In summer 2021 we looked at impacts of heat from fire on Pseudotsuga menziesii var. glauca saplings. At moderate to high fire intensity doses (84% fire-induced mortality) we saw living xylem and damaged phloem after 6 weeks.

Some of our recent published research in ponderosa pine saplings showed that its more likely that cambium and phloem damage that impacts NSC transport, rather than xylem hydraulic failure, is responsible for fire-induced tree mortality.
