The Forests on the Edge feature class is based on the digital hydrologic unit boundary layer to the Subwatershed (12-digit) 6th level for the continental United States. This 2015 data set is an updated version of the 2011 Forests to Faucets data set. America’s private forests provide a vast array of public goods and services, including abundant, clean surface water. Forest loss and development can affect water quality and quantity when forests are removed and impervious surfaces, such as paved roads, spread across the landscape. In this study rank watersheds across the conterminous United States were ranked according to the contributions of private forest land to surface drinking water and by threats to surface water from increased housing density. Private forest land contributions to drinking water are greatest in the East but are also important in Western watersheds. Development pressures on these contributions are concentrated in the Eastern United States but are also found in the North-Central region, parts of the West and Southwest, and the Pacific Northwest; nationwide, more than 55 million acres of rural private forest land are projected to experience a substantial increase in housing density from 2000 to 2030. Planners, communities, and private landowners can use a range of strategies to maintain freshwater ecosystems, including designing housing and roads to minimize impacts on water quality, managing home sites to protect water resources, and using payment schemes and management partnerships to invest in forest stewardship on public and private lands.
The purpose of these data is to support the publication RMRS-GTR-327, Private forests, housing growth, and America’s water supply: A report from the Forests on the Edge and Forests to Faucets Projects. This dataset updates forest and development statistics reported in the 2011 Forests to Faucet analysis.

Data entry is accomplished by authorized Forest Service personnel through a web application behind the U.S. Forest Service firewall and is restricted by access requirement protocols.
Data is complete as of publication.
Generally the source information used to record spatial locations are from: 1) on-screen digitizing with a georeferenced topographic or image background; or 2) GPS field collected positions. Horizontal accuracy is variable.
To focus this analysis on watersheds with private forests, only watersheds with at least 10% forested land and more than 50 acres of private forest were analyzed. All other watersheds were labeled "Insufficient private forest for this analysis" and coded -99999 in the data table. This dataset updates forest and development statistics reported in the 2011 Forests to Faucet analysis using 2006 National Land Cover Database for the Conterminous United States, and Theobald, Dr. David M. 10 March 2008. bhc2000 and bhc2030 (Housing density for the coterminous US in 2000 and 2030, respectively.)
