Very old fire-scarred stump. The astute observer will notice two whitetail deer in the background. 🔥

Rampant #wildfires in #Alberta have now forced several communities to evacuate. Our research sites remain unaffected, however, we know how quickly things can change and how dangerous it is for the crews. #firescarfriday 🔥Be safe out there, friends.

I saw some cool fire-scarred trees, snags, and stumps on my mtn bike ride today.
Those two snags have 6+ fire scars each. 🔥

From the central cascades in WA, here’s my #FireScarFriday, a beautiful example of fire suppression. I’m holding the outermost curl in my hand, and pointing to earlier scars that are just a few years apart! It also appears to be a CMT with old cut marks along the face. A beauty!

Fire-scarred western red cedar trees as seen while biking (on a Friday) in #GlacierNationalPark two weeks ago.
Plus a bad picture of a mama black bear with cubs!

Why do fire scars form more on the leeward or uphill sides of trees? For #firescarfriday here's a little time lapse video showing the increased residence time of flame, and thus increased heating and potential cambial injury, in the eddy of air in the lee of this long leaf pine. Florida, USA, 2025.

For #FireScarFriday is a sample from WA state. A unique remnant with approx 12 scars! I added in red lines so you can see where the scars are. This piece was sawed off the top of a stump that was cut long ago. I love how the scars and pith were preserved but not much else haha! 🌲🔥❤️

See this little guy? This little guy has five visible fire scars!
As observed in the Mica Mountain Wilderness, Saguaro NP, Arizona.

#firescarfriday Here's Chris Baisan from Tree-Ring Lab in Tucson sampling a giant sequoia stump with several "eye socket" fire-scar catfaces. Record was 80+ fire scars in one of these; ground level in the past was higher, hence the whole socket begin visible.

Flaming fire scars at the base of a longleaf pine (Pinus palustris) in the Red Hills of Florida USA. 04/02/25. Interesting how intensely these can burn once they get going. #firescarfriday

My last #FireScarFriday post ignited a fruitful debate around 🔥-scarred redwoods and sequoias being culturally modified by certain Tribes to create sacred spaces, an alternative hypothesis to their "natural" formation. Here is the "Four Directions" tree considered sacred by the Esselen Tribe.🌎🌲🍁🔥🌳🪶

IMO this sequoia was intentionally fire-scarred (culturally modified) by the Native Peoples to create a ceremonial space inside the tree, as well as to induce flaring of the base to enhance the tree's size and longevity. Or is this simply a "natural" occurrence? Your thoughts? #FireScarFriday 🌎🌲🍁🔥🌳🪶

A throwback #FireScarFriday to this special catface I visited last fall in the redwoods. It had a short informational trail with some cool diagrams of tree rings and scar evidence. Science in the woods is 🔥🔥🔥

🔥🌴 In Oct 2024, I observed the 75+ palm trees that burned during the Sep 28, 2022 lightning-caused wildfire in Agua Caliente Park (Tucson, AZ). The park has done a great job with restoration in those two years since the fire.
Check out the interesting burn patterns on the trees. #FireScarFriday
