We operationalized a policy definition published in the Federal Register (US Department of the Interior [USDI] and US Department of Agriculture [USDA]), 2001, Urban wildland interface communities within vicinity of federal lands that are at high risk from wildfire. Fed. Regist. 66(3):751-777) to create national maps and statistics of the WUI to guide strategic planning. Using geographic information system analysis, we evaluate the national WUI by altering the definition’s parameters to assess the influence of individual parameters (i.e., housing density, vegetation type and density, and interface buffer distance) and stability of outcomes. The most sensitive parameter was the housing density threshold. Changes in outputs (WUI homes and area) were much smaller than parameter variations suggesting the WUI definition generates stable results on most landscapes. Overall, modifying the WUI definition resulted in a similar amount of WUI area and number of homes and affected the precise location of the WUI.10aGIS sensitivity analysis10aHousing growth10awildland fire10awildland fire policy10awildland-urban interface1 aStewart, Susan, I.1 aRadeloff, Volker, C.1 aHammer, Roger, B.1 aHawbaker, Todd, J. uhttp://www.ingentaconnect.com/content/saf/jof/2007/00000105/00000004/art0001200844nas a2200241 4500008004100000022001400041245013100055210006900186300001400255490000700269653001900276653002100295653002000316653001900336653002100355653001100376100002200387700002300409700002600432700002500458700001900483856010000502 2004 eng d a0169-204600aCharacterizing dynamic spatial and temporal residential density patterns from 1940-1990 across the North Central United States0 aCharacterizing dynamic spatial and temporal residential density a183 - 1990 v6910aAmenity growth10aCluster analysis10aHousing density10aHousing growth10aLandscape change10aSprawl1 aHammer, Roger, B.1 aStewart, Susan, I.1 aWinkler, Richelle, L.1 aRadeloff, Volker, C.1 aVoss, Paul, R. uhttp://www.sciencedirect.com/science/article/B6V91-4BBHBTN-2/2/ab6ac67484362a8153ba5817d8f7cec6
