AGU: Wildfires can burn hot without ruining soil, new study finds
A new study found that large, hot fires do not necessarily lead to scorched soil. Instead, the soil temperature is affected by factors such as fire speed, heat travel direction, and landscape moisture content. This counterintuitive result could help forest managers plan controlled burns more effectively.
Air pollution diminishing air quality at Devils Postpile National Monument
A recent study published in Atmospheric Environment found that air pollution from wildland fires and urban areas is reducing air quality at Devils Postpile National Monument. Ozone concentrations exceeded California standards, posing a risk to sensitive individuals, and may have phytotoxic effects on plants.
Best and worst times to start a fire
Early season prescribed burns, such as those conducted by the NASA-backed Ecofire program, are more effective at containing fires and reducing long-term damage. By mimicking traditional Aboriginal fire practices, these early-season burns can help reestablish vegetation and prevent the formation of extensive burn scars.
