We used a ground-based approach to compute the pyrogenic carbon emissions from the Biscuit Fire, an exceptionally large wildfire, which in 2002 burned over 200,000 ha of mixed conifer forest in southwestern Oregon. A combination of federal inventory data and supplementary ground…

In a burn of 5-year-old secondary forest cleared for agriculture in Roraima, Brazil, carbon partitioning was measured for above-ground portions of both secondary forest (regrowth) and the remains of original forest, felled and burned six years previously. Above-ground dry weight…
