CHAPTER 1 – PURPOSE AND NEED
Introduction
The Forest Service has prepared this Environmental Assessment (EA) in compliance with the
National Environmental Policy Act (NEPA) and other relevant Federal and State laws and
regulations. This EA discloses the direct, indirect, and cumulative environmental impacts
that would result from implementation of the Walter Springs Project on the Cle Elum Ranger
District of the Okanogan-Wenatchee National Forest.
The EA is organized as follows:
Chapter 1 – Purpose and Need: This section includes background information about the
project, and describes the purpose of and need for action, and the agency’s proposal for
meeting purpose and need (alternative 2, the proposed action). It also describes how the
Forest Service informed other governments, other agencies, and the public about the
proposal, and how they responded. It lists issues raised during scoping, including
―unresolved conflicts‖ that are the basis for alternatives to the proposed action. For this
project, only one unresolved conflict emerged during scoping, therefore there is only one
alternative to the proposed action (alternative 3).
Chapter 2 – Alternatives and Required Mitigations: This section provides a more
detailed description of the proposed action (alternative 2) and alternative 3. It also
describes other alternatives considered but eliminated from detailed study, and lists
required mitigation measures for both action alternatives. It concludes with a table
displaying the differences between alternatives 2 and 3.
Chapter 3 - Environmental Consequences: This section describes the existing conditions
for each affected resource area, and environmental effects of the alternatives.
Chapter 4 - Agencies and Persons Consulted: This section documents other agencies
consulted during preparation of this EA, and lists the resource specialists involved in
preparation of the EA.
Chapter 5 - References
Appendices: Appendices provide additional detail to support various analyses and
findings within this EA. Appendices A, B, and C are attached to the EA. Other
appendices are included in a separate, stand-alone document.
Location and Setting
The Walter Springs Project Area is located approximately 9 miles south of the town of Cle
Elum in Kittitas County, Washington (Fig. 1, Vicinity Map). It encompasses 1,962 acres of
National Forest System Land located in the South Fork Manastash Creek subdrainage (Fig.1,
area shown in red). Elevations in the Project Area range from 4120 to 4840 feet. The legal
location of the Project Area is as follows:
Sections 14, 22-26, and 36, T. 18 N., R. 15 E., W.M.
The project planning area (2471 acres, Fig.1, area outlined in black) is bounded on
the east by the National Forest boundary, on the south in part by South Fork

Manastash Creek, and on the west and north by unnamed subwatershed boundaries. The Project Area may be accessed from the north on Forest Service Roads (FS Rds) 3300 and 3111, and from the south via FS Rd 3100.
There is one private inholding (509 ac) within the project planning area. Private land would not be treated under any alternative, and is not included in Project Area acreage.

The Project Area is not in an Inventoried Roadless Area, Proposed Wilderness Area, or
Wilderness Study Area1. It does not encompass or adjoin any Wild and Scenic Rivers.
It is heavily roaded—the current density of open system roads is 3.6 miles per square
mile. If closed roads with breached berms, unclassified roads on private land, and
unauthorized (user-built) roads are included in the road density calculation, then the
road density figure rises to more than 5 miles per square mile.
There is heavy year-round dispersed recreation in Manastash Creek watershed,
including camping, hiking, hunting, four-wheel drive motoring, motorcycle trail
riding, horseback riding, and snowmobiling. The Project Area encompasses 2.6 miles
of 4X4 jeep trail, but no single track motorized trail. It also encompasses 7.7 miles of
groomed snowmobile trail. All open system roads leading into and out of the Project
Area are groomed in winter.
Past and present management actions within and around the Project Area were
previously characterized in Taneum-Manastash Watershed Analysis (Cle Elum
Ranger District 1995). An updated list of management actions is presented at the
beginning of Chapter 3. There is a long history of timber harvest and domestic
livestock grazing within and around the Project Area. Though grazed by domestic
sheep, the Project Area is not classified as prime rangeland.
Regulatory Framework and Management Direction ___
Forest Planning
Under the National Forest Management Act (NFMA), all activities on National Forest System
Lands must be consistent with approved Forest Plans. In order to eliminate repetition and
focus on site-specific analysis, and consistent with 40 CFR 1502.20, this EA tiers to the Final
Environmental Impact Statement for the Wenatchee National Forest Land and Resource
Management Plan (USDA 1990, hereafter referred to as “Forest Plan 1990”), as amended
by the following documents:
Record of Decision for Amendments to Forest Service and Bureau of Land
Management Planning Documents within the Range of the Northern Spotted Owl and
Standards and Guidelines for Management of Habitat for Late-Successional and
Old-Growth Forest Related Species within the Range of the Northern Spotted Owl
(USDA and USDI 1994, hereafter referred to as ―1994 ROD‖). This decision
established the Northwest Forest Plan, and overlaid new land allocations (with a new
slate of standards and guidelines) on top of management areas from the 1990 Forest
Plan. It also adopted the Aquatic Conservation Strategy (ACS) as the principle
means of protecting and restoring aquatic ecosystems across watersheds.
Pacific Northwest Region Invasive Plant Program Preventing and Managing
Invasive Plants Record of Decision (USDA 2005). This decision added invasive
plant management direction to all Forest Plans in the Pacific Northwest Region. New
standards for invasive plant prevention and treatment are designed to protect human
health and the environment from the potential adverse effects of invasive plant
treatments involving herbicides.

Land Allocations
The two Northwest Forest Plan land allocations that overly the Walter Springs Project Area
are Matrix and Riparian Reserve (Fig 2). The network of Riparian Reserves adjoining
streams, wetlands, ponds, lakes, and other unstable or potentially unstable areas is a key
component of the ACS (1994 ROD pp. 7). In Riparian Reserves, riparian dependent
resources receive primary emphasis, and activities may not retard attainment of nine ACS
objectives listed in the 1994 ROD (pp. B-11).
Matrix lands are managed for ecologically diverse conditions and for commercial (and
sustainable) yields of wood (1994 ROD pp. B-6). Treatments in Matrix must retain moderate
levels of ecologically valuable old-growth components (such as snags, logs, and large green
trees) with at least 15% percent green tree retention (1994 ROD pp. C-40 – C-42).
Under the 1990 Forest Plan, two management areas—General Forest (GF) and Scenic Travel
– Partial Retention (ST-2)—comprise the Walter Springs Project Area (Fig. 3). The EW-2
management prescription also applies to unmapped Riparian Management Areas (RMAs) for
Class I, II, and fish-bearing Class III streams, ponds, and wetlands. ST-2 areas are managed
to retain or enhance the viewing and recreation experiences along scenic travel routes (Forest
Service roads and trails). GF land is managed primarily for commodity production. In
RMAs, management decisions must favor riparian dependent resources.
Standards and guidelines from the Northwest Forest Plan supersede those of the 1990 Forest
Plan unless the Forest Plan is more restrictive, or provides a greater benefit to late
successional species (1994 ROD pp. A-2). Applicable standards and guidelines from both
plans are described in Chapter 3.
Watershed Analysis
Watershed analysis—a systematic procedure to characterize the aquatic, riparian, and
terrestrial features within a watershed-- is another key component of the ACS (1994 ROD
pp. 10). The Taneum-Manastash Watershed Analysis was completed in 1995 and is
incorporated by reference into this EA. Its key findings in regard to vegetation included a
high risk of ―cataclysmic fire‖, high degree of natural variability, and extensive alteration of
riparian vegetation (including loss of snags and logs) due to previous and ongoing human
activities (road construction, danger tree management, timber harvest, grazing, and
dispersed recreation). The analysis also characterized the Manastash subdrainage as being
hydrologically unique and vulnerable, and having upper reaches that are important for water
storage and release. Streams were characterized as being deficient in large wood--and in
some places—shade, and as exhibiting high levels of sedimentation associated with roads,
trails, off-road driving, timber harvest, grazing, and recreational use. Road management
was listed as the single most important remedial action for wildlife habitat.
Forest Service Directives
The following directives influenced design of the Walter Springs Project:
Interim Management Direction for Retention of Large and Old Trees in Dry and Mesic
Forest Restoration Projects, Okanogan-Wenatchee National Forest, February 2010;
National Ecological Restoration and Resilience Direction (Forest Service Manual [FSM]
Interim Directive 2020.5, 08/30/2011).

The interim large tree direction requires retention of existing old trees in dry forest restoration
projects, unless a landscape level evaluation of forest condition has been completed to inform
development of harvest prescriptions. It lists minimum large tree retention objectives, by
forest type. The Walter Springs Project was already in the final stages of planning when this
direction was issued, but planned harvest and burning prescriptions were modified to conform
to this direction, by emphasizing retention of existing old trees and meeting or exceeding
minimum large tree objectives. A landscape level evaluation of forest condition has not been
completed for this watershed.
The Ecological Restoration and Resilience Direction requires managers to ―re-establish and
retain the ecological resilience of National Forest System Lands, through restoration
projects.‖ A healthy resilient landscape has a greater capacity to survive natural disturbances
and large-scale threats to sustainability (FSM 2020.2 pp. 8).
Other Federal Laws, Regulations, and Executive Orders
Resource-specific federal laws, regulations, policies, and Forest Plan direction are described
in Chapter 3, by affected resource area.
Other Supporting Analyses
Two roads analyses were considered during development of this project, as follows:
Okanogan and Wenatchee National Forest Roads Analysis (March 2004): This sub-
basin level road analysis process addressed Maintenance Level 3, 4, and 5 roads. The
objective was to review road status and road conditions, and identify a road system that
was safe and responsive to public needs and desires, affordable and efficiently managed
with minimal effects on other resource, and in balance with available funding for
maintenance and repairs. This interdisciplinary process considered the effects of roads
on biological, physical, and social resources, and assigned each road a priority for
keeping and maintaining or improving that road.
Road Analysis for the Walter Springs Project (Cle Elum RD 2010). This interdisciplinary
process expanded the 2004 roads analysis to include management level 1 and 2 (ML1 and
ML2) roads in the Walter Springs Project Area. Each road was assigned a management
recommendation (Project Record).
Both efforts were internal review processes that did not result in decisions about roads.
In the final year of planning for this project, consideration was also given to dramatically
declining budgets for road management, and an overarching need to reduce road maintenance
workloads. Minimum roads analysis has not been completed for this watershed.
Project Record
The Walter Springs Project Record includes Specialist Reports pertaining to Soils,
Hydrology, Silviculture (Forest Vegetation), Fire and Fuels, Botany, Aquatic Species,
Wildlife, Cultural Resources, Recreation, and Scenery. This EA incorporates by reference
the entire Project Record (40 CFR 1502.21), including all Specialist Reports and other
technical documentation used to support the analysis and conclusions in this EA. The
Project Record is located at the Cle Elum Ranger Station in Cle Elum, Washington.

Chapter 3 summarizes the various Specialist Reports, providing enough site-specific
information to demonstrate a reasoned consideration of the environmental impacts associated
with each alternative and how these impacts can be mitigated, without repeating detailed
analysis and background information available elsewhere in the Project Record.
Purpose and Need for Action
Ecological resilience is defined as ―the ability of an ecological system to absorb disturbance
while retaining the same basic structure and ways of functioning‖ (FSM Interim Directive
2020.5). Ecosystem functions include such processes as energy flow, nutrient cycling and
retention, soil development and retention, predation and herbivory and natural disturbances
such as wind, fire, and floods. All of these functions contribute to and sustain the
composition and structure of an ecosystem (FSM 2020.2).
Ecological resilience in the Walter Springs Project Area has been reduced in the following
ways:
Decades of fire suppression have altered stand and landscape level fuel conditions and
tree structure. Shade tolerant grand fir trees have become established in many
historically open stands on the slope above Manastash Creek, and in places, these grand
fir trees now form a dense intermediate forest layer that competes with older ―legacy‖
trees (Douglas-fir, western larch, and ponderosa pine) for water and nutrients. They also
provide a fuel ladder that can carry fire into the crowns of dominant older trees. Large
old trees which persisted for centuries under a regime of frequent low intensity ground
fires are now at risk of being injured and/or killed by crown fire.
Western larch is a fire dependent shade intolerant species. Mature larch is fading and
dying out of the overstory in many dense stands within Manastash watershed, mostly as a
function of age and dwarf mistletoe disease. In some stands, deepening shade and the
buildup of down wood, litter, and duff resulting from fire exclusion are preventing
regeneration of fire-adapted western larch and ponderosa pine trees. With dominant old
trees now at risk to crown fire and with conditions underneath these trees unsuitable for
seed germination, there is potential to lose the most genetically fit seed sources for future
stand regeneration following disturbance—the fire adapted species that persisted here for
centuries, prior to the era of fire suppression.
Regeneration of these long lived fire adapted species is critical to the restoration of dry
cool forest types that occur in the Eastern Cascade of Washington (Agee and Wright
2004).
Aspen is declining in this Project Area, due to advanced age and prolonged absence of
wildfire. Only a few small (<5 ac) patches persist, all located at the base of the south-
facing slope above South Fork Manastash Creek. All of these aspen patches are
comprised of 80-year-old-plus trees with many conks and cankers (indications of decay).
In all mapped clones (patches of genetically identical aspen), shade-tolerant grand fir
trees will soon overtop the surrounding aspen trees. The few aspen seedlings that grow
around the edges of these clones are heavily browsed by deer, elk, and domestic sheep
and are unlikely to grow to maturity. Therefore there is no aspen regeneration to replace
declining older trees.
From a landscape perspective, the prolonged absence of wildfire has also increased the
amount and continuity of surface and ladder fuels from stand to stand and in places, from
slope to slope. More specifically, there is less distinction between stands on dry
Environmental Assessment Walter Springs Project
9
southerly slopes, and stands growing on mesic north slopes and valley bottoms
(Watershed Analysis pp. 30). Because the historic vegetative mosaic here was
structurally diverse, fires historically burned at mixed intensities. Today’s landscape is at
risk to uncharacteristically large-scale disturbances from insects, disease, and/or high
intensity (stand-replacing) fire, due to the increased density of trees, and increased
continuity of surface and aerial fuels from stand to stand.
In places, previous reforestation practices have created unsustainable stand conditions.
Dense monoculture plantations of young ponderosa pine—some of it grown from seed
sources poorly suited to the area—occur here. These ―off-site‖ ponderosa pine trees are
growing poorly, and their stressed condition makes them highly vulnerable to insect and
disease attack, as well as fire.
Noxious weeds (primarily meadow knapweed and Canada thistle) have become widely
established along roads and on previously disturbed sites throughout the Project Area.
The risk of weed spread with any new disturbance is high. In places, weeds are
outcompeting desirable native vegetation. Invasive plants have low forage value for
wildlife, and at high densities, can affect rates of wildfire spread (Erickson and White
2007 pp. 2).
Off-road motor vehicle use associated with unauthorized roads and with long-term
dispersed camping along FS Rd 3111-115 is causing detrimental soil disturbance
(compaction and rutting) and loss of vegetation in meadows and Riparian Reserves.
Some unauthorized roads are being extended every year, creating more ―brown-out‖
(bare areas), more disruption of surface and groundwater flows, and increased risk of
noxious weed establishment and spread.
There is currently no security habitat for wildlife2 in the Walter Springs Project Area due
to high densities of open roads, 4X4 trails, ―user-built‖ (unauthorized) roads, and closed
Forest Service System roads that are being used, due to ineffective barricades. The area
is used by mule deer, elk, and their associated predators, but habitat effectiveness is low
here because of the high level of motorized disturbance. As a result, animals are being
displaced from potentially suitable habitats, disrupting the predation and herbivory
processes that are part of a healthy forest ecosystem (FSM 2020.5).
Desired Conditions
The desired landscape condition here is a mosaic of structurally diverse forest cover types
and ages reflecting variable topography and a propensity to burn at mixed fire intensities
(Watershed Analysis pp. 13-15, and 20). A structurally diverse landscape is less likely to
incur severe, large-scale disturbances and is therefore more ecologically resilient. Historic
conditions provide a proven model for sustainable and diverse forest conditions in the Walter
Springs Project Area, and also for the most effective ways to provide the required old growth
components in Matrix, as specified by the Northwest Forest Plan.
Open forest dominated by large old ponderosa pine, Douglas-fir, and western larch trees
would be the predominant feature on dry south slopes, with stringers of dense forest
providing shade over perennial and intermittent streams draining into South Fork Manastash
Creek. Patches of denser forest would also persist around and within scattered patches of
talus. Trees in upland forest would occur singly, in clumps with interwoven crowns and
occasionally in small, dense patches. Single legacy trees and unthinned patches with legacy
trees would be surrounded by gaps that protect them from fire.
areas free from motorized disturbance 2
Environmental Assessment Walter Springs Project
10
Stand structure would vary on mesic/moist north slopes and valley bottoms, and would
include some larger patches of dense, multi-layered old forest dominated by Douglas-fir and
grand fir, mid-seral forest dominated by western larch and Douglas-fir trees, and young forest
in both dense and open condition, with variably spaced young trees.
Aspen would comprise a discontinuous band on slopes adjacent to South Fork Manastash
Creek—at least some of it young and thriving. Aspen, shrub-dominated swales, riparian
forest, and meadows would contribute greatly to overall vegetative diversity in the Project
Area. Meadows would support native grasses, forbs, and shrubs, with no evidence of
compaction or rutting and brown-out due to unauthorized motorized travel, free of invasive
species. These areas would provide high quality forage for deer, elk, and domestic sheep.
Snags, logs, and other decayed wood habitat structure (trees with mistletoe brooms, dead
and/or broken tops, and other defects) would occur throughout the Project Area, in a range of
size and decay classes and in highly variable amounts. Snag and log densities would be
highest in riparian reserves and in dense stands on mesic north slopes and valley bottoms, and
lowest in dry upland areas and in stands adjacent to open roads (the latter due to ongoing
danger tree management and firewood collection). Snags and logs in advanced stages of
decay would reach their highest densities in riparian reserves and on shaded north slopes and
valley bottoms (natural fire refugia). Some dense patches of snags would also occur in
recently burned stands. A high percentage of the snags and logs in open stands would be
large (>20 inches in diameter at breast height). In upland forest, snags would occur singly, in
clumps, and within complex unthinned patches surrounded by open forest and/or gaps.
Purpose and Need for Action
Based on the differences between existing and desired conditions described above, and on
current management direction and guidance for the area, there is a need for greater structural
diversity within and between stands in the Walter Springs Project Area, including more open
forest areas dominated by large old trees (forest structure likely to burn at low intensity).
There is also a need for a broad mix of forest age classes here, including young stands
comprised of trees that are well adapted to each unique growing site, and dense old stands.
In South Fork Manastash Creek and its tributaries there is a need for cooler peak summer
water temperatures, therefore the Riparian Reserves here—particularly the inner gorges—
need dense ground cover and dense overstory vegetation. There is a need for reduced soil
disturbance along streams and in meadows, and for meadows that are fully vegetated with
native grasses, forbs, and shrubs, and devoid of weeds. There is a need for reduced
motorized disturbance to deer, elk, and wide-ranging carnivores in spring, summer, and fall.
Based on these needs, objectives for this project are as follows:
o In drier stands, reduce tree densities and surface and ladder fuel accumulations, and
restore historic species composition;
o Retain as many old trees as possible (i.e., trees established before the era of fire
suppression, regardless of their size). Old trees would be removed only for safety
and/or operational reasons;
o Retain large trees as indicated in Draft Interim Management Direction for Large and
Old Trees in Dry and Mesic Forest Restoration Projects, Okanogan-Wenatchee
National Forest, February 2010;
o Create open canopies and burned seed beds conducive to natural regeneration of
western larch and ponderosa pine (Fiedler and Lloyd 1992);
o Convert dense, poorly-growing ponderosa pine plantations to an appropriate mix of
species, with trees that are well adapted to these sites;
Environmental Assessment Walter Springs Project
11
o Regenerate decadent and declining aspen stands;
o Retain a mix of forest age classes across the Project Area, including some early, mid,
and late-successional forest areas. Also, retain a mix of open and dense forest
structure, consistent with aspect and historic stand structure;
o Retain all existing shade over perennial and intermittent streams;
o Provide for commercial removal of wood products;
o Re-introduce fire in an area long deprived of fire. Design burn plans to minimize
injury and mortality of large old trees, to preserve some dense forest stands on the
landscape, and to protect riparian features and functions.
o Reduce motorized disturbance to wildlife in and around treated stands, particularly in
areas where proposed thinning and burning will expose large expanses to views from
roads;
o Improve wildlife habitat effectiveness by obliterating unauthorized user-built roads,
and restoring effective closures on roads with failed berms and vandalized gates;
decompact soils and re-establish desirable vegetation on all restored sites.
o Control invasive plants in and around treatment areas and roads, and other areas
targeted for restoration.
Proposed Action
To meet purpose and need and move the Project Area towards the desired future condition,
the Forest Service proposes silvicultural treatments (harvest and prescribed burning) totaling
1654 acres (Fig. 4, Proposed Action). Treatments would include commercial timber harvest
(619 ac), precommercial thinning (17 ac), and natural fuels underburning outside of harvest
areas (1018 acres). After logging, all commercial harvest areas north of FS Rd 3100 would
be underburned along with the adjacent natural fuels areas, resulting in a more or less
contiguous ―first entry‖ burn totaling 1600 acres. A follow-up maintenance burn would be
implemented 5 to 10 years after the first entry burn.
During the first entry burn, an aspen regeneration area (29 ac) would be targeted for high
intensity burning, to kill the declining aspen overstory and stimulate new growth from roots.
After burning, a temporary elk-proof fence would be erected around at least part of the aspen
regeneration area to prevent grazing by deer, elk, and domestic sheep for 10-15 years. This
area would be excluded from follow-up maintenance burning.
Harvest activity would include commercial thinning (308 acres), long-term shelterwood
harvest (302 acres), and seed tree harvest (9 ac). Both ground-based and skyline logging
systems would be utilized, depending on slope and soil conditions (details in Chapter 2).
Winter logging would be required on most of the ground-based harvest acreage to prevent
detrimental soil disturbance, reduce risk of weed spread, and retain more understory
vegetation and logs to discourage off-road/off-trail motorized travel in treated stands.
Outside of Riparian Reserves, silvicultural objectives for all treatment areas would include
retaining a high percentage of the existing old and large trees, and maintaining or creating
more structural diversity within stands—a mix of single trees, clumps of trees whose crowns
intertwine, unthinned / unburned patches with snags and logs, and gaps. Within Riparian
Reserves, treatments would be designed to maintain all existing shade over water and a
higher average canopy closure throughout the Reserve, high densities of snags and logs, and a
high level of ground cover, particularly within inner gorge areas.
To facilitate timber harvest, six temporary roads totaling 1.4 miles would be required. All but
0.1 miles would be located on old skidtrails or old logging roads that would require little or

In addition, two closed Forest Service System Roads (3111-129 and 3111-131) totaling 0.4
miles, and one decommissioned road (near Stand J) totaling 0.4 miles in length, would be
reopened and used for timber sale access. The two closed roads currently receive
unauthorized use, with users driving around a failed gate. An effective closure (berm or gate)
would be restored following timber harvest. The decommissioned road used for harvest
access would be obliterated following harvest, and blocked with a more effective barricade
than exists now.
To mitigate the effects of thinning on wildlife, the proposed action also includes obliteration
of five unauthorized roads totaling 0.9 miles, and installation of more effective barricades on
four other ―closed‖ roads (also totaling 0.9 miles). None of these roads are needed for timber
sale access; therefore, these planned obliterations and closures would be undertaken
independent of the timber sale contract.
To further reduce motorized disturbance to wildlife (specifically, deer, elk and wide-ranging
carnivores) and to improve overall wildlife habitat effectiveness, an action is proposed that
would change the road’s management status. Approximately 1.7 miles of FS Road 3111-117
would be physically closed below Stand N, and its road maintenance level (ML) changed
from ML2 (suitable for high clearance vehicles) to ML1 (closed to vehicular use). The
closed section of road would be placed in a self-maintaining condition. A new gate or berm
would be installed at the point of closure.
The wet meadow between stands Q and S would be barricaded to prevent off-road motorized
travel, and restored by decompacting soils, treating weeds, and replanting barren areas with
native grasses and forbs. A heavily-used dispersed campsite on the meadow’s edge would be
relocated into adjacent trees, and the existing user-built access road would be shortened, so
that access to the dispersed campsite is on foot. Off-road travel would be curbed by placing
boulders at the meadow’s edge along FS Rd 3111-115 and along the shortened access road to
the campsite.
Connected Actions
Connected actions would include danger tree management along roads that would be used for
timber haul (approximately 19 miles), spot treatments with approved herbicides to prevent
and control invasive species on up to 200 acres per year for the life of the project plus 5
years, snow-plowing on all haul routes to facilitate timber harvest, and a two-year suspension
of sheep-grazing on the 1600-acre prescribed burn area, after the first entry prescribed burn.
The entire Project Area is located in the Manastash Sheep Allotment.
The proposed action and all required mitigations and design criteria needed to ensure Forest
Plan compliance, are described in greater detail in Chapter 2 of this EA.
Decision Framework
The Forest Supervisor for the Okanogan-Wenatchee National Forest will make the following
decisions based on the interdisciplinary analysis documented in this EA:
Whether to select the Proposed Action (as written or modified), or an alternative to
the Proposed Action (as written or modified);
What mitigation measures will be implemented with this project;
What monitoring efforts will be implemented with this project.

Public Involvement and Consultation
The project has been listed on the Okanogan-Wenatchee National Forest Schedule of
Proposed Actions since April 13, 2007. Letters describing the proposed action were mailed
on October 4, 2007 to tribal governments of the Yakama Indian Nation and the Confederated
Tribes of the Colville Indian Reservation, and to Kittitas County Commissioners. There was
no response from either tribal government or the county.
Letters were mailed to the general public and to other state and federal agencies (the Cle
Elum Ranger District mailing list) on December 26, 2007. We received comments from 6
individuals and/or organizations as a result of these scoping efforts.
The State Historic Preservation Office reviewed cultural reports and concurred with Forest
Service findings relating to this project on June 14, 2010. With planned mitigations, the
project will not affect heritage resources.
Pursuant to the Endangered Species Act, the District met with the U.S. Fish and Wildlife
Service (FWS) on May 6, 2010, for level I review of the draft Biological Assessment for the
Walter Springs Project. Informal and formal section 7 consultation with FWS was initiated
in June 2010. FWS concurred with Forest Service findings that proposed actions ―may affect
but would not likely adversely affect‖ both gray wolf and grizzly bear (Letter of Concurrence
dated June 16, 2010), and that the proposed action ―may adversely affect‖ the northern
spotted owl. In a Biological Opinion dated August 9, 2010, FWS concluded that the
Proposed Action would not likely jeopardize the continued existence of the northern spotted
owl.
In its Biological Opinion, FWS also made a number of recommendations regarding the
project, including monitoring needs.
The project will not affect anadromous fish, and consultation with the National Marine
Fisheries Service was not required. Nevertheless, information about the project was shared
with that agency, and no concerns were raised.
Issues
A list of issues was developed from public comments and from internal review of the
Proposed Action by the interdisciplinary team. Issues were divided into two categories:
those which can be addressed or resolved by incorporating design criteria, required standards
and guidelines, best management practices and/or other mitigations into the proposed action
(―non-significant issues‖, listed in Table 1), and those that can only be addressed by
developing an alternative to the proposed action (―unresolved conflicts‖).
Non-significant issues also include those which are outside the scope of the Proposed Action;
already decided by law, regulation, the Forest Plan, or other higher level decisions; irrelevant
to the decision being made; and/or conjectural and not supported by scientific or factual
evidence.
The only unresolved conflict that emerged from scoping concerned potential effects of
proposed treatments on the northern spotted owl, as follows:
Proposed thinning and burning in dense forest habitat would remove Nesting-Roosting-
Foraging (“NRF”) habitat for the northern spotted owl (a species listed as threatened
under the Endangered Species Act). The habitat that would be removed is located
within the potential home range area of an unoccupied spotted owl site – last used for
Environmental Assessment Walter Springs Project
15
nesting in 1989, and now occupied by barred owls. Because most of the available owl
habitat around this site remains intact, there is potential for spotted owls to reoccupy
this site if and when barred owls vacate the site. Removal of NRF habitat may preclude
future spotted owl reoccupancy of the site.
In response to this issue, alternative 3 was developed. Like the proposed action it would treat
to restore open conditions on dry, south-facing slopes, but would exclude most of the dense
forest areas that provide NRF habitat for spotted owls, from treatments. In this Project Area,
the majority (though not all) of the existing dense forest/owl habitat is located on north-facing
slopes and shaded valley bottoms. The unit of measure that would be used to address this
issue would be the acres of NRF habitat removed under both action alternatives.
Chapter 2 provides a more detailed description of the Proposed Action, as well as Alternative
3. It also lists required design criteria and mitigations for both alternatives, and a table
comparing the actions that each entails, and their environmental consequences. Detailed,
side-by-side maps of the two alternatives are located at the end of Chapter 2.
Appendix A provides additional details about the two action alternatives, in
tabular format.

of measure for tracking them throughout this document.
Issue Statement Rationale for Non-significance Unit of Measure
1. Smoke caused by burning activities has a potential to impact
the Ellensburg area. This may lead to narrow burn windows,
and delays in burning. Delays may increase fire risk from
untreated slash.
Burn plan would specify practices that effectively reduce
likelihood of smoke accumulation in Ellensburg. Planned
whole-tree yarding would limit logging slash, and thus help
minimize the amount of smoke produced.

produced’
2. Commercial logging has the potential to elevate fire risk, by
adding logging slash to fuel loads, and by opening up the forest
canopy and exposing both surface and aerial fuels to sun and
wind. Treated stands dry out faster, and are more likely to
ignite and burn.
Planned whole-tree yarding would effectively limit logging
slash, reducing the intensity of follow-up burns and natural fires.
Harvest prescriptions would emphasize retention of old trees that
prior to the era of fire suppression persisted and thrived under
open forest conditions with frequent low intensity fires. Even
though the rate of fire spread may increase in treated stands (due
to drying of fast-burning fuels), fire intensity and fire severity
would be reduced. The risk of uncharacteristic fire would be
reduced.

3. Noxious weeds already exist in some stands being considered
for treatment, and along most roads in the Project Area.
Disturbance from burning and logging would open the stand
and prepare the soil for invasive plant encroachment; it may
also stimulate germination of noxious weed seed already in the
soil.
Project would implement standards and guidelines from NWFP
Invasives ROD (2005) to reduce risk of noxious weed spread,
with pre- and post-treatment of problem weed areas, washing
and inspection of equipment, etc (BMPs).

6. Proposed thinning and burning may remove overstory
canopy along perennial streams, reducing shade and elevating
water temperatures. This may, in turn, reduce the quality of
fish habitat.
Would mitigate by adjusting unit boundaries and/or silvicultural

7. Proposed thinning and burning may reduce the percentages
of mature forest in areas with high cumulative effects from
previous harvest and roads. Additional removal of cover may
affect peak and baseflow discharge of streams. Altered peak
and baseflow may degrade channel conditions and reduce
quality of fish habitat.
Generally, treatments involving thinning and underburning of
predominantly open ponderosa pine stands do not measurably
increase peakflow discharges. BMPs to protect baseflows would
exclude groundwater discharge areas from treatments. Riparian
harvest and burning prescriptions would limit removal of
overstory canopy, to prevent changes in baseflows.

8. Logging practices may reduce effective ground cover and
increase surface soil erosion. This may result in increased
sediment delivery to streams, and reduced water quality.
BMPs for protecting soils, water quality, and inner gorge areas
would exclude equipment in sensitive soil types and inner gorge
areas. Riparian reserve prescriptions would ensure high retention
of effective ground cover within the Reserves. Planned
restoration of skidtrails, temporary roads, and landings would
include decompaction, seeding, and placement of wood to reduce
erosion.

9. Roads needed to implement proposed treatments (including
both system and unauthorized routes) affect hydrologic
processes, including flow regimes, water quality and stream
channel conditions.

construction and decommissioning would provide adequate
mitigation.

10. Proposed tree removal and underburning along trails and
roads would remove vegetation and down wood that now
discourages or prevents off-road/trail OHV travel. Skidtrails
that cross or connect to system roads and trails may also
encourage “pioneering” from these routes, and once tracks are
established, others users follow. These user-built trails often
result in soil erosion and increased sediment delivery to
Measures to reduce the likelihood of off-road/ off-trail use would
include recognition of high risk areas, adjusting skidtrail
locations so they are not visible from existing system trails and
roads, adjusting marking prescriptions along roads and trails to
retain more trees and logs, retaining roughness or native
vegetation on skidtrails, retaining more understory vegetation by
winter logging, and adjusting lighting strategies to strategically

13. Constructed firelines that intersect roads and trails look
like trails, and may encourage illegal OHV use.
Burn plan would limit fire intensity or exclude fire from areas of
concern to leave more vegetation. It would also include
provisions for strategically place wood and barriers (native
materials) during mop-up to camouflage constructed fire lines
near roads and trails. Firelines would not be tied into roads, until
immediately preceding burns.

14. Snow-plowing (associated with winter logging) would take
place on groomed snowmobile routes, displacing winter users
or reducing winter recreational use.
Timber sale contract provisions would require partial retention of
snow cover for snowmobilers on sides of plowed roads, and
would restrict winter logging and snowplowing during periods of
heavy recreational use (weekends). These measures have been
effective on other parts of the District.

Although the project would close 1.7 miles of open system road

16. Logging and burning activity may physically damage sites
eligible or potentially eligible for inclusion on the National
Register of Historic Places.
By law, all eligible and potentially eligible sites must be
protected from damage. Marking guides, unit boundaries, and
burn plans would be designed to buffer eligible sites from
physical disturbance, or to limit intensity of disturbance.

17. Proposed logging and burning operations may impede
sheep and herder access to foraging areas and approved
bedding grounds on the Taneum-Manastash allotment. There is
little or no opportunity to divert grazing to other locations or
allotments. May pose an economic hardship to the permittee.
Would mitigate by informing the permittee during annual pre-
turnout meetings where and when harvest and burning activities
may be occurring, and by adjusting the annual routing plan to
minimize conflicts.

18. For vegetation to recover after underburning, may need to
exclude treated areas from grazing for at least 1 year. May
pose an economic hardship to the permittee.
Would mitigate by giving permittee advance notice (at least one
year) that grazing activities would be suspended for at least two
years following treatments.

19. Appropriate funds for restoration and fuels reduction work
are limited and commercial removal of wood would help
finance accomplishment of restoration objectives. Planned
mitigations, however, may also reduce the net value of the sale,
and make it less attractive to buyers. If it does not sell, these
restoration needs would not be met.

20. Proposed thinning and burning would increase the amount
and quality of herbaceous forage for deer and elk, but in some
areas would also expose previously unseen areas to view from
roads. Distance to cover would increase for deer and elk using
treated stands, increasing their vulnerability to motorized
disturbance.
Project would effectively mitigate for increased vulnerability of
elk and deer to disturbance by closing both unauthorized and
system roads. Retention of denser cover in Riparian Reserves
and complex patches in upland treatment areas will also reduce
vulnerability of deer and elk.

21. Proposed aspen regeneration would create highly
preferred forage (tender new aspen growth) for elk, deer, and
domestic sheep. Aspen regeneration efforts may fail if grazing
cannot be excluded until seedlings reach at least sapling size.
Would mitigate this concern by erecting elk-proof fence around
regenerating aspen patches, and maintaining this fence for at
least 10 years following treatments.

22. Proposed construction and use of temporary roads, and
temporary use of closed roads may reduce security habitat and
increase motorized disturbance to elk and other wildlife.
Animals may be displaced from areas they now use.
Project would be designed to reduce effects from temporary
roads, by retaining patches of cover in treated stands and dense
cover within Riparian Reserves and by obliterating temporary
roads and reclosing system roads after treatments using the
timber sale contract (ensures timely closure). BMPs for effective
road closure would also be implemented, including dense use of
native materials to barricade road segments behind reconstructed
berms.
