Structure and Area Description
Property Description and Ownership
Lantz Bar is an Administrative Site of the United States Forest Service located within the FC-RONRW. This site is managed by the Bitterroot National Forest. The site is located 70 miles NE of McCall, Idaho along the Main Salmon River.
The site consists of 3 structures, 2 cabins and an outhouse. There is a water tank also located on site. This is a very remote site and access is only by boat or helicopter. The apple orchard is the only area to be protected at this site. The builds do not require structure protection.
The Bitterroot National Forest has management responsibilities, the Krassel Ranger District on the Payette National Forest assists in the protection of the structure during WFU fires on the South side of the Salmon River.

Topography and Fuel Modeling

The administrative site is situated on a large gassy flat along the Main Salmon River in the valley bottom. Topography of the river canyon is characterized by extremely steep slopes bisected by numerous secondary ridges and draws resulting continuous subtle aspect changes. Fire behavior will be locally influenced by changing aspects but historical large fire movement, burning over an extended period has been toward the northeast.

Fire Behavior Models (H.E. Anderson): The dominant over story structure of the Salmon River Canyon is Ponderosa Pine, Douglas fir pockets can be found dispersed through out the Basin depending on aspects, elevation, and water availability. Fuel modeling locally is an extensive Ponderosa Pine with grass sagebrush under story, representing FM-2 with numerous pockets of large woody downfall, FM-8. The Bear WFU of 2005 burned the west side of the river. This has left many snags in the area, while reducing the fuel levels at the same time.

Wilderness Considerations
The Lantz Bar site is located within the FC-RONR Wilderness. Suppression and protection efforts on Federal Wilderness lands will have constraints, concerns, and special needs that will have to be resolved or mitigated depending o the situation before implementation. In the event of structure protection implementation, a district Wilderness Resource Advisor will be notified and assigned to the protection overhead cadre. Listed below are primary items that an Incident Commander will need to consider when implementing structure protection on Federal Wilderness lands.

  • Soils

  • Fisheries

  • Archeology

Protection Implementation
The decision to implement structure protection will be based on current and predicted weather, fuels, and fire behavior. When fire(s) is burning in the vicinity, a Fire Behavior Analyst should be assigned the responsibility on monitoring the fire and keeping the District Ranger and Fire Staff informed on the fire’s behavior and progression. Protection provisions must be made well in advance of the fire’s burning into the fuels adjacent to the developed site. The plan should be implemented a minimum of three days prior to the fire’s expected arrival to the site. Previously ignited wildland fires burning to within a mile or new ignitions within the mile radius should be red flagged with daily monitoring and fire behavior predictions using the daily and three day forecasts. Personal observations and predictions by an experienced FBA during times of extreme fire conditions will be essential for the timely implementation of structure protection ground work.

Tactical Strategies

When the decision is made that protection is needed, crews and equipment will hike or pack string to the site. “Light Hand” tactics are preferred and advocated. On site evaluation should determine where, how much, and type of protection systems will be needed. Protection of the site may not require completely ling the sites perimeter. The IC should in applicable situations, get consensual agreement with the assigned incident Resource Advisor on the applicability of handlines, back burning, falling timber or other protection strategies that could result in long term damage to local resources. In the past, the only action taken in site protection was the use of structure wrap for the historic log cabin. With the heavy fuel loading in the surrounding area, firefighter safety is a concern and actually leaving firefighters at the site for structure protection might not be feasible.
