This speedtalk by Kirstin Abley of the South Australia Department of Environment, Water and Natural Resources discusses how monitoring and habitat mapping conducted after prescribed burns and bushfires in Mount Lofty Ranges has drastically reversed thinking about the habitat requirements of the Chestnut-rumped Heathwren.

BushfireConf2017 – 10. When Preconceptions are Misconceptions – the Importance of Ecological Monitoring to Inform Prescribed Burning.
1. When Preconceptions are Misconceptions
Fire Response of the Mount Lofty Ranges Chestnut-rumped Heathwren
K. Abley, M. Pickett and
Luke C. Price
2. Ecologically informed fire
mgmt. requires knowledge
of:
- Distribution
- Fire response and
- Ecological requirements
‘Fuel’ vs habitat management in the urban interface
3. MLR Chestnut-rumped Heathwren (EPBC: Endangered)
• Small terrestrial passerine. Limited dispersal (?)
• Persists in isolated, heath dominated habitat
• Perception species requires long-unburnt habitat
• Popn viability depends on careful burn planning
4. Post-fire CRHW recolonisation
• Surveys undertaken to determine post-fire fidelity and occupancy
• Utilising habitat from 2 yrs post-burn
• Do CRHW really prefer long unburnt habitat?

7. KEY MESSAGE
Expert opinion is great but monitoring and data is better!
It’s not just about how much and how often burning occurs.
Intensity is important and low intensity isn’t always best!
