1.0 Introduction
1.1 Document Structure __________________________________
The Forest Service has prepared this Environmental Assessment (EA) in compliance with the
National Environmental Policy Act (NEPA) of 1969 and other relevant federal and state laws
and regulations. The EA is also required by Section 504(a) of The Rescission Act of 1995, which
directs the Forest Service to develop a schedule for the completion of NEPA analyses on existing
livestock grazing allotments. The direct, indirect, and cumulative environmental impacts that
would result from the proposed action and associated alternatives within the predetermined
analysis area boundary are disclosed in this document. The decision will be documented in a
Decision Notice and Finding of No Significant Impact accompanying the final EA after
receiving and considering public comment.
The document is organized into five parts:
Introduction: This chapter includes information on the history of the project proposal, the purpose of and need for the project, and the agency‟s proposal for achieving that purpose and
need. This section also details the acts, regulations, policies, and plans that frame the project,
and how the Forest Service informed the public of the proposal.
Alternatives: This chapter describes the different alternatives considered by the Forest Service for achieving the stated purpose and need of this analysis. Some of these alternatives
were studied in detail and others were dismissed from detailed analysis. The proposed action
was developed in response to significant issues raised by the public and other agencies, and is
discussed in more detail in this chapter. The chapter concludes with a summary table of the
environmental consequences associated with each alternative.
Environmental Consequences: This chapter describes the environmental effects of implementing the proposed action and other alternatives. This analysis is organized by the
significant issues raised by the public. Within each section, the affected environment is
described first, followed by the effects of the Current Management, Proposed Action, and No
Action-No Grazing Alternatives.
Consultation and Coordination: This section provides a list of preparers and agencies consulted during the development of the environmental assessment.
Appendices: This section provides more detailed information to support the analyses presented in the environmental assessment including public comments. Appendices are
included in a supplemental document.
Additional documentation, including more detailed analyses of project-area resources, may be
found in the project planning record located at the Los Padres National Forest (LPNF), Ojai
Ranger District Office in Ojai, California.
Lower Piru Rangelands Environmental Assessment
2 | P a g e
1.2 Background
The Lower Piru Rangelands (project area) are primarily on the Ojai Ranger District, LPNF near
Piru Reservoir in Ventura and Los Angeles Counties, California. The eastern portion of the
project area is within the Angeles National Forest (ANF); however the livestock grazing activity
in this portion is administered by the LPNF. The project area includes three grazing allotments:
the Piru, Pothole, and Temescal Allotments (Figures 1.2-1, 1.2-1a, 1.2-1b). These allotments
include private and National Forest System (NFS) lands creating a logical grazing area
promoting efficient use of intermingled land ownership.
The Piru Allotment is located on the LPNF and ANF in Canton Canyon northeast of Piru
Reservoir. The southeast portion of the allotment boundary follows the national forest
administrative boundary. The remaining allotment boundary lines meander along unsuitable
vegetation types and ridgelines that create effective barriers to livestock movement. The
allotment encompasses 3,495 total acres; 3,102 acres on NFS lands (2,679 acres administered by
LPNF), and 393 acres on private lands (Table 1.2-1).
The Pothole Allotment is located northwest of Piru Reservoir and is divided into two units: the
Pothole and Lisk Units. The Pothole Unit is located northwest of the Lisk Unit and within the
Sespe Wilderness. The Lisk Unit includes a small piece of wilderness and a large portion of
United Water Conservation District (UWCD) lands. The Pothole Unit includes 933 acres (all
NFS lands) and the Lisk Unit encompasses 2,785 total acres; 2,204 acres on NFS lands, and 581
acres on private (mostly UWCD) lands (Table 1.2-1).
The Temescal Allotment is located west of Piru Reservoir and is divided into two units:
Reasoner and Rodeo Flat Units. The Reasoner Unit is located within Reasoner Canyon and the
lower half of Dominquez Canyon. The Rodeo Flat Unit is located in the upper half of
Dominquez Canyon west of the Reasoner Unit and is partially within the Sespe Wilderness and
Sespe Condor Sanctuary. The Temescal Allotment encompasses 3,682 total acres; 2,916 acres
on NFS lands, and 766 acres on private lands (Table 1.2-1).

Allotment and unit boundaries are a combination of fence lines, natural barriers, watershed
boundaries, and other lines such as administrative boundaries and section lines. They represent
the extent of authorized livestock grazing. All lands within the allotment and unit boundaries are
considered part of the allotment or unit regardless of ownership. For these types of allotments,

the Forest Service issues term grazing permits with provisions that account for the percentage of
private grazing acres.

History
Livestock grazing occurred on lands part of the LPNF prior to establishment of the NFS in 1891
(USDA-FS 2005e, pg. 289). Within the project area livestock grazing dates back to the 1880‟s
(King 2011). Improvements, including fences, water developments, roads and trails, were
constructed and used to support the management of livestock and the rangeland. The roads and
trails were authorized in accordance with the terms and conditions of term grazing permits issued
by the Forest Service. These permits required the permittee to maintain and repair
improvements, including roads and trails. Over time, some of these roads and trails have
returned to natural conditions as a result of non-use.
During the past thirty years, authorized livestock grazing and associated improvements in the
project area has remained fairly constant. Two livestock grazing operators have each been
issued separate term grazing permits for the project area on a recurring basis. One permit
authorized livestock grazing on the Piru, Pothole, and Temescal (Reasoner Unit) Allotments.
The second permit authorized grazing on the Temescal Allotment (Rodeo Flat Unit).
Since the late 1970‟s, management of the Piru and Pothole Allotments was conducted in
conjunction with a grazing permit issued by UWCD to the same permittee. The permittee grazed
livestock and managed the Forest Service, private, and UWCD lands together as one
management unit.
In 2002, the Forest Service re-issued two term grazing permits for the three grazing allotments.
Subsequently, following the issuance of these term grazing permits, the UWCD informed the
permittee that the grazing lease would be discontinued due to conflicts with visitor use and
endangered species concerns. This had an impact on management of the Piru and Pothole
grazing allotments on NFS lands. These changes meant the Forest Service needed to prevent
livestock from entering UWCD lands to restrict the livestock from accessing endangered species
habitat both on UWCD and NFS lands. In order for the Forest Service to meet its obligations
under the Endangered Species Act, a change was made to the 2002 permit for the Piru and
Pothole Allotments.
In response, the Forest Service determined that the adjacent Pothole and Piru Allotments should
be rested from continued livestock grazing until an environmental analysis could be completed to
evaluate the effects of reinitiating livestock grazing on those allotments. Subsequently, the term
grazing permits were amended to reflect this change in authorized use. Since then, livestock use
and allotment management in the project area has only been authorized for the Temescal
Allotment. Upon expiration of both term permits in 2008 and 2011 respectively, temporary one-
year grazing permits have been issued for the Reasoner and Rodeo Flat Units of the Temescal
Allotment.

1.3 Purpose and Need for Action __________________________
Purpose
The purpose of this action is to determine whether to authorize livestock grazing on all, some
portion, or none of the Piru, Pothole, and Temescal Allotments.
Need
The overall need is to ensure that livestock grazing is managed in a manner that moves towards
desired resource conditions consistent with multiple use goals within the 2005 Los Padres
National Forest Land Management Plan (Forest Plan). Specifically, there is a need to:
1. Comply with Forest Service policy (FSM 2203.1) to make forage available to qualified livestock operators that are suitable for livestock grazing consistent with the Forest
Plan.
The Forest Plan provides direction to maintain sustainable grazing opportunities on healthy
rangelands, with fully functional and productive watershed conditions (USDA-FS 2005a, pp.
42-43 & USDA-FS 2005b, pg. 141). Field investigations contained in the project record
demonstrate that areas currently being grazed are meeting or moving towards desired
conditions. Additionally, small ranches permitted to use allotments have historically relied
on forage provided by Forest Service rangelands in the Piru, Pothole, and Temescal
Allotments for viable ranch operations.
2. Mitigate livestock grazing impacts to threatened and endangered species habitats at
specified locations.
According to the Forest Plan Goal 5.2, the desired condition for riparian condition is that
watercourses are functioning properly and support healthy populations of native and desired
nonnative riparian dependent species (USDA-FS 2005a, pg. 41). The Forest Plan also states
to provide ecological conditions to sustain viable populations of native and desired nonnative
species (Goal 6.2) (USDA-FS 2005a, pg. 44). In 2003, livestock were removed from the Piru
and Pothole Allotments to mitigate impacts to species habitat in certain riparian areas until an
environmental analysis could be completed to evaluate the effects of reinitiating livestock
grazing. Prior to 2003, livestock were entering riparian areas on United Water Conservation
District (UWCD) lands immediately west and north of Piru Reservoir (SBBM, T 5N, R 18W,
Sections 15 and 22) where the endangered arroyo toad and southwestern willow flycatcher,
and federally designated critical habitat exists. Since then, areas north of Piru Reservoir have
also been listed as federally designated critical habitat for the threatened California red-
legged frog. In addition, within certain areas of Reasoner Creek (SBBM, T 5N, R 18W,
Sections 20, 28, 29, & 33) there is a need to protect flycatcher riparian habitat, which prior to
the 2005 flood event was suitable habitat for southwestern willow flycatcher as well as other
riparian dependent wildlife.

3. Determine the suitability of roads in Wilderness and Inventoried Roadless Area (IRA) that provide access within the allotments for management.
A network of non-system roads has been used historically to access and manage livestock
grazing on the allotments. However, the use and maintenance of these roads have not been
evaluated as to whether they are compatible with Wilderness (FSM 2320) and Inventoried
Roadless Area (CFR 294) policy and regulations. Roads are needed to manage the allotment,
including the ingress and egress of livestock, access to range improvements, and to complete
allotment monitoring. The current authorized road network needs to be evaluated for
continued use and maintenance.
4. Prevent livestock from trespassing onto UWCD lands and impacting recreation in the Lake Piru Recreation Area.
Historic grazing permits for the Piru and Pothole Allotments included lands administered by
the UWCD. In 2002, the UWCD informed the permittee that the grazing lease would be
discontinued on their lands due to recreation and resource concerns. To mitigate the
potential of livestock roaming onto adjacent UWCD lands in the Piru and Pothole
Allotments, the Forest Service removed livestock from these two allotments until an
environmental analysis could be completed.
1.4 Proposed Action _____________________________________
The LPNF proposes to authorize livestock grazing on suitable NFS lands within the Piru, Pothole
(Lisk and Pothole Units), and Temescal (Reasoner and Rodeo Flat Units) Range Allotments.
The proposed action is the result of extensive analysis and consultation with interested
individuals and groups over the last nine years, and meets the purpose and need.
The proposed action incorporates adaptive management principles. Adaptive management is a
process that allows the Forest Service officer in charge the flexibility to respond to changing
conditions over time within bounds set by this NEPA analysis. Considering the extended
timeframe of a typical Term Grazing Permit (10 years), management flexibility is important to
respond to changing environmental conditions from one year to the next.
The proposed action includes a monitoring plan to determine whether actions are being
implemented as planned, and if so, if adequate progress toward desired conditions is being
attained. Monitoring information would inform management of the allotment and identify any
deficiencies that need adjustment or change within the scope of the effects analyzed in this
document. A full description of the proposed action is in Chapter 2 of this document.
1.5 Management Direction ________________________________
National forest management is guided by laws, regulations, and policies that provide the
framework for all levels of planning. This includes regional guides, the Forest Plan, and site-
specific planning documents such as this EA. By tiering this project to the Forest Plan, it is
expected that all applicable federal, state, or local laws would be met.
Lower Piru Rangelands Environmental Assessment
10 | P a g e
Law
Congress intends to allow grazing on suitable lands where it is consistent with other multiple use
goals and objectives as provided through several Congressional Acts: Multiple Use Sustained
Yield Act of 1960, Wilderness Act of 1964, Wild and Scenic Rivers Act of 1968, Forest and
Rangeland Renewable Resources Planning Act of 1974, Federal Land Policy and Management
Act of 1976, and National Forest Management Act of 1976.
Regulations and Policies
It is Forest Service policy to make forage available to qualified livestock operators from lands
that are suitable for livestock grazing consistent with land management plans (36 CFR 222.2(c);
FSM 2203.1). Term grazing permits are generally issued for ten-year periods (FSM 2203.1).
Forest Plan
The Forest Plan provides guidance for all management activities, establishes management
standards and guidelines, and describes resource management practices (availability and
suitability of lands for resource management). Additionally, the Forest Plan provides the
framework to guide resource management operations of the forest, and subsequent land and
resource management decisions made during project planning. The National Forest Management
Act of 1976 requires that resource plans, permits, contracts, and other instruments issued for the
use and occupancy of federal lands be consistent with the Forest Plan. Site-specific project
decisions must be consistent with the Forest Plan, unless the Forest Plan is modified with an
amendment. This EA is a project-level analysis and evaluates the proposed action‟s
conformance with the Forest Plan.
The project area is primarily within the Ojai-Piru Front Country Place, for which the desired
condition is a naturally appearing landscape that serves as a high-quality recreation area and
scenic backdrop to nearby communities (USDA-FS 2005b, pg. 70). The Pothole Unit and the
western part of Rodeo Flat Unit are in the Sespe Place. The desired condition for the Sespe
Place is a naturally evolving landscape providing primitive recreation opportunities (USDA-FS
2005b, pg. 83). Livestock grazing is a recognized use in these two Forest Plan designations
(USDA-FS 2005b, pp. 69 & 82).
A description of the Forest Plan goals and standards considered in the analysis can be found in
Appendix A.
Suitable Lands
The Forest Plan determined that the Piru, Pothole, and Temescal Allotments are suitable. As
outlined in the Forest Plan, an interdisciplinary team (IDT) completed range analysis to verify
site specific capability and suitability of livestock grazing on these allotments (USDA-FS 2005c,
Appendix J). Rangeland capability represents the biophysical determination of those areas of
land that can sustain domestic livestock grazing. Suitable rangelands are a subset of capable
rangelands where livestock use is found to be compatible with other uses: ecological, social, and
Lower Piru Rangelands Environmental Assessment
11 | P a g e
economic considerations and the ability to meet or move toward Forest Plan desired conditions.
Permitted livestock numbers are dependent on the acreage and forage production of suitable
rangelands.
Table 1.5.-1. Suitable acres of the Lower Piru Rangelands under current management in the project area. The percentage of NFS lands that have suitable rangelands is shown.
Allotment (Unit) Total NFS
Acres NFS Suitable
Acres % NFS Suitable
Piru 3102 490 16
Pothole (Lisk) 2204 507 23
Pothole (Pothole) 933 184 20
Temescal (Reasoner) 1824 574 31
Temescal (Rodeo Flats) 1092 379 35
Suitable rangelands are further divided into primary and secondary range. Primary range is
easily accessible and contains high forage value and palatability in comparison to the rest of the
allotment‟s vegetation. The secondary range terrain is steeper making it less desirable or
accessible by livestock and contains lower forage value and palatability of vegetation than
primary areas.
1.6 Decision Framework
The EA discloses the environmental consequences of implementing the proposed action and
alternatives to that action. The responsible official will review the EA and make a decision
whether to authorize grazing on the Piru, Pothole (Lisk and Pothole Units), and Temescal
(Reasoner and Rodeo Flat Units) Range Allotments. A separate Decision Notice and Finding of
No Significant Impact, signed by the responsible official, will explain the management and
environmental rationale for selecting an alternative to be implemented. If a decision is made to
authorize grazing, then Term Grazing Permits, Allotment Management Plans, and Annual
Operating Instructions will be issued in compliance with the decision.
1.7 Public Involvement __________________________________
Several methods were used to solicit comments from members of the public, agencies, tribes,
permittees, adjacent property owners, and organizations. The project was listed in the LPNF
Schedule of Proposed Actions (SOPA) prior to 2003 through 2011. A scoping letter was mailed
to potentially interested members of the public, adjacent land owners, tribal representatives,
organizations and other public agencies on June 2, 2003. More recently, the document was
subject to a formal 30-day notice and comment period, which occurred August 28 to September
28, 2009. A second 30-day notice and comment period was provided on September 2, 2010, to
allow for full disclosure after the Rodeo Flat Unit boundary was adjusted to include a previously
omitted wilderness area. All comments from scoping and formal comment notices have been
analyzed and answered as appropriate either in the document or by direct response.

A list of individuals and groups who submitted specific comments throughout the project
planning process, their comments, and Forest Service consideration of comments is summarized
in Appendix E.
1.8 Issues _____________________________________________
Through a series of meetings and conference calls, the IDT reviewed comments received during
scoping and public involvement efforts. Public comments were used to identify potential issues.
The following is a description of issues identified by the IDT for the project area.
Issue 1 - Water and Soils: Livestock grazing has the potential to affect water quality and
introduce fecal coliform and cryptosporidium into Piru Reservoir. Livestock grazing also has the
potential to affect soil porosity and soil density leading to increase soil erosion. This issue is
addressed in Section 3.1 of this EA.
Issue 2 - Threatened, Endangered, Sensitive, Management Indicator, and Migratory Bird
Species: Livestock grazing and associated road use and maintenance can affect national forest
plant and animal species and species federally listed as threatened and endangered and their
critical habitats, including the California condor, California red-legged frog, arroyo toad, and
southwestern willow flycatcher. This issue is addressed in Section 3.2 of this EA and in the
Biological Evaluation (BE) and Biological Assessment (BA) for this project. (See project record)
Issue 3 - Cultural Sites: Livestock grazing and range improvements have the potential to affect
historic and traditional cultural properties, and may conflict with cultural values held in regard
by Native American and other ethnic groups. This issue is addressed in Section 3.3 of the EA.
Issue 4 - Noxious and Invasive Weeds: Localized heavy grazing can reduce foliage density and
increase the amount of bare ground, thereby creating sites available to non-native invasive
species. The amount of vegetation (forage) removed can affect plant species diversity. This
issue is addressed in Section 3.4 of the EA.
Issue 5 - Recreation: Proposed fence improvements may impact visual quality from Blue Point
landmark and livestock grazing may impact recreation on the Pothole Trail. This issue is
addressed in Section 3.5 of the EA.
Issue 6-Special Designation Areas: Livestock grazing and roads may impact values and
characteristics associated with the Sespe Wilderness, Sespe Condor Sanctuary, Sespe-Frazier
Inventoried Roadless Area (SFIRA), and Wild and Scenic River. This issue is addressed in
Section 3.6 of the EA.

2.0 Alternatives
This chapter describes the three alternatives considered for the Lower Piru Rangelands Project.
The interdisciplinary team considered the following elements when developing the alternatives
for this analysis: public scoping and internal review by the Forest Service; the purpose and need
for this project; responsiveness to issues as identified in Chapter 1; site-specific resource
information; and acts, regulations, policies, and plans governing land management on National
Forest System lands. An alternative comparison is displayed in Table 2.3-1 of this chapter.
2.1 Alternatives Studied in Detail __________________________
Alternative 1 – Current Management
The allotments would continue to be authorized and managed in accordance with the current
permitted use, which only authorizes livestock grazing on the Temescal Allotment. Livestock
grazing is not authorized on the Piru and Pothole Allotments and the allotments would be
designated as vacant. The range improvements within the Piru and Pothole Allotments would
not be authorized for use by a term grazing permit (Figure 2.1-1).

Livestock Grazing
The Temescal Allotment consists of suitable rangelands both on NFS lands and private lands that
would be grazed as one continuous area. NFS lands would be administered by the Forest
Service, and non-NFS lands administered by the private land owner. With this alternative the
permittee would be permitted to graze livestock numbers displayed in Table 2.1-1.
Table 2.1-1. Maximum permitted livestock head months, season of use, and suitable acres for NFS lands under the current management alternative. No livestock grazing is authorized for the Piru and Pothole Allotments, therefore no permitted livestock numbers or season of use are listed.

1. Allotment acres calculated in ArcGIS using 2002 Term Range Permit maps. 2. Suitable acres are areas of primary and secondary rangeland forage that is available for livestock to graze. 3. Head Months (HM) refers to the number of head (cow/calf, bull, yearling, or combination) times months in season of use.
Reasoner Unit - The permittee has been authorized to graze 14 cow/calf pairs from March 1 to
February 28 for 168 head months on range 66% NFS lands in the Reasoner Unit (Table 2.1.-1).
The percentage of suitable acres on NFS land and range monitoring history determines the
permitted livestock grazing use (NFS Head Months Permitted) on NFS lands. Depending upon
the time of year, forage production, and range condition, livestock would be rotated within the
grazing areas of the Reasoner Unit, and between private and NFS lands.
Rodeo Unit - The permittee has been authorized to graze 4 cow/calf pairs from March 1 to
February 28 for 48 head months on range 69% NFS land in the Rodeo Unit (Table 2.1.-1). The
percentage of suitable acres on NFS land and range monitoring history determines the permitted
livestock grazing use (NFS Head Months Permitted) on NFS lands. Depending upon the time of
year, forage production, and range condition, livestock would be rotated within the grazing areas
of the Reasoner Unit, and between private and NFS lands.
Range Improvements
The permittees are responsible for the maintenance of structural range improvements in
accordance with Forest Service standards as per terms and conditions in part 2 of the term
Lower Piru Rangelands Environmental Assessment

grazing permits. Routine maintenance of range improvements (e.g., trough maintenance,
cleaning, repair or replacement in kind; fence mending; spring box repair or cleaning; water pipe
repair or replacement; or other similar maintenance of improvements) is completed by the
permittees as authorized by the forest officer in charge. The range improvements listed in
Appendix B and displayed in Figure 1.2-1 were authorized for the Piru, Pothole, and Temescal Allotments under the original 2002 Term Grazing Permits. The current management alternative
column displays those range improvements that are authorized under the current permits, and
would be permitted under this alternative. Fence lines are not listed in Appendix B and are
displayed in Figure 2.1-1.
Private land improvements within the project area have been included to show how livestock are
managed in the allotments, and how livestock move between private and NFS lands within the
allotments. Private land range improvements are typically not monitored or inspected by the
Forest Service. Road and trail improvements are listed in tables 2.1-7 and 2.1-8.
Roads
Two types of roads are on NFS lands within or adjacent to the Temescal Allotment: National
Forest System Roads (NFSR) and authorized non-system roads. NFSRs serve multiple uses, and
are managed and maintained as part of the National Forest Transportation System. Three NFSRs
provide access to the project area, 4N13 (Piru Canyon Road), 4N14 (Dominguez Canyon Road),
and 4N14A (Lime Canyon Road). The Forest Service maintains these roads in accordance with
road management objectives and Forest Service standards and guidelines.

Authorized non-system roads are another type of road on NFS lands within the project area.
These are listed in Table 2.1-3. Closed to public entry, these roads are used almost exclusively
for vehicle access and livestock ingress and egress for allotment management and maintenance.
Other authorized activities include private land access, Forest Service administrative access, and
wildfire suppression operations. Authorized non-system roads are authorized by a special use
permit. Private land roads within the Temescal Allotment are included only to show how
livestock are managed between private and NFS lands within the allotment. Some private roads
are not authorized for permittee use from other private landowners. Maintenance of authorized
non-system roads is completed by the permittee in accordance with Forest Service standards with
Lower Piru Rangelands Environmental Assessment

oversight provided by the Forest Service. Maintenance is completed to retain or restore access
for high clearance four-wheel drive vehicles. In some instances, maintenance includes use of
heavy equipment (e.g., grader, bulldozer, or backhoe) to repair the road surface, drainage
features, and road corridor. Where a road intersects a stream channel, periodic maintenance is
required, particularly after winter flood events.

project area, but NFST 18W04 travels through the Pothole Allotment. Other non-system non-
motorized trails are authorized to provide foot and livestock access within the project area.
Private land trails are included only to show how livestock are managed between private and
NFS lands within the project area. The authorized non-system trails may receive maintenance to
retain the route for continued livestock management use. Hand tools and motorized power tools
may be used to complete maintenance to the trail tread, drainage features, and prevent vegetation
encroachment within the trail corridor.

Resource Protection Measures and Strategies
In the planning and implementation of management activities, the Forest Service uses many
resource protection measures and strategies to reduce or prevent negative impacts to natural
resources and the environment and to meet or move towards desired conditions. The current
management alternative will implement the following resource protection measures on the
Temescal Allotment and will be incorporated into new term grazing permits. The applicable
Forest Plan standards, guidelines, and strategies are included in Appendix A.
a. Utilize Best Management Practices (USDA-FS 2000) described in Appendix C. b. Apply the Five-Step Project Screening Process for Riparian Conservation Areas (S47)
described in Forest Plan Appendix E (USDA-FS 2005c, pg. 11). Application of this process
to this project is shown in Appendix D.
c. Manage water developments to sustain both the needs of spring site surroundings as well as off-site water. Management practices may include: 1) controlling availability of developed
water to livestock, 2) hauling water to temporary tanks to influence livestock distribution and
obtain use in areas that normally receive light to no use (location of tanks may be moved
around the allotment), 3) constructing new water developments to mitigate resource concerns
(option 3 would require a supplemental NEPA document and decision). Fencing the spring
source and habitat may also be necessary depending on the distance to the off-site water.
d. Reconstruct and/or replace existing range improvements in the same footprint when their useful life expectancy is reached, or to respond to natural events (e.g., fire or floods).
e. Ground disturbing activities such as installation of water developments, pipelines, fences or enclosures may require additional environmental analysis if not covered in this document.
Cultural resource and biological species surveys may be required prior to maintenance and
implementation of range improvements.
f. Application of pesticides (or other chemicals) is not authorized under this proposal. g. The permittee will be required to monitor noxious and invasive weeds and report any new
infestations to the Forest Service. The permittee will be required to make efforts to prevent
introduction of new noxious and invasive weeds, and to prevent or minimize the spread of
existing noxious and invasive weeds (USDA-FS 2005c, pp. 121-130) as deemed necessary.
If funding is available, focused treatments will be conducted on priority areas or new
infestations of invasive weeds.
h. To avoid adverse effects to California condor the Forest Service will communicate throughout the year with the US Fish and Wildlife Service (FWS) California Condor
Recovery Program to obtain nest site, foraging, and roosting activity within the project area.
The objective is to “Avoid or minimize disturbance to breeding and roosting California
condors by prohibiting or restricting management activities and human uses within 1.5 miles
of active California condor nest sites and within 0.5 miles of active roosts” (Standard 28)
(USDA-FS 2005c, pg. 8).
i. Motorized cross-country travel may be authorized only where existing roads do not provide adequate access to conduct allotment management and maintenance of improvements.
Motorized cross-country travel will be limited and by exception only. It will require prior
review and authorization from the Forest Service officer in charge before implementation.
The review will evaluate the need for the use, ensure the minimum tool is used, and ensure
resources are protected. In the Sespe-Frazier IRA (SFIRA), ATVs should be strongly
Lower Piru Rangelands Environmental Assessment
19 | P a g e
considered over high clearance vehicles. Only temporary authorizations will be given to
specific requests and will specify when and where travel may occur. Recurring use of an
access way will be avoided to ensure a route is not established on the landscape. Additional
considerations include time of year to mitigate soil impacts and fire hazards. Cross-country
travel will be included in regular monitoring.
j. To protect the SFIRA and wilderness characteristics, maintenance of authorized non-system roads in the SFIRA or wilderness will not exceed historic levels, and will not result in the
improvement or an increase in the use of the roads.
Monitoring
Monitoring of the allotment consists of two methods: annual implementation (short-term)
monitoring and effectiveness (long-term) monitoring. Implementation monitoring is completed
annually or as needed, and evaluates whether livestock management is being applied as
prescribed. The Forest Service, with the assistance and cooperation from the permit holders,
conducts this type of monitoring through inspections of the allotments to evaluate whether
livestock management is in compliance with the terms and conditions of the term grazing
permits.
Effectiveness monitoring determines whether the project area is meeting or moving toward
desired conditions, and if the rate of change is acceptable (within the scope of this analysis). The
rate of acceptable change is determined by the Forest Service officer in charge unless otherwise
directed. If the monitoring shows that Forest Plan or project-specific desired conditions are not
being met, the Forest Service officer in charge reviews the situation to determine an appropriate
change in management to improve conditions. Monitoring of allotment and resource conditions
is completed in accordance with Forest Service requirements and in compliance with the Forest
Plan.
Table 2.1-5 describes the implementation and effectiveness monitoring strategy for the Temescal
Allotment. Key Area sites are those established rangeland monitoring locations. They are
defined as “a portion of the range, which, because of its location, grazing or browsing value,
and/or use serves as an indicative sample of range conditions, trend, or degree of use seasonally”
(USDA-FS 2005a, pp. 42-43). Other sites are monitored to determine what impact, if any,
grazing activities are having on biological and archaeological resources. Monitoring sites are
established in woodlands along grazed streams to ensure Forest standards are being met.
Woodlands along grazed streams are habitats along ephemeral or perennial stream corridors
where riparian vegetation may or may not exist. Some ephemeral stream corridors contain oak
woodland or chaparral vegetation, but no riparian vegetation.
Biological resource monitoring occurs regularly based on livestock management activities in
known threatened, endangered, and sensitive (TES) species habitats and breeding locations.
Regular coordination with the FWS California Condor Recovery Program occurs throughout the
year to determine breeding status and movements in the Ojai Ranger District surroundings.
Southwestern willow flycatcher (SWFL) breeding habitat assessments and bird surveys will
occur, if fencing is not maintained or installed to restrict livestock from potentially suitable
SWFL habitat in Reasoner Canyon. Additional biological surveys and monitoring of TES
Lower Piru Rangelands Environmental Assessment
20 | P a g e
species will occur as livestock management activities change, and with changes in status of
species.
Monitoring of known cultural resources within the allotments is necessary to ensure long-term
resource protection. Identified cultural resources are monitored periodically to establish
prescribed treatment measures and their effectiveness. If treatment measures are found not to be
effective or adverse impacts to cultural resources by rangeland use is noted, corrective measure
will be taken.

Alternative 2 – Proposed Action
Alternative 2, also referred to as the proposed action, is the result of extensive analysis and
consultation with interested individuals and groups over the last nine years. In summary, the
proposed action would allow livestock grazing to continue in the Temescal Allotment (Reasoner
and Rodeo Flat Units) similar to what has occurred in the recent past, and authorize livestock
grazing on the Piru and Pothole Allotments with appropriate mitigations and improvements as
necessary to protect resources.
The proposed action has been developed to meet the purpose and need for action as described in
Chapter 1 (Table 2.1-6), and has also been designed to respond to issues identified through
scoping activities. Alternative 2 is expected to result in protection of threatened, endangered,
and sensitive species and their habitats, including the arroyo toad and southwestern willow
flycatcher. Additionally, the proposed action has been designed to protect riparian conditions
and rangeland condition for long-term sustainability and future livestock grazing. This
alternative also includes revised boundaries for Piru, Pothole, and Temescal Allotments that
more accurately reflect natural barriers (Figure 2.1-2).
Lower Piru Rangelands Environmental Assessment
23 | P a g e
Figure 2.1-2. Alternative 2 – Proposed Action Map.
Lower Piru Rangelands Environmental Assessment
24 | P a g e
This alternative is based on the principle of adaptive management, a process that uses focused
monitoring information to determine if management is meeting or making satisfactory movement
toward desired conditions, or if changes are needed to meet or move existing resource conditions
toward desired conditions. Adaptive management is a process that allows the Forest Service to
manage for changing conditions and new information over time. It gives the Forest Service
officer in charge the flexibility to adapt to change within the constraints imposed by the EA and
subsequent decision. As long as implementation continues to remain within the scope of the EA,
the Forest Service may choose to implement adaptive changes. Examples of adaptive changes
include adjusting dates for grazing, livestock numbers, class of animal, grazing system, and those
described in Table 2.1-6. If a needed change has not been evaluated within this EA, additional
NEPA analysis and decisions may be necessary.
Alternative 2 incorporates the improvements listed in Alternative 1 unless otherwise described.
The proposed action includes updates to livestock grazing use, proposed and eliminated
improvements, resource protection measures and strategies, adaptive management, and
monitoring. The livestock management elements differ from current management practices and
improvements described in Alternative 1.
The proposed action has been designed to address the needs identified in Section 1.3. Table 2.1-
6 describes the proposed actions and improvements that would meet the identified needs. For the
proposed actions and improvements, if monitoring determines they are not having the intended
effect, then the adaptive management options may be implemented.

Livestock Grazing
This alternative proposes livestock use numbers greater than the current management alternative.
The increases are attributed to the addition of the Piru and Pothole Allotments to this alternative,
where livestock use and allotment management were excluded in previous term grazing permits.
In addition, the 2000 range analysis report and field analysis calculated an increase in total
suitable rangeland acres compared to past calculations. The season of use reflects the current
management alternative and past practice. The NFS head months result from monitoring of
livestock use on suitable rangelands and the capability of those rangelands to produce forage.

This alternative proposes changes to the allotment boundaries and updates the suitable rangeland
acreage calculations using available geographic information systems (GIS) data. The Piru
Allotment would no longer include areas in the eastern allotment (SBBM, T 5N, R 17W,
Sections 6, 7, and 18). The western boundary would be adjusted to remove part of the Piru
Creek and Canton Canyon Creek riparian corridor, as well as extend sections of the western
boundary to Canton Canyon ridgelines. The eastern boundary of the Piru Allotment would be
adjusted to reflect the existing natural barriers. For the Piru Allotment, the net acreage change
would reduce by 100 acres. For the Pothole Allotment, all private lands are removed from the
eastern and southern portion of the allotment. Other changes would include a management unit
boundary between the Lisk and Pothole Units, and moving the allotment boundary to nearby
ridgelines that would serve as natural barriers to livestock movement. All of these changes
would result in a net reduction of 598 acres in the Pothole Allotment. The Temescal Allotment
would remain nearly the same with the acreage reduced by 26 acres. The allotment boundary
line would be moved to nearby ridgelines and private land boundaries. Adjustments would be
made to the management unit boundary between Reasoner and Rodeo Flat Units. (Figure 3.6-1)
Details regarding suitable acres, number of livestock, and the season of use are described in
Table 2.1-7. The numbers of animals allowed may change based on adaptive management
options and strategies (Table 2.1-6 and Proposed Action, Resource Protection Measures and
Strategies). Suitable acres are those areas of primary and secondary rangeland forage that is
available for livestock to graze. Head months refers to the number of head (cow/calf, bull,
yearling, or combination) times the months in season of use. The numbers of livestock and
season of use may vary annually depending upon forage and water availability. However, the
proposed action sets the maximum annual authorized use in head months.

Range Improvements
Livestock improvements are necessary to manage cattle within the allotments. They include
cattleguards, corrals, fences, free fences, gates, springs, water developments, roads, and trails.
Free fences are shorter lengths of drift fences that direct or contain livestock to preferred areas or
prevent livestock from using certain areas. Standard fences can include drift fences, but serve
primarily to delineate allotment, unit, or private land boundaries. Existing improvements occur
within the allotments, both on NFS lands and adjacent private lands (Appendix B), and will
continue to be used under the proposed action alternative. The removal of private land from the
Pothole Allotment boundary eliminates those range improvements (Table 2.1-8) under this
alternative. Existing fence lines are included in (Figure 1.2-1). Installation of new fences and
gates is required in all of the allotments to protect resources and manage livestock. Proposed
improvements on NFS lands are detailed in Table 2.1-9.

non-system roads under past grazing permits would be permitted within the Piru and Pothole
Allotments. The authorized non-system roads have been used historically for the management
and maintenance of the grazing allotments and will continue to be used under the proposed
action. One section of road in the Temescal Allotment will be eliminated. The upper segment of
the Reasoner Canyon Road will be converted from a road to a motorized trail (Table 2.1-12). No

grader, dozer, or backhoe) to repair the road surface, drainage features, and road corridor. Where
a road intersects a stream channel, periodic maintenance would be required, particularly after
winter flood events. The maintenance needs recorded in Table 2.1-11 describe those specific
actions which are needed to restore the roads to its previous condition and to provide continued
use and access. In inventoried roadless areas maintenance will be limited to those actions needed
to retain and restore access, and will not constitute construction or reconstruction in accordance
with Forest Service regulations.

Some of the roads that were used under previous grazing authorizations will no longer be needed
as roads for continued grazing allotment management (Table 2.1-12). A 0.7 mile segment of the
Reasoner Canyon Road will be converted to a motorized trail. In the Temescal Allotment a total
of 0.1 miles of authorized non-system roads on NFS lands would be eliminated from future use
and maintenance activities under new term grazing permits. The eliminated road exists in a
hydrological maintenance free condition. Resource impacts are not present, therefore no
treatments or maintenance are necessary. Private land roads are included only to show
connectivity of livestock management between private and NFS lands within the allotments
(Figure 2-1.2).

Trails
Under this alternative, the majority of previously authorized non-system trails across the project
area would be eliminated from future livestock access and allotment management (Table 2.1-13).
The eliminated trails exist in a hydrological maintenance free condition and require no
rehabilitation to mitigate resource impacts. Many of the trails have already reverted to natural
conditions. An authorized non-system trail in the Lisk Unit of the Pothole Allotment that was
previously authorized under a past term grazing permit would be maintained. In Reasoner
Canyon on the Temescal Allotment, a 0.7 mile section of authorized non-system road would be
converted to an authorized non-system motorized trail. Within the Pothole Allotment, the
Pothole Trail (NFST 18W04) would be utilized for range management. However, nearly one-
half mile of the Pothole Trail, and use of four miles of the Agua Blanca Trail (NFST 19W10)
outside the project area and previously authorized in past grazing permits, would no longer be
authorized for livestock management (Table 2.1-14). Private land trails are included only to
show connectivity of livestock management between private and NFS lands within the
allotments.

Existing trails described under this alternative have been used under previous grazing permits.
These trails include the Pothole Trail (NFST 18W04), Reasoner Canyon Trail (authorized non-
system motorized), and Reichenbach Trail (authorized non-system). NFSTs are maintained by
the Forest Service in accordance with trail management objectives and Forest Service standards
and guidelines. The authorized non-system trails receive maintenance to retain the route for
continued livestock management use. When appropriate, hand and motorized power tools would
be used to complete maintenance to the trail tread, drainage features, and prevent vegetation
encroachment within the trail corridor.
The Reasoner Canyon Trail would provide access for ATVs and would be maintained up to 50
inches in width. Heavy equipment appropriate for maintaining the motorized trail may be used
when needed to repair and retain the trail for ATV access along the trail tread and corridor. This
trail would be the only motorized trail within the project area.
Resource Protection Measures and Strategies
In the planning and implementation of management activities, the Forest Service uses many
resource protection measures and strategies to reduce or prevent negative impacts to natural
resources and the environment, and meet or move towards desired conditions. Additional site
specific resource protection measures and strategies were developed by the interdisciplinary
team to respond to identified issues and management needs. The proposed action would
implement the following resource protection measures and strategies for the Piru, Pothole, and
Temescal Allotments and will be incorporated into the new term grazing permits. The applicable
Forest Plan standards, guidelines, and strategies are included in Appendix A.
a. Utilize Best Management Practices (USDA 2000) described in Appendix C. b. Apply the Five-Step Project Screening Process for Riparian Conservation Areas (S47)
described in Forest Plan Appendix E (USDA-FS 2005c, pg. 11). Application of this process
to this project is shown in Appendix D.
c. Water developments would be managed to sustain both the needs of spring site surroundings as well as off-site water. Management practices may include: 1) controlling availability of
developed water to livestock, 2) hauling water to temporary tanks to influence livestock
distribution and obtain use in areas that normally receive light to no use (location of tanks
may be moved around the allotment), 3) constructing new water developments to mitigate
resource concerns (option 3 would require a supplemental NEPA document and decision).

Fencing the spring source and habitat may also be necessary depending on the distance to the
off-site water.
d. Reconstruct and/or replace existing range improvements in the same footprint when their useful life expectancy is reached or to respond to natural events (e.g., fire or floods).
e. Prior to receiving an authorization for grazing the permittee must construct, re-construct or maintain fencing in the Piru and Pothole Allotments to restrict cattle from entering United
Water Conservation District lands, Lake Piru Recreation Area, Piru Reservoir, and Piru
Creek.
f. A fence installation strategy will be utilized to ensure fencing management needs are protecting resources and meeting or moving towards desired conditions:
Utilize and maintain existing fencing.
Other range management options may be utilized prior to installation of proposed fencing.
Construct proposed fence sections at the most likely points of access to restrict livestock movements.
Install additional fence (temporary electric free fence, permanent free fence, or permanent continuous fence) as needed until unplanned livestock access is avoided.
The permittee is responsible for acquiring the range materials, and for constructing and
maintaining fences and other range improvements. When funding is available, the Forest
Service would provide range improvement materials.
g. Ground disturbing activities such as installation of water developments, pipelines, fences or enclosures may require additional environmental analysis if not covered in this document.
Cultural resource and biological specie surveys may be required prior to maintenance and
implementation of range improvements.
h. Application of pesticides (or other chemicals) is not authorized under this proposal. i. The permittee will be requ
