Predicting Fire Behavior with New 3D Fuel Models

Land managers have a new tool in their firefighting arsenals that models forest fuels in three dimensions. These 3D fuel models developed by the USDA Forest Service have the potential to make firefighting and the management of controlled burns safer and less costly while helping to protect valuable natural resources. The 3D fuels modeling technique…  More 

Weather Conditions Inform Timing of Prescribed Fire

Prescribed fires generate smoke, which can harm human health – especially in areas where humans and forests are close together. “Weather conditions are critical for prescribed fire, especially the effects of wind and humidity on smoke plume formation,” says Yongqiang Liu, USDA Forest Service research meteorologist. Liu is the lead author of a modeling study…  More 

How Much Smoke Will a Prescribed Fire Produce?

Prescribed fire is an important and widely used management tool, but the smoke produced can cause air quality issues and health problems. Before conducting prescribed fires, managers typically model the amount of smoke a fire will produce, which is directly related to the amount of fuel available. “Most fire-effects models were developed in the western…  More 

In the Southeast, Who’s in the Path of Smoke Plumes?

For more than 30 years, researchers have known that poor communities and people of color in the U.S. are more likely to be affected by environmental threats such as landfills and toxic waste sites. “Are these socially vulnerable communities also exposed to more smoke from wildfires and prescribed fires?” says U.S. Forest Service scientist Cassandra…  More 

Climate Change and Wildfire

Concerns continue to grow about the effects of climate change on fire. Wildfires are expected to increase 50 percent across the United States under a changing climate, over 100 percent in areas of the West by 2050 as projected by some studies. Of equal concern to scientists and policymakers alike are the atmospheric effects of…  More
