    Studies by Isaac indicate that regeneration to Douglas-fir following logging often fails because a good seed crop is destroyed in the slash fire. To prevent this loss during a good seed year, early burning before seed fall starts has been recommended. If early burning is too hazardous, only the concentrations of slash should be burned later in the fall. In contrast, during poor seed years, a complete slash burn should be employed to keep the ground open for the next good seed crop. With favorable seedbed conditions and an ample seed supply, Isaac found that good stocking could be obtained on both burned and unburned surfaces.
