle, Gorse Bitter-pea and Prickly Bush-pea (Pultenaea juniperina). There is also some Dry Sclerophyll Forest, Montane Forest and Snow Gum Woodland which includes Alpine Ash (E. delegatensis).
Stone/rock outcrop: Stone; moderate; high on crest and upper slopes.
Pans: Nil or not observed.
Land use: The majority of the units are forested with most of the Mt. Delegate unit under freehold title. About one-third of this unit is a scenic reserve. There is a communications tower on top of Mt. Delegate.
Observed land deterioration: Some sheet erosion.
Susceptibility to land deterioration: Sheet and rill erosion (low to high); Gully erosion (low to moderately high); Compaction (moderately low to high); Inundation/Waterlogging (very low to moderate); Mass movement (moderately low to high).
Sites with laboratory data: Nil.

| These units include a unique landscape feature; the monadnock (residual hill) at Mt. Delegate. This unit is based on sedimentary terrain with some metamorphism. It dominates the landscape and forms a radial drainage pattern. This unit is generally steep, with less steep lower slopes which grade into the surrounding sedimentary/colluvial unit. There is also a river scarp (Queensborough River). Due to the rapid rise in elevation and a range of aspects the soil type varies from shallow stony lithosols to deep red friable gradational profiles in sheltered mid- to lower slopes. This rapid change in elevation also has a marked effect on the vegetation type and its distribution. The main native vegetation type is Montane Sclerophyll Woodland with some Dry Sclerophyll Forest, Montane Forest and Snow Gum Woodland (Mt. Delegate). Geology: Ou;. Ordovician sediments. Black slate, phyllite, shale, sandstone. Siltstone, minor schist, hornfels, contact rock, breccia, scree, quartzite. Rainfall: 700 – 1200 mm per annum, generally 700-1000 mm per annum. Slope: 32-56%. Dominant landform element: Slope. Minor landform element: Drainage depression. |  |
