OREGON — Roughly two years after the devastating blaze, recovery efforts from the Holiday Farm Fire continue in the McKenzie River Corridor. …Salvage efforts since fall of 2020 have found many trees that have suffered extensive damage, enough that many aren’t usable for much. But leaving these around — along with other debris — creates fuel for future wildfires.But nearby, workers are also operating an open metal chamber that’s taking all that slash, and incinerating it. Jonas Parker, a district hydrologist and soil scientist with the Bureau of Land Management, explained to KLCC how the air current burner — in this case, a CharBoss — works. …Through integrating biochar into the affected areas, the soil can be enriched and also made less apt to let water flow away. And the CharBoss contains a lot of the burning matter within its chamber, which means less smoke released into the air.
