Beyond the burn: Harvesting dead wood to reduce wildfires and store carbon
2025-02-26
A century of fire suppression, combined with global warming and drought, has led to increasingly destructive wildfires in the Western United States. Forest managers use tools like prescribed burns, thinning, mastication, and piling and burning to reduce fuel – live and dead trees, needles and leaves, and downed branches – that can feed intense wildfires. These methods aim to lower fuel levels, reduce crown density, and protect fire-resistant trees, fostering healthier, more resilient forests.
However, prescribed burning efforts haven’t kept up with the rapid buildup of surface fuel, creating a “fire deficit” – the gap between the amount of fuel that has ...
