New models predict fewer lightning-caused ignitions but bigger wildfires by mid century

"...Scientists including Meg Krawchuk of the OSU College of Forestry and former OSU research associate Ana Barros, now of the Washington Department of Natural Resources, say the findings can help local decision-makers understand how a changing climate might affect natural and human-caused fire regimes differently and inform fire staffing, preparedness, prevention and restrictions..."

Smoke Seasons

"...If the events of 1950 shows us that boundary-crossing global-scale smoke is not in itself new, the frequency and intensity of our twenty-first century fire regimes are the product of escalating climatic change. In the twenty-first century, the scale of wildfire and transient wildfire smoke has disoriented and alarmed many of us. The media calls the faded orange sun, midday darkness, and air quality warnings unprecedented, apocalyptic, and an omen of a troubled future..."

Climate change and fire suppression

"..."We wanted to know how climate change and fire suppression, each in different ways, can influence fire regimes," said coauthor Naomi Tague, a professor of ecohydrology and ecoinformatics at UCSB's Bren School of Environmental Science & Management..."

Climate change and suppression tactics are critical factors increasing fires

"...Hanan is a researcher with the University's Experiment Station and Assistant Professor of Natural Resources & Environmental Science in the College of Agriculture, Biotechnology & Natural Resources. She and her collaborators at UC Merced, UC Santa Barbara, Washington State University and the University of Washington, Tacoma, used a novel modeling approach to examine how climate change and fire suppression influence fire regimes across watersheds..."

How soil fungi respond to wildfire

"..."There has been renewed interest in how climate change is influencing the frequency of fires and how that's going to affect fire-mediated ecological processes in California going forward," said Peay, who is senior author of the research. "So it's important to have specific details about how changes in the fire regimes in California, and the West Coast in general, are going to be influencing ecosystems. "..."

Megafire does not deter Yosemite's spotted owls

"..."In Yosemite there is a diversity of forest habitat" explains Schofield, "This means the Rim Fire burned with a diversity of severities creating a range of post-fire habitat for owls to choose from. " The study notes that in portions of the adjacent Stanislaus National Forest that were also burned by the Rim Fire, burn severity was more homogenous likely due to the contrasting logging and fire management regime on the National Forest..."

Herbivores, not predators, most at risk of extinction

"...Already the consequences of declines in modern herbivores from land-use change and hunting have begun to echo those that occurred on Earth 1 million years ago; alterations to plant life, changes to fire regimes, and disruptions to nutrient cycling. This study highlights that we must redouble our efforts to strategically invest in conservation and management of herbivores to avoid future dramatic changes in the functions arising from animals at the base of global foodwebs. Although the results of the study indicate that herbivores are the most at-risk group, it is not clear sailing for predators..."
