From: An added boost in pyrogenic carbon when wildfire burns forest with high pre-fire mortality
A conceptual framework of how post-fire legacies and pyrogenic carbon (PyC) influence ecosystem functions. The concentration of PyC was greater on beetle-killed snags (left) compared to fire-killed snags (right), creating an ecological legacy that has the potential to function differently. Beetle-killed snags are architecturally distinct from fire-killed snags, further contributing ecological differences. Forest conditions where a substantial number of beetle-killed snags burn and produce heavily charred snags could influence ecosystem processes that operate through deadwood including decomposition, microbial activity, nutrient cycling, and resources for insects and birds
