A team of natural resource specialists from the Chippewa National Forest (CNF) and regional scientists participated in a three-day workshop in July 2013 to develop the ASCC treatments for the site. The team developed a set of management objectives, desired future conditions, and silvicultural tactics for each adaptation option:
RESISTANCE
maintain relatively unchanged conditions over time
Management Goals:
- Life boat red pine into a drier future by increasing soil moisture availability during drought
- Maintain red pine dominance (90% basal area) while increasing soil moisture availability during drought
- Productivity remains high and disturbance remains low, but there may be variability within an acceptable range
- Reduce stocking closer to woodland structure
Strategies & Approaches:
- Uniform (free) thin (100 ft2/acre) removing red pine and jack pine to maintain species diversity
- Maintain red pine dominance
RESILIENCE
allow some change in current conditions, but encourage eventual return to original conditions
Management Goals:
- Red pine remains dominant (50-75% basal area)
- Increase heterogeneity and structural complexity
- Increase native future-adapted species
- Productivity remains high and disturbance remains low, but there may be variability within an acceptable range
Strategies & Approaches:
- Site preparation in gaps with harrow disk
- Variable density thin (20% in gaps, 20% in reserves, matrix thinned to 110 ft2/acre)
- Maintain red pine dominance
- Plant future-adapted native species in gaps (eastern white pine, jack pine, red oak, bur oak, and red maple)
TRANSITION
actively facilitate change to encourage adaptive responses
Management Goals:
- Reduce red pine dominance to 20 – 50%
- Increase future-adapted species
- Productivity and disturbance occur within slightly wider acceptable ranges
- Increase heterogeneity and structural complexity
Strategies & Approaches:
- Site preparation in gaps with harrow disk
- Irregular shelterwood (20% in gaps, thin matrix to 70 ft2/acre)
- Increase future-adapted species in gaps and matrix, including native and new species (eastern white pine, red oak, bur oak, white oak, red maple, bitternut hickory, black cherry, and ponderosa pine)
