Advice on how to minimise potential negative impacts of, and following on from, the subdivision

What do we mean?

Subdivision activities can have a wide range of impacts on threatened species. 'Subdivision' includes all activities associated with the subdivision of land for residential or other development purposes. The effects of a subdivision can occur well outside the actual footprint of the activity.

General points to consider

  • Subdivision is a significant threatening process for many threatened plants and animals, and is a major cause of habitat loss.
  • Direct impacts to threatened species of a subdivision can include the partial or total removal of native vegetation, altered drainage works, introduction of weeds and diseases, and damage to waterways.
  • Subdivision of a property also involves the potential for on-going impacts after subdivision works are completed. These indirect impacts may extend well beyond the footprint of the subdivided property.
  • Additional impacts include predation and disturbance of threatened fauna from an increase in domestic animals, the escape of non-native plants (from gardens, nature strips, etc) into adjacent bushland, on-going noise disturbance to adjacent areas, competition and predation from exotic animals such as rats and mice, and the pollution of waterways through refuse and contaminated run-off.
  • Housing developments adjacent to native bush can also lead to an increase in burning through deliberate lighting of fires, as well as inadvertent ignition.
