Wildfires are not always purely destructive. In many forests, fire can clear out built up dead material, return nutrients to the soil, and help ecosystems reset. For more than 100 years, the United States has spent billions of dollars on fire suppression to protect people, homes, and sensitive environments. But putting out too many fires can also prevent landscapes from getting the burns they need, allowing extra fuel to accumulate and raising the risk of larger fires later. New research … reports that nearly 38 million hectares of land in the western United States are historically behind on burning. The researchers describe these areas as being in a “fire deficit.” …”Conditions are getting so warm and dry that it’s causing huge amounts of fire compared to the historical record,” said Winslow Hansen, director of the Western Fire and Forest Resilience Collaborative and scientist at Cary Institute of Ecosystem Studies.
