Prescribed Burn Plan
Bennett Lumber Products Inc.
Prepared By: Tom Biltonen
Forester, Bennett Lumber Products
This Prescribed burn will consume logging slash from Bennett Lumber’s Hitchner- Hatter Creek
Unit. This controlled burn will reduce hazard fuels and prepare the area for planting in the Spring
Location: The treatment area is located approximately 6 miles south of Princeton Idaho off of the
Hatter Creek County Road.
Legal Description: Pts. SENE Sec 10 Twnshp 40N, Range 4W
Pts. S2NW Sec 11 Twnshp 40N, Range 4W
Unit Description: This unit was harvested during the spring and summer of 2002. The
silvicultural prescription was clearcut with reserves. Approximately 50 percent of the area had
been commercially thinned approximately 12 years prior. The stand consisted primarily of Grand
Fir, Douglas Fir and Western Red Cedar; with a smaller component of Western Larch, Ponderosa
Pine and Western White Pine. A high component of the trees within the unit were over mature
and indicators of both root and stem diseases were present throughout the stand. The area was
clearcut with any vigorous Western Larch or Ponderosa Pine retained for seed and future wildlife
considerations. Due to steep terrain and erosion concerns the area was harvested with a skyline
Size and Perimeters: The burn area is 53 acres in size. Roads border the upper, lower and west
sides of the unit. The east side has a crawler line fuelbreak and a 43 acre unit which was burned
in the Fall of 2002.
Elevation: 3320 - 3100 feet
Landform: Slope: 30-70% average 50%
Vegetation: Some large Western Larch and Ponderosa Pine were retained and are scattered
throughout the unit. Heavy concentrations of Vine Maple were located within the unit, most of
these areas were slashed in August of 2002. A few scattered areas of this brush and an occasional
island of 10 to 15 foot regeneration make up the majority of the remaining vegetation.
Fuels: Fuels within the unit consist of medium red logging slash NFFL Fuel model 12 [Morgan
and Shiplett, 1989]. The area was strip sawed (limbed and topped in the woods) so the slash is
fairly evenly distributed throughout the unit. Surrounding fuel types vary from recently burned on
east side, Fuel model 10, timber with litter, on the south side, and Fuel model 12 , medium
logging slash, on portions of the northern and the west sides. Perimeter areas with fuel model 12
were treated during the Fall of 2002 with any heavy concentrations of fuel adjacent to the unit
Climate and Weather: With the mild winter and recent precipitation this area should be suitable
for a spring burn after a wet weather systems and subsequent drying.
Land Management Objectives: The main objective for this unit is to regenerate this area to seral
tree species of Ponderosa Pine, Western White Pine and Western Larch for timber management.
To accomplish this task a prescribed burn will be required to reduce accumulated slash left over
from timber harvesting activity. This is required to reduce hazard fuels and prepare the area for
Treatment Objectives: Specific objectives include: provide aid in planting operations, reduce
planting costs and seedling mortality as well as reducing of future hazards via fuel reduction and
fuel breaks. Planting density will be approximately 400 trees per acre, this prescribed burn should
consume slash to provide this spacing but also retain large woody debris for planting microsites
and future soil wood. Numerous seed trees are also located throughout the stand this fire will be
conducted under conditions to preserve as many of theses trees as possible. This burn will be
conducted in a manner that will accomplish these two objectives and, most importantly, provide
for safety of all personnel involved and preservation of the surrounding areas.
Air Quality: The area is approximately 6 miles south of Princeton Idaho and some residences are
located within a mile of the burn area. These areas are located downslope and away from
prevailing winds in the area. Burning will be conducted at such a time to assure that atmospheric
conditions will allow for proper smoke dispersal.
Water Quality: A few intermittent swales are located within the unit, the burn should be of low
intensity and not significantly degrade these features. Fuelbreaks are currently waterbared and, if
necessary, required areas will be grass seeded.
Soils: Burning will be conducted within prescribed limits to meet objectives, provide a safe burn
and protect the soil resource.
Operational: Burning will be coordinated with personnel from Bennett Lumber Products and
Idaho Department of Lands. Bennett Lumber personnel will be utilized for holding and igniting
crews as well as equipment mobilization and standby. IDL coordination will be used to assure
adequate resources are available if required.
Excavator Pile and Burn Piles: The majority of the area is too steep to safely operate a excavator.
In areas where it could operate a high percentage of soil disturbance would occur. Subsequent
burning of the piles would create intense heat which would “cook” soils below and around the
piles making these areas useless for tree growth.
Plant without burning: Not a viable alternative, adequate coverage for planting would not be
attained or would the obligation of hazard reduction be met.
Consume at least 75 percent of all 1 and 10 hour fuels while still retaining any large organic
Prepare the area for planting by providing a minimum of 400 sites per acre
Preferred and Acceptable Range of conditions for Prescription:

Monitoring for Desired Conditions:
Once conditions and weather patterns moderate to “Spring-like” conditions, fuel moisture and
atmospheric conditions will be monitored. Fuel moisture will be measured with a electronic
moisture meter and weather data with a field weather kit. Once conditions and weather forecasts
are favorable outlined Agencies will be notified and the burn will commence as per this plan.
Preparation for Burning The burn unit is surrounded on three sides by roads approximately 14 feet
in width. Both upper, lower and west ends of the unit are bounded by this road. This road is
accessible to all suppression equipment to be utilized on this burn. The east end is bounded by a 5
foot fireline and a previously burned area from last fall.

IGNITION: Ignition will begin on the upper and far end of the unit adjacent to the road,( southeast
corner). Ignition will continue to the west and proceed down hill to the north.
FIRING TECHNIQUE: Ignition personnel will be directed via radio. The primary burning
technique will be a Strip-Head Fire. If fuel moisture contents are within the lower ranges of
acceptable limits and fire behavior is deemed beyond preferred ranges, ignition tactics will
change. If these conditions are present the preferred method of ignition will be a backing fire with
some Spot (Point Source) Firing techniques being utilized. Distance between lines and spots
within the line will be spaced to assure a lower intensity burn and prevention of a continuous
TEST FIRE: The first ignition point will be evaluated by the burn boss and personnel prior to full
Holding crews will be placed along the upper end of the burn unit. The area above the burn will
be monitored for spotting and burning operation ceased if excessive spotting occurs. Engines will
be placed in strategic locations to support holding personnel where required and when safety
Mop Up and Patrol
Any spot fires outside of the burn unit boundary will be contained and manned till deemed 100%
out; as soon as it is safely possible to do so. The unit and surrounding area will be patrolled daily
until the fire is deemed OUT.
If the fire should exceed the capabilities of the burn team, the Burn boss will:
1. Contact backup from resources available at the Bennett mill
2. Contact IDL Deary Office
A safety briefing will be conducted prior to any burning operations. This meeting will cover
personnel responsibilities, organization, communications, various features of the unit, escape
routes, safety zones and what to do in case of a medical emergency. Plans for ignition, potential
safety hazards and firing safety will also be discussed. The holding crew and engines will be
staged at predetermined locations.
All personnel will be required to wear full nomex, hard hats, fire shelters, leather gloves, and
leather boots. Support vehicles will be parked facing out and away from firing operations.
Vehicles involved with holding operations will always be manned, facing out and have windows
Prior to ignition the following Agencies will be contacted:
IDL Deary Office 208-877-1121
Latah County Sheriff 208-882-2216
Potlatch Rural Fire 208-875-0111
A post burn evaluation will be conducted by the Tom Biltonen. Overall safety, operations and
crew performance will be evaluated along with fuel consumption, planting sites, residual tree
damage and soil damage/enhancement.
