Mast Reforestation

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.

We’re scaling a new model: carbon removal through biomass burial that funds reforestation.

We are rebuilding the systems needed to recover what’s been lost, and scaling them to meet the moment.

Thank you to everyone who attended Mast’s SF Climate Week event at the SF Melody last week!

We encourage each of you to keep the urgency alive in your daily pursuits for the climate.

Hoping to catch you at the next one—looking at you, #PNWCW25.

Our first biomass burial project, MT1, is now live on Puro.earth's listings!

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.

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.

Instead, we're burying it to store carbon, reduce fire risk, and generate CDR credits.

@trellisgroup.bsky.social takes a closer look at how our biomass burial projects generate carbon credits while restoring forests.

From field prep to replanting, here’s how it works: trellis.net/article/mast...

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: www.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.

How a CAL FIRE Grant is Expanding Our Seed Processing Capacity at Cal Forest 47,500 conifer seedlings have been planted to restore Feather River Dome's iconic forests in Butte County, CA lost to the 2020 Bear Fire.

With @calfire.bsky.social's Business Workforce Development Grant, we processed 100M seeds in 2024—scaling reforestation for 300k+ acres of fire-impacted land.

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: www.mastreforest.com/insights/bio...

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

Wildfires are burning forests faster than we can regrow them. Restoring 24M acres in the West needs 2.2M lbs of seeds.

Why bury burned trees?

Leftover biomass fuels future fires. Burying it locks in carbon, funds reforestation, and helps new forests thrive. Carbon purchases makes all of this happen.

We recently announced big news for carbon removal & reforestation 🗞️🌲

We’re humbled to have the support of such incredible investors as we take a major step forward with our biomass burial project.

We’re just getting started. Learn more about our journey: www.mastreforest.com/insights/bio...
