Salinity Province 79, Morkalla

Thumbnail image showing the location of Morkalla Salinity Province in Victoria The Morkalla Salinity Province is a smaller province on the South Australian border and is predominantly covered with remnant vegetation with only a small area of cropping in the northeast.

As with all Mallee provinces, a regional scale Groundwater Flow System comprising marine and alluvial origin sediments underlies it and structural (geologic) control on groundwater discharge and the natural salinity occurrences is evident. It has mainly primary salinity, with natural salt scalds in groundwater discharge depressions found in amongst the Mallee dune landforms.

Land management practices in respect to salinity are to avoid areas of primary salinity and protect remnant vegetation and salinised soils from grazing.

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.
