The Landscape Treatment Designer (LTD) is a multicriteria spatial prioritization and optimization system to help design and explore landscape fuel treatment scenarios. The program fills a gap between fire model programs such as FlamMap, and planning systems such as ArcFuels, in the fuel treatment planning process. The LTD uses inputs on spatial treatment objectives, activity constraints, and treatment thresholds, and then identifies optimal fuel treatment locations with respect to the input parameters. The program can be used in a number of ways to explore treatment priority and decision rules as they manifest themselves on small to large (1 million ha) landscapes as spatially explicit treatment strategies. This webinar was hosted by the Wildland Fire Lessons Learned Center, the Joint Fire Science Program, and the International Association of Wildland Fire.
