Long-term effects of prescribed fire on mixed conifer forest structure in the Sierra Nevada, California
The authors monitored prescribed fire in old-growth mixed conifer stands for eight consecutive years to examine the long-term effects on forest structure and how the actual results compared to restoration objectives.
The authors found that prescribed fire can affect forest structure for five or more years post-treatment. Delayed tree mortality was observed up to eight years post-fire causing a 67% reduction in stem density within the time period of the analysis. The authors suggest that long-term, prescribed fire can alter stand structure in old-growth mixed conifer forests.
