Climate-driven increases in area burned by wildfire have accelerated the need to understand the effects of multiple fire events on ecosystems. Our ecological understanding of this disturbance process must represent the entire fire continuum, from managed fires to wildfires, to improve our ability to forecast ecosystem response. To date, empirical data on multiple fire events are limited, with the exception of a handful of ecosystems. The ecological response is likely to vary as a function of fire type and ecosystem, as well as the ecosystem attributes interest. This session will include evaluation of multiple fires (both managed and wildfire) on a range of ecosystem attributes, including soil, plants, and elemental fluxes. Further, this session will represent a diversity of ecosystems, from tropical to boreal, at a range of spatial scales, from the patch to the region.
