Helping more people get to safety in a wildfire
Wildfires pose an increasing threat to communities at the wildland-urban interface (WUI)—where dry, flammable vegetation borders backyards, often in remote locations. Despite the well-known danger, many communities at highest risk do not have a str.....»»
Twenty-year study confirms California forests are healthier when burned, or thinned
A 20-year experiment in the Sierra Nevada confirms that different forest management techniques—prescribed burning, restoration thinning or a combination of both—are effective at reducing the risk of catastrophic wildfire in California......»»
Peatlands were drained for agriculture. Now researchers are trying to restore them
With wellies and waterproof clothing, Claudia Nielsen spent time splodging through the Bois-des-Bel peatlands earlier this year. The peatlands, located in Quebec, Canada, had been restored, with conservations working on them for 23 years. Nielsen was.....»»
Climate change will increase wildfire risk and lengthen fire seasons, study confirms
Wildfires are some of the most destructive natural disasters in the country, threatening lives, destroying homes and infrastructure, and creating air pollution. In order to properly forecast and manage wildfires, managers need to understand wildfire.....»»
Private timberland from Washington to California lost billions in value due to wildfires

Lightning identified as the leading cause of wildfires in boreal forests, threatening carbon storage
Lightning is the dominant cause of wildfire ignition in boreal forests—areas of global importance for carbon storage—and will increase in frequency with climate change, according to new research......»»
Forests with multiple tree species are 70% more effective as carbon sinks than monoculture forests, study finds
To slow the effects of climate change, conserve biodiversity, and meet the sustainable development goals, replanting trees is vital. Restored forests store carbon within the forest's soil, shrubs, and trees. Mixed forests are especially effective at.....»»
Investigating banana trees as buffers to fight wildfires
Fire buffers composed of irrigated banana trees could slow and calm wildfires and generate profit for residents of fire-prone regions, according to a study published in PNAS Nexus. Climate change is increasing wildfire risk. Wildfires in the Western.....»»
