Landscape Treatment Prioritization <br />Prioritizing for forest health &. to reduce fire exposure of homes <br />Landscape treatment priority integrates three metrics of forest <br />health - forest fire risk (Fig. 2), drought vulnerability (Fig. 3), and <br />presence of overabundant forest structure types (Fig. 4) - with <br />wildfire transmission to homes (Fig. 8). To ensure that habitat for <br />closed canopy dependent wildlife is incorporated into the prioriti- <br />zation, we recommend overlaying the large dense forest sustain- <br />ability layer (Fig. 7) when selecting treatment locations. Wildfire <br />transmission is high across the western half of the planning area, <br />representing potential fire exposure to communities in Liberty, <br />along the Highway 97 corridor, and in the Cle Elum area. <br />Treotment priorities <br />Treatment priority is particularly high in western and northern por- <br />tions of the planning area, reflecting high wildfire transmission on <br />the slopes east of Teanaway Ridge (Fig. 8). Within those areas, <br />north-facing slopes are especially high priority due to fire risk (Fig. <br />1) and current forest structure (Fig. 4). Treatment priority is gener- <br />ally lower in southeastern portions due to recent treatments near <br />Liberty and lower fire probability where the Table Mountain Fire <br />burned in 2012. Planned Swauk Pine treatments will help reduce <br />fire and forest health risks in remaining high priority locations. <br />Figure 8.
