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 (
Wattamolla Road Depositional Long gently to moderately inclined sideslopes and undulating to rolling hills with broad benches on Budgong Sandstone. Relief 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 (>150 cm) Prairie Soils occur on crests and upper slopes, Brown Krasnozems on the midslopes and Red Podzolic Soils and Prairie Soils on the lower slopes and drainage plains.
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 Deep (>150 cm) Krasnozems present on the crests and upper slopes with Prairie Soils on the lower slopes.
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.
Jamberoo Residual Rolling latite hills with broad crests and ridges. Relief 100 to 200 m with slope gradients Deep (>150 cm) Krasnozems occur throughout this landscape with Structural Loams localised on Saddleback Mountain.
Fountaindale Depositional Low rolling hills with long sideslopes on Budgong Sandstone in the Jamberoo Valley. Broad drainage plains ( Moderately deep (50 to 100 cm) Brown Podzolic Soils and Yellow Podzolic Soils.
Albion Park Erosional Short steep upper slopes with long gentle footslopes on Berry formation. Relief is 60 to 100 m. Slope gradients 5 to 15% on footslopes and 15 to 50% on upper slopes. Mostly cleared with some stands of tall open forest. Moderately deep Brown Podzolic Soils on crests, Yellow Podzolic Soils on midslopes and Soloths on footslopes and drainage lines.
Mangrove* Creek Estuarine Vegetated tidal flats in estuarine areas on Holocene sediments. Relief 3%. Deep (>150 cm) Siliceous Sands, Calcareous Sands and Solonchaks occur on Mangrove Flats with Humic Grey Soils and Solonchaks on saltmarsh
Shoalhaven* Fluvial Level to gently undulating riverbed and banks, active floodplain with levees and backwater swamps on alluvium. Flat to gently undulating terrace surfaces of the Shoalhaven River. Relief Moderately deep (50 to 100 cm) Prairie Soils on levees; Red Earths and Yellow and Red Podzolics Soils on terraces; and Alluvial Soils and Gleyed Podzolic Soils on the floodplain.

* The occurrence of Zieria granulata sites within the Mangrove Creek and Shoalhaven soil landscape units is considered to be highly unlikely.
