Title:
The Wildland-Urban Interface of the Conterminous United States 1990 - 2010 (geospatial data)
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
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.
Purpose:
To provide a spatially detailed national assessment of the Wildland Urban Interface (WUI) and WUI change between 1990 and 2010 across the coterminous U.S. to support wildland fire research, policy and management, and inquiries into the effects of housing growth on the environment.

Multi-Resolution Land Characteristics Consortium (MRLC) National Land Cover Dataset (NLCD) 2011, 2001, and 1992 Retrofit Land Cover Change Product Provided landcover information for identifying forest, grassland, and wetland areas (wildland vegetation).
Process_Step:
Process_Description:
1) Created nationwide map of "protected areas with no housing units", pulled from the PAD-US (CBI Edition) version 2, including all federal, state, regional, and local government owned lands. Intersected these protected areas with U.S. block level housing change 1990-2010 dataset and moved housing units out of protected areas into neighboring privately owned blocks with the same block ID (called public land adjustment or PLA). If the same block ID had no private areas then houses remained within the protected lands boundary (no adjustment).
Process_Date: 20170315
Process_Step:
Process_Description:
4) Selected all block housing polygons with >= 75% wildland vegetation in 2010 and dissolved into larger contiguous areas. Buffered areas > 500 hectares by 2414 m (1.5 miles) to identify potential interface WUI areas. Unioned 2010 buffers with integrated block housing polygons and assigned Interface WUI classes to all polygons falling inside vegetation buffers and minimum 6.177635 housing units / square km (ignoring pre-existing Intermix WUI areas) for all 3 decades 1990, 2000, 2010.
Process_Date: 20170315
Process_Step:
Process_Description:
3) Assigned 1990 Intermix WUI classes to all polygons with > 50% wildland vegetation in 1990 and minimum 6.177635 housing units / square km in 1990. Assigned 2000 Intermix WUI classes to all polygons with > 50% wildland vegetation in 2000 and minimum 6.177635 housing units / square km in 2000. Assigned 2010 Intermix WUI classes to all polygons with > 50% wildland vegetation in 2010 and minimum 6.177635 housing units / square km in 2010.
Process_Date: 20170315
Process_Step:
Process_Description:
2) Integrated U.S. block level housing change 1990-2010 dataset (public land adjusted) with the 2011 National Land Cover Dataset NLCD, 2001 NLCD, and the 1992/2001 Retrofit Change Product (1992 values only) using ArcGIS Tabulate Area command. Calculated wildland vegetation % for 3 decades (1990, 2000, 2010), with wildland vegetation defined as sum of relative percentages of land cover classes for forests, grasslands, and wetlands.

Entity_and_Attribute_Overview:
Spatial objects (features) do not model any real world entities. Spatial objects (features) can be thought of as uniform areas of housing density and landcover, which have been assigned a Wildland Urban Interface classification. Items pertaining to National Land Cover Data (NLCD) make use of the following classification: <http://www.mrlc.gov/nlcd11_leg.php>
