Abstract: Fire is a major evolutionary and ecological driver that shapes the form and function of many forests globally. Fire can restore, modify or degrade the ecological values of forests depending on (a) the adaptive capacity of biodiversity (Clarke et al., 2009(Clarke et al., , 2013, (b) the legacy of prior disturbances and the presence of biological legacies (e.g. seeds, large old trees, resprouting plant organs; Bowd, Blair &

Background Knowledge of how fire regimes influence flammability, and its role in shaping future fire regimes, exists mostly at species composition and ecosystem levels. The effect of fire regimes on fuel at the chemical level is poorly known. Aim We aimed to empirically investigate the association between recent fire history and forest foliage chemistry; and to explore potential implications for forest fuel flammability. Methods Using an orthogonal study design, we investigated the effects of fire frequency and time since fire on the chemical composition of Eucalyptus pilularis leaves from forest canopies and surface litter in south-eastern Australia. Key results We found high fire frequency (fire-return interval 10–13 years) was associated with higher C:N, C:P, and C:K ratios in E. pilularis surface litter, and higher C:P in canopy leaves. Conclusions Nutrients including nitrogen and phosphorous reduce flammability of plant tissues, and hence, the observed differences in leaf nutrients between high and low fire frequency sites could have important implications for future flammability of these forests. Implications Our study has demonstrated a relationship between fire frequency and leaf nutrient stoichiometry, which may act as a mechanism through which repeated fires could increase fuel flammability. This warrants further investigation in other environments.
