Influence of climate change…
Common view: Climate change happens in the future
Better: Climate change is underway now

Influence of climate change…
Common view: Climate change will gradually make things warmer
Better: Climate change will be experienced as discrete events that interact with warming to impact management actions and options

Influence of climate change…
Common view: Effects of climate change are predictable
Better: Many effects will not be predictable. Climate interacts with complex biological and social systems, producing surprises.

…on forest ungulates…
Forests and ungulates form a coupled ecological system that operates over multiple scales in space and time.
Ungulates can facilitate or inhibit meeting forest management objectives.

…on forest ungulates…Ungulate herbivory is a key driver of forest structure, composition and dynamics.

…the paradox of "restoring" novel ecosystems
Adaptive strategies
1.Increase resiliency – manage for accommodating climate change2. Increase resistance – manage for resisting impacts
of climate change3. Facilitate transitions – manage for new conditions4. Realignment – create novel forest types
Stephens et al. 2010
