Table 1 Fire and site-level characteristics for study reaches in Yosemite National Park, California, USA (modified from Jackson and Sullivan 2015). Channel-reach morphology was classified following Montgomery and Buffington (1997). Stream order was determined based on Strahler (1957). Aspect was used as a coarse proxy for heat load (McCune and Keon 2002). Streamwater was sampled from the sites between 1 and 13 years after the last fire
