Fires have increased in frequency around the world and are a catalyst for environmental change. By examining wildfire impacts within watersheds, we can use system response and recovery from wildfire as a means for investigating lateral movement of life and biogeochemistry across landscapes under changing conditions. There remains a significant knowledge gap in cross-disciplinary analyses investigating how fires impact watershed processes at the landscape level. Wildfire disturbances may impact water quality, hydrology, total biodiversity, ecosystem services, wildlife habitat, soil biogeochemical cycles, plant community composition and ecosystem function, surface albedo, and impact feedbacks to surface energy fluxes that exacerbate future fire probability. In this session we invite research examining these impacts after natural and anthropogenic fire. We emphasize watersheds where fires are expected to increase under future climate conditions and shift ecosystem structure. We seek contributions using novel statistical, analytical, experimental, field, molecular, remote sensing, and modeling techniques.
