Vegetation Mapping

Victoria’s native vegetation communities are being progressively mapped in a statewide program coordinated by the DSE Flora and Fauna Program. Detailed vegetation community mapping is being produced using EVCs. Descriptions of these detailed EVC communities are not yet available for all of the State, so interim BVTs have been prepared for illustrating issues and establishing priorities at the Statewide and CMA levels.

Bioregions are elements of a new natural framework based on the patterns of ecological characteristics in the landscape or seascape, allowing us to recognise and respond to biodiversity values. Eighty-one bioregions have been identified for Australia, 21 identified in Victoria. Eight classified Victorian bioregions are found wholly or partly within the Glenelg-Hopkins Catchment Management Region:

1. Central Victorian Uplands
2. Dundas Tablelands
3. Glenelg Plain
4. Goldfields
5. Greater Grampians
6. Victorian Volcanic Plain
7. Warrnambool Plain
8. Wimmera

Each bioregion contains a number of BVTs, which have been mapped at 1:250 000 scale at the statewide level. They have been developed on the basis of land systems and other factors including typical vegetation, geology, rainfall, elevation and soil type. BVT’s are not bioregion specific, and the same BVT may occur in more than one bioregion. They are useful at the regional level to provide an overview of the selective depletion of native vegetation as a result of European occupation and use of the landscape.
