Some Success In Pine Forests With Managed Wildfires

By Melissa Sevigny
The U.S. Forest Service allowed fire to burn more than 73,500 acres in northern Arizona last year. New research examines how well these “managed wildfires” restore healthy, historical conditions to ponderosa pine forests.

Scientists with Northern Arizona University’s Ecological Restoration Institute examined 10 large burned areas on the Coconino and Kaibab national forests. Ecologist David Huffman said managers allowed these areas to burn during the last decade to meet multiple restoration goals.

“Wildfire is difficult to control and manage for precise effects — sort of a blunt tool,” he said. “So we need to understand what it’s doing out there in terms of changing forest structure.”

The study found moderate-severity fires met two-thirds of the restoration goals. This was the only type of fire that restored tree density and canopy cover to historical conditions.
