Session Proposal: Critical Zone Response and Resilience to Wildfires (AGU25)

H055
Critical Zone Response and Resilience to Wildfires

Session ID#: 250885

Session Description:
Wildfires act as catalysts for reshaping landscapes and altering ecosystem functions and services. While these disturbances are considered fundamental ecosystem processes, recent increases in fire intensity and frequency have raised concerns about potential negative feedbacks of fires on ecosystem structure and functioning. Critical Zone (CZ) research has assessed and reported important findings on the impacts of these disturbances on catchment-scale processes (e.g., hydrology, water quality, geomorphology, biogeochemical cycles). While these investigations have fundamentally increased our knowledge of the immediate effects of fires at the landscape level, studies are needed to understand longer-term consequences for CZ evolution over pedogenic and geomorphic timescales, including how CZ structure and dynamics may contribute to conferring ecosystem resilience. We invite contributions that address the impacts of wildfire on CZ structure and evolution, and water, nutrient, and carbon cycles in response to wildfires, and how these linkages regulate ecosystem resilience and resistance to these stand-replacing events.
