Abstract: Pine dominated and dry mixed conifer Western forests are uncharacteristically dense and have high fuel loadings (Fulé et al. 2012). In Arizona, these conditions, combined with more than a decade of below average precipitation (Hereford 2007) and projected increasingly common droughts (Seager et al. 2007), have made these forests particularly susceptible to large, catastrophic wildfires. The 538,049-acre Wallow fire burned 418,277 acres on the Apache National Forest in the summer of 2011. Greater than 50% basal area (BA) mortality occurred on nearly 240,000 acres (USFS 2011). We began by identifying restoration opportunity areas based on vegetation type, canopy cover and tree diameter. Topography, watershed function, land management designations, and location relative to the Wildland Urban Interface were added to the analysis to identify more specific priority restoration areas. On the Wallow fire, all areas that fell within the restoration opportunity areas and had a basal area mortality of ≤50% were selected. Similar to the forest-wide analysis, areas within Wildland Urban Interface were identified.
