Foresters call these “cookies”. We bake them to measure dry mass, a key step in calculating carbon for removal. Accuracy here helps fund reforestation where it’s needed most. Learn why we’re burying dead trees to fund reforestation: mastreforest.com/insights/bi…

Our first biomass burial project, MT1, is now live on @PuroCO2Removal! We’re breaking ground in Montana, burying fire-killed trees from the 2021 Poverty Flats Fire to permanently remove carbon and fund post-wildfire reforestation. Learn more🔗shorturl.at/KLSFf

2.3M tons of fire-killed trees have nowhere to go—too damaged, too far away from facilities that may take it, or simply too much. Landowners typically burn what can’t be sold. We're burying it to store carbon, reduce fire risk, & generate CDR credits. 🔗mastreforest.com/biomass

The U.S. is falling behind on reforesting burned land—by 3.8M acres. That gap could triple by 2050. Here's what it’ll take to close it: frontiersin.org/articles/10.…

Scouting new biomass burial sites, where fire-killed trees become carbon sinks instead of going up in smoke. Each site brings us brings us closer to scaling this solution, reducing wildfire risk, and making reforestation and ecological recovery possible. Plenty more to come!

We bury fire-killed trees to lock away carbon and make reforestation possible. Novel? Yes. Straightforward? Yes. Immediate climate impact? Yes.

Wildfires leave behind killed trees that are costly to remove, but risky to leave in place. Our solution: Bury them to lock away carbon, reduce fire risk, and finance reforestation: mastreforest.com/insights/bi…

Mast MT1 will generate ~30,000 tonnes of carbon removal credits while funding reforestation— a market-first BiCRS pathway. v2026 credits now available. Let’s talk: carbon@mastreforest.com More here: mastreforest.com/insights/bi…

Wildfires are burning forests faster than we can regrow them. Restoring 24M acres in the West needs 2.2M lbs of seeds. Learn about it: mastreforest.com/insights/pr…

The hoedad, a common tool in any forester’s toolkit, is used to plant bare-root trees and aid in fire suppression. It’s part of our work at our Sheep Creek reforestation project in Montana. Learn how you can help restore our Western forests: mastreforest.com/projects/sh…

Post-wildfire site prep is costly. Charred trees fuel future fires and burning them releases carbon. We're burying burned trees to lock away that carbon: mastreforest.com/insights/bi…

Extreme wildfires are driving the seed shortage. The U.S. needs 1.3B seedlings yearly to restore forests—That’s like every person in the U.S. planting 4 trees, today. We’re scaling this to meet demand: mastreforest.com/insights/pr…
