Salinity Province 31, Edenhope

Thumbnail image showing the location of the Edenhope Salinity Province in VictoriaThe large Edenhope Salinity Province to the south of the Little Desert National Park is characterised by its dominant NNW to SSE oriented ridgelines and intervening swales, which often contain lunette-bordered lakes of the Parilla Sand. Left behind by the retreat of the ocean several million years ago, the coastal dune landform has poorly developed surface drainage, and while it provides a regional scale Groundwater Flow System (GFS), dryland salinity is mostly natural and associated with the many small lakes and depression drainage lines at the lower landscape elevations. Overlying this is a local to intermediate scale GFSs of aeolian, alluvial and paludal sediments. With the clearance of the original vegetation, wetter climate periods resulted in high watertables under low-lying areas.

Best management practices include avoiding disturbance of known waterlogged and saline sodic soil areas and their protection from damage. Farming should concentrate effort on adjacent up-slope soils to increase perennial pastures and native re-vegetation to reduce recharge during wet periods.

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.
