Table 7 Recommended management guidelines for using Ryan (1982) bark char codes as a surrogate for direct cambium sampling after fire. Species/code combinations not listed are not clearly associated with either live or dead cambium and should be sampled directly to determine injury.

  1. a If pre-fire duff mound depths are high and most of the duff is consumed in the fire, then the probability of cambium mortality is higher.
