Prescribed Fire Reduces Giant Sequoia Mortality by Over 50% in California Study

A University of Nevada, Reno study published on August 3, 2026 found that prescribed fire and fuel-reduction treatments cut tree mortality by more than half in the world's largest giant sequoia grove during the 2020 Castle Fire. The research demonstrates that restoring fire to these ecosystems—after nearly 200 years of fire suppression—can help protect these ancient trees from increasingly severe wildfires.

  • Prescribed fire reduced giant sequoia mortality by >50% during the 2020 Castle Fire at Mountain Home Demonstration State Forest
  • Study conducted at the world's largest giant sequoia grove in California's southern Sierra Nevada
  • Giant sequoias evolved with fire over millennia but faced suppression for ~200 years, leaving them vulnerable to modern severe wildfires
  • Research co-authored by University of Nevada, Reno forest ecologist Sarah Bisbing and colleagues

University of Idaho Mobilizes Wildfire Expertise Amid Western Fire Season

As wildfires spread across the western United States on August 3, 2026, the University of Idaho made available a range of expert researchers to discuss wildfire management, policy, community preparedness, and forest ecology. The university's Wildland Fire Center and affiliated researchers cover critical areas including fire-adapted communities, wildfire economics, and smoke impacts on human health.

  • University of Idaho hosts multiple experts in wildfire behavior, smoke health impacts, ecology, and community preparedness
  • Dennis Becker (dean of College of Natural Resources) available for discussion of wildfire policy and economics
  • Travis Paveglio directs the U of I Wildland Fire Center, focusing on community fire preparedness and fire-adapted communities
  • University resources address state and federal wildfire policy, suppression funding, and collaborative forest management
