The Wildland-Urban Interface (WUI) is the area where houses meet or intermingle with undeveloped wildland vegetation. This makes the WUI a focal area for human-environment conflicts such as wildland fires, habitat fragmentation, invasive species, and biodiversity decline. Using geographic information systems (GIS), we integrated U.S. Census and USGS National Land Cover Data, to map the Federal Register definition of WUI (Federal Register 66:751, 2001). These data are useful within a GIS for mapping and analysis at national, state, and local levels.
To provide a spatially detailed national assessment of the Wildland Urban Interface (WUI) across the coterminous U.S. to support wildland fire research, policy and management, and inquiries into the effects of housing growth on the environment.

7) Selected vegetation buffers along state borders and unioned into a single US buffer dataset. Overlaid (Identity) US buffer with each state integrated TIGER polygon dataset to classify Interstate Interface WUI polygons across state borders.
3) Integrated TIGER block geography (with housing units moved out of protected areas) with the 2006 National Land Cover Dataset NLCD (using ArcGIS Tabulate Area command). Wildland Vegetation defined as sum of relative percentages of land cover classes for Forests, Grasslands, and Wetlands.

1) Created a nationwide map of "protected areas with no housing units". These areas were pulled from the PAD-US 1.1 (CBI Edition) and included all publicly owned areas - federal, state, regional, and local government owned lands.
PAD-US 1.1
2) Intersected PAD derived no housing unit protected areas with TIGER block geography and moved housing units out of these areas into neighboring privately owned blocks with the same block ID. If the same block ID had no private areas then houses remained within the protected lands boundary (unmoved).
PAD-US 1.1
TIGER
6) Unioned vegetation area buffers with integrated TIGER/Intermix WUI polygons and assigned Interface WUI classes to all polygons falling inside vegetation buffers and minimum 6.177635 housing units / square km (ignoring Intermix WUI areas).
4) Assigned Intermix WUI classes to all polygons with > 50% wildland vegetation and minimum 6.177635 housing units / square km.
5) Selected all TIGER polygons with >= 75% wildland vegetation and dissolved into larger contiguous areas. Buffered areas > 500 hectares by 2414 m (1.5 miles) to identify potential interface WUI areas.
PAD-US 1.1 (CBI Edition) is a comprehensive geospatial data set of United States protected areas, including detailed information on land ownership, management and conservation status.
