Mallee Woodlands and Shrublands

Mallee Woodlands and Shrublands (MVG 14) is a Major Vegetation Group which occurs in semi-arid areas of southern Australia.[1] The vegetation is dominated by mallee eucalypts which are rarely over 6 metres high. Other dominant plant genera are Melaleuca, Acacia and Hakea.[1]

The composition of the understorey depends on factors such as rainfall, soil composition as well as fire frequency and intensity. In subhumid areas, a variety of grasses and shrubs predominate, while in semi-arid areas hummock grasses (Triodia species) predominate.[1]

In 2001, the area covered by this vegetation group was estimated to be 65% of its pre 1788 coverage.[2] The most extensive extant area of this group in Australia today is found in the Great Victoria Desert. Prior to 1788, the largest area occurred in the Murray-Darling basin.[1]

The Major Vegetation Subgroups for this group are:
