Afire: Fire Ignition, Mitigation & Recovery
Forestcast
Fire shapes landscapes and lives, but how do humans shape fire? By measuring wildfire ignition, mitigation, and recovery, as well as the wildland-urban interface—where houses meet or intermingle with undeveloped wildland vegetation—scientists are uncovering the complex dynamics between wildfire and human behavior. Research social scientist, , sheds light on the rapidly growing wildland-urban interface and the challenges it poses for fire management and community resilience. Research forester, , delves into private landowners' behavior in central Oregon, and the surprising...

Afire: Fire Weather, Wind & Smoke
Forestcast
From whipping winds that fan flames to swirling smoke that obscures visibility, fire weather is a complex phenomenon. In Episode 4 of "Afire," hear from three meteorologists at the intersection of the intricate relationships between fire weather, wind, and smoke. explains how large-scale atmospheric patterns, like extended dry periods before a wildfire, may contribute to the development of extreme fire events. discusses WindNinja, a high-resolution wind model that simulates local winds in complex terrain. And investigates the turbulent dynamics of small‑scale surface fires, as...

Afire: Understanding Different Fire
Forestcast
Prescribed fire plays a vital role in creating healthy landscapes that better survive natural and human-caused disturbances, while reducing wildfire risk to communities, infrastructure, and natural and cultural resources. Episode 3 of "Afire" highlights three scientists and partnerships that are attempting to better understand and utilize prescribed fire. From Georgia, ecologist explains how researchers and forest managers are forming unique meetings that spark fresh ideas and advancements in prescribed burning across the South. In California, forester begins research into the processes...

Afire: Understanding Fire Differently
Forestcast
Indigenous tribes gained their unique understanding of fire, and the role of fire on the landscape, long before European settlers came to what is now called North America. Since then, the relationship between federal fire management and indigenous perspectives has often been one of misunderstanding and mistrust. On Episode 2 of "Afire," join Forest Service scientists, , a tribal descendant, and , a tribal member, as they explain the ways in which Forest Service fire research is collaborating with tribes to jointly strive to better understand and manage fire.

Afire: Understanding Fire
Forestcast
Fire is a form all of its own, but a simple way to understand fire is as a swarm. A swarm of bees. Or starlings. Or mosquitos. A spreading fire is a swarm of ignitions, a series of small fires over and over. Season 4 of Forestcast is a series of fires, a series of voices. It’s a 360-degree introduction to fire from a scientific standpoint. The story of how fire research shapes our landscapes, and our lives. Through kaleidoscoping voices from across the country, listeners will be taken inside the largest forest research organization in the world to hear from seventeen scientists on what...

Flying the Nuthatch Home
Forestcast
Once spanning nearly 6 million acres in Missouri's Ozarks, the shortleaf pine and oak woodland ecosystem has dwindled to 100,000 acres today. Along with the loss of this habitat, a bird—the brown-headed nuthatch—disappeared as well. However, after decades of woodland restoration, the brown-headed nuthatch has returned to Missouri—by plane. Over two summers in 2020 and 2021, a team of scientists successfully captured and flew 102 birds from Arkansas to Missouri, marking the bird’s return to the state after being locally extinct since 1907. Weighing in at a mere one-third of an ounce,...

Women of Research: Changing the World Through Soil with Deb Page-Dumroese
Forestcast
Research soil scientist research interests center around maintaining soil productivity during and after land management activities. As site principal investigator for several plots, Deb is well-versed in the pre- and post-treatment sampling necessary to determine changes in above- and below-ground nutrient properties associated with harvesting, organic matter removal, and biochar additions. In partnership with the Missoula Technology Development Center (Keith Windell) and Dr. Nate Anderson (RMRS) she developed a to easily distribute biochar on forest sites. Related Research: (2022) ...
info_outlineWith no parasitic wasps — like we have for emerald ash borer — and no miracle fungal pathogen — as with gypsy moth — our control options for the nonnative insect threatening Eastern hemlock forests, the hemlock woolly adelgid, have been tricky. Hemlock forests, and the hemlocks in your yard, are paying the price.
