Climate-driven natural disturbances and wildfire regimes: Enhancement of ecosystem resilience

This review synthesises evidence on how climate change alters disturbance regimes, how wildfire interacts with other natural disturbances, and which management responses are most likely to sustain ecosystem resilience. Literature was retrieved from major academic databases and search platforms, screened using explicit eligibility criteria, and synthesised narratively. The review was guided by the Scale for the Assessment of Narrative Review Articles (SANRA). Thirty-seven (37) core studies formed the principal evidence base, supplemented by recent comparative literature used to strengthen interpretation. Across biomes, wildfire–drought interactions emerged as the most consistently documented pathway of resilience decline, commonly reducing regeneration, accelerating vegetation stress and shifting community composition. Interactions with windthrow and insect outbreaks also amplified structural damage and altered fuel conditions, although their effects depended strongly on disturbance sequence, timing and severity. Recent work on megafires, prescribed burning and fire–flammability feedbacks further shows that management cannot rely on single-disturbance assumptions. Instead, resilience depends on maintaining structural and compositional diversity, anticipating cascading effects, and aligning interventions with future climate trajectories. Overall, interacting disturbances research indicates that climate adaptation must move beyond suppression-focused strategies toward context-specific, ecologically informed management.
