Treatment: allow some change in current conditions, but encourage eventual return to reference conditions
Management Goals
Multi-cohort stand with greater structural complexity, larger trees, and maintained or increased quality
Favor native mast-producers that are drought, fire, frost, disease, and wind tolerant
Increase genetic diversity of tree community
Maintain spare and native midstory, allowing for advance regeneration of oak and hickory species
Provide hard and soft mast for wildlife
Reduce prevalence of invasive species
In the Resilience treatment the team will focus on increasing heterogeneity and structural complexity in the Driftless Area ASCC site. Photo Credit: Courtney Peterson, Colorado State University.

Invasive shrub treatment
Midstory removal
Site preparation including prescribed fire if conditions allow
Underplant intermediate, shade-tolerant, fire-adapted native species
Continuous cover irregular shelterwood: first and subsequent establishment cuttings will create three 0.75-acre opening and three 0.75-acre patches 40-50% cover
Free thinning matrix to ~70% stocking
Retain some dominants as seed trees, plant additional seedlings (chinkapin oak, white oak, northern red oak, black walnut, bur oak, shagbark hickory, black oak, black cherry)
Miranda Curzon (Iowa State University) is the site lead for the Driftless Area. Key partners include Bruce Blair and Jeff Goerndt (Iowa Department of Natural Resources), Brad Hutnik and Greg Edge (Wisconsin Division of Forestry), and Mike Reinikainen and Paul Dubuque (Minnesota Department of Natural Resources).
