Salinity Province 124, Warrenbayne Boho

Thumbnail image showing the location of the Warrenbayne boho Salinity Province in Victoria The Warrenbayne_Boho Salinity Province is located on the northern flanks of the Strathbogie Ranges.

This dryland province has mostly ‘break-of-slope’ groundwater discharge associated with the colluvial fans formed from the weathering of the granitic hills, with some valley floor occurrence in the Shean’s Creek and Warrenbayne areas. This discharge may be influenced by geological structure and the effects it has had on the local to intermediate scale Groundwater Flow Systems in the region. The groundwater systems received higher recharge rates following land clearing with the resulting groundwater discharge causing secondary salinity to spread to over 1000 ha by the 1990’s.

The focus of some of the earliest actions to manage dryland salinity, this province has strong community involvement in LandCare programs that pioneered salinity control measures such as perennial pastures and ‘break-of-slope’ blue gum plantations.

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.
