    SCOPING NOTICE: CHIRICAHUA FIRESCAPE PROJECT

    Dear Friends and Neighbors of the Coronado National Forest:

    I am writing today to inform you about a fire management and fuel reduction project proposed

    for implementation on the Douglas Ranger District and adjacent lands in Cochise County,

    Arizona. The Forest Service, in collaboration with other Federal agencies, the State of Arizona,

    and private landowners, has planned the Chiricahua FireScape Project (Project) to improve

    fire management flexibility, efficiency, and consistency on approximately 500,000 acres of

    grassland, woodland, and forest in southeastern Arizona.

    The project area includes lands managed by the U.S. Department of Agriculture, Forest Service

    (Coronado National Forest); U.S. Department of the Interior, National Park Service (NPS-

    Chiricahua National Monument and Fort Bowie National Historic Site); U.S. Department of the

    Interior, Bureau of Land Management (BLM-Gila District/Safford Field Office); U.S. Fish and

    Wildlife Service (FWS-Leslie Canyon National Wildlife Refuge); State of Arizona; and private

    entities.

    The goals of the Project are to create a healthier vegetative landscape that would better survive

    wildland fire; enhance the protection of life, property, and natural resources from the potential

    adverse effects of wildland fire; and encourage naturally occurring wildland fire to function as a

    renewing process in the ecosystem.

    The Forest Service is acting as the Federal lead agency in the National Environmental Policy Act

    (NEPA) review of the proposed action. The NPS, BLM, and FWS are Federal cooperating

    agencies in the NEPA review, in accordance with regulations at 40 CFR 1501.6.

    The attached Scoping Notice was prepared by the lead and cooperating agencies to provide the

    public with a detailed description of the proposed action. Your comments on the scope of the

    NEPA review of the proposal, including those related to potential environmental issues and

    alternative means of accomplishing the project goals, are an important component of the

    environmental review process. Information on how and when to comment is provided below.

    PROJECT SUMMARY

    The Coronado National Forest (Forest) is leading the Chiricahua FireScape Project to coordinate Forest

    Service fire and fuels reduction activities with those of the National Park Service (NPS-Chiricahua

    National Monument and Fort Bowie National Historic Site), Bureau of Land Management (BLM-Gila

    District/Safford Field Office), Leslie Canyon National Wildlife Refuge, State of Arizona, and private land

    managers in the Chiricahua, Dos Cabezas, and Dragoon Mountains of Cochise County.

    Tree rings record centuries of regular fire in our grasslands, woodlands, and forests until the late 1800s.

    As we suppressed fires through much of the 20th century, fuels built up to unprecedented levels. Recent

    decades have seen wildfires burning through those fuels in southeastern Arizona produce effects more

    severe than was experienced historically. A 2010 analysis of fuels shows the potential remains for severe

    wildfire effects across much of the planning area; these effects have the potential to become even more

    severe under hotter, drier conditions.

    The Chiricahua FireScape Project is intended to reduce the costs, damage, and threats to safety from

    wildfires; sustain fire in fire-dependent ecosystems; maintain manageable fire behavior; and move

    vegetation toward a more “fire-resilient” condition. An interdisciplinary team will conduct an

    environmental effects analysis of alternative actions on ecological systems across jurisdictions. This

    approach aims to increase fire management flexibility, efficiency, and consistency across approximately

    500,000 acres of grasslands, woodlands, and forests. Proposed activities include prescribed fire, thinning,

    mechanical treatments, fuelwood harvesting, and some use of herbicides. These treatments are not

    uniformly applied across all ecological types but rather used singly or in combination as conditions

    dictate.

    The Chiricahua FireScape Project includes treatments within formally designated wilderness on BLM,

    Forest, and NPS lands. Active fire management is needed to preserve wilderness values (as defined by the

    Wilderness Act) that have been compromised by fire suppression. All treatments in all areas will be

    subject to sideboards designed to protect sensitive species, cultural sites, habitats, and developments. The

    Forest and BLM are soliciting your comments.

    BACKGROUND

    Geographic Location

    The proposed project area comprises three

    mountain ranges in southeastern Arizona:

    the Chiricahua, Dos Cabezas, and Dragoon

    Mountains (see Figure 1).

    The Chiricahua Mountains rise from

    grassland valley bottoms at elevations

    ranging from 4000 to 5000 feet to an

    elevation more than 9500 feet above mean

    sea level. Within the range is the Chiricahua

    Wilderness, which encompasses 87,700

    acres of high country. Chiricahua National

    Monument is located on the west side of the

    range and is surrounded on three sides by

    the Forest. Most of the 12,000-acre

    Monument is also designated as Wilderness.

    The Arizona Game and Fish Department

    manages a small tract east of the Monument.

    Private ranch lands sit at the base of the

    range and connect with the Leslie Canyon

    National Wildlife Refuge in the

    southwestern corner of the project area.

    Many of these ranches hold grazing permits

    on Forest and State of Arizona lands. The

    perimeter of the Chiricahua Mountains is

    sparsely settled, and eastside communities

    around Portal have the largest population

    adjacent to public land.

    The Dos Cabezas Mountains rise from 4000

    feet elevation on the valley floor to 7500

    feet and are contiguous with the Chiricahua

    Mountains. The Apache Pass fault is the

    formal boundary between the two ranges.

  • 2

    The BLM manages most of the Dos Cabezas

    Mountains, including 11,700 acres of

    designated Wilderness; private lands are

    dispersed throughout the range. Fort Bowie

    National Historic Site sits on 1000 acres that

    straddle Apache Pass; it is surrounded by

    BLM and Arizona State Trust lands.

    Neighboring private lands comprise ranches

    operated under BLM and State grazing

    permits.

    The Dragoon Mountains lie across the

    Sulphur Springs Valley to the west of the

    Chiricahua-Dos Cabezas complex. The

    range spans elevations ranging from 4600

    feet to 7519 feet on Mount Glenn. The

    Forest manages most of the range (54,000

    acres), which is surrounded by blocks of

    private and State land. The communities of

    Sunsites, Pearce, Dragoon, St. David, and

    Tombstone lie just beyond the base of the

    Dragoon Mountains.

    Fire and fuel management activities are

    proposed within congressionally designated

    Wilderness on BLM, Forest Service, and

    NPS lands. Active fire management is

    needed in these areas to preserve the

    “wilderness values” defined by the

    Wilderness Act of 1964 (Public Law 88-

    577). Past human activities, primarily fire

    suppression, bear much of the responsibility

    for the unhealthy vegetation and fuel

    conditions currently found on these lands.

    An ultimate goal of fire managers is to

    manage natural ignitions in Wilderness (i.e.,

    use naturally occurring wildland fire for

    resource benefits) to maintain wilderness

    values. Multiple treatments within

    Wilderness in the project area are

    anticipated to be needed before this tool can

    be safely applied.

    Existing Conditions

    An array of vegetation types is present

    across the various ownerships and

    jurisdictions in the project area, depending

    on elevation, topography, and geologic

    influences. For the purpose of project

    planning, these types have been designated

    as different “ecological systems.” Twelve

    distinct ecological systems are defined for

    the project area. Table 1 lists the proposed

    treatments in each system among the three

    mountain ranges depicted in Figures 2a, 2b,

    and 2c.

    Fire has played an important ecological role

    in the history of ecological systems in

    southeastern Arizona. A regular interval of

    naturally occurring fire restricts the growth

    of shrubs in grasslands, thins woodlands and

    forests of fire-intolerant trees, increases

    stream flows, and renews wildlife habitat.

    Historically, wildland fires in the woodlands

    and forests of southeastern Arizona have

    remained close to the ground surface,

    burned at low to moderate intensity, and

    maintained an open and grassy aspect.

    Fire history data recorded in tree rings show

    that since the beginning of the early 20th

    century, the frequency of natural fire has

    decreased dramatically. This decrease

    corresponds to an increased demand for

    wildland fire suppression to protect life and

    property and has led to areas of dense,

    overgrown vegetation that contributes to an

    abundance of fuel. Current conditions fuel

    wildland fires that eliminate desired

    ecosystem components, intensify the spread

    of unwanted non-native species, and result

    in dramatically different effects on

    watersheds than what would have occurred

    with the occurrence of natural fire. The

    28,000-acre Rattlesnake Fire that occurred

    in the Chiricahua Mountains in 1994

    illustrated the severe effects possible under

    such conditions.

    Based on the results of modeling using

    FlamMap, current fuel loadings across the

    project area are predicted to support severe

    effects, should a wildland fire occur. The

    model was run by the agency partners over a

    regional fuels map developed by the

    planning team. Model parameters were input

    for an elevation of 4500 feet, which was

    extrapolated to elevations above and below

    this level by FlamMap.

    Flame length is a good indicator of fire

    behavior and effects on the landscape. The

    red areas on Figure 3 depict locations where

    wildland fire in the project area, under the

    specified conditions, is predicted to spot,

    cause crown fires, and be very difficult to

    control. This sample model run is based on

    90th

    percentile weather and fuel conditions

    for southeastern Arizona. Using 97th

    percentile conditions observed during the

    large wildland fires of the past decades

    would turn additional areas on the map red,

    indicating flame lengths greater than 11 feet.

    WHY IS THIS PROJECT NEEDED?

    The need for this collaborative, cross-

    jurisdiction project derives from the various

    agencies’ respective missions to care for the

    land in accordance with direction and

    guidance in national, regional, and local fire

    planning documents. Fire management

    policy is complex, dynamic, and involves

    many layers of direction. Among the

    documents that have guided the

    development of the Chiricahua FireScape

    Project are the following:

    National Fire Plan of 2000;

    Guidance for Implementation of Federal Wildland Fire Management

    Policy (February 13, 2009);

    A Collaborative Approach for Reducing Wildland Fire Risks to

    Communities and the Environment:

    10-Year Comprehensive Strategy

    Implementation Plan (2001);

    Coronado National Forest Land and Resource Management Plan (Forest

    Plan,1986, as amended);

    Coronado National Forest Fire Management Plan (2009);

    Chiricahua National Monument Fire Management Plan (2005);

    Fort Bowie National Historic Site Fire Management Plan (2005);

    Fire Management Plan: San Bernardino and Leslie Canyon

    National Wildlife Refuges (2005);

    Bureau of Land Management Arizona Statewide Land Use Plan

    Amendment for Fire, Fuels and Air

    Quality Management (2004); and

    Bureau of Land Management, Dos Cabezas Mountains Wilderness

    Management Plan, Environmental

    Assessment, and Decision Record

    (June 1995).

    Collectively, these documents prescribe

    necessary changes in the landscape to foster

    the desired future conditions of an

    ecosystem in which the natural fire cycle

    prevails.

    Planning and implementation of pro-active

    fuel treatments toward the desired

    conditions of moderate fire behavior and

    restored ecological health is complicated by

    weather conditions, coordination of fire and

    vegetation management between multiple

  • 10

    Figure 3. Chiricahua Firescape Project: Predicted flame lengths assuming existing

    vegetation and fuel conditions in three mountain ranges in southeastern Arizona.

  • 11

    landowners, and the availability of funding.

    Thus, the primary purpose of this project is

    to integrate the fire and fuel management

    activities across 500,000 acres of Federal,

    State, and private lands to achieve the

    following objectives:

    reduce the costs, resource damage, and threats to public and firefighter

    safety from future wildland fires;

    restore and sustain ecological processes in fire-dependent

    ecosystems;

    create and maintain fuel conditions that produce manageable fire

    behavior and intensity; and

    alter existing vegetation and fuel conditions, as feasible, to approach

    those reflective of the historic range,

    both in the broader landscape and

    within individual ecological systems.

    PROPOSED ACTIVITIES

    The Chiricahua FireScape Project comprises

    a variety of fire and non-fire treatments that

    can be prioritized and scheduled by each

    agency’s fire and natural resources

    managers as conditions warrant. Each

    ecological system (Table 1) is proposed to

    be managed as conditions, funding, and

    resources allow. Implementation would

    adhere to stringent measures, referred to as

    design features, which have been designed

    to balance protection of resources

    achievement of programmatic goals.

    Table 1 displays proposed treatments in 12

    ecological systems over the three mountain

    ranges in the project area. Each proposed

    activity is defined by a prescription–a plan

    that describes what and how much

    vegetation should be manipulated; and a

    cost-efficient treatment –a method to

    achieve that prescription. In addition, each

    treatment will follow a silvicultural

    prescription –a set of instructions for

    proposed activities that would result in

    desired vegetation structure and

    composition; this is especially important for

    non-fire treatments.

    The treatment options listed in Table 1 may or may not be uniformly applied across those systems. For all fire-adapted systems, the goal of the project partners will be to allow fire to maintain these systems. As Figure 3 shows, much of the project landscape currently has the potential to burn and cause severe effects. In these areas, it may take multiple treatments to reduce flame lengths and move ecosystems toward desired conditions.

    An example of a multiple-entry treatment

    approach is that proposed for Rustler Park, a

    popular area in the Chiricahua Mountains

    managed by the Douglas Ranger District. A

    recent analysis outlined a path to reducing

    flame lengths in the mixed conifer forest to

    less than four feet under 90th

    percentile (hot,

    dry) conditions. For these dense, closed

    canopy stands, four steps were identified as

    being necessary:

    Hand thin trees less than 12 inches in diameter at breast height (dbh);

    Pile and burn slash;

    Pile and burn 90% of dead and down fuels; and

    Maintain conditions using prescribed fire.

    These steps would be executed at different

    scales (thinning and pile burning at small

    scale, prescribed fire at a larger scale) over a

    period of several years.

    This proposal to broaden the scale of fire

    management activities in the Chiricahua,

    Dragoon, and Dos Cabezas Mountains

    brings with it the responsibility to address

    multi-faceted concerns. The Project is being

    designed to apply best management

    practices that will ensure protection of

    sensitive natural and cultural resources and

  • 12

    neighboring developments. Agency

    managers will continue to collaborate and

    consult with communities, recreational

    users, permittees, researchers, and other

    parties who are stakeholders within the

    project area. This may include negotiating

    for flexibility in time and space to allow

    land managers to creatively take advantage

    of treatment opportunities, such as capturing

    a temporary funding opportunity, using a

    recent burn as a buffer, treating a

    temporarily vacant grazing allotment, or

    responding to a community request. In

    return, land managers would establish in

    advance the ground rules to protect values at

    risk, and protocols and schedules for

    monitoring treatments.

    With specific Project tools at their disposal,

    the project partners estimate annual

    accomplishments will include the

    application of prescribed fire on 6000 to

    40,000 acres; mechanical treatment of 1000

    to 3000 acres; and thinning of 200 to 500

    acres. Over time, multiple entries in various

    systems are likely to be needed to ensure

    that treatment prescriptions are met.

    Fire Treatments

    The following vegetation treatment and

    removal methods are proposed to be

    individually or collectively applied to

    achieve the wide range of goals specified in

    agency management plans. Treatments are

    designed to reduce surface fuels, ladder

    fuels, and/or the density of trees and shrubs.

    Weather, limited operating periods, and

    available funding will dictate the amount

    and type of treatment that might be applied

    in any given year.

    Prescribed Fire Any fire intentionally ignited by land

    managers in accordance with a regulatory-

    agency approved, site-specific “Burn Plan”

    and justified as necessary for the reasons

    below is considered to be a prescribed fire.

    The use of prescribed fire is justified to

    Reduce abnormally high fuel loads to begin to allow for a return to historic fire

    patterns and frequencies;

    Release nitrogen and other nutrients into the soil to support new plant growth;

    Encourage germination of various plant species. Many native plant and forest

    communities have adapted to fire for

    their germination and growth. Some

    species require seed contact with soil

    that is exposed by fire to naturally

    regenerate;

    Thin overcrowded forests. Thinned forests recover faster and are more

    resistant to insect and disease attacks.

    Currently, many of the mature forests in

    the project area are overcrowded,

    resulting in a lack of vigor and health;

    and/or

    Create vegetation diversity needed by wildlife. Wildlife, such as deer, benefit

    from new growth as plants produce more

    palatable browse/forage when re-

    sprouting after a fire.

    Prescribed fires are typically ignited by

    hand, mechanical or aerial firing methods

    and burn at low to moderate intensity over a

    predefined geographic area. Burn plans

    include, but are not limited to, a risk

    assessment that identifies hazards and

  • 13

    potential mitigating actions to protect life,

    property, and resources.

    Pile burning is a prescribed fire used to

    dispose of vegetation remaining after

    thinning and mechanical treatment. Pile

    burning is guided by burn plans that dictate

    burning parameters when conditions are

    favorable and the risk of fire spread is low.

    Trees, shrubs, pruned limbs, and dead and

    down woody material (generally larger than

    1 inch in diameter) are gathered and piled by

    hand. Piles may range from about five feet

    in diameter and four feet high to

    approximately 15 feet in diameter and eight

    feet high. They are carefully located to

    minimize scorch to the canopies and trunks

    of trees.

    Fire control lines confine prescribed fire

    operations within control perimeters (see

    Thinning below. Wherever feasible, control

    lines comprise natural features/barriers,

    including roads and trails. In some cases,

    however, construction of fire control lines

    may require cutting and clearing of

    vegetation.

    Non-Fire Treatments

    Thinning

    This treatment is accomplished using hand

    tools, chainsaws, or specialized mechanical

    equipment and creates a prescribed spacing

    among trees and shrubs. It is justified when

    it is needed to

    Serve as a fire surrogate to directly restore desired, healthier vegetative

    structure;

    Minimize the potential for unwanted wildland fires by reducing surface

    and ladder fuels and decreasing

    contiguous, abnormally heavy fuel

    loads; and/or

    Pre-treat areas to reduce fuels in a way that enables the subsequent safe

    and effective application of

    prescribed fire.

    Trees and shrubs would be selected for

    thinning based upon treatment objectives,

    tree-hazard ratings, snag recruitment, health

    and vigor, species, size, and age, in

    descending order of importance. The

    desired future condition for the ecological

    type determines species, size class, spacing,

    and residual stocking targets of thinning

    projects. Selective thinning favors retention

    of larger and older trees in uneven-aged

    stands and retention of the more fire-

    resistant species and sizes, while at the same

    time maintaining species diversity.

    Reduction of ladder fuels is generally an

    important treatment objective. Within zero

    to 300 feet from existing structures,

    vegetation treatments may be more intense

    than in areas further away.

    Construction of fire control lines may

    require the removal of herbaceous

  • 14

    vegetation, pruning, and/or cutting breaks in

    the fuel by hand and clearing all vegetation

    down to mineral soil. After fires are

    completed, rehabilitation may involve

    returning soil and woody material to the

    control lines, hand-constructing water

    diversion channels.

    In addition to rehabilitating a fire control

    line, other post-thinning activities may

    include

    removal of woody debris by hand or machine to an off-site location for other

    uses or burning.

    chipping of woody debris. The use of chipping is limited by the slope of the

    area. Chipped material may be

    dispersed over the treatment area and/or

    transported offsite for other uses.

    lopping and scattering, which disperses woody material on the ground to

    decrease fire intensity. Previously felled

    trees and shrubs are limbed, lopped, and

    bucked using chainsaws so that the

    resulting slash material lies closer to the

    ground surface (as opposed to creating

    burn piles). The slash material is then

    spread, more or less evenly, over the

    ground.

    pruning, which may be applied along major system road corridors, within

    fuelbreaks, or in conjunction with fire

    control lines to remove ladder fuels and

    facilitate prescribed burning. Using hand

    tools and chainsaws, tree branches are

    pruned as close to the bole as possible

    without damaging it. Trees are generally

    pruned no higher than 10 feet above

    ground level or one-third of the tree

    height, whichever is less.

    Mechanical Methods

    Mechanical treatments use machinery to

    reduce woody biomass across a larger area

    than is typically treated by thinning. The use

    of machinery is justified when it is

    necessary to:

    Address broad-scale invasion (generally into grasslands) of woody

    species that are difficult to control

    with fire or herbicides (for example,

    mesquite and juniper);

    Manage overabundant species that may germinate with fire and increase

    without frequent fire (for example,

    manzanita); and/or

    Treat wildland-urban interface (WUI) areas in some vegetation

    types.

    Mastication can be used to eliminate shrubs

    and small trees for ecological or fuel

    reduction purposes. Generally, a tracked or

    rubber-tired machine chops, shreds, and/or

    grinds small trees, limbs, shrubs, and dead

    woody debris into chips to be left on site.

    Mastication is feasible where slope angles

    are 40% or less. Mastication moderates fire

    behavior by reducing fuel-bed depths to

    generally less than six inches. Removal of

    target species encourages the growth of

    desired plants.

    Grubbing uses heavy equipment to fell

    and/or uproot trees that are encroaching on

    grassland. It may be followed by pile

    burning, salvage, or fuelwood harvesting.

  • 15

    Grubbing is no longer common on Federal

    lands because of the potential for adverse

    effects on areas that have archaeological

    significance.

    Application of Herbicides

    Application of herbicides following thinning

    and/or mechanical treatments is justified to

    Reduce re-sprouting of trees and shrubs to prevent re-growth; and/or

    Address broad-scale invasion (generally into grasslands) of woody

    species that are difficult to control

    with fire or mechanical means.

    Ground-based treatments use manual

    applicators or vehicles with spray booms.

    Strict buffer and grazing rest requirements

    would apply to broad-scale treatments.

    Herbicide applications would be scheduled

    and designed to minimize potential impacts

    on non-target plants and animals, while

    remaining consistent with the objectives of

    the vegetation treatment program. Rates of

    herbicide application would depend on the

    target species, presence and condition of non-

    target vegetation, soil type, depth to the water

    table, presence of other water sources, and

    the label requirements.

    Fuelwood Harvest

    Where terrain and access allow, certain tree

    species may be made available to the public

    for removal and use as firewood in order to

    Reduce fuels at little cost to land managers while benefitting end

    users; and/or

    Displace the harvest of other trees for firewood or raw materials in

    order to achieve a carbon-cycle

    benefit.

    Salvage of wood is governed by guidelines

    that protect surrounding resources and

    requires permits from the land management

    agency that manages the harvest, including

    cutting.

    Amendment of the Forest Plan

    To accomplish the proposed action, the

    Forest Plan must be amended to establish

    less restrictive Visual Quality Objectives

    (VQO) in the project area. Thus, the NEPA

    analysis would also evaluate the effects of

    amending the Forest Plan to change current

    visual quality standards and guidelines for

    the project area.

    Project Design Features

    Implementation of the Chiricahua FireScape

    Project will adhere to stringent design

    features that were developed to protect the

    inherent values and characteristics of native

    wildlife, plants, fish, and their habitats, and

    the soils, scenery, air quality, and historic

    and archaeological sites in each ecological

    system. As activities are proposed, fire and

    fuels managers will review treatment

    parameters to ensure that they are within the

    scope of the proposed action evaluated in

    this NEPA review and that they are

    consistent with the design features that

    bound them. Such prescreening will help to

    assess whether the effects of treatments fall

    within acceptable boundaries.

    Projects in the area will share many design

    features. Many of these will apply regardless

    of the presence of sensitive resources. In

    some cases, the need to protect life and

    property will override design features.

    General design features and the resources

    they will protect are as follows:

    To ensure safe fire operations: A

    prescribed “burn plan” will be developed

    and approved prior to initiating any burning

    operation, including burning of piles. A burn

    plan will include, but is not limited to, unit

    description, specific prescribed burn

  • 16

    objectives, public notification procedures,

    coordination with other regulatory agencies

    (such as air quality regulators), hazard

    analysis, contingency plan, firing

    procedures, risk assessment, mitigation

    measures, estimated fire behavior,

    acceptable weather variables, and prescribed

    burn organization.

    To maintain air quality: Fire managers

    will cooperate with other Federal, State, and

    local regulatory agencies to protect air

    quality as required by the Clean Air Act and

    State and local regulations.

    To minimize impacts of operations on the

    landscape: Off-road vehicle activity during

    fire activities in the Chiricahua, Dragoon,

    and Dos Cabezas mountains will be

    minimized. The creation of new access

    routes as needed for suppression activities

    will be limited and will avoid in designated

    Wilderness. These will be located only

    where other alternatives are not available.

    Areas of significant human activity during

    fire suppression operations, such as fire

    crew camps, landing strips, and equipment

    staging areas, will not be located on or next

    to sensitive resources or habitat of sensitive

    species.

    To prevent erosion, protect soils, and

    maintain water quality: Fire control lines

    on steep hillsides will be constructed in

    accordance with erosion prevention

    standards. Intense fire on sensitive soils,

    which may promote water repellency,

    nutrient leaching, and erosion, will be

    avoided. Burned areas will be rested from

    grazing for specified periods afterward.

    Riparian areas will be protected to prevent

    or minimize impacts to watersheds and the

    riparian habitat and species that occur there.

    Fire management treatments within or

    adjacent to riparian and aquatic habitats will

    be designed to provide long-term benefits to

    aquatic and riparian resources by reducing

    threats associated with dewatering and

    surface disturbance, and/or by improving the

    condition of the watershed and enhancing

    watershed function.

    To protect wildlife, fish, plants and their

    habitats: Specific protection measures will

    be implemented to protect and conserve

    wildlife, fish, plants, and their habitat. In

    addition, specific design features will protect

    the following special-status species: jaguar,

    lesser long-nosed bat, peregrine falcon,

    Mexican spotted owl, northern (Apache)

    goshawk, yellow-billed cuckoo, Chiricahua

    leopard frog, Yaqui chub, and Huachuca

    water umbel.

    To protect recreation uses and facilities:

    Project activities will be performed during

    low use periods. Slash and debris will be

    removed, impacted sites will be

    rehabilitated, and informational signs will be

    posted to advise users of potential conflicts.

    To protect scenic quality: Proposed

    treatments will be designed to blend with the

    natural environment as much as is practical.

    Specific instructions on techniques to reduce

    visual impacts will be implemented.

    To protect cultural and historic sites and

    resources: All historic and cultural sites will

    be surveyed, protected, and/or avoided.
