“…In addition, remnants are often subject to altered fire regimes due to increased fire frequency due to arson (Stenhouse 2001;Hero et al 2013) and increased fire frequency and severity due to invasion by fire-promoting weeds (Crosti et al 2007;Fisher et al 2009;Ramalho et al 2014). These altered fire regimes combine with other disturbances, such as edge effects (Urbina- Cardona et al 2006;Garden et al 2007;McAlpine et al 2015), to further alter vegetation structure (Ibanez et al 2017;Gomes et al 2022). In combination, these pressures, along with a changing climate (How et al 2022), have the potential to strongly influence post-fire responses of reptiles in urban remnants.…”

Background Reptile responses to fire may differ between remnants and contiguous vegetation but this is poorly understood. Aims We aimed to explore long-term (≤15 years) post-fire responses of reptiles in an urban Banksia woodland remnant. Methods We trapped reptiles for 10 nights in November and December each year between 2009 and 2023 inclusive (except 2014 and 2019) to estimate relative abundance. We used mixed models to explore differences between unburnt and burnt sites and changes in both over time. Key results and conclusions The reptile community showed short-term negative responses to fire, but communities had returned to their pre-fire state within 3 years. Two species showed short-term (3 and 5 years respectively) negative responses to fire while two species showed positive responses; one in the first year post-fire only, and the other in sites >8 years post-fire. There did not appear to be consistent differences in fire responses between this study and studies conducted in contiguous Banksia woodlands, although differences in study designs renders this conclusion equivocal. Implications Reptile communities in Banksia woodland remnants, and the species they contain appear to be relatively robust to a wide range of fire regimes.
