Overview
This report is one of several produced by the U.S. Department of Agriculture, Forest Service as part of the Forests on the Edge project. It displays and describes information at a national level that can improve understanding of forest land development issues.
Key Points Covered
- Areas nationwide where private forests make substantial contributions to clean water, timber volume, habitat for at-risk plant and animal species or interior forests
- Where private forest contributions are likely to change because of increased housing density
- Locations where change from increased housing density is likely to be exacerbated by other factors such as insect pests and diseases, wildfire, or air pollution
- Private forest lands that are making the most important contributions are also facing the greatest pressures in certain areas throughout the country
Top 15 watersheds in terms of total acreage of private forest projected to experience increased housing density
Study Results
Private Forests, Public Benefits has identified areas where the following goods and services will be most affected by future forest land development:
- Forest cover: Watersheds in the East rank highest for increased housing density on private forests. Highly ranked watersheds are also located in Washington, Colorado, and California.

Click here for a table of the top 15 watersheds - Interior forest: Watersheds where interior forest is most likely to be reduced by increased housing density are found along an axis stretching from Maine to Louisiana, as well as along the coasts of South Carolina, Georgia, and northern Florida. High-ranking watersheds are also found in coastal Washington, California's Sierra Nevada range, and in the vicinity of Denver, Colorado.

Private Forest, Public Benefits also identifies areas where the impacts of future development could be exacerbated by the following threats:
- Insect Pests and Diseases: Watersheds with private forests under greatest pressure from insect pests and diseases as well as housing development are scattered throughout the country. Eastern watersheds are found in New England, New Jersey, Pennsylvania, North Carolina, South Carolina, and Michigan. In the West, high-ranking watersheds are found in western Montana, Oregon, California, and the southwest.

Watersheds with private forests most at-risk from wildfire and housing development combined are scattered across the West and the southeast.

Private forests are experiencing increases in housing density in every region of the United States. With the U.S. population projected to increase by at least another 80 million people by 2030, forest resource managers should anticipate and prepare for continued development pressures on the Nation's private forests.
