This data deal with hydrogeological landscapes of the ACT and the nature and consequences of salinity in the ACT 1:50000. They have been produced for the ACT Government by the NSW Office of Environment and Heritage (OEH) and NSW Department of Primary Industries (DPI). The maps and document result from a series of salinity projects OEH is undertaking to better understand how dryland salinity manifests in the landscape and how salinity may be best managed. The full ACT HGL dataset includes the following: Hydrogeological Landscapes Hydrogeological Landscape Management Areas Land and Soil Capability (Overall) Salinity Hazard (Overall) ACT Erosion Hazard (Current) ACT Erosion Hazard (Future Consensus Scenario) ACT Erosion Hazard (Future Worst Case Scenario) ACT Erosion Hazard (Future Best Case Scenario) Wetland Vulnerability Classification Wetland Types (Australian National Aquatic Ecosystem)

This digital soil landscape product contains natural resource mapping for the Australian Capital Territory. The project was funded by the ACT Government to enhance knowledge of soils, landscapes and physical constraints to land use in the urban and rural environment. The information will assist in informed decision making, planning and environmental modelling throughout the catchment. Fifty-five soil landscape map units have been described for the ACT. Each unit is an inventory of soil and landscape information with relatively uniform land management requirements, allowing major soil and landscape qualities and constraints to be identified. Soils are described using the Australian Soil Classification and the Great Soil Groups systems. Related datasets: Part of this area is also covered by the Soil Landscape 1:100 000 mapping series for the mapsheets of Canberra and Michelago. Online Maps: This and related datasets can be viewed using eSPADE (NSW’s soil spatial viewer), which contains a suite of soil and landscape information including soil profile data. Many of these datasets have hot-linked soil reports. An alternative viewer is the SEED Map; an ideal way to see what other natural resources datasets (e.g. vegetation) are available for this map area.

This digital soil landscape product contains natural resource mapping for the Australian Capital Territory. The project was completed by the Office of Environment and Heritage (NSW). The project was funded by the ACT Government to enhance knowledge of soils, landscapes and physical constraints to land use in the urban and rural environment. The information will assist in informed decision making, planning and environmental modelling throughout the catchment.55 soil landscape map units have been described for the ACT. Each unit is an inventory of soil and landscape information with relatively uniform land management requirements, allowing major soil and landscape qualities and constraints to be identified.The GIS product shown here provides location of each of the soil landscape map units - including the soil landscape code and name. For more detailed information please see the full soil landscape reports for each unit, as well as the final report (seedatasets.seed.nsw.gov.au). Detailed spreadsheets can be used to join more detailed information to the GIS also available on request.Lineage:The mapping undertaken by the NSW Government was created using:existing published soil landscape mapping (Canberra and Michelago 1:100,000 map sheets);new soil landscape mapping (part Brindabella and Tantangara 1:100,000 map sheets).For all datasets, provisional soil landscapes were established firstly on the dominant geomorphic processes responsible for the formation of the landscape and secondly on the geological parent material. Elevation, aspect, vegetation patterns and human disturbance were other factors considered when defining units.For existing mapping, the boundaries of these provisional soil landscapes were mapped using stereoscopic interpretation of 1:40,000 scale black and white and 1:25,000 scale colour aerial photographs (Canberra) and 1:40,000 scale black and white aerial photographs only for Michelago. LANDSAT thematic mapper and radiometric imagery were used to assist with perception and charting of provisional soil landscapes. These boundaries were transferred onto 1:25 000 topographic base maps. After field checking boundaries and detailed investigations of the soil, the provisional landscapes were confirmed, amalgamated or sub-divided.For new mapping on the Brindabella and Tantangara sheets, the boundaries were captured by digitizing directly to screen at around 1:10,000 scale using ArcGIS. Ultra-high resolution (10 cm) aerial photographic imagery provided a base layer during the capture process. In addition the following data were used to assist delineate soil landscapes boundaries: ADS digital aerial imagery, radiometric imagery, SPOT 5 satellite imagery, climate data, 1 second DSM and DEM elevation data from the Shuttle Radar Topographic Mission (SRTM), 1:100,000 scale geological mapping, 1:25,000 topographic maps and DTDB digital terrain models.Soils have been examined and described in detail at over 500 sites in the ACT. This includes 79 new detailed sites to fill data gaps for this project. At each site, soil morphological data and site information were recorded on Soil and Land Information System (SALIS) cards or digitally collected via the eDIRT field data collection system. Sufficient field work was undertaken within each soil landscape to identify the range of soils present and to enable their distribution within the landscape to be described. To best knowledge none of the sites were randomly sampled. Sample intervals were selected to be morphologically representative examples of each soil material present in each type profile i.e. soil horizons.A comprehensive suite of soil tests have been analysed for many of the representative type soil profiles within the ACT.A desktop review of published soil landscape units has occurred resulting in some minor amendments to the existing linework.Positional Accuracy:Observations and soil profiles were located using handheld GPS or using 1:25,000 topographic maps.

This feature layer shows the extent of native, threatened and exotic grasslands in the ACT. Native grasslands of the Territory include a rich assemblage of flora and fauna species that combine into a unique ecosystem. These grasslands are a priority for protection and management as they contribute to our natural biodiversity, our history and heritage, and local amenity and community. Natural temperate grasslands are an Endangered Ecological Community in the ACT (Nature Conservation Act 2014) and Critically Endangered Ecological Community under the EPBC Act 1999. Other Native and Exotic grasslands in the ACT can also have some conservation significance as they support important populations of threatened fauna and flora.

The focus of this dataset is the Australian Capital Territory (ACT). It contains digital spatial data developed to assist in land management decision making in the ACT. The dataset contains hazard ratings for land salinity, stream salt load and stream EC as well as overall salinity hazard for each HGL unit. Information about landscape functions and appropriate salinity management strategies are also listed. Hyperlinks to full management descriptions for each HGL unit are provided. The Hydrogeological Landscape (HGL) concept provides a structure for understanding how differences in salinity are expressed across the landscape. A HGL spatially differentiates areas with similar salt stores and pathways for salt mobilisation. The process of delineating a HGL relies on the integration of a number of causative factors: geology, soils, slope, regolith thickness, and climate; an understanding of the different modes of salinity development; and the impacts of salinity within landscapes (land salinity, salt load and salt concentration in streams due to salt contributions from base flow and runoff ). Information sources such as soil landscape maps, site characterisation, salinity occurrence maps, hydrogeological data, surface water and groundwater data are incorporated into standardised unit descriptions.Fit for purpose: This dataset was captured at 1:25,000 scale. This dataset is fit for use as a tool for assessing land management issues at the paddock-scale in the ACT, but this does not negate the need for site assessment at a scale suitable to any potential land use or development under consideration. The mapping was mapped in 'GDA1994 MGA Zone 55s' and transformed to GDA2020 MGA Zone 55s.Credits: Rob Muller (NSW OEH), Wayne Cook (NSW OEH), Allan Nicholson (NSW DPI), Alie Cowood (UC)Disclaimer: While all care is taken to ensure accuracy, the ACT Government does not warrant that the map is free from error.
