Basics
A geographic information system-based decision support system, called OptFuels, was developed as part of a SNPLMA-funded project for spatially scheduling forest fuel treatments over multiple planning periods in the Lake Tahoe Basin. OptFuels combines the vegetation simulation capabilities of the Forest Vegetation Simulator (FVS), the landscape fire behavior modeling functionality of the Minimum Travel Time algorithm in FlamMap (FlamMap-MTT), and a heuristic algorithm for scheduling fuel treatments. This integrated system provides land managers with a streamlined ability to develop spatiotemporal fuel treatment alternatives and assess trade-offs among various alternatives and no action.

Threshold Categories
-
Many communities in the Lake Tahoe Basin are at high risk for damage from wildfire. The USDA Forest Service Lake Tahoe Basin Management Unit (LTBMU) and other land management agencies in the Basin have conducted fuel treatments on numerous acres, primarily within the wildland urban interface, and there are plans to treat over 68,000 acres of forested areas within the Basin over the next 10 to 15 years.

| 07/27/2017 3:21 PM | Kiara Cuerpo-Hadsall | Objectives: • Add functionality to OptFuels for users to enter treatment unit polygons with assigned treatments for project alternatives and analyze the effectiveness of those proposed treatments to modify fire behavior and reduce the risk from future wildland fire. • Construct a Lake Tahoe Basin-wide OptFuels database and develop a streamlined process for clipping and building OptFuels models that are tailored to specific planning areas. • Enhance the fuel treatment information provided by OptFuels that can be used in designing projects to meet various forest management objectives. • Enhance the capability of OptFuels to predict wildfire effects on erosion and water quality and on various values at risk both with and without fuel treatments across user-specified fire scenarios. • Deliver the enhanced OptFuels system to end-users. |

| 07/27/2017 3:20 PM | Kiara Cuerpo-Hadsall | Findings: The following tools were created: • Custom project layers based on existing stand polygons or by using the default data using a ‘click and drag’ GIS interface. • Model a treatment scenario based on user-defined stands and treatment types. • Provide the capability to parameterize and run the OptFuels model and analyze outputs directly from the custom ArcGIS toolbar. • ‘Compare Outputs’ tool showing the difference in Arrival Time, Flame Length, and Expected Loss between No Action and Treatment. *** See www.fs.fed.us/PSW/partnerships/tahoescience for additional findings. |

| 07/27/2017 3:19 PM | Kiara Cuerpo-Hadsall | Management Implications: • This integrated system provides land managers with a streamlined ability to develop spatiotemporal fuel treatment alternatives and assess trade-offs among various alternatives and no action. • Trade-offs can be assessed in terms of effects on fire behavior including flame length and fire arrival time across the landscape, expected loss to values at risk, and sediment loading in stream channels if wildfire were to occur. • Forest vegetation is modeled through time and can also be compared across treatment alternatives, including no action. • In addition to fuel treatment optimization by the heuristic algorithm, users have the option of entering their own treatment alternatives for analyzing effects on fire behavior and conducting trade-off analyses. |
