Jack pine (Pinus banksiana Lamb.) is a common tree species in central and eastern Canada, and the northeast and north central United States. Common silvicultural practice for jack pine is a cutting regime of 40-70 years, followed by natural regeneration with or without supplemental planting. Jack pine is a fire- adapted species, where fire opens serotinous cones and produces a mineral soil seedbed. The effects of mechanical treatment (anchor chaining) and prescribed burning, alone and in combination, on jack pine forest biodiversity and regeneration, were determined on the Baraga Plains of Michigan’s Upper Peninsula. We assumed that both treatments would facilitate natural jack pine regeneration through scarification, in what is currently a clearcut. In order to assess the implications of landscape scale implementation, we determined the effects of the treatments on understory vegetation. In addition, the diversity of ground dwelling arthropods was determined by pitfall trapping. The main treatment goal was to enhance regeneration such that the density of seedlings, if produced on a landscape scale, will be suitable for the establishment of a breeding population of the endangered Kirtland’s warbler (Dendroica kirtlandii).
