Wildfire Response Benefit Prioritization <br />It is necessary to conduct treatments to both improve for- <br />est health and reduce fire risk to communities as well as <br />provide conditions where firefighters can safely and effi- <br />ciently conduct fire operations (e.g. suppression, pre- <br />scribed burning, and managed wildfire). The wildfire <br />response benefit metric (WRB; Fig. 3) identifies and prior- <br />itizes locations where values at risk that are more likely to <br />be the focus of fire operations (homes, infrastructure, <br />sources of drinking water, and commercially managed <br />lands) coincide with areas likely to transmit wildfire to <br />homes and generate severe fire behavior. Because there <br />are positive feedbacks between healthy, resilient forests <br />and safe, effective fire operations, the WRB metric also <br />integrates the landscape treatment priority map (Fig. 1). <br />Where WRB is highest, actions may be needed to create <br />and maintain conditions that provide a tactical advantage <br />for fire operations. These actions will vary with the local <br />context and can include landscape-level forest health and <br />fuel treatments, treatments along escape routes, resident <br />and community fire mitigation activities (e.g. defensible <br />space, home hardening), and improving signage and road <br />conditions. The WRB metric provides a high-level prioriti- <br />zation, and additional work at the local level will be re- <br />quired to identify appropriate actions and assess their <br />feasibility. WRB is useful for prioritizing potential Control <br />Lines (PCLs) for fire operations (Fig. 4). pCLs are a part of <br />PotentialOperational Delineations (pODs); see page 3. <br />ln the Manastash-Taneum planning area, wildfire re- <br />sponse benefit is highest in the southeastern end of the <br />planning area where there is risk to homes (Thorp) and <br />infrastructure (lnterstate 90). Wildfire response benefit is <br />also high in the central portion on parcels of commercially <br />managed lands, and it is relatively lower in the western <br />portion of the planning area. <br />Definitions (continued) <br />Wildfire response benefit: Any tactical advantage <br />gained for wildfire response activities from actions <br />on the landscape including identifuing and consoli- <br />dating existing anchor points and control lines and <br />reducing potential fire behavior. Wildfire response <br />benefit is not restricted to any specific fire manage- <br />ment strategy; it is centered on conditions that im- <br />prove fire operations safety and efficary during <br />suppression, prescribed fire, or managed wildfire. <br />Potenttal Control Lines (PCLs): Boundaries of po- <br />tential Operational Delineations (PODs) relevant to <br />fire control operations (e.g. roads, ridgetops, and <br />water bodies). <br />Potential Operational Delineotions (PODs) for <br />wildland fire: Landscape containers whose bound- <br />aries are potential control lines (PCLs). PODs are <br />useful for planning strategic response to unplanned <br />ignitions, strategic fuel planning, and prioritizing <br />fuel treatments within PODs. <br />Commercially managed lands.. Commercially <br />managed forestlands include: DNR Trustlands, <br />tribal forests, industrial forests, non-industrial pri- <br />vate forests, and US Forest Service forests where <br />timber is a primary management objective. <br />Figure 3. Wildfire response benefit (WRB) integrates multiple fire risk and forest health components. lt includes four fire risk <br />metrics representing highly valued resources - risk to homes, infrastructure, drinking water, commercially managed lands - aswell as crown fire potential and wildfire transmission to homes (Fig. 2). Combined, these accountlor 75To of the wildfire re- <br />sponse benefit. Landscape treatment priority (Fig. 1) accounts for the remaining 25%. Also shown are pODs: units bounded by <br />PCls (open black lines). One use of the WRB metric is to prioritize Potential Control Lines (PCLs) for fire operations (Fig. a). <br />Manastash-Taneum Landscape Evaluation Summary Addendum (2020) | page 2 <br />Wildfire response benefit <br />,|.High <br />: <br />Low <br />PCL (boundary) <br />a <br />POD (interioQ
