Weeds are plants (not necessarily non-native) that grow in sites where they are not wanted and which have detectable environmental or economic impacts.

The role of DBCA’s Parks and Wildlife Service in managing weeds (invasive plants) is to:

  • Minimise the impacts of weeds on biodiversity, especially on threatened flora, fauna and ecological communities which are most vulnerable to their impacts.
  • Minimise the impact of weeds on cultural heritage sites, the amenity of public recreation areas and the aesthetic appeal of our natural environment for the appreciation and benefit of current and future generations. 
  • Minimise the impact of weeds on fire behaviour and fire regimes through hazard mitigation strategies and utilise opportunities to undertake post-fire weed control to facilitate regeneration of native species. 
  • Minimise the spread of priority weeds onto lands adjacent to Parks and Wildlife Service-managed lands.
