Among key findings:

--Urbanization could reduce the amount of forests -- up to 23 million acres, roughly the size of South Carolina -- and change their character.

--More people means more demands for additional goods and services from a declining forest base.

--Wildfire potential increases; more numerous and more severe fires are forecast.

--More frequent and intense wildfires will pose additional challenges to community and forestry wildfire organizations.

--Population growth will bring more runoff from roads, buildings and parking lots, as well as increased pollution, affecting clean drinking water and the quality of aquatic habitats.

--The spread of plant, insect and disease pests could severely affect native species, forest productivity and wildlife.

--More than 1,000 plant and wildlife species of conservation concern could be threatened by urbanization, climate change and invasive species.

--Forests could support higher levels of timber harvest than present, but demands are uncertain, especially for bioenergy.
