An underburn in a pine overstory is a carefully managed, low-intensity fire that moves through surface fuels beneath mature pine trees. These forests evolved with frequent fire, which historically reduced needle litter, small saplings, and brush that compete with larger trees. By reintroducing good fire under the right weather and fuel conditions, land managers reduce hazardous fuel buildup, protect tree crowns from high-severity wildfire, and improve overall forest structure. Underburning also recycles nutrients into the soil, stimulates native grasses and forbs, and enhances wildlife habitat. When properly planned and implemented, pine underburns strengthen long-term resilience and maintain healthy, fire-adapted landscapes.
