Detailed habitat assessments were conducted by CBI, TNC, and SDSU within the four designated South County grassland management planning units: Sweetwater Reservoir, Proctor Valley, Rancho Jamul Ecological Reserve, and Sycamore Canyon (Figure 1). All four units were assessed in 2011; additional assessments were conducted in 2012 at Rancho Jamul Ecological Reserve and Sycamore Canyon. The purpose of these assessments was to document existing habitat conditions and determine habitat suitability for the three target species (burrowing owl, Otay tarplant, and Quino checkerspot butterfly), as well as threats, results of past management actions, and potential management and restoration actions. Data from the habitat assessments were used to identify and prioritize species-specific management actions within each of the four planning areas. In addition, these data were used to identify preliminary vegetation associations, as well as potential restoration sites for native grasslands and forblands. Prior to conducting fieldwork, CBI and TNC reviewed soil maps, aerial photographs, and results of previous vegetation mapping, and plant and wildlife surveys in the project areas and vicinity.

Quino checkerspot butterfly (Euphydryas editha quino) was listed as an endangered species on January 16, 1997 (63 Federal Register 2313–2322). Since that time, a captive propagation program has been established to guard against extinction of the species in the wild and to provide stock for release within the species former range. Although this program has successfully produced new generations of butterflies, the program as a whole lacks a longterm plan and decision making framework to evaluate which individuals should be released at which locations to maximize the probably of survival of the species at release sites. Genetic diversity is a serious concern for populations of butterflies kept in captivity (Crone et al. 2007; Snyder et al. 1996) and therefore operating procedures and record keeping are necessary to minimize selection and drift in captivity. This document assesses the current status of the captive rearing program and provides a framework to guide future actions involving reintroduction, augmentation and captive propagation of this taxon. Any captive propagation protocol and release plan for Quino checkerspot butterfly must ensure that the captive propagation program is consistent with the USFWS Policy Regarding Controlled Propagation of Species Listed Under the ESA (65 Federal Register 56916). This plan addresses the 14 criteria in the captive propagation policy and includes:identification of measurable objectives and milestones for the program, a clear endpoint for the program, general operating procedures for rearing and release, guidance for data collection and management, a decision making structure to guide reintroduction strategies, and a post-release monitoring strategy.
FLITE Tours, Ino, BDA: Klein-Edwards Professional Services (KEPS) was retained by the U'S'
Fish and Wildlife Service to conduct post-firc monitoring for the fferally endangered Quino
checkerspot butterfty (Euptrydryas editho quino) on the Otay Truck Trail site located in the
County oisan niego, California KEPS's survey_s were conducted according to the U.S' Fish
and Wildlife Servile protocols for this species (USFWS 2002). A total oft€n (10) 9ry _
checkerspot butterflies were detected on site. The sigbtings were are follows: 5 adults (3 females
and 2 males) on a mesa just east of Wild BilI Canyon and 5 adul* (1 feurale and 4 males) ju*
outside of BLM jurisdictional lands within lands owned urd managed fomrerly by the
Environmental Trust. This rcport provides the results and conclusions of KEPS's 2005 surveys
for the adult Quino checkerspot butterfly.
Chambers Group, Inc. was retained by the Bureau of Land Managemenl (BLM), to conduct a habitat assessment and focused adult surveys to delermine the presence/absence of the Quino checkerspot butterfly (Euphydryas editha quino), within three sections of ihe Intemational Fuel Break (fuel break). The total survey area encompesses approximately 438 acres in San Diego County, Califomia. Surveys are broken into three sites: Shockey, Truck trail, Tecate Peak, Otay Mountain fuel break.
Of the three survey areas along the lntemational Fuel Break during the 2002 flight season, Quino checkerspot butterfly was only observed on the Otay Mountain portion of the fuel break. Although Shockey Truck Trail and Tecate Peak had suitable topographical features (hilltops and ridgelines, etc.), host plants, and nectar sources, the results of the focused surveys were negative at these two locations. Overall butterfly activity was moderate, with over 25 species of butterfly observed during the course of the 2002 surveys. The most detrimental activities to Quino include an increase in frequency of hand clearing and prescribed burns in areas along the fuel breaks that contain suitable topography and abundanl host plants and nectar sources.
Surveys for the quino checkerspot butterfly (QCB) were conducted by Ms. Holly Boessow under PRT-837307 and Mr. Keith Greer under TE-842199-2 during the 1999 QCB flight season (March 1 through May 10, 1999).

The sighting was as follows: 1 adult male just outside of BLM jurisdictional lands within lands owned and managed formerly by the Environmental Trust. This report provides the results and conclusions of KEPS's 2006 surveys for the adult Quino checkerspot butterfly.
This report provides the proposed adaptive management and monitoring strategy to be implemented as part of the County of San Diego?s Quino Checkerspot Butterfly Amendment (Quino Amendment) to the Multiple Species Conservation Program (MSCP) Subarea Plan (County Subarea Plan). By providing a concise summary of the proposed adaptive management and monitoring strategy, this report will facilitate review by staff, analysts, consultants, property owners, and the Wildlife Agencies (California Department of Fish and Game and U. S. Fish and Wildlife Service). It is assumed that reviewers of this report have prior knowledge of the County Subarea Plan and Quino Amendment. Other aspects of the Quino Amendment (i.e., conservation policies and financing) are addressed in separate review processes. Additionally, information in this report is additive to management actions in the Framework Management Plan (County of San Diego 2001).
Below, aspects of Quino checkerspot butterfly (Quino) habitat requirements, metapopulation dynamics, and existing threats relevant to the design and implementation of the adaptive management and monitoring program are summarized. Next, specific adaptive management and monitoring goals are described, along with proposed strategies for reaching those goals. Adaptive management and monitoring will be focused in preserves within the South County, Alpine-Jamul, and San Vicente Quino Management Units (QMU) (Figure 1). The adaptive management and monitoring program is intended to be flexible enough to allow for adjustments as new information is available and more is learned regarding appropriate strategies for maintaining Quino populations.
Surveys for the quino checkerspot butterfly (QCB) were conducted by Ms. Holly Cheong under PRT-837307 and Mr. Keith Greer under TE-842199-2 during the 2003 QCB flight season.
The +84-acre Marron Valley Road property was carefully surveyed during the FWS-monitored survey period to determine if the endangered Quino checkerspot butterfly (Euphydryas editha quino; QCB) was present onsite. No QCB's were found during these surveys. The recent fire through the area does not provide the best conditions for the butterfly. Those areas that were not affected by fire were carefully searched as well as areas that were burned but recovering.

FLITE Touts,Inc, BDA: Klein-Edwards Professional Services (KEPS) was retained by the U. S. Fish and Wildlife Service to conduct post-fire monitoring for the federally endangered Quino checkerspot butterfly (Euphydryas editha quino) on the Otay Truck Trail site located in the County of San Diego, California. KEPS's surveys were conducted according to the U. S. Fish and Wildlife Service protocols for this species (USFWS 2002). A total of four (4) Quino checkerspot butterflies were detected on site. The sightings were as follows; 4 adults (2 males) on a hill east of the entrance to the DFG preserve which is also east of the glider port, 1 adult (1 male) hilltopping on a hill above an un-named canyon southeast of-the glider port and 1 adult (1 male) on a series of hills due south of the central portion of thecentral portionof the glider port. This report provides the results and conclusions of KEPS's 2005 surveys for the adult Quino checkerspot butterfly.
This report provides the project processing procedures proposed as part of the County of San Diego?s Quino Checkerspot Butterfly Amendment (Quino Amendment) to the Multiple Species Conservation Program (MSCP) Subarea Plan (County Subarea Plan) and an analysis of anticipated conservation levels. By providing a concise summary of these critical issues, this report will facilitate review by staff, analysts, consultants, property owners, and the Wildlife Agencies (California Department of Fish and Game and U. S. Fish and Wildlife Service). It is assumed that those reviewing this report have prior knowledge of the County of San Diego?s Multiple Species Conservation Program (MSCP) South County Subarea Plan (County Subarea Plan) and Quino Amendment.
In general, the Quino Amendment will provide assurances for the long-term conservation of Quino within the County Subarea while allowing for public and private development consistent with the approved Implementing Agreement for the County Subarea Plan. Upon approval of the Quino Amendment, Quino will be included as a Covered Species Subject to Incidental Take under the County Subarea Plan. Such authorization is necessary because otherwise lawful activities associated with construction of public and private projects in the County Subarea will result in the modification and destruction of Quino habitat.
Surveys were conducted to determine the presence or absence of QCBs on lands owned by the City of San Diego. 45-day reports were submitted to the Carlsbad Field Office on June 24, 2003. The objective of these surveys was to enhance the survival of the QCB by locating populations of the species and reporting those findings to the U. S. Fish and Wildlife Service (USFWS).

Jones & Stokes conducted a baseline biodiversity study of the County of San Diego?s Boulder Oaks Open Space Preserve (Preserve) to provide the Department of Parks and Recreation with the biological data to develop Area Specific Management Directives (ASMDs). The Preserve consists of very high value natural communities and is located approximately three miles south of the unincorporated township of Ramona, between State Route 67 and Mussey Grade
Road, in central San Diego County, California.
During 2007, Jones & Stokes? biologists conducted the following studies, in addition to general, qualitative evaluation of the entire Preserve: (1) mapping of
vegetation communities, (2) a floral inventory including rare plant surveys, (3) a focused survey for Quino Checkerspot butterfly, (4) a habitat evaluation to
address Arroyo Toad, (5) pitfall trap arrays to sample amphibians, reptiles, and small mammals, (6) avian point counts, (7) a nocturnal bird survey, (8) acoustic
sampling and roost surveys for bats, (9) a track and sign survey for medium-tolarge mammals, and (10) a camera station survey for medium-to-large mammals.
Due to the low rainfall during the 2006-2007 winter, results of these surveys may under represent the diversity of plants and wildlife that occur within the Preserve.
Rancho Jamul Ecological Reserve, a 3,700-acre property previously operated as a
cattle ranch, became part of the California Department of Fish and Game reserve system in
1998. Following this acquisition, the U.S. Geological Survey conducted surveys to establish
baseline species data and vegetation data layers. Through cooperation with San Diego State
University, a vegetation and land cover GIS layer was developed which details the extent and
types of vegetation classes found on the reserve. This vegetation mapping established that 15
native and non-native vegetation types, the majority of which had disturbed counterparts,
occurred throughout the reserve. Rare plant surveys conducted by McMillan Biological
Consulting provided documentation of 131 native and non-native plant species, 18 of which
are considered sensitive species. Of these, five plant species detected on the reserve are
covered under the Multiple Species Conservation Program. Aquatic surveys reported four
native and two non-native amphibian species and six non-native fish species. Herpetofauna
pitfall arrays detected four native amphibian species, ten lizard species, and twelve snake
species. Twenty-one ant species were recorded using ant pitfall traps co-located at the
herpetofauna pitfall arrays. Bird point counts and incidental bird sightings recorded 94 bird
species present on or near the study site. Twelve bat species were detected using mist
netting, acoustic surveys, and roost site visits. Sherman live traps, combined with
herpetofauna pitfall arrays small mammals captures, documented 14 small mammal species
present on the reserve. Remotely triggered cameras and track stations were used to
document the presence of 11 medium and large bodied mammal species. A total of 150
native vertebrate species and nine non-native vertebrate species were recorded during these
surveys. Two herpetofauna species, eight bird species, and two mammal species detected on
the reserve are covered under the Multiple Species Conservation Program. Incidental records
of the Quino checkerspot butterfly were made onsite during the rare plant surveys, adding
this reserve to its known distribution. Summary statistics, discussion, and management
recommendations on the flora and fauna of the Rancho Jamul Ecological Reserve are
provided in this report.
The Otay Ranch Preserve (Preserve) consists of approximately 525 acres in the San Ysidro
Mountains and approximately 826 acres in Salt Creek in the City of Chula Vista (City) in San
Diego County. Dudek biologists have performed the following surveys: vegetation mapping in
May and June 2008, focused botanical surveys in spring 2009, general butterfly surveys in 2008,
focused surveys for quino checkerspot butterfly (Euphydryas editha quino) in spring 2009,
focused surveys for coastal California gnatcatcher (Polioptila californica californica) in
spring 2008, avian point count surveys in summer/fall 2008, and large and medium mammal
surveys in spring 2009. Herpetology trap surveys are currently in process. This report documents
the results of Dudek's field work.
This report summarizes the results of the site assessment performed by EDAW, Inc., including a review of historical data, and identifies the most appropriate techniques for restoring and managing vernal pool habitat to increase sensitive species presence and hydrological function and value. The report includes five key chapters, as follows: Chapter 1.0 provides an introduction to the project and the project background; Chapter 2.0 details the vernal pool site assessment approach and summarizes the assessment results; Chapter 3.0 describes the approach to site restoration and management; Chapter 4.0 provides comprehensive restoration management recommendations for each site; and Chapter 5.0 provides the priority site recommendations based on existing grant funds, including an estimated schedule and cost for implementation.
Vernal pool habitat in southern California, and specifically southern San Diego County, has been
greatly diminished as a result of extensive development throughout the region. The value and
function of remaining vernal pool habitat continue to be degraded by development-related
disturbances such as trespassing, grazing, and invasion of nonnative species. As a result, the
sensitive species that are supported by vernal pool habitat are also at risk. To halt the
decline and stabilize the vernal pools in San Diego County, and restore habitat function and
sensitive species populations, restoration and management actions are necessary.
The City of San Diego (City), in cooperation with other coordinating agencies such as the
County of San Diego (County), San Diego Association of Governments (SANDAG), U.S. Fish
and Wildlife Service (USFWS), California Department of Fish and Game (CDFG), and
California Energy Commission (CEC), obtained grant funding
to protect, restore, and manage
portions of the remaining vernal pool habitat in southern San Diego County. AECOM (formerly
EDAW, Inc.) was retained by the City to conduct a comprehensive assessment of existing vernal
pool sites within the jurisdiction of the City and County, develop and prioritize recommendations
for restoration and management of those sites, and implement restoration and management of the
sites.
This report summarizes the results of implementation of the restoration and management
recommendation actions at five key vernal pool sites in the County.
BCLT and AECOM used the EMP funds for restoration of
native grassland habitat at BCLT’s property, Wright’s Field, located in Alpine, California (the Project).
Specifically, funds were utilized to restore and enhance the two remaining San Diego thornmint
(Acanthomintha ilicifolia; thornmint) populations, as well as Quino checkerspot butterfly (Euphydryas
editha quino; Quino) host plant (Plantago erecta; plantago) populations. Wright’s Field populations of
both species are facing extirpation due to nonnative plant invasion. Working in partnership with
AECOM’s highly skilled and qualified restoration team, BCLT implemented restoration and enhancement
on two sites within native grassland habitat, both of which support thornmint and plantago. Restoration
and management activities included removal of nonnatives; seed collection, bulking, and redispersal;
monitoring (qualitative and quantitative) and reporting; resource agency coordination; volunteer
training; and public outreach and education.
