Data supporting: Success of post-fire plant recovery strategies varies with shifting fire seasonality

Wildfires are increasing in size and severity and fire seasons are
lengthening, largely driven by climate and land use change. Many plant
species from fire prone ecosystems are adapted to specific fire regimes
corresponding to historical conditions and shifts beyond these bounds may
have severe impacts on vegetation recovery and long-term species
persistence. Here, we conduct a meta-analysis of field-based studies
across different vegetation types and climate regions to investigate how
post-fire plant recruitment, reproduction and survival are affected by
fires that occur outside of the historical fire season. We find that fires
outside of the historical fire season may lead to decreased post-fire
recruitment for many species, particularly obligate seeding species.
Conversely, we find a general increase of post-fire survival in
resprouting species. Our results highlight the trade-offs that exist when
considering the effects of changes in the seasonal timing of fire, an
already present aspect of climate-related global fire regime change.
