200 Dead Giant Sequoias in Alder Creek Grove California

Alder Creek Grove Sequoia Mortality Map

It took several months, but I finally managed to count every mature giant sequoia in the Alder Creek Grove. My original goal was to document all the dead sequoias. I went through the grove top to bottom thoroughly to capture their locations. I also added those that were heavily damaged since I thought it was important. Then, while looking at the map I thought, I really need to add the living sequoias for context. And to make it look less bleak! So, I started by adding points I already had on my personal map, and then went out and started filling in the remaining trees. With gracious assistance from my partner Kim Dicso who went traipsing around the forest while my knee was out of commission, the map is complete.

And I’m making it public. I’m reaching out to readers to help raise awareness about what happened to these ancient trees. The SQF Complex / Castle Fire destroyed thousands of giant sequoias across multiple groves. The impact on these rare old giants is immense. The sequoias thrive on lush, cool mountain slopes, but we are quickly turning these landscapes into dead snag forests or scrub desert where conifers no longer grow. Please support efforts to reign in climate change so we can once again see increased snowpack and a less hot and dry world. Start by reading David Attenborough’s A Life on Our Planet.

Black points (dead sequoia at least 6ft DBH): 200
Gray points (heavily damaged sequoia – lost top/nearly full brown needles/unsure if living or not): 49
Green points (alive – moderately damaged/lightly damaged/unchanged): 278

NOTES:

  • Only sequoias at least 6ft DBH (estimated) were included. Hundreds of smaller dead sequoias are not included.
  • Sequoias continue to die post-fire. Points may not be updated to reflect these losses.
  • Moderate or light sequoia damage was not recorded.
  • Photos prior to the fire are often included (some before and after shots also included).
  • Two smaller sequoias were added due to the importance of their locations. One is a living but heat scorched sequoia to the far west (closest to the outlier). One is at the south end with nearly all brown needles.
