Litter flammability of ravine and upland tree species, sorted by maximum flame height.

aMoisture metrics for the ravine species were collected in part from Kreye et al. (2013), moisture metrics for upland species were not collected as part of the Kane et al. (2008) study and so are unavailable.bRavine species’ flammability data were collected as part of this study, upland species flammability data are from Kane et al. (2008).
