Ranger District
2Why is the project proposed?
PRIMARY FOCUS--To improve firefighter and public
safety by reducing fuels on public lands around
the wildland urban interface (WUI), evacuation
routes, and in strategic fuel breaks.
To avoid these situations.
OTHER OBJECTIVES
To reduce insect and disease susceptibility in
treated areas.
To enhance aspen habitat
3Background
- Lonesome Wood Vegetation Management proposal is
an outcome of the Hebgen Watershed Risk
Assessment, completed in November 2005. The Risk
Assessment was a landscape level coarse
assessment of the danger of wildfire to a variety
of resources in this area, if no management
actions are taken. The watershed assessment
evaluated approximately 68,000 - acres north, west and southwest of Hebgen
Lake. The interdisciplinary team that conducted
the analysis considered existing, historical, and
projected future landscape conditions, and
weighed these considerations with current Forest
Plan management direction and the current and
projected social setting. - Within the project area there are private
residences with business operations. The project
area also includes 34 recreation residences in
four summer home groups including Lonesomehurst,
Romset, Rumbaugh, and Clark Springs. There are
more than a dozen dispersed recreation areas,
four developed recreation sites, access for 8
trail systems and 15 forest road systems.
Several hundred people may be recreating or
conducting business in the vicinity on a typical
summer day. - Direction in the GNF Forest Plan (1987) as
amended, and the National Fire Plan (2000) was
incorporated in the design of this proposal. The
proposal meets the intent of the Healthy Forest
Restoration Act. - Gallatin County has a draft Community Wildfire
Protection Plan (CWPP), which is scheduled to be
published in Spring 2007. The entire Lonesome
Wood Vegetation Management project area is
identified in the draft CWPP as a WUI area at
risk from wildfires. A CWPP identifies areas for
hazardous fuel reduction treatments, sets
priorities for treating them, and recommends the
types and methods of treatment on Federal and
non-Federal land that will help protect one or
more at risk communities and their essential
infrastructure. (HFRA Website)
4Where is the proposal ?
- The project area is located on National
Forest System (NFS) lands on the west side of
Hebgen Lake near the community of West
Yellowstone, MT. - The Lonesome Wood Vegetation Management
project area extends from Highway 20 on the
south, Hebgen Lake on the east and north.
5What is proposed?
- Vegetation treatments that reduce wildland fuels
are the primary focus of the project around the
wildland-urban interface (WUI) and evacuation
routes. In addition, treatments on areas in and
adjacent to WUI are designed to meet fuel and
other resource objectives. - Thinning and/or prescribed burning is proposed on
about 3,200 acres within the 24,000 acre project
area. The primary treatment activity is described
and is identified in the table and on the
Proposed Action maps in this program.
Treatments within the individual units vary, and
as a result, inclusions of multiple treatments
are often incorporated.

7Activities and Desired Outcome
- Reduce Stand Density by Thinning.
- Units identified for commercial thin may have any
size class of tree removed. A ground based
logging system would be the primary method of
tree removal. Trees over six inches in diameter
would most likely be skidded to landings and
hauled offsite for use as a commercial product.
Trees less than 6 inches in diameter may also
need to be removed in conjunction with commercial
logging, as described in the next paragraph. - Units identified for small tree removal either
have trees with mixed ages or are primarily small
trees. Treatment would be limited to trees
smaller than 6 inches in diameter. The
treatment may be implemented by hand or with
tracked equipment that would facilitate removal
of the biomass from the landscape. Skid or access
trails may be needed in these units to facilitate
removal of biomass. On slopes greater than 35,
the thinning and associated treatments would be
implemented by hand.
- Desired Outcome
- The desired tree spacing along the road and in
the WUI is 20-30 feet between trees. Beyond the
400 in the evacuation routes in fuel breaks,
trees would be denser at about 15-20 between
trees. An estimated 40-50 of the total trees
in a stand would be removed. In units with bark
beetle concerns spacing would be about 30-40 feet
between trees. - The desired tree spacing for this treatment is
the same as described above. In addition, in
some units the current stand condition is not
suitable for thinning. In these units the
overall stand density would be reduced by about
40 by creating small openings between 1/3 to 5
acres. This prescription would be implemented
primarily in units where trees less than 6 inches
in diameter are the target for removal.
8Activities and Desired Outcome
Aspen Management Maintenance of Low Fire Risk
Areas
Desired Outcomes
- Prescribed burning Remove conifers within and
about 1 ½ tree lengths out from the clone.
Monitor aspen sprouting response, and implement a
broadcast burn to further stimulate sprouting if
needed. In some other areas with relatively few
trees, broadcast burn to maintain open areas. - Activities may include but are not limited to
thinning through logging, yarding unmerchantable
material, piling, hauling of commercial material,
slashing small trees, firewood removal, biomass
reduction such as chipping, pile burning,
broadcast burning, erosion control,
rehabilitation of skid trails, landings and
temporary roads. - Biomass less than 6 in diameter may be removed
mechanically for commercial purposes. - An estimated 3.5-4.5 miles of temporary road
would be needed to facilitate log removal in
commercial thin units. Temporary roads would be
used for implementation of the project, then
closed. Rehabilitation includes erosion control,
scarification and seeding. If needed, closure
devices would be installed to eliminate future
use
- Help reduce competition for sunlight and water
and stimulate sprouting in aspen forest. - Where the existing condition is open and has a
low risk of severe fire, - maintain as open areas.
- In all units, natural and activity related fuels,
including boles, branches and tops would be
reduced to 10-15 tons of woody material. Some
large woody material would be left to meet the
Forest Plan requirements for snags and downed
woody material. (GNF Plan, 1987, Amendment 15). - Biomass material is a by product of fuels
reduction treatments. At this time there is not a
market to facilitate biomass removal around West
Yellowstone. The sale of biomass would utilize
fuels and lessen the amount of pile burning
required to achieve desired fuel conditions. - The temporary roads would maintain skid distances
of ¼ mile or less. - Erosion control and revegetation protects site
productivity and minimizes the introduction and
spread of undesirable species.

11Project Implementation
Full implementation of the project could take
5-10 years.
- Proposed activities could be accomplished with
Forest Service crews, service contracts, timber
sale contracts and/or stewardship contracting. - Through stewardship contracting the value from
the wood products removed and sold could be
re-invested into the project area. - The District will continue communication with
private land owners and recreation residence
owners of the importance of Firewise principles.
Application of Firewise principles will help
owners maintain defensible space around their
property and reduce structure ignitability.
12Wildland Urban Interface
Treatment units proposed within the WUI extend
approximately ½ mile from the structures. The
distance is based on fire behavior modeling. The
model estimated that firebrands from expected
crown fire may be lofted and carried up to ½ mile
away given the existing fuel conditions.
The risk of sustained crown fire is high in and
adjacent to much of the WUI in the project areas.
Surface and ladder fuels are conducive to intense
fire with torching that pushes a fire from the
ground to the tree crowns. Crown canopy fuels
are continuous and lend themselves to fire
spread from crown to crown for long distances
and are likely to produce lofting firebrands.
Lonesome Hurst Summer Homes
Private homes adjacent to NFS land along Denny
Creek Road
Continuity of surface, ladder and crown fuels
would be reduced, resulting in elevated canopy
base height and reduced fuel continuity in all
fuel strata or layers (surface, ladder and
crown). The changed condition would lower the
fire intensities and result in a change to
predicated fire type from crown fire to surface
fire.
13Evacuation Routes
The Denny Creek Road provides the only road
access to the west shore of the lake and is the
primary evacuation route. The route is narrow,
with heavy forest fuel accumulations immediately
adjacent to the road. Expected flame length and
fire intensity is high along the route.
Additionally, intense crown fires can generate
very high winds, which may preclude evacuations
by water.
Denny Creek Road
Treatment units addressing evacuation routes are
limited to approximately 400 feet either side of
the roadway. Fire intensity and flame length
would be reduced immediately adjacent to the
roadway to allow safe ingress or egress. The
Incident Response Pocket Guide and computer fire
prediction models were used for guidance to
derive the proposed distance.

14Fuel Breaks
To improve the effectiveness of fuel treatment in
the WUI and evacuation routes, strategic fuel
breaks would be created.
Propose unit 7 just above Denny Creek Road
Within the project area, there are extensive
areas of difficult terrain with dense forest.
These are important to treat, however the
treatments, consisting of hand-sawing and
piling, would be expensive. To offset the cost
of this work, some adjacent areas on gentler
ground, that have larger trees (over 6 inches in
diameter), would be thinned.
Similar stand conditions to fuel break area in
proposed unit 26 above the Denny Creek Rd.
- The thinning would improve the
effectiveness of the hand treatments, while
providing some revenue to offset the cost of hand
treatments. In these areas, continuity of
surface, ladder and crown fuels would be reduced,
resulting in elevated canopy base height and
reduced fuel continuity in all fuel strata or
layers (surface, ladder and crown). The changed
condition would lower fire intensities and reduce
the chance of crown fire.

15Aspen Management Maintenance of Low Fire Risk
Areas
- Aspen stands are being encroached by conifers
- of various age classes leading to a decline in
aspen populations across the west. Aspen is also
a valued wildlife habitat component, and a
fire-resistant forest type.
Conifer removal and/or prescribed burning is
intended to reinvigorate aspen clones in the
project area.

Maintain a low risk fire area and stimulate aspen
in proposed unit 18.
Aspen regeneration surrounded by conifers in
proposed unit 29
16Forest Health
In areas where there are compelling reasons to
manage fuels or aspen, prescriptions would be
designed to help prevent mortality from insects
or disease, while meeting fuels and aspen
objectives.
When thinning this fuel break we propose to also
reduce the susceptibility of this stand to
mountain pine beetle. The white spots on the
tree trunk show active beetle hits.
Douglas Fir beetle mortality just north of
proposed units 31 and 32.
In recent years Douglas fir bark beetle have
killed a large percentage of the mature Douglas
fir trees in many of the drainages along the
shores of Hebgen Lake.
Opening the forest canopy through thinning has
been shown to reduce susceptibility of Douglas
Fir trees to bark beetle mortality. A similar
strategy is proposed in lodge pole pine forest
areas with recent mountain pine beetle attacks.
In stands with dwarf mistletoe infection, removal
of severely infected trees would improve the
health of the small trees and future
regeneration.
When treating this stand for ladder fuels we
propose to also remove the severely dwarf
mistletoe infected trees to improve the forest
health of regeneration.
17Desired Outcomes
This Douglas Fir forest was thinned to a similar
spacing as proposed in this project.
Prescribed burning in aspen clones can be used to
promote this type of aspen re-growth.
These fuel treatments in lodgepole pine are
similar to what we are proposing in this project.
