1. Site preparation: Harvesting, partial harvest with residual maple
overstory, full tree skidding (Aspen/birch stand, MN)

Quaking aspen stand (MN)

3. Conditions following harvest operation that are scheduled for prescribed
burning

4. Prescribed burning by drip torches

versus unharvested patch. Aspen/birch harvested and maples
were left as residuals (MN)

6. Prescribed burning that burned too hot, damaging soil (OR)
Not commonly used anymore
