Using fire to increase the scale and benefits of forest fuel treatments: Research Brief
/This brief discussed a 2012 study that indicates less than 20% of national forest and national park lands in the Sierra Nevada are experiencing fuels treatments needed to mitigate continuing degradation from either the lack of fire or wildfire burning at high severity.
Read MoreUsing Fire for Invasive Plant Control in Wildlands: USGS Research Brief
/This brief summarizes the current state of knowledge on the use of fire as a tool to manage invasive plants in wildlands. The authors of two publications discuss risks and challenges of conducting prescribed burns, types of systems and circumstances in which burning may be effective for the management of invasive plants, complexities of fire and plant community interactions, impacts of prescribed burning on the broader plant community and the soil, and comprehensive monitoring plans.
