Thank you to Placer PBA for a great burn today. We were working in 8 inch deep masticated brush. But letting the fire back down to hill kept it low. And with rains 3 days ago, we had minimal soil impacts and made biochar, which hold nutrients and sequester carbon. Plus a shaded fuel break for colfax
Thanks to the El Dorado Amador PBA and the American River Conservancy for a great burn today. Hopefully, we helped killed off the seed bank of invasive star thistle.
A chart of soil temperatures at different depths. As the fire peaked at 600C(blue). 6 cm into the mineral soil temperatures reached 60C
Want to see something surprising! As a 600C/1112F fire ate through the forest floor litter up top. Just 6cm/2.5in down into the mineral soil, the temperature only reached 60C/140F, cool enough for microbes and seeds to survive fairly well. Only 10-15% of fires energy is transferred down.
Also if you want to scratch your fire itch, I suggest you find your local prescribed burn association. Since they are formed from local community members, they are more chill all around.
I'm sorry for the hate you received, some of the responses in that post were awful. Wildland fire is filled with young men full of Machismo from rural areas. Being different is hard, but not impossible. The Life with fire podcast ep 32 & 33 have stories from trans women working in fire.
With the government shutdown coming up, it is likely access to pubmed and treesearch will go down. If only there was a site that allowed unrestricted access to scientific papers.
Surveyed a 10 year old burn scar yesterday. I've never seen so many acres of bitter cherry and goose berry before. There was bear scat everywhere.
I love it when a crazy contraption comes together. Hopefully, this allows me to simulate soil burn severity in a controlled manner.
The difference a fire makes. The first is a two year old prescribed burn up in French Meadows. The second is looking the opposite direction across the control line 10ft away. Not only is it beautiful, but is amazing insect and deer habitat.
