B-1

Appendix B: Design Criteria Common to All Alternatives The following design criteria are listed by resource area and do not suggest any particular order of priority. All activities proposed in this project would require implementation of these design criteria. In addition to this list, each of the action alternatives contain design criteria specific only to that alternative. The alternative-specific design criteria are located in Chapter 2 of this EIS under Alternative Descriptions.

Wildlife • The season of operations for prescribed burning will be limited to August 1 through May 1.

Guideline 5.4A-32051

• Activities will be allowed in all portions of the treatment area during the above season of operations. Guideline 5.4A-3206

2

• Harvest operations and road work within stands 030209-8 and 86 along Iron Creek would be completed within one operating season.

• Group selections up to 2 acres in size (four tree lengths) will be allowed. Guideline 21023

• When developing openings for forage production, copy naturally shaped edges. Guideline 2105

• Hinge all non-commercial conifers around and within hardwood release treatments, including inclusions, and directionally fall non-commercial conifers into the inclusion or around the perimeter to create a barrier. If non-commercial sized conifers are not available to create a barrier, mature aspen may be hinged around the perimeter in the same manner. Do not lop and scatter to the required 18-inch height, leave all slash as is to hinder browsing. After conifer treatment, a wildlife biologist and silviculturist will determine if prescribed burning is required to stimulate hardwood suckering.

• Design patch clearcuts to prolong forage production by designing them to be up to 10 acres in size. Guideline 2109 4

• Conserve live aspen with signs of cavity nesting where this will not conflict with clone regeneration. Guideline 2204

1 Guideline 5.4A-3205 was modified in an effort to provide opportunity for Springtime burning and still meet the habitat requirements of game animals and birds. The wildlife biologists from both agencies agree this is an appropriate modification to reduce the overall project length of mechanical and prescribed burning activity in the area. 2 Guideline 5.4A-3206 was modified. Wildlife biologists from both agencies agree simultaneous operations will not harm game animals and birds, though some may be temporarily displaced, and may be beneficial in reducing total time of disturbance in the area. About 50% of the entire project area will be treated. All treatments are not expected to occur at the same time, leaving ample escape areas including much of the Black Elk Wilderness, Grizzly, and Needles treatment areas. 3 Guideline 2102 was modified. Wildlife biologists from both agencies agree that this size of group selection will prolong the time these openings stay in Structural Stage 1, providing forage for game animals. The intent of these openings is to provide forage for game animals and create an uneven-aged structure for birds. 4 Guideline 2109 was modified. Wildlife biologists from both agencies agree this will prolong the time these patches stay in Structural Stage 1, and provide forage.


B-2

• Do not locate landings or slash piles in hardwood stands or inclusions unless no alternative sites are available. Do not locate skid trails in hardwood stands or inclusions unless and until all other options have been explored. When there is no option but to locate a skid trail in such a site, limit the number and length of skid trails to those that are necessary to accomplish objectives.

• Retain all snags greater than 20-inch dbh unless a safety hazard. If snag densities within a project area are below Objective 211, retain all snags unless they are a safety hazard. If large snags (>14” dbh) are not available, retain snags in the largest size class available. Standard 2301a.

• Retain at least six hardwood snags per acre in hardwood stands. Retain all snags in hardwood stands with snag density of less than six per acre. Standard 2301b.

• Cutting of standing dead trees for fuelwood is prohibited, except in designated areas. Standard 2304

• All soft snags should be retained unless they are a safety hazard. Standard 2305

• Activity debris will remain on site in all stands except those specified as “Whole Tree Yarding Required” under the Alternative descriptions Guideline 2307

• During vegetation management activities on ponderosa pine forested sites, retain an average of at least 50 linear feet per acre of coarse woody debris with a minimum diameter of 10 inches. On white spruce forested sites retain an average of at least 100 linear feet per acre of coarse woody debris with a minimum diameter of 10 inches. Standard 2308

• Any caves or mines discovered during sale layout, sale operations, or post sale layout will be reported to the District Wildlife Biologist and District Archaeologist for evaluation.

• Avoid ground disturbance within 100 feet of an opening to a natural cave. Standard 1401

• Avoid vegetative changes within 500 feet of caves or abandoned mines identified as being used as nurseries or hibernacula, unless needed to maintain bat habitat or if topography or other features protect the openings from disturbance. Slash shall not be piled at the entrance of caves or mines. Any caves or mines discovered during sale layout, sale operations, or post sale activities will be reported to the District Wildlife Biologist and District Archaeologist for evaluation. If determined that the site may be suitable bat maternity or hibernation habitat, buffers will be maintained to protect the microclimate of the site. Standard 3207

• Sites where a 500-foot no-activity buffer is required per Standard 3207— —

• Protect caves or mines identified as bat nurseries or hibernacula, and their microclimates when designing management activities (e.g. timber harvest, road construction, recreation facilities, trail construction). Protect known bat day and night roosts. Standard 3102

• Consider habitat needs (survey as appropriate) of regal fritillary and Atlantis fritillary butterflies prior to prescribed burning on prairies or meadows. This is especially important for prescribed burns scheduled from September through April. Design the project to conserve important habitat components of known sightings. Guideline 3105

• From April 1 to August 15, project activities that cause noise and disruption beyond that occurring at the time of nest initiation (e.g. road traffic, timber harvests, construction activities) will be prohibited within one-half mile of all active goshawk nests up until the nest has failed or fledglings have dispersed. Standard 3111

061703-39 061703-54


B-3

• A R2 sensitive species or species of local concern located after contract or permit issuance will be appropriately managed by active coordination between permittee, contractor or purchaser, Forest Service line officer, project administrator, and biologist/botanist. Solutions will be based on the circumstances of each new discovery and must consider the species need, contractual obligations and costs, and mitigation measures available at the time of discovery. Standard 3115

• In vegetation treatment units, leave one pile of woody material per 2 acres to create near-ground structure for small mammal species, except within 300 feet of buildings. If piles are created while accomplishing mechanical vegetation treatments, including mechanical fuel treatments, leave one pile per 2 acres for small mammal habitat. Approximate size of piles for this Standard is 10 feet x 10 feet and 6 feet in height. This does not apply to large piles resulting from whole tree harvesting. Standard 3117

• Manage known sensitive species and species of local concern snail colonies to:

a. Retain overstory sufficient to maintain moisture regimes, ground level temperatures and humidity.

b. Retain ground litter, especially deciduous litter.

c. Avoid burning, heavy grazing, off-highway vehicles (OHVs), heavy equipment and other activities that may compact soils or alter vegetation composition and ground cover.

d. If prescribed burning is unavoidable, burn when snails are hibernating, usually below 50 degrees Fahrenheit, and use fast-moving fires to minimize effects to snails.

e. Control invasive weeds, but use herbicides when snails are not on the surface, and treat individual plants rather than broadcast application. Standard 3103

• There is one sensitive snail site (061703-41) located along Willow Creek. Work should be done when the ground is frozen to prevent soil compaction and disturbance. Slash needs to be moved off this site for future disposal (i.e., burning or chipping). Standard 3103

• Treatments areas along riparian corridors and wet meadows will be limited to frozen ground conditions to protect leopard frog and song sparrow habitat. In particular, the Rabbit Gulch riparian site will be protected north from Highway 244 along riparian corridor for about 300 feet. Standard 3106

• Conserve live aspen with cavities. Standard 3124

• Provide big game screening along at least 20 percent of the edges of arterial and collector roads. Consider vegetation, slopes, landform, etc. in evaluating available screening. Guideline 32025

• Protect known raptor nests. Consider potential effects of disturbance, nesting phenology, human activities existing at onset of nest initiation, species, topography, other R2 sensitive species and plant species of local concern, forest cover, nest protection standards and recommendations used by state or federal agencies, and other appropriate factors when designing protection. One known historic raptor nest in 30302-6 will be protected by a 5-acre “no activity” buffer around this nest location. A newly discovered raptor nest, of unknown species, occurs in site 61703-16 and will also be deferred from treatment. Standard 3204

5 In the Norbeck project area, adequate screening is provided by landforms.


B-4

• Provide at least 2 to 6 turkey-roost sites per section, consisting of mature trees with an average diameter at breast height (dbh) of 10 to 14 inches, widely spaced horizontal branches, and basal areas at least 90 square feet per acre. Sites should be at least one-fourth acre in size and not isolated from adjacent forested stands. Emphasis should be on the upper third of east-facing slopes if available. Guideline 3205

• Throughout the Norbeck project area, willows greater than 6 feet tall will not be burned. Guideline 3210

• In areas identified as important connectivity corridors for marten, maintain canopy closure of at least 50 percent. Standard 3215

• In sites mechanically treated for the stand diversity habitat objective, retain all trees within a 30-foot radius of squirrel caches unless otherwise directed by a Wildlife Biologist.

• During prescribed burning lighting operations, do not apply fire directly to common juniper or squirrel caches

Fisheries • The discharge of dredged or fill material should not take place between October 15 and April

1 in coldwater streams, when water flow is present. Coldwater streams include: Battle Creek, Cabin Springs Creek, French Creek, Grizzly Bear Creek, Iron Creek, Lafferty Gulch and unnamed tributary, Palmer Gulch, Pine Creek and Sunday Gulch Creek. Consult the Fisheries Biologist for site-specific needs if this timing restriction is not practicable. Standard 1301

Botany • Habitat for R2 sensitive plant species and species of local concern will be protected from

mechanical disturbance. No new roads will be built through habitat of R2 sensitive and species of local concern.

• The district botanist will coordinate with the engineer to ensure the work done to closed road 356.1c will have the least impact possible on rare plant habitat.

• Habitat requirements of R2 sensitive plants and species of local concern will be considered when developing prescribed burn plans for areas with suitable habitat for these species. Small areas of known plant occurrences may be removed from the burn during burn plan development.

• Known noxious weed infestations will be treated with herbicides and biological controls after logging operations to reduce infestations and allow native vegetation to compete with non-natives. Areas will be treated again as necessary.

• Areas infested with noxious weeds may be treated with herbicide prior to disturbance to help reduce seed dispersal from existing plants.

• Disturbed areas such as skid trails, burned slash piles and temporary roads will be seeded with native species in seed/plant mixtures that are certified weed-free seed. Standard 1110

• To protect the riparian area and sensitive plants, there will be a 100-foot “no equipment” buffer in Stands 061703-02, 03 and 04. Site 061703-09 will also have a “no equipment” buffer which is 100-foot, or up to Forest Service Road 351. The east side of Forest road 351 may have machinery on it. This does not preclude felling of small diameter pine that may be hinged to provide shade and protection for the sensitive plants. No trees (>16” DBH) would be cut within the 100-foot stream buffer. Outside of the 100-foot buffer some large trees


B-5

would be left in these stands to address visual concerns and wildlife needs. These trees will be at least 16 inches DBH and will be marked by the wildlife biologist and the silviculturist.

• The district botanist will coordinate with the timber sale administrator to ensure sensitive species habitat (and individual plants) are protected during spruce enhancement treatments.

• Do not develop springs or seeps as water facilities where sensitive species or species of local concern exist unless development mitigates an existing risk. Standard 3104

• Riparian areas or wetlands, where populations of sensitive plants are located, should be protected during and after trail, road, and highway construction activities. Standard 3106

Fire and Fuels • Revegetation of prescribed burned areas will be promoted by:

a) Following broadcast burning, seed to initiate revegetation if ground cover is 60 percent or less and slopes are 30 percent or more.

b) If piled and burned fuel creates ash piles deeper than three inches, scatter the ash, scarify and mix it with mineral soil, or bury it. Guideline 4106

• Prescribed burn plans will identify acceptable levels of tree mortality for seedling/saplings, poles, and sawtimber; burning prescriptions will be established to meet these levels. Guideline 4108

• In the portion of Norbeck outside of the Black Elk Wilderness: Willows greater than 6 feet tall will not be burned. Acceptable mortality levels for mature oak, pine and spruce greater than or equal to 16 inches dbh is 10 percent. Guideline 4108

• All prescribed burn plans resulting from a decision on this project will be reviewed and approved by a District or Forest level Wildlife biologist and Botanist as part of the normal approval process.

• Slash piles that are scheduled for burning will be located outside of meadows that contribute to Waters of the United States. Use a buffer distance designed to keep sediment, ash and debris out of channels. Guideline 4111

• The threat of wildfire to public and private developments will be reduced by following standards in the National Fire Protection Association Publication 1144, “Protection of Life and Property from Wildfire” and reduce fuel loading from habitat improvement treatments to acceptable standards.

• All prescribed burn treatments will meet with the provisions of the Clean Air Act. District personnel would monitor burn conditions, and the SASEM (Smoke Model) or equivalent program would be used to assure provisions are met. The impacts of burning on metropolitan areas such as Rapid City would be assessed at the time of burning.

• Use Appropriate Suppression Response. Standard 4101

• Activity fuels will be treated along forest collector roads and forest development trails to meet the adopted SIO. Along arterial roads, remove 70-90 percent of activity fuels up to 300 feet from roads edge. Debris piles will be burned as soon as practical after remaining on-site


B-6

for at least 2 years6

• Conduct prescribed burning to minimize the residence time on the soil while meeting the burn objectives; this is usually done when the soil and duff are moist.

. Where mechanical treatment and prescribed burning is proposed within the same site, mechanical treatments will be completed prior to burning.

Heritage • All eligible and unevaluated sites will be avoided during project activities.

• If additional heritage resources are discovered during project activities, all operations will cease within a 30-meter radius of the site location and a District Archeologist notified immediately. Any heritage resources located during project implementation will be protected based on the recommendations of the District Archeologist and the SHPO.

Range • Fences will be built if natural barriers to livestock movement (e.g. dense tree growth) are

removed.

• Prescribed burning within the Palmer Gulch Allotment will require coordination with the grazing permit administrator. The fire burn boss for prescribed burning will need to know the grazing rotation for planning purposes. It will be critical for the grazing permit administrator to inform the burn boss of any changes in the rotation schedule as soon as possible.

• Prescribed burning will be limited to one unit per grazing system per burning season (grazing rotation schedules will be provided to the fuels planner as updated).

• Prescribed burning will occur prior to green-up in the spring or following curing in the fall.

• Prescribed burned areas will be deferred from livestock grazing for a portion or all of the following growing season to ensure regrowth of forage species. Guideline 4107

Recreation • Use of Forest Service System trails for hauling, skidding or other project related activities

will be restricted from May 15 to the day after Labor Day annually to avoid conflicts with three permitted outfitter and guide operations. These trails are:

Centennial Trail #89; Willow Creek Trail #8; Harney North Trail #9; Iron Creek Trail #15; Palmer Gulch KOA Permitted Trail – Willow Creek to Hay Draw

• During project activities, coordinate with the Boy Scouts of America (BSA) regarding their permitted Annual Pilgrimage (2nd week in September) which occurs within Norbeck on, portions of the Centennial trail #89, Iron Creek trail #15 and the Willow #8 and Willow-Rushmore #5.

• Any portions of Forest Service System trails used for hauling or skidding will be maintained to minimize erosion during use. Trails will be restored to improve tread and drainage following use to return the impacted area back to a trail design class. Trail reconditioning must be completed when ground is not frozen.

6 Guideline 4112 states that debris will be treated within 1 year of harvest completion, which generally allows for at least 2 years of drying time for piles. The 2-year timeframe for piles to be on-site prior to burning is added to insure piles are dry enough for successful treatment).


B-7

• Any trailheads impacted during implementation will be returned to pre-treatment conditions.

• Protect all trail improvements to include trailheads, wooden trail steps, wood water bars, fencing, signs and bridges when prescribed burning. Ensure trails are closed with adequate public notice, signed at trailheads and the area checked for any overnight backpackers before ignition begins. Closures of trails for prescribed fire should be long enough to allow cool down of the affected area and an opportunity for fire hazard tree assessment and removal if necessary to ensure public safety on trails.

• Logging slash in developed recreation areas will be either mechanically chipped or hauled to another area for later burning. Do not leave slash piles in developed campgrounds or other developed recreation sites.

• Safety signing will be placed in all appropriate locations including trailheads, main road intersections and recreation residence access roads, for the public to be warned of construction/logging activity and trucks hauling and will be consistent with Department of Transportation requirements.

• Willow creek campground and trailhead will be closed to public use during harvest operations (including hauling) at those sites. Public will be notified in advance of closure.

• Restrict logging activity in campgrounds and day-use sites during their primary season of use—from May 15th to the day after Labor Day, annually.

• Recreation sites that remain open all year should be closed for public safety during any logging operations with advanced media notices as well as on-site signage. These sites are Breezy Point Picnic Ground, Willow Creek Campground and Trailhead, Horsethief Lake Day Use Area and Wrinkled Rock Climbers Trailhead.

• Protect all developed recreation site improvements including parking lots, access roads, toilets, campsite furnishings, fences, horse water troughs, signing, etc. Ensure impacted sites are rehabilitated prior to the opening for public recreation on or about May 15th, annually.

• Coordinate with the 3 outfitter/guides permitted to operate within Norbeck.

• Access to recreation residences will be maintained during treatment activities, if possible. Residence owners will be notified of conflicts or closures that might occur.

• Protect all private property authorized under special use permit as part of the recreation residence program. This includes all off-lot improvements such as water spring boxes, water lines, fire pits and driveways.

• It is recommended that recreation residence roads maintained to a higher standard during the winter months for logging be signed as closed except to authorized use (this includes cabin owners and logging contractors).

Scenery • Locate log landings and un-merchantable material piles a minimum of 200 feet away from

US and State Highways whenever possible.

• Operations in all sites located within the Peter Norbeck Scenic Byway corridor (MA 4.2B) will be restricted to dry or frozen ground conditions to minimize soil disturbance. Where soil is displaced, re-contour to adjacent slope and seed with native grasses.

• The most current Black Hills NF “Visual Marking Guides” will be followed for unit layout and tree marking.


B-8

• Retain all the pine greater than 16 inches DBH within 100 feet of FSR 351 (Sunday Gulch road) to address visual concerns.

• Treatments within stand 061703-03 will retain some of the understory to provide a visual buffer adjacent to the Scenic Byway and the summer home groups.

• Retain all trees within 30 feet of US Highway 16A in site 093003-59 to retain the visual character and discourage vehicle access of this transitional meadow. Barrier rocks may be placed in site 093003-59 to discourage motorized access into the meadow.

• Hand-pile, chip or mulch activity fuels in the immediate foreground of US and State Highways, Scenic Byways, County Roads, Recreation Facilities, Recreation Trails, Wrinkled Rock Climbing Area, areas adjacent to Mount Rushmore National Memorial to limit additional disturbance to the area and clean up slash to natural levels. Guideline 5606

• Treatments around private land in forested areas should blend with the current condition on those lands where possible. Avoid creating strong lines between private and Forest Service boundaries. Remaining vegetation should be in a variety of sizes and spacing to maintain a more natural appearance. The transition zone width is dependent upon management and use of private land, as well as slope and variety of vegetation.

• Avoid creating geometric shapes when implementing proposed activities. Consider boundaries that follow vegetation types or sizes.

• When thinning dense stands, avoid creating a residual forested stand with evenly-spaced trees.

• Where possible along Highway 87, 89, 244 and 16A; remaining vegetation should be a variety of sizes and spacing to maintain a more natural appearance.

• All machine piles and decks where slash (tops, limbs) is burned: Rehabilitate (mix ash with unburned soil) and smooth after use to return to a natural-appearing, High Scenic Integrity condition. Place natural levels of down debris across the routes and re-seed7

• Clean up log decks within 300 feet of travel corridors by returning to original contours, scarify to eliminate compaction (as necessary), and plant with native grass seed.

.

• Remove un-merchantable material piles (‘cull decks’ and piles of tops/limbs) in the immediate foreground (300 feet) of the highways.

• Marking of the Free Selection treatments within Management Area 4.2B, Peter Norbeck Scenic Byway, will be coordinated and reviewed by a Forest landscape architect and silviculturist to insure scenery goals of maintaining large trees, creating uneven spacing and a variety of tree sizes are met.

Scenery Design Criteria for Specific Units Unit 061703-03: In this unit, retain some of the understory, including groups of 6-9” trees, to

provide a visual buffer adjacent to the Scenic Byway and the summer home groups.

Unit 061701-7: Clearcut: Treatments should blend from the created opening to the adjacent Unit 061701-36 and private land.

7 This is particularly important within the Byway corridor, around developed recreation areas (campgrounds and day use areas), non-motorized recreation areas (climbing areas), and along non-motorized trails.


B-9

Unit 030302-6: Variable Density 30 BA Treatment: Southern 1/3 of unit should retain groups of trees at 40-50 Basal Area to provide a visual blend from the open meadow to surrounding forest.

Unit 061701-40: Clearcut Treatment: Edge of opening should transition in vegetation density from surrounding forest to open area. Retain large trees adjacent to the lower-level overlook.

Unit 061701-41: Variable Density Thinning: Retain a 50 - 60 BA along the parking area and the accessible trail at Breezy Point, to maintain shade at the picnic area and provide a visual transition to the 40 BA in the rest of the unit.

Unit 061704-13: POL Treatment: Unit is adjacent to Horsethief Campground and the Centennial Trail. Leave basal area should be variable to create diversity.

Watershed • All applicable Best Management Practices (BMPs) and R2 Watershed Conservation Practices

(WCPs) will be implemented.

Water Influence Zone (WIZ) Design Criteria Protected stream courses have a Water Influence Zone (WIZ) which is 100 feet on either side of a stream (200 feet plus stream width). Activities can occur within WIZ areas with the following design criteria:

• Limit skid trails within the WIZ • Designate skid trails when in the WIZ • Avoid crossing perennial and intermittent streams to the extent practical • Avoid creating low-water crossings or 'fords' of streams. • Avoid skidding through water. Install temporary crossing structures to keep equipment

and logs out of water. • Rehabilitate forwarding and skid trail crossings of perennial and intermittent streams to

original contour and re-seed; install erosion-control matting for a distance of at least 25 feet from the stream on disturbed areas.

• Install drainage control structures on all forwarding and skid trails upon completion of work. When rehabilitated, discharge would flow through a filter of vegetation. Guidelines for spacing water bars (drainage control structures) is as follows:

Table B-1. Spacing for Water Bars Road or Trail Grade Spacing Between Water Bars

2 % 250 Feet 5 % 135 Feet 10 % 80 Feet 15 % 60 Feet 20 % 45 Feet

• Seed and brush any forwarding trail or skid trail within 50 feet of the stream course


B-10

Roads • Use erosion control devices at road crossings to minimize the amount of sediment

entering a stream. Some devices available include compost erosion socks or a sediment stop.

• Install seed and erosion control fabric for a distance of at least 25 feet from the stream on any disturbed areas upon rehabilitation of stream crossings

Protected Stream Courses • At a minimum, the following will be identified as protected stream courses: Pine Creek, Iron

Creek, Sunday Gulch, Battle Creek, Palmer Creek, Grizzly Bear Creek, Spokane Creek, Toll Gate Creek, Lost Cabin Creek, and the lower portions of Willow and Nelson Creeks (see Map 18 in Appendix A). Guideline 5.4A-1201

Low Organic Matter Design Criteria Soils that have low organic material in the top-soil require the following design criteria to maintain long-term soil productivity. These design criteria do not apply to areas adjacent to arterial and collector roads, trails, summer home groups and non-Forest System land.

• In sites identified as having low organic matter in the top-soil, and proposed for group-selection or variable density thinning to a 30 or 40 ba; retain 50 percent or more of fine logging slash (less than three (3) inches in diameter). See table B-6 for a list of sites where this applies.

• In sites identified as having low organic matter in the top-soil, and proposed for clearcut or group retention; retain 90 percent or more of fine logging slash (less than three (3) inches in diameter). See table B-7 for a list of sites where this applies.

Soil Compaction Design Criteria (see table B-12 for site list): “No Activity” - Soils with a Very High Erosion Hazard Rating (VHEHR), or soils with a high

mass-wasting potential on slopes greater than 40 percent. • No machinery operations will be allowed on slopes greater than 40 percent.

“Dry or Frozen” - Soils with a Very High Erosion Hazard Rating (VHEHR), or soils with a high mass-wasting potential on slopes 20 to 40 percent. • Machinery operations only permitted during dry or frozen conditions.

Mechanical site preparation must be restricted to dry soil conditions.


B-23

“Dry, Frozen or Low Impact” - Soils that are subject to compaction when wet • Machinery operations only permitted during dry or frozen conditions, or using

low-impact equipment (such as cut-to-length systems). Equipment operating on slash may be used with close monitoring. Mechanical site preparation must be restricted to dry soil conditions; OR, when soil is not dry, frozen or covered by compacted snow, skidders will remain on approved skid trails. Skid trails will average 100 feet apart center to center. Track-mounted felling equipment will be allowed to work off of approved skid trails. Trees will be “bunched” to allow skidders to reach them from approved skid trails.

Soil Heating • Conduct prescribed fires to minimize the residence time on the soil while meeting the burn

objectives. This is usually done when the soil and duff are moist.

Wilderness • The Wilderness boundary location will be maintained. Standard 1.1A-8101

Transportation • For all temporary non-Forest System roads, maximum clearing limit will be 12-feet-wide and

maximum running surface will be 10-feet-wide.

• Temporary roads will be limited to the bare minimum needed to accomplish habitat enhancements. Temporary roads will be rehabilitated as soon as possible after activities are completed. Rehabilitation will include scarifying, seeding, and slashing. Where temporary roads cross Forest System trails or occur adjacent to recreation residence lots or recreational developments, the temporary road would be slashed in for a distance of 100 feet where possible. Recontouring will be done where necessary to prevent erosion. An engineered road specification for road closures per C5.35# (Closure of temporary roads) may be required.

• Drainage structures (culverts) on temporary roads will be designed to the minimum standard necessary. Drainage structures will be removed following completion of project activities unless needed for recreational trail use.

• Current travel management gates will be maintained and kept closed by contractors and Forest Service personnel during habitat improvement activities. Gates must be closed after each passing and locked overnight and during other times of non-activity to avoid unauthorized access.


B-27

• When laying out vegetative treatment units, design unit boundaries to maintain the integrity and effectiveness of travel management gates.

• Landings and temporary roads will avoid locations requiring removal of pine and spruce greater than or equal to 20 inches dbh, as well as mature oak, birch and aspen, and squirrel caches whenever possible.

• Existing roads will be used rather than allowing new temporary roads, whenever feasible.

• Barrier rocks will be placed in site 093003-59 to discourage motorized access into the meadow.

• Road work necessary to implement alternatives must be completed in as short a timeframe as practical, to minimize impacts to wildlife.
