A conceptual model of how people living at the wildland-urban interface evaluate acceptability of three fuel management approaches (prescribed fire, mechanical treatment, and enforcement of defensible space ordinances) was developed from focus group interviews, and a set of standardized, nationally applicable measurement scales and indicators was developed. Now tested in interface communities in three states, these scales and indicators enable cost-effective, manager-directed surveys to assess local perceptions, understanding and support for fuel management. Survey results were also useful for comparing acceptance, attitudes and beliefs of interface residents in distinctly different parts of the U.S., with different cultural norms and prevailing fire regimes. The study also attempted to develop models for predicting acceptance from demographic and geographic characteristics of interface residents that could be used to predict acceptance at un-surveyed locations. Unfortunately, this proved infeasible because our research found that statistically significant relationships between acceptance and these attributes did not exist. Spatial continuity of perception, understanding and acceptance were explored in an effort to design spatially unbiased sampling frames and to evaluate the feasibility of interpolating sparse sample data to produce spatially comprehensive maps of fuel treatment acceptance that could support targeted education and outreach intervention activities.
