FREDONIA – North Zone fire managers on the North Kaibab Ranger District of the Kaibab National Forest and the North Rim of Grand Canyon National Park have announced locations where they plan to complete prescribed fire projects starting in October and continuing through the spring of 2018. Approximately 13,850 acres could be eligible for treatment across the plateau, but the implementation of each project will only occur when weather, fuel moisture, and smoke dispersal conditions are within the defined prescription parameters.

The role that prescribed fires play includes decreasing risks to life, resources, and property. Fire managers carefully plan prescribed fires, initiating them only under environmental conditions that are favorable to assure firefighter and visitor safety and to achieve the desired objectives, which include reducing accumulations of hazard fuels, maintaining the natural role of fire in a fire-adapted ecosystem, and protecting sensitive cultural and natural resources.

This season’s planned treatment areas are as follows:

Thompson Unit: The Thompson prescribed burn unit (Thompson Rx) consists of dense vegetation and heavy dead and down fuels that are predominantly composed of spruce, fir, and aspen. The ignition portion of the Thompson Unit is approximately 2,000 acres, and the project area is located both on the North Rim of the Grand Canyon and the North Kaibab Ranger District, on the east side of AZ Highway 67 and directly east of the North Rim entrance station. Objectives include reducing accumulations of hazardous fuels by 40 percent.

Smoke impacts may include Highway 67, the North Rim Entrance Station, DeMotte Park and portions of the Grand Canyon including the Nankoweep area and Kwagunt Valley area. Additional smoke impacts may occur in the Marble Canyon area and as far away as Page.

Moquitch 3 Unit: The Moquitch 3 prescribed burn unit (Moquitch 3 Rx) consists of vegetation that is predominantly ponderosa pine with scattered clumps of aspen and patches of New Mexico locust. The unit is approximately 3,500 acres and is located about 6 miles south of Jacob Lake. Objectives include reducing accumulations of hazardous fuels down to 5 tons-per-acre and stimulating aspen regeneration in areas where mature clones exist.

Smoke impacts may include Jacob Lake, AZ Highway 67 and AZ Highway 89A.

Tipover East Unit: The Tipover East prescribed burn unit (Tipover Rx) consists of vegetation that is predominantly first-entry mixed conifer, which in this case means the area has not seen fire disturbance in more than 100 years and therefore contains above-average fuel loads potentially posing a higher risk of a large-scale wildfire. Fire managers plan to treat approximately 2,500 acres for this season. The unit is located on a strip of forested land along the boundary of Grand Canyon National Park and the Kaibab National Forest west of Highway 67. Objectives include reducing accumulations of hazardous fuels and protecting sensitive cultural and natural resources.

Smoke impacts may include Highway 89A, Highway 67, Marble Canyon and other high-use visitor areas.

North Rim Slopes Unit: The North Rim Slopes prescribed burn unit (Slopes Rx) also consists of vegetation that is predominantly first-entry mixed conifer. Fire managers plan to treat approximately 2,500 acres for this season. The unit is located along the north boundary of Grand Canyon National Park, west of Highway 67. Objectives include reducing accumulations of hazardous fuels by 25 percent and returning fire to a fire-adapted ecosystem.

Smoke impacts may include Highway 67, the North Rim Entrance Station, DeMotte Park and portions of the Grand Canyon.

Wildhorse Unit: The Wildhorse prescribed burn unit (Wildhorse Rx) consists of vegetation that is predominantly Ponderosa pine, Pinion pine, Juniper and a few scattered clumps of Aspen. The unit is approximately 2,800 acres and is located near Jacob Lake. Objectives include reducing accumulations of hazardous fuels down to 5 tons-per-acre and protecting sensitive cultural and natural resources.

Smoke impacts may include Forest Service roads north of Jacob Lake, Highway 89A, Jacob Lake developed area and the LeFevre overlook.

High Severity Edge Unit: The High Severity Edge prescribed burn unit (High Severity Edge Rx) consists of vegetation that is predominantly ponderosa pine and mixed conifer. Fire managers plan to treat approximately 500 acres for this season, and the unit is located on the Walhalla Plateau, west and south of Cape Royal Road. Objectives include limiting high severity fire effects in forested areas adjacent to or near patches of past high-severity wildfires.

Smoke impacts may include Highway 67, the North Rim Entrance Station, DeMotte Park and portions of the Grand Canyon.

Bright Angel Unit: The Bright Angel prescribed burn unit (Bright Angel Rx) consists of vegetation that is predominantly ponderosa pine. Fire managers plan to treat approximately 50 acres this season, and objectives include reducing fuel accumulations, creating a defensible space around structures in the developed area on the North Rim of the Grand Canyon and protecting sensitive cultural and natural resources.

Smoke impacts may include portions of the Grand Canyon.

North Zone Pile Burns (Pile Rx): Fire managers will also spend time preparing to burn piles of woody debris as resources and weather conditions allow. These piles are typically composed of vegetative materials, commonly called slash, such as tops, limbs, branches, brush, and other recently cut miscellaneous materials resulting from forest management activities such as thinning, pruning, timber harvesting, and wildfire hazard mitigation. Upon arranging slash into compact, teepee-shapes and allowing the piles to dry, fire managers will burn the piles during safe burning conditions, generally after a snowfall or significant wetting-rain events.

During prescribed fires, motorists are cautioned that smoke may be present in short durations, which may impact roads and populated areas, and are reminded to use caution, drive slowly, turn on headlights, and avoid stopping in areas where fire personnel is working.

As a reminder, all prescribed burning is subject to approval by the Arizona Department of Environmental Quality and appropriate weather conditions.
