 Scenarios

There are six scenarios, each representing a global greenhouse storyline (IPCC 2007) paired with a harvest regime.

Moderate greenhouse gas emissions, moderate gains in population, and large gains in income and energy consumption (but with a balanced renewable/fossil fuel portfolio)

High greenhouse gas emissions, large gains in population and energy consumption, and moderate gains in income

Low greenhouse gas emissions with moderate gains in population, income, and energy consumption.

Harvest Regimes

-C
Scenario projections assume harvest will continue at recently observed levels
-BIO
Harvest will increase to reflect increased harvest for bioenergy production

Wisconsin Population by Scenario

Drivers of Forest Change

A large component of forest change will be the result of normal forest growth, aging, natural regeneration, and species succession. In addition, we expect that a range of external forces will also drive forest change:

  • Population increases will cause millions of acres of forest land to be converted to urban and other land uses.
  • Economic conditions will affect forest products consumption, production, and harvesting rates.
  • The spread of invasive species will exacerbate the effects of other disturbances on forest ecosystems.
  • Changes in population, economic activity, energy consumption, and energy production will affect future climate change.
  • Climate change will, in turn, affect dynamics within forested ecosystems, including patterns of vegetation growth and species succession.
