Definition

Crown scorch height represents the vertical distance above the ground that lethal scorching of the needles or leaves in the canopy of a forest or shrubland ecosystem has occurred as a result of the heat generated from a surface fire.

Introduction

The hot, rising convective gases and radiant heat from the combustion zone of a surface fire can possibly kill the overstory foliage in a forest or brushfield without consuming the needles or leaves. This vertical dimension of lethal scorching, as typically reflected in a distinct color change, is referred to as the crown scorch height (Fig. 1). Related metrics include crown scorch volume and length expressed as a percentage of the pre-fire values (Peterson and Ryan 1986; Hood 2007b). Note that crown scorch height as used here focuses solely on...
