In 2020–21, the Monitoring, Evaluation and Reporting Framework for Bushfire Management on Public Land continued to be delivered through our Victorian Bushfire Monitoring Program. This included monitoring fuel levels and ecosystem resilience. This monitoring program data allows us to determine how effectively planned burning reduces fuel, and to evaluate our progress in reducing bushfire risk.

Fuel hazard monitoring

Fuel hazard monitoring provides important information about planned burns including the severity and coverage of each burn, how it has reduced fuel hazard, its success in achieving ecological burn objectives where appropriate, and if follow-up actions are required. We set burn objectives to achieve a balance between fuel reduction and preserving important values. For example, a burn objective may be to achieve 70 per cent burn coverage within the footprint of a planned burn to ensure that sufficient refugia, habitat and food sources are left for flora and fauna.

When evaluating a planned burn, we inspect a series of plots. Some fuel hazard assessment sites may be in areas intentionally left unburnt to provide refuges for animals in the planned burn area.

Table 1 shows the overall fuel hazard monitoring effort for 2020–21.

Ecosystem resilience monitoring

Below shows the ecosystem resilience monitoring and related activities we undertook in each region. Monitoring was mostly of the before-and-after impacts of planned burns on important local values.

In 2020–21, we continued to deliver our statewide ecosystem resilience monitoring program in partnership with the Bushfire Natural Hazards Cooperative Research Centre (now Natural Hazards Research Australia), La Trobe and Deakin Universities, and the University of Melbourne. From the program’s commencement until 2020-21, we have invested in excess of $900,000 per year to deliver against a La Trobe University designed monitoring strategy and methods that measure the effects of fuel management and bushfires on ecosystem resilience.

The statewide ecosystem resilience monitoring program collects data about flora, habitat, birds, and mammals in 11 priority ecosystems across Victoria. Data collection is currently underway in eight of these ecosystems, with the remaining three due to commence shortly. This work will increase our knowledge of ecosystem and species responses to fire and improve fire management through evidence-based decisions. We will continue to analyse the data from the 11 priority ecosystems over the next few years, and we will use it to improve models and tools for bushfire management reporting and decision-making across the state.
