Situated in the southeast to central parts of Victoria, the West Gippsland CMA Region is bounded by the Victorian Great Dividing Range in the north and Gippsland coast in the south. Major landform elements in the region where salinity problems tend to be found include the coastal areas of Wonthaggi – Inverloch, Corner inlet – Yarram coast and the Macalister – Lake Wellington areas at the eastern end of the Latrobe Valley.
The region has a Mediterranean climate with maximum temperatures and minimum rainfall occurring in summer. This is tempered in coastal areas creating milder temperatures and a more evenly distributed annual rainfall. The mean annual precipitation varies considerably with elevation, with upland areas sometimes receiving three times the rainfall of lowlands. Annual average precipitation ranges from less than 700 mm at Sale to over 1300 mm at Erica.
The majority of the lowland and coastal southern half of the region has been cleared for agriculture, with the predominant land-use grazing. Public land retained under forest occurs in the upland northern part as well as in significant parts of the Strezlecki ranges, along with substantial plantations.
Dryland salinity occurrence is often associated with high watertables in coastal areas, or with cleared catchments and break-of-slope Groundwater Flow Systems in more elevated farming locations. The Macalister Irrigation Region around Maffra and Sale has high watertables and some salinity management issues similar to those found in the northern Victorian irrigation areas.
Salinity has been recorded at over 260 individually mapped units1, with a total area of approximately 16,770 hectares1 . Across the region, eight Salinity Provinces (including five 'High' priority Provinces) have been defined based on these salinity occurrences. Three of these Provinces are found inland and the other 5 adjoining the coast.
The West Gippsland CMA has an extensive range of online materials (maps and documents etc.) which outline the biophysical assets of the catchment, as well as their major risks (including soil and water salinity). This material also outlines the programs and projects currently being completed by the CMA to protect and enhance these assets. An example of this is the West Gippsland CMA ‘Waterway Strategy 2014 - 2022’, the link to which can be found at the base of this page.
