Our op-ed in the Santa Fe New Mexican today highlights the potential losses from closure of the nine US Forest Service Regional Offices, namely local leadership knowledge and capacity, experienced people, and priceless documentary records: www.santafenewmexican.com/opinion/my_v...
The legacy lost when Forest Service offices shut down
After 117 years of operation, the U.S. Forest Service’s Southwest Regional Office in Albuquerque is closing by order of the secretary of agriculture. Since 1908, this office has directed the

Intensifying Fire Season Aridity Portends Ongoing Expansion of Severe Wildfire in Western US Forests
Area burned by wildfire has increased in western US forests over recent decades. However, high-severity fire—fire that kills all or most trees—is also an important metric of fire activity given its d...

Good article, but wildfire is never “preventable”; all of the management strategies outlined will never stop wildfire from burning at some point, but will “mitigate” severe effects and damage to human infrastructure. But fire itself is inevitable in these ecosystems; best accept that fact.
The dramatic images from wildfires tearing through Spain and Portugal year after year have become a mainstay of Europe’s increasingly blistering summers.
But experts say that most of the damage is, in fact, preventable — if only authorities at regional, national and European levels would act.

Wildfires are preventable. So why does the Iberian Peninsula keep burning?
Governments can’t use climate change as an excuse for failing to take preventive measures, scientists say.

The Turkeyfeather Fire in the Gila Wilderness, NM has burned as a low-severity fire over about 24,000 acres (so far). This is a continuation of a fire regime that existed for millennia before the 20th century. This 🧵reviews the fire history of the Gila, as my colleagues and I have studied it. 1/18

Such a neat story!
Fun bit of geochronology detective work, hypothesizing that the Meteor Crater Impact (Arizona) caused a landslide and paleolake formation in the Grand Canyon, and it all started with the discovery of driftwood in Stanton’s Cave in the 1980s pubs.geoscienceworld.org/gsa/geology/...
