Mast Reforestation

The one-stop-shop for reforestation. We get projects up & running in months, not years, using proven practices & new-tech to regrow healthy, resilient forests.

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.

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 @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.

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.

@trellisgroup_ 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: https://t.co/xKrhY2Wv15

[Mast Reforestation @mastreforest]

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: https://t.co/QWKjV5p7ej

[Mast Reforestation @mastreforest]

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!

[Mast Reforestation @mastreforest]

We bury fire-killed trees to lock away carbon and make reforestation possible.

Novel? Yes.
Straightforward? Yes.
Immediate climate impact? Yes.

[Mast Reforestation @mastreforest]

With @CAL_FIRE’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: https://t.co/vdi6KIZqDe

[Mast Reforestation @mastreforest]

Mast MT1 will generate ~30,000 tonnes of carbon removal credits while funding reforestation— a market-first BiCRS pathway. v2026 credits now available.

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

We announced big news for carbon removal & reforestation 🗞️🌲

Humbled to have the support of incredible investors @TenzinSeldon_ , @pulsefundvc , @katelin_cruse , @sevensevensix and @chamath @socialcapital as we take a major step forward with our biomass burial project.

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.

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: https://t.co/vdi6KIZqDe

[Mast Reforestation @mastreforest]

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: https://t.co/2EqRc3aUyR

Wrapping up packout season at our nursery, Silvaseed.
We remove, sort, and store seedlings for the winter before shipping them to customers for reforestation projects. Place your seedling orders from now through 2026: https://t.co/Mf82WSSBlq

Transforming 160+ acres of burnt forest into a resilient ecosystem:

🌿 Site prep, 🌰 sourcing local seeds, 🌱 replanting native species, and 🌲 planting for the future.

A “mast event” is when conifers release massive amounts of seeds to regenerate forests. We’re collecting, storing, and planting to restore 24M acres: https://t.co/2EqRc3amJj
