This document synthesizes existing knowledge on reintroducing fire into long-unburned, fire-dependent forests of the United States, specifically focusing on how to minimize mortality of large, old trees. Historically, these ecosystems experienced frequent, low-intensity fires, which kept fuel loads low and fostered fire-tolerant species. However, over a century of fire suppression has led to unprecedented accumulations of deep duff and increased tree densities, making reintroducing fire a complex challenge that can paradoxically harm the very old trees practitioners aim to protect. The document delves into causes of tree injury and mortality from fire, such as basal cambium damage from smoldering duff and subsequent bark beetle attacks, and explores various management options including prescribed burning with the aim of restoring historical forest conditions and preserving venerable trees.
