season, and types (aerial/subterranean) of successive fire events at a point in the landscape (DAWE 2022). Fire regimes that cause biodiversity decline in temperate grassland communities on the Victoria Volcanic Plain, where Spiny Rice-flower predominantly occurs, have been identified as low fire frequency and fire-competition interaction (DAWE 2022). Low fire frequency (long intervals between fires) cause decline in these populations directly by failing to trigger essential life-history cues to habitat suitability, or through interactions with other threats such as fragmentation (DEWHA 2009; TSSC 2016; DAWE 2022). Traits sensitive to low fire frequency include a combination of short-lived seed banks and low seed-dispersal range (DAWE 2022).

b) Categories for consequences are defined as follows:
Not significant – no long-term effect on individuals or populations
Minor – individuals are adversely affected but no effect at population level
Moderate – population recovery stable or declining
Major – population decline is ongoing
Catastrophic – population trajectory close to extinction
