Ind...Dendrochronological analysis of fire scars requires tree survival of fire exposure. Trees survive fire exposure by: (1) avoidance of injury through constitutive protection and (2) induced defense. Induced defenses include (a) compartmentalization processes that resist the spread of injury and infection and (b) closure prmesses that restore the continuity of the vascular cambium after fire injury. Induced kfenses are non-specific and are similar for fire and mechanical injury. Dissection of central hardwood species in a prescrihd fire treatment area in southeastern Ohio provided an opporiu~ty to place features seen in dendrochronological mp1es into their biological mntext. Terms for these features are proposed and funher discussion is solicited.Read More
