Minnesota Wildfires: Crews Hold Brimson Complex Fires Perimeter, Fight Against Wildfires Continue
- Last year, the spruce budworm outbreak affected about 712,000 acres in Minnesota's Arrowhead region, the largest since 1961.
- The outbreak results from the budworms exhausting their food source and moving to adjacent areas, with such outbreaks lasting six to ten years.
- Balsam fir, favored by the budworm and abundant due to fire suppression and past outbreaks, contributes to fire spread through its flammable needles and resinous bark.
- Chris Dunham said planting 2.5 million trees this year in northern Minnesota aims to increase species diversity, as "diversity is the superpower of the forest."
- Sustained monitoring and maintenance over seven to ten years are required to ensure these plantings survive and reduce forest vulnerability to budworm and fire.
