I went to the woods
because I wished to live deliberately, to confront only the essential facts of
life, and see if I could not learn what it had to teach, and not, when I
came to die, discover that I had not lived.

Yucca whipplei
Cover Illustration: Yucca whipplei
by Lisa Pompelli
Yucca whipplei
occurs widely in coastal sage scrub and chaparral habitats from Monterey
County south into northwestern Baja California. The common name of our
lord’s candle comes from the presence in spring of a tall flowering stalk
4-8 feet in height covered with cream-colored flowers. This species has a
remarkable mutualism with an insect called the yucca moth. All pollination
of yucca flowers is carried out by this moth, which then lays its eggs in
the young seedpods. The developing moth larvae feed on some but not all of
the seeds in each of the pods. Neither species can survive without the
contributions of the other.

Narrative
Overview 2001-2002
Academic
years, as do most yearly cycles, seem to have their own focus. In the life
of the Stunt Ranch Reserve, besides instruction and research, the
2001-2002 year focused on mediterranean-climate regions, the Los Angeles
Times reading by 9 literacy program, reconstruction planning, and outreach
to the public about the importance of preserving and enhancing
biodiversity.
An international symposium on Managing Conservation lands in
Mediterranean-Climate Ecosystems was held April 2-4 at UCLA to discuss
issues and challenges of managing parklands at the urban/wildland
interface adjacent to the large metropolitan areas of Los Angeles and Cape
Town. This workshop brought together a large group of resource managers
and conservation biologists from Southern California and South Africa to
learn from their respective experiences and to develop new approaches
toward effective resource management. Shortly afterward, a similar program
was conducted with resource managers from Chile.
For details, see On-site community outreach activities and
Miscellaneous.
A related project was the production of a visually attractive educational
poster which identifies the five mediterranean-climate regions, their
patterns of global occurrences, and their convergent as well as unique
characteristics. It also describes the threats these regions face as areas
of irreplaceable biodiversity whose protection is of critical global
importance.
For details, see Off-site community outreach activities.
As in past years, there was much behind the scenes activity related to the
reconstruction of the Stunt Ranch education/nature center. An Initial
Environmental Impact Report (EIR) was completed and released. The Reserve
received public response with no significant problems, and is now working
out engineering details for the utilities for the site.
With enthusiastic support from numerous agencies and organizations, and
with valued assistance from the UCLA development office and offices of
government and community relations, the Reserve applied for Proposition 12
funding to help supplement the reconstruction of its education/nature
center. Although the Reserve did receive a high ranking, the available
funds were awarded to centers in more urban locales. However, no effort is
in vain, and the well documented proposal not only will serve as the basis
for others, it has provided a valuable vehicle for outreach to various
educational and environmental organizations and communities.
The Reserve was a frequent contributor to the Los Angeles Times Reading by
Nine Literacy Program. Articles published on the Los Angeles Times Kids
Page – California Classroom section, featured plants and animals found at
the reserve. Accompanying illustrations by children between the ages of
5-12 years of age were unique to these articles

ON-SITE RESERVE USE:
The Stunt Ranch
Reserve determines use on the basis of visitor days. During 2001-2002, the
reserve had 3238 users for a total of 3860 user days. These user numbers are
broken down by university-level use from UCLA, other UC campuses, the
California State University system, and others within/outside California. In
addition to university use, the Reserve hosted environmental education
programs for K-12 coordinated by the Cold Creek Docents, and varied public
outreach programs.

thrive at the Stunt Ranch Reserve – even with sky for roof and earth for
floor. This is the title for an article featuring the Reserve in the UC
Natural Reserve System (NRS) 2002 Winter Transect (quarterly newsletter).
This year, as in others, thousands of students from dozens of schools
throughout the greater Los Angeles area visited the reserve for programs run
by the Cold Creek Docents on chaparral ecology, early Chumash culture, and
geology. These programs represented a unique and highly successful
collaboration between UCLA and the docents. The reserve benefited from the
on-going excellence of the program and the commitment of the docents. The
docents received reserve help in putting curriculum guides online, help in
publicizing the programs, and by providing enrichment opportunities.

ON-SITE COMMUNITY OUTREACH ACTIVIES:
Managing Conservation
Lands in Mediterranean-Type Ecosystems: Southern California and The Cape
Region of South Africa.
The five mediterranean-climate regions of the world have been identified as
members of a small group of evolutionary hotspots, which contain
globally significant biodiversity and are highly threatened by human
activities. Southern California and the Cape Region of South Africa are
areas among these regions, which share remarkable similarities in many
aspects of their environments. An international symposium on Managing
Conservation lands in Mediterranean-Climate Ecosystems was held April
2-4 at UCLA to discuss issues and challenges of managing parklands at the
urban/wildland interface adjacent to the large metropolitan areas of Los
Angeles and Cape Town. This workshop brought together a large group of
resource managers and conservation biologists from Southern California and
South Africa to learn from their respective experiences and to develop new
approaches toward effective resource management. Among the themes discussed
were priorities for parkland acquisition, institutional challenges to
resource management, fire management, invasive species control, and
strategies for education and public outreach. The success of this workshop
has led to plans a continuing series of formal and informal linkages between
parkland managers in all five mediterranean-climate regions. The Workshop
was sponsored by UCLA (Vice-Chancellor for Research, Stunt Ranch Reserve and
the UCLA Institute of the Environment) and by the National Park Service.
Several months later, resource managers from Chile, one of the five
mediterranean-climate regions, also met with UCLA Stunt Ranch Reserve staff
and researchers and with National Park Service and State Parks to discuss
similar issues as noted above.
Department of Organismic Biology, Ecology, and Evolution annual gathering.
The Reserve once again hosted the UCLA Department of Organismic Biology,
Ecology, and Evolution’s annual family picnic with catered food, live
entertainment provided by students from the UCLA Ethnomusicology Department,
and hikes/kids games led by the Cold Creek Docents.
For details, see Use data and user’s affiliations.
OFF-SITE COMMUNITY OUTREACH ACTIVITES:
 |
The Reserve was again
represented in the UCLA in LA community outreach booth at the annual Los
Angeles Times - UCLA Festival of Books, attended by tens of thousands of
visitors. This event provided a fun and effective venue for publicizing the
K-12 environmental program at Stunt Ranch.
|
 |
The schematics for the
Stunt Ranch Education/Nature Center as well as sample artifacts continued on
display in the lobby of the UCLA Life Science Building.
|
 |
The Reserve again was a
participant in the annual UCLA Biology Department Research Symposium. The
Reserve displayed posters and printed material on research and instructional
programs.
|
 |
Reserve staff attended
the annual UC Natural Reserve System manager’s workshop held at the Kenneth
S. Norris Rancho Marino Reserve

LOS ANGELES TIMES: READING BY 9 LITERACY PROGRAM:
The reserve was a frequent contributor to the Los Angeles Times Reading by
Nine Literacy Program. The Stunt Ranch Kids Page articles have proven to be
a successful and wide-ranging venue for the Reserve’s off-site education
efforts and the promotion of the on-site K-12 environmental education
programs. These articles were considered such a valued addition to the Kids
Reading Room Page that the Los Angeles Times requested the Reserve to write
a monthly column on recreating natures living works of art.
MEDITERRANEAN-CLIMATE REGIONS POSTER:
The mediterranean-climate regions poster, which the Reserve created in the
past year is comprised of maps of the five regions along with botanical
illustrations, charts, diagrams and watercolor paintings. Topics covered
include fire ecology, convergent evolution, biodiversity, climate
influences, human history, human impact, and seasonal patterns of
temperature and rainfall.
The poster was designed and written as an educational tool for students and
the community at large who have an interest in science and biodiversity,
especially as it translates into public policy. It can easily be
incorporated into school curricula and community workshops and seminars.
Dr. Philip Rundel, UCLA Professor of Biology and faculty director of the
UCLA Stunt Ranch Reserve, wrote the text for the poster. Artwork and design
was by Lisa Pompelli, a well-respected artist and botanical illustrator.
CENTER FOR EMBEDDED NETWORKED SENSING (CENS) AT UCLA:
Phil Rundel, Director of the Stunt Ranch Santa Monica Mountains Reserve, is
a principal investigator within the Center for Embedded Networked Sensing (CENS)
at UCLA. CENS is a new NSF Science & Technology Center working to develop
technologically innovative sensing arrays with wide applications in
environmental biology and ecosystem studies. The initial efforts of CENS are
focused on the design of a habitat and organism sensing test bed at the UC
NRS James Reserve and at affiliated field sites, which will later involve
projects at Stunt Ranch. Some of the areas of development include:
1) Sensing Infrastructure
• Environmental sensors in different habitats.
• Multimedia sensors in natural habitats and artificial cavities (nest
boxes).
• Physiological sensors on trees and shrubs.
• Primary nodes for higher level data processing and communications on
towers.
• Mobile platform for high-resolution sensors and tele-robotic operation.
2) Monitoring ecosystem processes
• Imaging, ecophysiology, and environmental sensors
• Study vegetation response to climatic trends and diseases.
3) Species Monitoring
• Visual identification, tracking, and population measurement of birds and
other
vertebrates.
• Acoustical sensing of birds for identification, spatial position,
population estimation.
VIDEO:
Burrud Productions and Schlessinger Media Company, with the help of Dr. Ken
Nagy, UCLA herpetologist and Stunt Ranch instructor, produced a set of
videos for K-12 on amphibians and reptiles. These became available in the
‘01-’02 academic year. One is about amphibians for grades K-4, another on
amphibians for grades 5-8, and the third is about reptiles for grades 5-8.
Each video is about 20 minutes long, is informative, and hopefully will
interest youngsters to learn more about these ectothermic vertebrates. For
information about these educational videos, see
http://www.libraryvideo.com/company_info/about_lvc.asp
COLLECTION OF ETHEL STUNT ARTIFACTS:
The Reserve, as in past years, was the fortunate recipient of treasured
items from the life of Stunt Ranch matriarch Ethel Stunt. These will join
others as part of a featured display on the homestead period in the Stunt
Ranch Reserve education/nature center. Items received this year included: 1
fur hood, 1 pair of glasses, 1 tin cup, 1"1888" pin, 1 carved jade frog from
China, and diaries from some of her trips to Japan and Korea dated 1910-13.
In one, Ethel noted that locals were taking advantage of some of the
foreigners in various transactions "...but not Beatrice Ethel...” A measure
of her self-esteem and confidence, which seems to confirm she was a teacher.
NEWS CLIPPINGS:
In addition to research
papers published in Ecological Research, Environmental Management,
Conservation Biology, Remote Sensing of the Environment, Southern California
Environmental Report Card, Journal of Mediterranean Ecology, and
the International Journal of Wildland Fire, news and feature articles
about the Reserve or written by Reserve staff were published in the
publications listed below.

2001-2002 Research Reports
# 1. Bush poppy demography and
productivity
Rasoul Sharifi and P.W. Rundel
Department of Organismic Biology, Ecology, and Evolution
University of California, Los Angeles
Phil Rundel and Rasoul Sharifi are in the
eighth year of a study investigating post-fire patterns of demography and
productivity in Dendromecon rigida, the bush poppy, which became
established in dense stands on north-facing slopes of the Santa Monica
Mountains following wildfires in 1993.
__________________________________________________________________
#2. Post fire successional
dynamics
P.W. Rundel
Department of Organismic Biology, Ecology, and Evolution
University of California, Los Angeles
Phil Rundel is continuing a long-term
monitoring project of permanent plots established at Stunt Ranch after the
1993 wildfire.

# 3. Long term
study of gas exchange and water relations of a chaparral plant community:
Drought effect
Rasoul Sharifi
Department of Organismic Biology, Ecology, and Evolution
University of California, Los Angeles
During
2002 we focused our study on the ecophysiological responses of the study
species to the unusual drought conditions of 2001-02, one of the driest
years of the past half-century. Our study site, Stunt Ranch, in the Santa
Monica Mountains, is a mixed community of plant species with different adaptive
strategies, including shrubs with evergreen, sclerophyllous leaves, as well
as species with soft-leaved, drought-deciduous leaves. The study species
included woody evergreens (Quercus dumosa; Q. agrifolia;
Heteromeles arbutifolia; Ceanothus spinosus; Rhamnus ilicifolia
and Arctostaphylos glandulosa), woody deciduous shrubs (Fraxinus
velutina var. coriacea; Malacothamnus fasciculatus and Ribes
speciosum), and semi-woody deciduous shrubs (Salvia leucophylla;
S. spathacea; Venegasia carpesioides and Eriogonum crocatum).
To assess the effect of soil water stress on plants physiological
performance; we compared plant midday water potentials, midmorning
assimilation and leaf stomatal conductance, during late summer of 1998, a
year with normal precipitation with summer measurements in 2002. The
drought of 2002 caused a significant decrease in plant water potential
(higher water stress) compared with 1998 in all of the study species. Plant
water potentials of deep rooted species during 2002 were 7-10% lower than in
1998 and water potentials of medium and shallow rooted species were 20 – 55%
lower than in 1998. The effect of the 2002 drought on photosynthetic rates
ranged from a 35 to 45% reduction across all the study species. The
reduction in photosynthetic rates was more moderate in deep-rooted species
than in the medium and shallow rooted species. Leaf stomatal
conductance to water vapor and transpiration for all species followed a
trend similar to plant photosynthesis.

#4. Assessing
vegetation functional type and biodiversity in Southern California using
spectral reflectance.
Brian Zutta and John
Gamon
Center for Environmental Analysis & Department of
Biology and Microbiology (CEA-CREST)
California State University, Los Angeles
The first component of
our study, as part of a thesis project, involved four 100m transects in the
Stunt Ranch (Cold Creek) watershed. Title: Functional type classification of
Southern California Vegetation using spectral reflectance. The results were
presented in a poster session of the 2000 ESA meeting in Snowbird, Utah. The
study was conducted from Dec. 1999 to Sept. 2000 and involved the use of
remote sensing (spectral reflectance), at the canopy level, to distinguish
between plant functional types such as annual, evergreen, winter, and
drought deciduous vegetation. The results indicated that classification at
this level was at least 85% successful in the spring season. This analysis
also indicated that spectral reflectance could be used to distinguish
between species, which led to a second research component. Title: Linking
biodiversity and spectral reflectance in Southern California vegetation.
This portion was conducted on 2 transects in Stunt Ranch, and 6 transects in
Cold Creek, in Spring 2001. A positive correlation was found between the
optical diversity (standard deviation) of spectral information and
biodiversity. The results were presented in an oral session of the 2001 ESA
meeting in Madison, Wisconsin, and in a poster session of the 2001 Annual
Meeting of the Southern California Academy of Sciences in Los Angeles,
California, which received the Ecology and Evolution Award.

# 5. Reproductive flexibility in the paper
wasp Polistes aurifer
Aviva Liebert (Advisor, Peter Nonacs)
Department of Organismic Biology, Ecology, and Evolution
University of California, Los Angeles
There was very little
wasp activity at Stunt Ranch for the 2002 spring and summer season, most
likely because of the extremely low winter rainfall. From late March through
early April, I checked all of my nest boxes that had been popular nesting
sites in previous years, but did not find a single P. aurifer nest. I
therefore was not able to study the wasps for another intense field season,
and instead focused on analyzing data and transcribing videotapes of wasp
behavior collected from earlier field seasons.

6.The evolutionary-ecology of fear:
comparative studies of disturbance in birds.
Dan Blumstein & Rina Fernandez
Department of Organismic Biology,
Ecology, and Evolution
University of California, Los Angeles
Birds may either sensitize or habituate to
human disturbance and patterns of sensitization may explain why some
species are unable to coexist with recreational trail use. By walking
towards birds and measuring the distance at which they flee from an
approaching human, we have been studying the degree to which they
habituate or sensitize as a function of changes in pedestrian pressure. We
have found that many species of scrub birds seemingly sensitize. On-going
work seeks to determine why.

# 7. Environmental
monitoring and bioassessment of Ventura and Los Angeles County Watersheds
Richard F. Ambrose
Environmental Science and Engineering Program
University of California, Los Angeles
During Fall 2001, we
sampled a number of sites throughout the Malibu Creek watershed (as well as
Calluegas Creek and Santa Clara River watersheds) to examine the influence
of different land uses on the ecosystem health of stream communities.
Sampling locations in the Malibu Creek watershed included a number of sites
along Cold Creek, including a site in the Cold Creek Reserve that serves as
a reference site representing relatively undisturbed conditions in the Santa
Monica Mountains (also used by Heal the Bay in their watershed monitoring
program). We sampled many of the physical (water chemistry and flow,
channel morphology, substrate, light) and biological (riparian vegetation
characteristics, algae and macrophytes, benthic macroinvertebrates, fish)
features that contribute to the overall health of stream ecosystems. While
our project targeted individual sites based upon their land use
characteristics, our overall objective is to understand the factors
influencing the structure of stream benthic communities, particularly
benthic macroinvertebrates. In the past year, we have been completing
laboratory analyses of the samples and statistical analyses of the data.

#8.
Ecophysiology of ferns in chaparral and oak woodland habitats of the Santa
Monica Mountain
P.W. Rundel
Department of Organismic Biology,
Ecology, and Evolution
University of California, Los Angeles
Despite their otherwise high species
richness of vascular plants, the five mediterranean-climate regions of the
world are relatively poor in their diversity of fern species. We have
hypothesized that this low diversity relates to ecophysiological problems
of adaptation to summer dry mediterranean-climate conditions, especially
with regard to the degree of stomatal control present under exposure to
high vapor pressure gradients. It is not clear, however, whether, it is
the sporophyte or gametophyte stage of the fern life cycles that exert the
strongest limitations for survival. We are carrying out photosynthetic gas
exchange studies with four species of native ferns.

#9.Influence of nutrient loading on the
invasion of an alien plant species, giant cane (Arundo donax) in
Southern California riparian communities.
Gretchen C. Coffman
Environmental Science and Engineering Program
University of California, Los Angeles
Gretchen Coffman is
studying the ecological factors that promote invasions of giant cane (Arundo
donax) in riparian habitats of the Santa Monica Mountains. Her research is
focusing on field and experimental measurements of the significance of
nutrient-rich agricultural or urban runoff in promoting growth of arundo.
Her field sites include the Santa Clara River, Calleguas Creek, and Topanga
Creek. Gretchen is a doctoral student in the Environmental Science and
Engineering Program at UCLA.

# 10. The
stability of frequency dependent dynamics in the side-blotched lizard
Ammon Corl (Dr. Barry
Sinervo, Advisor)
Department of Ecology and Evolutionary Biology
University of California, Santa Cruz
One of the most common
mechanisms for maintaining phenotypic and genetic diversity is
frequency-dependent selection. However, few studies (if any) have studied
frequency dependence across multiple populations and through evolutionary
time. The side-blotched lizard (Uta stansburiana) is ideal species
for the study of the maintenance a frequency-dependent system. A population
of U. stansburiana at Los Baños Grandes, California maintains three
different male morphs through frequency-dependent selection and two
different female morphs through density- and frequency-dependent selection.
The frequencies of both the male and female morphs cycle over time. My plan
was to reconstruct the evolutionary history of U. stansburiana in
order to understand how the frequency-dependent population dynamics of the
species has arisen and changed through time. The goal was to find
populations of side-blotched lizards, mark a large number of individuals,
and to score each individual for their throat color. Throat color scores
provide preliminary indications of the behavioral strategies in each
population. At Stunt Ranch, the lizards are found up the fireroad going up
into the Santa Monica Mountains. The highest densities are found at the
crossroads of trails (near where there is a bench). Other species in the
area are whiptails, Western fence lizards, and a kingsnake. I was looking
for the presence or absence of genetically determined behavioral morphs that
are found in the side-blotched lizard. Preliminary evidence indicates that
the morphs are likely to be found at Stunt Ranch.

#11. The response of
pollinators to hybrid arrays of Penstemon centranthifolius and Penstemon
spectabili
Paul Wilson,
Elizabeth Jordan
Department of Biology
California State University, Northridge
Penstemon centranthifolius and Penstemon spectabilis grow
together in the Santa Monica Mountains, and very occasionally produce F1
hybrids. Parents and F1s were observed near the Reserve, but not on it.
Artificial backcrosses in both directions, F1s and both parents were grown
in pots. A linear relationship was found between parentage and many floral
characters, including the amount of nectar produced. Parents, F1s and
backcrosses were places in a 5 x 5 array on the Reserve. Pollinators were
allowed to forage. Ceratina
bees
preferred P. spectabilis over P. centranthifolius.
Hummingbirds preferred P. centranthifolius over P. spectabilis.
Hybrids tended to be treated by the animals like one parent or the other.
The response was not linear, rather it had a threshold to one side or the
other of the F1s. In order to test the hypothesis that nectar is the primary
reason why
hummingbirds prefer P.
centranthifolius, we added 5 uL of 19% sucrose solution hourly to P.
spectabilis and the backcrosses to P. spectabilis. This tended to
equalize
hummingbird preferences
between P. centranthifolius and P. spectabilis. The F1s that
were not augmented continued to be undervisited.

# 12. Rainfall variation and persistence
of native plant in exotic grassland
Jonathan Levine and
Heather Coleman
Department of Organismic Biology, Ecology, and Evolution
University of California, Los Angeles
This work is based on a
largely unanswered question in ecology, namely how rare species persist in
the presence of superior competitors, effective colonizers, and
well-defended counterparts. When examined on a population level, it would
seem that rare species are threatened by environmental fluctuations, as less
favorable conditions could substantially reduce their already low numbers.
However, we hypothesize that community level analysis might reveal the
benefits of variable environmental conditions for rare species. For example,
the possession of a seed bank allows rare species to remain dormant
throughout less profitable years and maximize their success in the eventual
presence of favorable conditions. In order to establish the importance of
unfavorable growing conditions in rare plant persistence, we manipulate
rainfall as a proxy, since Southern Californian plants are mainly limited by
their water supply. We are currently providing half of the plots with more
water than average. We also control the amount of litter covering plots, and
remove exotic grass competitors. Finally, we are excluding grazers from half
of the plots as well. Our goal is to understand the impact of variable
conditions on native plant communities in Southern California, thus
providing valuable information relevant to the management of these rare
species and to diversity preservation in general.

PHILIP
W. RUNDEL
Reserve Faculty Director: Philip Rundel is a professor in the
Department of Organismic Biology, Ecology, and Evolution, at UCLA. He is a
former UCLA representative to the UC Natural Reserve System Advisory
Committee. Rundel has a broad research program involving a variety of
aspects of plant ecology and ecophysiology, with a special emphasis on
chaparral ecosystems of Southern California and warm desert ecosystems of
the Mojave Desert. Field works centers on studies at Stunt Ranch and in
the desert at the Sweeney Granite Mountains Reserve, Edwards Air Force
base, and the Fort Irwin National Training Center. In March 2002 he
presented an invited paper at an international conference, "Promoting Best
Practices for Conservation and Sustainable Use of Biodiversity of Global
Significance in Arid and Semi-Arid Zones", in Santiago Chile. In addition
to these studies, he continues an active program of research on the
ecophysiology of plants in tropical environments. This research involved
field studies at the La Selva Biological Station in Costa Rica in January,
and he mentored an undergraduate student from the University of New Mexico
in a La Selva NSF program in Research Experience for Undergraduate
Students. Rundel has also been appointed to the Research Committee for the
Organization for Tropical Studies, a consortium of universities and
scientific institutions that sponsors international research and education
programs on tropical ecology. Other administrative activities in the past
year have included serving on an NSF panel reviewing proposals for
Integrated Graduate Education and Research Training (IGERT), and similar
efforts in Brussels reviewing research programs in global change ecology
and desertification for the European Union.

CAROL
FELIXSON
Reserve Director of Education and Community Outreach: In
addition to her work for the Stunt Ranch Reserve, Carol Felixson also
serves as the docent and communications coordinator for the Mildred E.
Mathias Botanical Garden (MEMBG) at UCLA. Felixson writes Carol’s Corner,
