The OSU Research Forests will begin slash pile burning on the McDonald and Dunn Forests soon.

Select 'slash', tree branches, tops, and unmerchantable portions of tree stems, have been gathered into piles for burning. Some slash and coarse woody debris are also scattered throughout the harvest area for retention.

Pile ignition occurs during the fall and winter rainy seasons – typically October through January. The work happens during specific weather windows to reduce smoke intrusions into neighborhoods. The Research Forests perform this work with local fire and smoke managers' approval.

Piles typically burn down to the ground in one day, but some piles may smolder for days to a few weeks. Research Forests staff will monitor the progress of this prescribed burning.

Slash pile burning is a cost-effective way to perform wildfire hazard mitigation, reduce fuel-loading, and prepare sites for tree planting.
