Abstract

An alternative to burning is needed for clearcut peatlands where only slash disposal is required to rapidly reproduce black spruce. A 2-year trial in north-central Minnesota indicates that reproduction will be rapid after full-tree skidding on nonbrushy sites taht have well-distribted sphagnum seedbeds and ample natural seeding. Broadcast burning is still recommended for most other conditions. The overall cost of slash disposal should be less by skidding than by burning if most trees are merchantable.
