Climate Connections: Montana Ranch Buries Dead Trees to Lock Away Climate Pollution

Host: Dr. Anthony Leiserowitz
Guest: Grant Canary, CEO of Mass Reforestation
Date: March 27, 2026

Episode Overview

This episode focuses on an innovative approach to reducing climate pollution after devastating wildfires. Dr. Anthony Leiserowitz shares the story of Rebecca Gentry's Montana ranch, where traditional tree disposal methods are replaced by a new technique: burying dead trees to lock away carbon and prevent CO2 emissions.

Key Discussion Points and Insights

Aftermath of the Wildfire

• [00:01] Five years ago, Rebecca Gentry’s ranch in Montana was ravaged by wildfire, leaving behind “tens of thousands of dead scorched trees.”
• Common land management usually involves clearing dead trees and burning them to avoid dangers to people and animals, which unleashes CO2 stored in the trees.

The Carbon Impact of Traditional Practices

• Traditional burning of dead trees releases the CO2 those trees captured over decades, contributing to climate change.
  • Anthony Leiserowitz [00:19]:
    "But that releases the climate warming CO2 the trees absorbed as they grew,"

A Novel Solution: Subterranean Wood Vaults

• [00:36] Grant Canary of Mass Reforestation collaborated with Gentry to undertake a new approach:
  • Dug a 20-foot-deep pit, “buried millions of pounds of dead trees,” and capped the pit with fabric, gravel, and soil.
  • The surface is replanted with native grasses for cattle grazing, allowing continued agricultural use.
• Scientific backing: Burying wood deep underground slows decomposition, effectively trapping carbon.

Long-Term Climate Benefits

• Grant Canary [00:59]:
  "In the right conditions, the carbon is locked into the soil for hundreds, if not thousands of years, taking advantage of all the hard work that the trees did over decades to remove that carbon from the atmosphere."
• On-site monitoring will ensure the vault's effectiveness in sequestering carbon emissions over the long term.

Notable Quotes and Memorable Moments

• Canary [00:59]:
  “In the right conditions, the carbon is locked into the soil for hundreds, if not thousands of years…”
  —On the potential longevity of buried carbon and the innovative opportunity it presents.

Summary

In just ninety seconds, this episode spotlights how innovative land management—specifically, burying rather than burning dead trees—can help ranchers lock away climate pollution after wildfires. By sealing the carbon that trees have absorbed underground, rather than letting it escape back into the atmosphere, Mass Reforestation and forward-thinking ranchers like Rebecca Gentry are demonstrating a sustainable, climate-positive path for fire recovery.
