Wildfire Impacts on Watershed Biogeochemistry, Hydrology, and Biodiversity
Session ID#: 250867
Session Description:
Wildfires 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, resilience, and recovery from wildfire as a means for investigating lateral movement of life and biogeochemistry across landscapes. There remains a significant knowledge gap in cross-disciplinary analyses investigating how fires impact watershed processes from the genomic, molecular, field, to the landscape level. Wildfire disturbances may impact water quality, hydrology, microbial community composition, geomorphology, total biodiversity, organic matter chemistry, ecosystem services, wildlife habitat, soil biogeochemical cycles, plant community composition, 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 (wild)fire, including prescribed burns, and work that incorporates traditional knowledge. We seek contributions using novel statistical, analytical, experimental, field, molecular, remote sensing, and modeling techniques.
