Their most notable supported claim

Assertion Supported
Canary says Mast buried ten million pounds of fire-killed trees in Montana

Canary says Mast Reforestation buries dead trees to generate carbon credits
“So, we are taking fire-killed trees. So, these are trees that have been impacted by the bad fire, not the good fire. They're totally dead. They're a fuel risk. And they're, wow, there's a lot of acres of them. We're burying them, and that stores the carbon tha…”

Disclosure
Canary says Mast abandoned drone seeding due to seed constraints and inconsistency
“Seed constraint was such a hard constraint, and we'd spent two to three years also with the seed vessel, and like, really dialing that into the Have less variability and more consistency was going to be a challenge and so having spent a number of years on the …”

Assertion Not checkable as stated
Canary says subterranean sensors show biomass decomposition emissions far below modeled levels
“We're monitoring for methane and CO₂ The data that's been coming back over the last year is fantastic. We're way below what we modeled. Definitely way below what is allowed. So, like, we are not seeing that decomposition.”

Assertion Supported
Canary says high-severity fires increasingly trap forests in brush states
“What we're seeing is that we are seeing not only more and more high-severity fires where forests don't come back, they end up in a persistent early seral phase, which is nice fancy words for, like, ten-foot-tall brush for, like, the next, you know, decades, if…”

Canary calls combining hardware, biology, and software a startup double black diamond
“From a VC perspective, you're like now combining hardware with biology, With software, like talk about like the double black diamond of a startup, like that's really difficult.”

Insight
Canary says aerial drone seeding consumes far more seed than hand planting
“And for a drone company operating, and we're going to be more consumptive of seed than taking seed, planting it in trays to be in a nursery, and then growing it into seedling hand planting, far less consumptive of seed.”
Grant Canary Sep 9, 2026 ▶ 18:54 Burying trees to save forests?
Insight
Canary says carbon credits massively revalue legacy commodity forestry seed assets
“Because of what I just described about mass events and the difficulty in collection, and the, it was highly undervalued because things are, in the forestry space, are a commodity, and being able to take and apply that resource with the seed zones and then bein…”

Disclosure
Canary says Mast faced severe difficulty selling subsequent ex-ante carbon credits
“We sold out our first project with what are called anti-credits, or credits that take carbon in the and how much carbon they will capture in the future into account and then our subsequent projects what was the buyer feedback? What's the customer feedback? Lik…”

Assertion Partly supported
Canary says Mast sold out carbon credits to major buyers in days
“And then the credits that we generated, like, we sold out within two days of issuance of credits. Took us a couple weeks to, like, paper the contracts. But our buyers are Bain. Bain Consulting, not known for being tree-loving hippies. Like, very aggressive and…”

Opinion
Canary says buyers reject biomass carbon credits if wood has alternative uses
“Even if I wanted to, like, we wouldn't have the customer adoption to pay for those credits if it could have gone to a mill or it could have gone to an energy facility or something along those lines.”

Canary says burnt conifer forests can hold 80 to 300 dry logs per acre
“You might have 80 to 300 old logs per acre in a burnt out conifer forest, and after a couple years of undergrowth whether it's invasives or natives, like, they get super dried out, you get a lightning strike, boom, you got the next wildfire again”

Assertion Supported
Canary: Conifer mast events can happen as infrequently as once or twice a decade
“A mast event can happen as infrequently as once or twice a decade, and it's not, like, the whole species of, like, dug fur across the West Coast, like, all goes at once in a mast event.”

Assertion Not yet assessed · timeframe Sep 2027
Canary says removing fire-killed trees is post-fire reforestation's largest cost
“So that was we exited there, but the natural fit there is when we were doing these projects, the number one cost, because these projects were post-fire, was removing the top cost was removing the fire-killed trees.”
