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.

Our newest study is out today! We found that 9 y after fire there were HUGE differences in bacterial and fungal communities between neighboring burned soils and small unburned refugia. Contact me directly if you can't access the paper and I will email you a pdf copy!

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.

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.

Our new paper is out on the dendroclimatology of Picea pungens (blue spruce) and Picea engelmannii (Engelmann spuce)! We describe the world's oldest blue spruce (Ol' Blue) and how each species responds to climate.
