Conceptual model for assessing a science-policy-management framework for threat mitigation.

Area of Science:

• Ecology and Conservation Biology
• Environmental Management and Policy

Background:

• Globally changing fire regimes necessitate management interventions that balance human safety with biodiversity conservation.
• Existing policies aim to mitigate threats from high-frequency fire (HFF) to threatened flora, but their effectiveness requires evaluation.

Purpose of the Study:

• To conceptualize a framework for addressing threats to flora from changing fire regimes.
• To evaluate the effectiveness of current policies in identifying and mitigating high-frequency fire (HFF) threats to threatened species.
• To identify areas for improvement in threat identification, policy design, and action implementation.

Main Methods:

• Development of a 5-aspect conceptual model for managing flora threats.
• Case study application in southeastern Australia examining policy for hazard reduction burns and threatened flora.
• Analysis of species threat identification, policy inclusion, and HFF incidence reduction post-policy implementation.

Main Results:

• Most threatened species were accurately identified, and the policy generally minimized HFF threats.
• Significant gaps were found: 96 species lacked HFF threat identification, and 36 were omitted from policy.
• Despite a 2-year increase in fire intervals, 55% of studied species were impacted by HFF post-policy, showing species-specific outcomes.

Conclusions:

• While minor improvements in threat identification and policy design are possible, action implementation shows mixed success, indicating limitations.
• The conceptual model provides a clear framework for targeted recommendations to improve policy and management strategies.
• The proposed model is adaptable for diverse contexts facing similar fire management challenges.
