Challenges for Forest Adaptation
1) Uncertainty of future conditions
2) Scale of science ≠ Scale of management
3) No single, one-size-fits-all “answer”
4) Lack of real-world examples*

1. DEFINE area of interest, management
objectives, and time frames.
2. ASSESS climate change impacts and
vulnerabilities for the area of interest.
3. EVALUATE management objectives given projected impacts
and vulnerabilities.
4. IDENTIFY and implement adaptation
approaches and tactics .
5. MONITOR and evaluate effectiveness
of implemented actions.

Adaptation Demonstrations
• Provide real-world examples of forest management activities that: • Enhance the ability of forests to cope with changing
conditions • Achieve land owner management goals
• Foster cross-ownership dialogue and learning

Short Example:
Upland Hardwoods at Caroline Lake Preserve
© Scott Mulcahy
![Page 17: Silviculture in the 21st Century](https://reader031.vdocuments.mx/reader031/viewer/2022012413/616d85876ff1463c4328a530/html5/thumbnails/17.jpg)
Upland Hardwoods Management Goals & Objectives: • Maintain/restore forests that were historically characteristic • Mid-to-late successional forests
• Natural disturbances • Under-represented species
Climate Change Challenges: • Warmer temps, altered
precipitation, drier summers • Projected declines in many
common northern species
![Page 18: Silviculture in the 21st Century](https://reader031.vdocuments.mx/reader031/viewer/2022012413/616d85876ff1463c4328a530/html5/thumbnails/18.jpg)
Upland Hardwoods Actions already being done (current mgmt.)
Practice Current Purpose Adaptation Benefits
Favor under-represented species
Species/structural diversity; habitats
Hedge against decline of one species; opportunity to favor future-adapted species
Encourage large woody debris
Structural diversity; habitats; nutrients
Create moister and cooler conditions on forest floor
Mimic natural disturbances
Species/structural diversity; accelerate succession
Makes it easier to take advantage of natural disturbances
![Page 19: Silviculture in the 21st Century](https://reader031.vdocuments.mx/reader031/viewer/2022012413/616d85876ff1463c4328a530/html5/thumbnails/19.jpg)
Upland Hardwoods Easiest • Plantings to increase the component of local, native
species that are expected to fare better under warmer and drier conditions (red oak, white pine).
• Conversion of mixed stands containing advance red oak regeneration into oak stands.
More Difficult • Identify areas to potentially serve as refugia (difficult to maintain in long-term) • Introduce species from outside of the area that might be better adapted to future conditions (bur oak, white oak, …)
![Page 20: Silviculture in the 21st Century](https://reader031.vdocuments.mx/reader031/viewer/2022012413/616d85876ff1463c4328a530/html5/thumbnails/20.jpg)
Summary • Uncertainty is guaranteed.
Management will be most effective if it works with uncertainty, rather than against it.
• There is not a shiny new tool for coping with climate change. Rather, we have the same old tools but will need to use them in new ways.
