The wise management of Australia's biodiversity has major economic and social benefits for the nation through the provision of ecosystem services, bio-products and tourism. Fire is a pivotal environmental factor that will continue to influence plant biodiversity in fire-prone ecosystems. Inappropriate fire regimes, however, threaten biodiversity through disruption of life cycles. If too many or too few fires occur in an area this can lead to decline and extinction of plant and animal species. This research will provide a risk-assessment tool for the management of biodiversity to reverse population declines and prevent extinctions.

通过提供生态系统服务、生物产品和旅游业，对澳大利亚生物多样性的明智管理为国家带来了重大的经济和社会效益。火灾是一个关键的环境因素，将继续影响易火生态系统中植物的生物多样性。然而，不适当的火灾制度会破坏生命周期，从而威胁到生物多样性。如果一个地区发生太多或太少的火灾，这可能导致动植物物种的减少和灭绝。该研究将为生物多样性管理提供风险评估工具，以扭转种群数量下降和防止灭绝。
