Salinity Province 30, East Dundas Tablelands

Thumbnail image showing the location of East Dundas Tablelands Salinity Province in VictoriaThe East Dundas Tablelands is a large Salinity Province of about 200,000 ha with nearly 5000 ha of mapped dryland salinity occurrence, primarily found along drainage lines, ‘break-of-slope’ and hillside seepage areas, depending upon the Groundwater Flow System (GFS) responsible. The main GFS is deeply weathered and very old volcanic ‘ignimbrite’ bedrock of intermediate scale, with the overlying weathered regolith layers forming local GFSs containing groundwater with salinity ranging from 5000 mg/l to 15,000 mg/l. Groundwater levels undoubtedly increased following landscape clearance but showed a general decline during the drought years.

Recent farm forestry expansion into some areas may have been beneficial in reducing recharge and the extent of some saline discharge areas. Planting of salt and waterlogging tolerant pastures is recommended for discharge areas along with careful management of stocking to protect the often sodic soils from erosion.

1 Please Note: The ‘Recorded Soil Salinity Area’ indicated in the Salinity Province Attribute Table, comprises the total geographic area that has been mapped as having, or showing symptoms of, dryland soil salinity at some time (past or present). As dryland salinity occurrence in the Victorian landscape exhibits many different levels of severity and can change due to climate, landuse and vegetation, previously mapped areas may no longer be showing symptoms. In addition, as not all parts of the State have been mapped, or mapped in the same way, the mapping may not have captured some occurrences.

The soil salinity mapping used to calculate this ‘area’ does not cover irrigation regions. In irrigation regions, depth to watertable and watertable salinity mapping has been used to convey the threat of high watertables on soil waterlogging and/or soil salinisation and these areas are not included in this ‘area‘ calculation.

Please contact the Department, your Catchment Management Authority or your rural water provider for more information about salinity in your location.
