The Bureau of Land Management is planning about a dozen prescribed burns in Wyoming this year in an effort to mitigate future fire risk.

Prescribed fires and mechanical thinning efforts are increasingly common land management tools intended to reduce the risk of catastrophic wildfire. But research into their long term effectiveness is somewhat limited. A recent study looked at the effects of such interventions over more than 20 years on a dry, low-elevation research forest in Montana, and found that the combination of thinning and burning was the most likely to reduce fire risk.

The Forest Service’s recently released “Strategy to Expand Prescribed Fire Training in the West” document is blunt: “The prescribed fire implementation environment continues to grow in complexity, IT READS, whereas the ability of practitioners to practice and hone their expertise has lagged, particularly in the Western United States.” The newly established Western Prescribed Fire Training Center is a major effort to address that workforce issue.

It made national headlines in October 2022 when Forest Service burn boss Ricky Snodgrass was arrested while overseeing a prescribed fire in rural Oregon. Now, a year and a half later, Snodgrass has been indicted on a misdemeanor reckless burning charge. The union he’s a member of is hopeful that he won’t be found guilty, but a representative says the case has still had impacts.

Prescribed fires can be an effective way to reduce the risk of severe wildfires. But they of course also give off smoke, and researchers are trying to better understand that public health tradeoff. A new paper finds that prescribed fire can reduce overall smoke exposure, but that those benefits can diminish as the level of prescribed fire increases.

A new paper analyzing the effectiveness of prescribed fire finds that they can substantially reduce the probability of high-intensity fires for as long as six years after the burn.

The Nature Conservancy has been working with prescribed fire for years, often with federal agencies like the U.S. Forest Service. Leaders say a new multiyear agreement with the USFS and other recent developments will help get more beneficial fire on the ground, and could serve as a model for expanding prescribed fire efforts across the region.

A new report from Headwaters Economics and Columbia University’s Climate School paints a damning picture of wildfire policy priorities: those interventions most effective at protecting communities and ecosystems – like building codes, home hardening and prescribed fire – often get the least support, while the least effective (and even sometimes counterproductive) – like wildfire suppression – receive billions in funding.

There are plans to spray herbicide aerially in the future, which has drawn both support and criticism. Herbicides, prescribed fire, and other methods are used each year to manage invasive species and sagebrush.

Scientists still aren't sure what maintains the Great Plains Grasslands and keeps them separate from forests. A very common hypothesis is that there are climatic differences between the areas where each type of ecosystem forms. But the boundaries between the two ecosystems have been slowly disintegrating since around 1850, which caused a U.S. Forest Service research ecologist to wonder if something else was responsible for keeping them separate.
