Name Type Description Soils
Bombo Erosional Low rolling hills with benched slopes and sea cliffs with extensive rock platforms on Bumbo Latite. Relief 40 to 100 m. Slope gradients 15 to 25% with isolated steep slopes to 40%. Extensively cleared with dairying, grazing, hobby farms, recreation areas and quarrying of latite the main landuses. Shallow (>50 cm) Structured Loams occur on crests, moderately deep (50 to 100 cm) Krasnozems occur on upper slopes and benches. Brown Podsolic Soils occur on mid and lower slopes.
Wattamolla Road Depositional Long gently to moderately inclined sideslopes and undulating to rolling hills with broad benches on Budgong Sandstone. Relief >200 m. Slope gradients 5 to 15% with isolated steep slope >40%. Extensively cleared with only scattered stands of remnant forest present. Moderately deep (50 to 100 cm) Red Podzolic Soils occur on upper slopes and benches with Yellow Podzolic Soils on mid and lower slopes.
Shellharbour Erosional Low rolling hills with long sideslopes and broad drainage plains on Budgong Sandstone. Relief 30 to 50 m with slope gradients Deep (
Kiama Erosional Low rolling hills with broad crests and long convex slopes and steep coastal headlands on Blow Hole Latite. Extensive scattered rock outcrops present on upper slopes. Drainage plains >100 m wide. Relief 40 to 60 m with slope gradients >20%. Extensively cleared with cattle grazing and urban development the main landuses. Deep (
Cambewarra Erosional Steep to very steep hills with broad colluvial benches on latite. Relief 100 to 300 m. Slope gradients generally >30% with steep hillslopes (>50%) containing a talus of latite boulders and scattered rock outcrops present. Drainage lines are closely spaced and deeply incised. Partially cleared of vegetation with cattle grazing, hobby farms and conservation the main landuses. Deep (>200 cm) Red Solonetzic Soils and Krasnozems occur on the upper slopes and benches. Lithosols occur on basinite outcrops.
Fountaindale Depositional Low rolling hills with long sideslopes on Budgong Sandstone in the Jamberoo Valley. Broad drainage plains (20%. Extensively cleared with cattle grazing and hobby farming the main landuses Moderately deep (50 to 100 cm) Brown Podzolic Soils and Yellow Podzolic Soils.
Illawarra Escarpment Colluvial Steep to very steep slopes of Quaternary talus. Relief 100 to 300 m. Slope gradients 20 to 50%. Large surface and subsurface sandstone boulders (2 to 25 m wide) are common. Mostly uncleared with conservation and mining the main landuses. 2Deep colluvial soils. Red Podzolic Soils and Brown Podzolic Soils occur on midslopes. Silaceous Sands occur along drainage lines. Lithosols occur where the talus is recent.
