Physical Condition of Surface Soil
Department for Environment and Water
Physical condition of surface soil mapping highlights areas where plant growth may be impeded due to poor surface soil structure, predominantly due to a condition known as hard... -
Emergency Location Markers
Department for Environment and Water
Data layer includes emergency location markers (point locations) within DEW parks. Each emergency location marker (ELM) carries an alpha numeric code made up of three letters... -
Surface Soil Acidity (ASRIS)
Department for Environment and Water
Soils are classified according to the pH of the surface layer, according to the lower pH values recorded among similar soils, i.e. it is assumed that each soil class has a... -
Marine Park Network Boundaries
Department for Environment and Water
This dataset identifies the land and waters within the SA Marine Parks Network Zoning which is dedicated to conservation under the Marine Parks Act 2007. The South Australian... -
Vegetation Heritage Agreements

The boundaries of Native Vegetation Heritage Agreements areas. These Heritage Agreements are privately owned and legally recognised under the Native Vegetation Act 1991, and... -
Recreation Trails
Department for Environment and Water
This data layer includes trails, which generally consist of a formed pathway on the ground surface. Portions of some long distance trails which coincide with vehicular tracks or... -
Soil Alkalinity
Department for Environment and Water
Alkalinity is usually an inherent characteristic of soils, and alkaline soils are largely confined to areas with less than 400 mm annual rainfall. Mapping shows surface and... -
Inherent Soil Fertility
Department for Environment and Water
Inherent fertility is a relative indicator of the soil's capacity to retain and release nutrients for uptake by plants, and is associated with clay and organic matter content.... -
Surface Water Subcatchments
Department for Environment and Water
The sub-catchment layer contains boundaries of discrete areas within catchments that each defines the watershed of a major tributary or tributaries. Attributes include the names... -
Land Use Potential for Canola
Department for Environment and Water
Land use potential for Canola: based on soil and landscape attributes only. The relative potential to sustain particular crops is predicted from expert assessment of plant... -
Scalding (soils)
Department for Environment and Water
Scalding refers to land, primarily in low rainfall environments, where the surface soil has been eroded to expose sub-surface material that is unsuited to plant growth. Mapping... -
Landscapes SA Boundaries
Department for Environment and Water
The Landscape South Australia Act 2019 replaces the Natural Resources Management Act 2004.The new regional landscape boundaries are proposed to better align regions with... -
Native Vegetation Floristic Areas - NVIS – Statewide

This dataset represents the State Government's key extant native floristic vegetation mapping layer for SA. It provides floristic and structural information (referred to as... -
Depth to Hard Rock (soils)
Department for Environment and Water
Hard rock is basement rock or bedrock that is too hard to dig with hand tools (and does not include hardpans). Mapping shows the average estimated depth to hard rock, while... -
Ramsar Wetland Areas - South Australia

This dataset identifies the boundaries of the 6 areas listed in the Ramsar Convention for South Australia. All wetlands within these areas are of international importance are... -
Soil Sodium Toxicity (depth to toxic layer)
Department for Environment and Water
High natural levels of sodium, that are toxic to some plants, are typically associated with deep subsoil sodicity, high pH, high boron and moderate salinity, and occur mostly in... -
Soil Wind Erosion Potential
Department for Environment and Water
Wind erosion potential, based on Soil Landscape Map Units of Southern South Australia, describes the susceptibility of land to erosion by wind, which is particularly an issue on... -
Soil Surface Carbonate
Department for Environment and Water
Surface carbonate often occurs as finely divided particles which reduce nutrient availability to plants and retard the degradation of some herbicides. Mapping shows the... -
Surface Soil Texture
Department for Environment and Water
Surface texture (which refers to approximate clay content) influences many important soil qualities such as waterholding capacity, fertility and erodibility. Mapping shows the... -
