Today we visited our research site in a CALFIRE demonstration forest, where the forest has been actively managed for uneven aged structure. See below, site of a successful prescribed burn done in June!

The first time I did field work in Big Basin was 14 years ago. I haven’t had any projects there since 2019, and then in 2020 the forest burned at high severity in the CZU fire. Today as part of a new project on management, fire, and carbon in redwood forests, I got to see big basin post-fire.

Hi bluesky, have any of my followers published in the journal Remote Sensing in Ecology and Conservation, and willing to comment on the experience (timely, reasonable, constructive?) My group is considering submitting there for the first time and I’m interested in others’ experiences there. Thanks!

Our research team just published a new paper: "Aspen impedes wildland fire spread in southwestern United States landscapes".

Aspen forests are thought to be more resistant to burning compared to conifer forests, but this has not been well studied.

Aspen (Populus tremuloides) forests are generally thought to impede fire spread, yet the extent of this effect is not well quantified in relation to other vegetation types. We examined the influence ...

There are 6 Forest Service research stations that also manage research labs, 80 experimental forests, a forest product laboratory, & the International Institute of Tropical Forestry. This is the most extensive natural resource research operation in the world--a hidden crown jewel of our country. 2/

So grateful for the amazing members of the Francis lab, @colinmast.bsky.social @lilianvallet.bsky.social, Ashley Zwick and Subham Banerjee (not pictured here)! So much creativity, quantitative thinking, and geospatial fire science data wizardry. Working with these folks is the best.

Our team just published a new paper in Global Change Biology 🧪🔥

The title succinctly describes the main take home message, but here's the deal:

4/4 Fir engraver and western pine beetle are less well-studied than other bark beetles such as mountain pine beetle or spruce beetle, but have caused substantial tree mortality in drought-affected forests in the last decade. Our results call for more attention on fir engraver and western pine beetle

Emily J. Francis @emilyjfrancis.bsky.social · Feb 11

3/4 A key result was the finding that large areas of forest in the western US are potentially at risk of tree mortality by fir engraver and, to a lesser extent, western pine beetle.

I'll end here with our conceptual model showing that a) fires were historically more prevalent yet served as a stabilizing feedback to ecosystems and humans by reducing fuel loads and risk of higher severity wildfires and b) contemporary fires are now destabilizing to forests and people.
