Natural Environment

Are you interested in supporting or exploring the natural environment of Brimbank? There are a number of ways to get involved including:

The Brimbank Patch

Our natural environment consists of living (plants and animals) and non-living things (rocks, wind, topography, water). Brimbank's landscape of flat plains and steep river escarpments was formed by volcanic activity.

The Victorian Volcanic Plains

Our municipality lies within the Victorian Volcanic Plains (VVP) Bioregion, which – prior to European settlement – was covered in highly productive grasslands, wetlands, and woodlands.

Patches of VVP Natural Temperate Grasslands ecosystem remain throughout the municipality and are listed as critically endangered under the federal Environment Protection Biodiversity Conservation Act (1999).

Water-formed Valleys

Our volcanic plains are divided by the deep valleys of Jacksons Creek and the Maribyrnong River, to the north and to the east. The valleys of Taylors Creek and Steele Creek deepen as they join with the Maribyrnong River.

At the southern end of our municipality the shallower, but well-defined, valleys of Jones Creek, Kororoit Creek and Laverton Creek divide the plains.

Our area is characterised by shallow soils, strong winds, and low rainfall (annual average 400-500mm).

Flora and Fauna

Brimbank supports more than 500 indigenous plant species and 196 animal species. Many are considered rare, threatened, or endangered. Several of these plants and animals form part of the critically endangered Plains Grasslands ecosystem – there’s now less than 1 per cent remaining across Victoria.​

Ecological Burn Program

We keep Brimbank’s natural environment healthy with a bi-annual ecological burn program (autumn and spring), pending weather conditions. 

It helps

  • maintain healthy ecosystems;
  • encourage native plant growth; and
  • rejuvenate habitat for native animals.

The program is a key part of our Biodiversity Strategy and helps manage our unique landscape.

To ensure the burns are safe and effective, we

  • assess Brimbank’s native grasslands to see if management is needed; and
  • check sites to work out the most suitable weather and area conditions.

We sometimes change our burn schedule to take advantage of these conditions.

We notify nearby residents and stakeholders before we start the program.
