Treatment: maintain relatively unchanged conditions over time

Management Goals

People walking through the driftless area ASCC Site in a lush green area.
Allowing forest to remain oak dominated will keep the Resistance plot conditions relatively unchanged over time.

  • Maintain northern red oak and white oak > 50% BA
  • Stocking maintained around 70%
  • Increase size and quality of overstory trees
  • Maintain sparse and native midstory, allowing for advance regeneration of oak and hickory species
  • Reduce prevalence of invasive species

Strategies & approaches

  • Invasive shrub treatment (honeysuckle, buckthorn, garlic mustard)
  • Midstory removal
  • Free thinning (~70% stocking)
      • Prioritize species as follows: white oak, other oak species (mainly northern red oak), and black walnut
  • Repeat thinning in future years; maintain full stocking ~65-70%
