Mixed species forests are widespread in Victoria, except for the north-west region. There is significant variation in the range of species involved, the soil types, elevations and climatic conditions under which these forests grow. Consequently, these forests are often referred to by a number of common names, usually based on climate or location, e.g. Dry and Lowland Sclerophyll, or Foothill and Coastal Mixed Species.
However, the division of Victorian mixed species forests into High Elevation Mixed Species (HEMS) and Low Elevation Mixed Species (LEMS) is most relevant for guiding silvicultural practices. Generally the LEMS forest type occurs in the foothills of the Great Dividing Range and in the near-coastal areas. High Elevation Mixed Species (HEMS) and Ash eucalypt species occur at higher and usually wetter sites.

Management of Mixed Species Forests - JD Kellas & RF Hateley (1989) is a good place to start in understanding this forest type.
"Let us regard the forest as an inheritance, not to be destroyed or devastated, but to be wisely used, reverently honoured and carefully maintained. Let us regard the forest as a gift, entrusted to any of us only for transient care, to be surrendered to posterity as an unimpaired property, increased in riches and augmented in blessings, to pass as a sacred patrimony from generation to generation."
Baron Ferdinand von Mueller - Suggestions on the Maintenance, Creation and Enrichment of Forests (1879)
