A short clip of the 2025 Dillon wildfire in northern California. We (the USFS Fire Behavior Assessment Team) took immediate pre-, active-, and post-fire measurements of this and other forests to understand how fire behavior shapes forest health.

Great visualization of the 'dripline' on trees. Fallen needles accumulate just under this tree in the golden trout wilderness.

Arborglyphs are fascinating, complex, and controversial. I always feel terrible for the tree and the damage it has suffered! However, this is something quite cool with finding one like this one - in southern Utah.

Despite my past trauma with bark beetles 🐞, I still find their galleries beautiful (so long as they are not in my ear)!

Meet Ol' Blue - the world's oldest blue spruce. Seen here getting a hug on its 457th birthday. We made it a cake, gave it a party hat, and sang it a song.

Tree rings a beautiful! This is an image of a Great Basin bristlecone pine (Pinus longaeva) core with the years 1999 - 2017 visible (oldest on the left). The four pencil dots mark the year 2000 and the paired dots mark a missing ring (2002) which was extremely dry at this site.

Sometimes I wish I was a cat so I could snuggle under a blanket and forget about things for a while...

Biodiversity is all around us if we know how/where to look!
