Annual Report 1999-2000
 

The most basic rules of the world - the ones we all live by - are ecological rules. These can't be simply studied from books or perceived fully in a classroom or laboratory setting. Whether one is a botanist, a biologist, or an earth scientist, it's imperative to go out on the mountainside, watch the rain fall over a valley, dig into the earth beneath a fallen tree, or wade a creek for cobbles with resources upstream. The best work in the natural disciplines starts with observations in nature. - Ken Norris (1924-1998) Natural Reserve System Founder

Narrative Summary

With the UCLA Stunt Ranch Santa Monica Mountains Reserve commemorating its fifth anniversary, a quote on it’s office wall calendar says it all, “Success is a journey….not a destination.”  

Given that most journeys follow a pattern of ten steps forward, nine back, and so on, the important thing to note is that progress towards one’s goal or mission is being made.

As with all members of the UC Natural Reserve System, the Stunt Ranch Reserve’s larger mission is to contribute to the understanding and wise management of the Earth and its natural systems by supporting university-level teaching, research, and public service at protected natural areas throughout California. On a more local level, the reserve seeks to serve both the UCLA and the Santa Monica Mountains community of visitors, neighbors, landholders, K-12 and university students, researchers and educators as a key locale and focus for environmental education and research.

In addition to the numerous classes and research projects listed in the following sections, some of the landmark footsteps of the Stunt Ranch Reserve journey in the past year include:

- Design and planning of exhibits for the education/nature center: The reserve’s design consultant and directors have been working on the concept, design, and content of both permanent and moveable displays, some interactive, for the proposed education/nature center. The listings and description along with conceptual drawings can be found at the end of this annual report.

- Collection of Stunt family photos and artifacts: Ed Hall, who as a boy was a close friend and neighbor of Ethel and Harry Stunt (brother and sister – who along with other brothers and a cousin homesteaded the property in the late 1880s), has graciously continued to send the reserve various Stunt family photos and artifacts as he unearths them at his current family home in Montana. These items are safely stored in the reserve’s office on campus and will eventually be on display in the education/nature center. Among others, treasured items received by the reserve this year include: an engraved silver napkin ring from Ethel’s years in China as well as a fan with names inscribed in Chinese letters on the fan’s ribs, a standing wooden picture frame, an etched colored glass cup from 1903, a black fur hand-muffler and collar, a small bible inscribed by her beau and given to Ethel at Christmas 1904.

- Establishment of the oral history program: A series of interviews with people who knew the Stunt family and/or were familiar with the history of the Cold Creek watershed was successfully launched during the 1999-2000 academic year. Stunt Ranch neighbors, John Gensley and his daughter Robin Mitchell, as well as Maximillian Sikinger and his wife Carla were the first people interviewed. More meetings in small groupings are planned over the next year. The information gathered will be an integral part of the reserve’s nature center exhibit on the Stunt family and the history of the Cold Creek watershed.

- Formation of the Cold Creek Round Table: At regular intervals in the past year, the reserve joined with representatives from the Mountains Restoration Trust, National and State Park Services, Resource Conservation District of the Santa Monica Mountains, Santa Monica Mountains Conservancy, and L.A. County Supervisor Yaroslavsky’s office to form the Cold Creek Round Table. This is an informal coalition of agencies who share an interest in the protection and monitoring of the Cold Creek watershed. Numerous issues have been identified, roles explored, and cooperative research and educational projects initiated. One of these is a white paper written by Dr. Phil Rundel, reserve faculty director, titled, “ The Cold Creek Watershed of the Santa Monica Mountains as a Regionally Significant but Fragile Natural Ecosystem.”

- Website posting of K-12 Teaching Guides: The Cold Creek Docents, an affiliate of the Mountains Restoration Trust, provided materials for K-12 teaching guides now posted on the reserve’s website with stylish format and illustrative material. This project was coordinated and produced by Tim Bradley and Marjorie Lynn Patrick of the Department of Ecology & Evolutionary Biology, UC Irvine, and was funded through a grant to the Natural Reserve System from Chevron. See http://nrs.ucop.edu/Reserves/stunt.html.

- Hosting of  events: For the second year in a row the Department of Organismic Biology, Ecology, and Evolution held its annual gathering at Stunt Ranch. This year as last, El Tapitio – the best taqueria in the west San Fernando Valley, catered the party. An Afro-Cuban group of musicians and dancers from the UCLA School of Ethnomusicology performed to everyone’s delight.  The UCLA Alumni Association in co-sponsorship with the reserve held a “Bruin Day in the Country” at Stunt Ranch. In addition to a delicious box lunch, guests were treated to a series of educational and entertaining presentations by reserve faculty and researchers. This event was such a success that another was held in October 2000. The Society of Environmental Journalists also visited Stunt Ranch on one of the scheduled field trips during their annual conference held this year at UCLA. At all of these memorable events, the Cold Creek Docents graciously led hikes and activities for kids of all ages.

- Joint sponsorship with the UCLA Science Project of a biology field course for high school teachers and students: Funded through a UC Natural Reserve System grant from the UCOP School/University Partnerships program, five high school teachers and seven high school students participated in the design and execution of independent field projects. This course was taught both on campus and at the reserve under the direction of Dr. John Lambrinos, Department of Organismic Biology, Ecology, and Evolution, and Adelina Alegria, Graduate School of Education and Information Services.  A specific goal was to develop skills and strategies for conducting inquiry-based field and classroom projects focused on the ecology of southern California and the conservation issues relevant to it. The heart of the course was the development of “take away” field projects and activities using Stunt Ranch as a model system. Teachers and students came from secondary schools in the UCLA Collaborative Outreach Programs.

- Participation in annual Biology Research Symposium: The symposium, comprised of 22 poster presentations and 44 researchers provided a setting for undergraduates, graduate students, faculty, and postdoctoral fellows to present the research that was conducted over the past year and to provide a unique opportunity for them to become acquainted with each other and with the ongoing research work of the department. In addition, field sites affiliated with the department, such as the Stunt Ranch Reserve, were showcased. The reserve directors introduced Stunt Ranch to those who had not yet visited there and encouraged those who had to return. Posters depicting research and educational activities at Stunt Ranch were displayed and reserve literature made available.

-Writing of a chapter in the Southern California Environmental Report Card 1999: Dr. Phil Rundel, reserve faculty director, wrote the chapter on Wildland Fire for the UCLA Institute of the Environment’s 1999 annual report card. He discussed the nature of chaparral fires and gave a history of fires particularly at the urban/wildland interface typical of the Santa Monica Mountains. He discussed fire behavior and fire management policies as well providing an assessment and grade. Rundel felt that previous efforts in wildland fire management deserved a “D” and that in recent years the overall program of wildland fire management improved markedly, now earning a rating of “B”.

- Participation in Earthday at UCLA 2000: The reserve joined university and community environmental groups at a day-long event on Bruin Walk (on the UCLA campus) whose purpose was to focus attention on the environment. Some booths offered organically grown food and beverages, others devised games out of recycled materials, others offered literature/bumper stickers publicizing environmental causes, and still others recruited visitors to join conservation organizations and participate in upcoming events. The reserve’s booth was primarily informational in nature and encouraged faculty and student use of Stunt Ranch for research projects and class outings.

- Coordination of Eco-Heroes program at reserve: Twice, under the leadership of the Eco-Heroes project associated with the UCLA School of Public Policy, high school students came to Stunt Ranch to participate in conservation projects and educational programs. On one visit with the help and guidance of the Cold Creek docents, students learned about, identified, and cut down a variety of invasive/exotic species. On another, they learned about trail maintenance – why it is important and how it is done - and they cleared a connector trail from the educational zone of the reserve to the Stunt High Trail. After each project, the docents demonstrated and taught students to make “friendship” bracelets out of raffia (straw) and colored beads. For many students, this was a first time experience at the urban/wildland interface. While they worked hard, they also had a good time – singing and kidding with each other. The reserve thanks Linda Palmer and the Santa Monica Mountains Trail Council for the use of its equipment on both of these occasions.

- Attendance at the UC Natural Reserve System management meeting: Phil Rundel, reserve faculty director, and Lisa Pompelli, reserve design consultant attended the annual meeting held last year at the Bodega Marine Reserve. The meeting is held at a different reserve each year. It provides a much needed opportunity for the NRS family of reserve managers, faculty advisors, and NRS directors and staff to gather and share with each other scientific as well as administrative updates. Issues are addressed that impact individual reserves and the system as a whole. While topics vary from year to year depending on the needs/requests of the attendees, sessions generally include: an introduction of the facilities and research/education activities at the hosting reserve, NRS systemwide updates (the directors report, and special projects updates), select presentations and panel discussions, field trips of the host reserve, individual reserve reports, and a fair amount of fun and socializing.

- Formation of Stunt Ranch Reserve Faculty Advisory Committee: the reserve directors are pleased to now have assistance from a dedicated group of faculty who share their vision and provide leadership from a variety of perspectives. The newly formed faculty advisory committee include: Philip W. Rundel, Chair: Professor of Biology, Richard F. Ambrose: Associate Professor in the UCLA School of Public Health’s Department of Environmental Health Sciences, Jeanne Arnold: Professor of Anthropology, Art Huffman: Senior Lecturer of physics and astronomy, Martin Cody: Professor of Biology, and Hartmut Walter: Professor of Geography.

- Publication of news items on the Stunt Ranch Reserve: Articles written by or about the reserve appeared in the: Daily Bruin  (Animal Farm), UCLA Today (Ranch tales, faces emerge from the past), Alumni News – renamed UCLAlumni Magazine (See an amazing Stunt [and] Be an outdoor Bruin).

- Updating of the reserve development plan: The reserve directors have updated the reserve’s development plan. The principal authors of the plan are Phil Rundel, faculty director, and Carol Felixson, director of education and community outreach. It is dedicated to Mildred E. Mathias, UCLA professor botany who was one of the founders of the Natural Reserve System. The report addresses: the need for environmental research and teaching sites, a description of the site and its natural features the Stunt Ranch history, the reserve’s teaching/research/outreach significance, the educational and research opportunities, K-12 educational programs, resource management issues, media/community relations, the reserve’s website, and plans for reconstruction of the facilities that were completely destroyed in the 1993 Malibu fire. (See the attached three-page summary)

- Reserve use: In the 1999-2000 academic year, reserve use totaled 4,800 user days. This reflects the number of times a user came to the reserve. Some came only once; others made two or more visits. Broad categories of use include: students, faculty and staff from UCLA and other University of California or Cal State universities, K-12 students and instructors, and a wide variety of other users.

The reserve is proud of the progress it has made since its establishment five years ago, and which can best be demonstrated by the following comments:

It is obvious that academic teaching and research activities at almost every conceivable level are being undertaken at Stunt Ranch. It is one of the few nature sites in the Los Angeles area that is convenient to a very large population of university and pre-college students. The Institute of the Environment (IoE) research projects includes important studies of watersheds feeding Santa Monica Bay, and the sources of runoff and sediments for the coastal environment. The IoE’s educational activities include class outings to the site as part of our undergraduate curriculum, as well as use of the reserve grounds as a destination for training K-12 teachers under an NSF project led by the IoE.

The department is in the process of building strength in the study of biodiversity, and its generation and preservation. The Santa Monica Mountains and Stunt Ranch, situated on the western edge of the Los Angeles basin, are a living laboratory for examining the impact of disturbance on ecosystem processes at the interface between urban, agricultural, and wilderness areas. It is our intention to involve undergraduates in local field projects that have conservation implications

As a faculty member in the School of Public Health and Director of the Environmental Science and Engineering Program, I am especially cognizant of the research and teaching value of Stunt Ranch. My colleagues and I have taken advantage of the relatively pristine state of Stunt Ranch to provide a critical reference for environmental conditions in the Santa Monica Mountains and elsewhere in southern California. In the area of environmental science, it is essential to have good reference areas for study, and this is particularly important near such a highly urbanized area as Los Angeles.

California State Parks (CSP) and UCLA recognize the need for teamwork. Cooperation and sharing resources are essential for the success of each organization. CSP is interested in exploring university training programs for state park staff on topics about the flora, fauna, natural history, and other aspects of the mountains. CSP and the UCLA Stunt Ranch Reserve share a common goal of providing environmental education to the residents of Los Angeles, particularly inner city students.
 – Daniel Preece

UCLA Stunt Ranch Reserve is the ideal teaching/learning site, a living laboratory and outdoor classroom where students of all ages can observe and learn science directly. Much research as been conducted recently which confirms that experiential education, such as provided at the Reserve, is superior in producing students who learn more efficiently and productively. The UCLA Stunt Ranch Reserve could well become an extremely important base for chaparral related research and instruction in southern California.
 – Nancy Helsley, Director
Cold Creek Docents

The Cold Creek Watershed supports a great diversity of species, many of which are little understood. Increasing the research capability to better understand the Mediterranean ecosystem is a function the Mountains Restoration Trust supports. As the contiguous neighbor of the UCLA Stunt Ranch Reserve, we look forward to a continued cooperative partnership as stakeholders in the Cold Creek Watershed and in the greater ecosystem of the Santa Monica Mountains.  
– Stephen A. Harris, President
Mountains Restoration Trust

Both as director of the UCLA Ocean Discovery Center and as a lecturer for the UCLA Institute of the Environment, the students that I brought to the UCLA Stunt Ranch Reserve consistently found the experience to be educationally valuable whether they were K-12 students or undergraduates. Having worked with inner city school children and teachers at both UCLA and the California Science Center, I know how valuable and important the kinds of experiences that can be gained at a place like Stunt Ranch are. Most of these children rarely get the chance to leave their urbanized neighborhoods.
  – Charles D. Kopczak, Ph.D.,
Curator – Ecology Programs
California Science Center

As the next year unfolds, the faculty director, advisory committee members, and staff are working diligently on the reserve’s journey towards the realization of its goals.  And like their favorite saying goes, “…of all the paths you take in life, make sure a few of them are dirt.”

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

My main research objective at Stunt Ranch Reserve is to investigate the reproductive behavior of the paper wasp species P. aurifer. I am gathering life history information about the annual nesting cycle of this little-studied local species, which seems to be much more flexible than those of species in Northern temperate regions. In particular, I am looking at two aspects of P. aurifer behavior at Stunt Ranch Reserve: First is the high frequency of solitary nesting despite an apparently high nest failure rate, and second is the potential of the first emerging offspring to be reproductives rather than staying on the nest to become workers. I am currently conducting field studies of the nests in wooden nest boxes, which I have placed in grassland areas of Stunt Ranch. Each spring and summer, females build nests in some of the boxes. I mark the individual wasps with unique paint codes and census all nests two to three times weekly from April to August. I also collect DNA samples for microsatellite DNA analysis to determine genetic relatedness of individual wasps as well as maternity of the brood on the nest. In addition to the objective stated above, this data will be used to examine questions about the relationship of kinship to the division of labor and reproduction among nest foundresses and workers.

This research project addressed the level of variation in the song structure of male wrentits in order to find out how stereotyped a bird with a single song is. The importance of variation has been described in terms of avoiding habituation and as fatigue (i.e.: a bird's inability to repeat the same song precisely). I addressed different levels of functionality for song variability by designing playback experiments to address whether or not wrentits cue in on variation and use it in making decisions about territory defense.Wrentits do not respond as aggressively to songs that have extended internote intervals (songs that sound slower). In some respects they respond in the same way they would to normal, unaltered song, but they do not approach the playback speaker as much, indicating that they do not perceive the song as a significant threat.This work was presented as a poster at the 2000 Animal Behavior Society conference in Atlanta, GA.

 

How ecosystem carbon fluxes vary with stand age and disturbance.

Center for Environmental Analysis & Department of Biology and Microbiology (CEA-CREST)

California State University, Los Angeles

Field measurements in the Cold Creek Watershed have been conducted as part of the CEA-CREST project (see http://vcsars.calstatela.edu/crest/crest.htm). The primary goal of the larger project is to see how ecosystem carbon fluxes vary with stand age and disturbance (e.g. fire). An additional goal is to explore the role of plant functional types in ecosystem function. A primary tool of the project is optical remote sensing because our ultimate goal is to develop models of carbon flux driven by remote sensing. This has tested the ability to identify contrasting species and functional types with spectral reflectance. This is done by sampling transects for spectral reflectance and species composition. The project is expected to run through December 2000.

The UCLA study team finished and submitted the final report, entitled "Lower Malibu Creek and Lagoon Resource Enhancement and Management," to the California Coastal Conservancy in May 2000. Field work and data collection was completed last year, and the work during this academic year consisted of data analysis and interpretation and revisions to the draft report. Following submission of the report, Dr. Ambrose has been assisting the Malibu Lagoon Task Force in generating an action plan based on the recommendations in the report. The report also generated considerable interest in the community and has been featured in the radio and print media.

Spectral Mixture Analysis (SMA) from Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) was used to understand regeneration patterns after fire in two semi-arid shrub communities of the Santa Monica Mountains, California: Northern mixed chaparral and coastal sage scrub. Two fires were analyzed, the Malibu Topanga fire (3 November 1993) and the Calabasas fire (23 October 1993). The SMA was compared to the results of the Normalized Difference Vegetation Index (NDVI) to assess vegetation recovery. Anunburned control plot (within the past 20 years), having similar environmental features was employed to generate relative fire regeneration indices, Regeneration Index (RI) and Normalized Regeneration Index (NRI). Indices were calculated using the Green Vegetation (GV) endmember and the NDVI. These indices were determined to be largely independent of AVIRIS radiometric calibration uncertainty, minor errors in the atmospheric correction, topographic distortions, and differences in the phenological state of the vegetation due to inter-annual or seasonal differences. The evolution of the two fires were linked to produce a longer observation period and used to fit a logarithmic regression model for each Mediterranean shrub community. The Normalized Regeneration Index of the Green Vegetation endmember (NRIGV) produced the best estimate for the time of recovery in both communities based on recovery times in the literature. The use of NDVI worked very well for recovery in the Northern mixed chaparral, but was less successful in the coastal sage scrub, mainly because of extensive herbaceous cover in the first years of the regeneration process. Endmembers generated from hyperspectral images were more accurate because they are tuned to capture the greenness of the shrub type of vegetation. Matching plots with similar environmental features that were burned in a fire in a different year was demonstrated to improve estimates of the recovery within each community.

 

Small mammal survey of Stunt Ranch Reserve

University of California, Los Angeles

 A small mammal survey was conducted at Stunt Ranch from August 25-30, 1999 (300 trap-nights). Twenty traps were set each night in each of three transects during this period. The transects included a riparian zone along Cold Creek, in the chaparral on a hillside along the east side of the entrance road, and in an oak woodland on the western hillside behind the Cold Creek Docents nature center. Data collected included: sex, age, transect location, type (new or recapture), reproductive status, date, and weight in grams. Peromyscus maniculatus and Neotoma fuscipes were captured, and possibly a single Pergnathus californicus.

Development Plan Summary

November, 2000
How can anyone begin to understand the dynamics of an eco-system without having crawled through it, or watched the flush of new growth following fire, or listened to the hum of insects and the songs of birds? It is an intricately woven web of life to be seen, heard, and smelled.  -
 Mildred E. Mathias Long time Chair of the UC NRS University-Wide Advisory Committee

The site. The UCLA Stunt Ranch Santa Monica Mountains Reserve became the 32nd member of the UC Natural Reserve System (NRS) in November 1995. This 310-acre preserve is the only reserve managed by the UCLA campus. Of the 310 acres, UCLA and the UC NRS hold the title to 67 acres and have a formal easement for research and educational uses on an adjacent 243-acre portion of State Park land. The reserve lies in the relatively pristine Cold Creek watershed on the north-central flank of the Santa Monica Mountains between Malibu on the south and Calabasas on the north 

Teaching and research significance. The Stunt Ranch Reserve has been developed and managed as a quality educational facility with significant importance to teaching and research activities for UCLA. This use of the reserve includes faculty, research staff and students from academic disciplines across all parts of the UCLA campus and from many other
