Center for the Study of Plant

Conservation

The Garden enters the twenty-first century with anexciting new role in research on plant conservation sponsoredby the University of California. Research will focus on plantsfrom Mediterranean-type climate regionsin particular, thequintessentially California bioregion described in The JepsonManualas the California Floristic Province. Encompassingthe area west of the Sierra Nevada Crest, extending intosouthwestern Oregon and northern Baja California, thisbioregion is familiar to us through its defining feature of cool,

wet winters, and hot, dry summers. To conduct research, theGarden will begin construction this winter of the Center forthe Study of Plant Conservation, and next summer, we willerect associated greenhouses. Why make the study of theMediterranean-type climate a keynote for the new century?

In five areas within earths temperate latitudes,Mediterranean-type climates are caused by cold waterupwelling along the western coast. As the summers are dry inthese climatic regions, plants grow mainly during the cool,winter season, whereas plants in the worlds other bioregionshave adapted to grow during the warm season. As a result,

plants in regions with Mediterranean-type climates sharemany similarities. For example, most montane regions in thenorthern hemisphere share common plant species or genera,and almost all are perennial.

The coastlines that make possible this distinctivebioregion will, however, experience enormous populationpressures over the next 50 years. This year, the global humanpopulation reached 6 billion, and the United Nations projectsthat over the next 50 years, we may add nearly 4 billion morepeople. Two-thirds of the worlds human population nowlives within 100 miles of an ocean, inland sea, or freshwaterlake, while fourteen of the worlds fifteen largest megacities

under moderate to high pressure from humandevelopment, Mediterranean-type bioregions will experiencedirectpotentially traumaticimpact from our activities.

Despite the risks, Mediterranean-type bioregions have

not thus far been targeted for protection. Unlike rainforests(which seem exotic and charismatic due to distance), weexperience Mediterranean-type bioregions as familiar, evenmundane. There is no Save the Mediterranean-TypeClimate Zones organization. We dont even have aMediterranean-Type Climate Zones Action Network.Yet the biota of these regions is no less special than thoseof the rainforest.

To lead in assessing the risks to biodiversity inMediterranean-type bioregions and to develop conservationstrategies, the Garden will begin by building the Centerfor the Study of Plant Conservation. The Centers core of

a support area for large equipment, and a computer lab.In addition, the Center will house a plant growth facility,including growth chambers, a headhouse for potting andharvesting experiments, an outdoor research garden andresearch greenhouses featuring computerized climate controland monitoring. As studies repeatedly show how socialinteraction fosters intellectual creativity, the entire Center willbe designed to create opportunities for intellectual exchanges

among scientists. There will be offices for nine resident andvisiting scholars and students, a conference room, and alunch room.

This environment will be especially crucial toaccommodate two kinds of researchbasic research, drivenby intellectual curiosity, and applied research, directed towardconserving the biodiversity of Mediterranean-type bioregions.The scientific enterprise thrives best when scientists pursuebasic and applied research simultaneously. Basic science can,for example, yield unforeseen dividends for applied scienceas illustrated by our research on lupine populations at theBodega Marine Reserve. The dramatic and rapid changes inshrub density suggests that seed consumption by deer miceplays an important role in the population dynamics of theseshrubs. Recently, however, when we expanded our research tothe lupine populations at the Lanphere Dunes Unit of theHumboldt Bay National Wildlife Refuge, we learned thatlupines had become invasive weeds. Introduced at the turn ofthe century to stabilize coastal sand dunes, they now over-runthe diverse, attractive native dune mat vegetation. Sinceinsights from our Bodega Reserve research points to theimportance of deer mouse feeding behavior on lupinepopulations, our basic science research help us to understand

the invasive lupines of the Lanphere-Christian Reserve. Totest this hypothesis, we are currently running experimentsthat will inform future management decisions.

The Gardens Center for the Study of Plant Conservationmay ultimately develop many bioregional management

strategies for Mediterranean-type climate. In the past,conservation efforts tended to protect small patches of land tosave particular target species, but these preserves have oftennot proved sustainable. For example, biotic communitieschange through time, often in a relatively predictablesequence called ecological succession. When a target speciesthrives only in one stage, it becomes vulnerable todisturbances that affect the preserve, whether they are as

minor as a trees falling or as major as a fire. After adisturbance the ecological succession is reset, and the targetspecies must migrate to other patches at the optimal stage forits survival. Yet if a preserve has become an island in anuninhabitable urban or intensive agricultural matrix,opportunities for the migration of the target species suffer.Moreover, such small preserves are unusually vulnerable tochanges outside the preserve, such as invasive species orreduced air or water quality.

Further research is needed to improve managementstrategies, prompting biologists and managers to join withother professionals to attain a more complex goal: bioregionalmanagement of biodiversity. Within this context, scientists in thetwenty-first century will include humans and our activities withinthe natural world, thus enabling us to consider and manage forthe integrated effect of our activities upon biodiversity.

Living in the Bay Area, we are acutely aware of thecomplexities and trade-offs inherent in preservingbiodiversity, while accommodating human needs. TheGardens Center for the Study of Plant Conservation willaddress these issues by taking the following steps:

1) forming an international network of botanical gardensand arboreta to coordinate research on managing the biota of

Mediterranean-type regions;2) facilitating and participating in interactions among thenumerous parties who affect and benefit from these bioregions;

3) publicizing the value of these regions and the risks theyface; and

4) educating the publicabout how to managethese regions to preservebiodiversity, whileaccommodating theinevitable human growth.

In the meantime, the

Garden looks forward tobuilding the Center for theStudy of Plant Conservationto meet the new challenges ofpreserving the biodiversity ofour own Mediterranean-TypeBioregionwe invite you tojoin us in watching theconstruction of the newbuilding!

Built in the 1930s, the Desert-Rainforest House is slatedfor demolition this winter as part of the Universitys campus-wide deferred maintenance program. A new greenhouse willbe built on the same foundation footprint as the currentgreenhouse. Interestingly enough, this exact spot was the site

of the cowshed when the Garden was a dairy farm.As of press time, we are planning to build a temporary

structure adjacent to the parking lot to house the DesertCollection during construction of the replacement house.The construction is due to begin in the spring.

More Renovations at the Garden

The long term renovation of African Hill project hasmade great strides with horticulturist Lawrence Leeoverseeing the planting of some new accessions.

Plant accessions had become so hybridized and weedythat they had to be removed from the African section. Rocksare being reset to accommodate new plantings. In the futurea variety of succulents, bulbs, shrubs and annuals will beplanted to demonstrate the amazing diversity of SouthAfrican flora.

Lead Building Maintenance Worker Gerald Ford recentlycompleted the renovations to the Gardens carpentry work-shop in the corporate yard. The workshop now has a highroof designed to allow better conditions for working withlonger pieces of wood. The 30 year old shingle roof was a

particular challenge Gerald notes!The renovated workshop is the first part of a plan to

upgrade the corporate yard. Future plans include: upgradingthe electrical system, a major drainage project designed todivert rain water run-off away from the Mexican and CentralAmerican area, the addition of storage units and relocation ofthe staff lunchroom to the Barn.

given on topics of resources for restoration efforts, botanicalnetworks, research on plant genetics, seed research, andrelated subjects. Participants attended from Australia, Canada,England, India, Italy and the U.S. One of the sponsors of the

symposium was the Center for Plant Conservation (CPC), ofwhich the Garden is a participating institution. The CPC isthe only national organization dedicated exclusively to theconservation of endangered plants native to the United States.The information presented during the symposium has directapplication to the Gardens plant conservation activities. Forexample, the impact of seed collection on a population of rareplants in Florida was studied over a period of years and theinformation was used to plan seed collection at a level thatwould not negatively impact the population. Holly alsoattended the national meeting of the CPC held in October,hosted jointly by the Chicago Botanic Garden and the

Seed Exchange List

The Gardens Seed Exchange Listis made available to over600 botanical and other research institutions world wide forresearch and display purposes. The last issue of the seed listwas published in 1998 in which we offered 144 collections.From those collections we filled 1,980 orders. The Gardenreceives, on average, 30% of all new accessions throughexchange of seeds with other institutions.

Seeds of California natives which are wild-collected are ingreat demand. Holly Forbes and horticulturistsRoger Raicheand Chris Carmichael traveled in northern California inmid-October collecting seed of California native plants forthe upcoming exchange list.

The Garden recently received generous support towards

part of the cost of producing our Seed Exchange Listfrom theDonations Committee of the East Bay Chapter of theCalifornia Native Plant Society, for which we are grateful.The Garden has a long and special history with this chapterand greatly appreciates the members interest and supportnot just for the seed list but for many Garden activities.

If you are interested in helping to support this aspect ofwork here at the Gardenand it really is work essential togrowing our collectionthen we would be delighted to hearfrom you, please call Janet Williams in the Developmentoffice at 643-2937. If you have any questions about the seedlist itself please contact Curator Holly Forbes, at 643-8040.

GARDEN NOTES

Congratulations to Garden Faculty Advisory Committeemember Nan Crystal Arens, who received a 1999 HellmanFamily Research Grant, established by Warren Hellman tohelp junior faculty at a crucial stage in their careers.

Distinguished visitors to the Garden recently include: Dr. Eric Hgsater of the Herbario AMO in Mexico

City (herbarium of the Asociacin Mexicana deOrquideologa) visited the Garden August 12, 1999.He was able to identify several orchids in the generaEpidendrum and Encyclia.

Dr. Wolfgang Bopp, Curator of the newly developingNational Botanic Garden of Wales visited October 13.Dr. Bopp was very interested in our Mediterraneancollections, as that is the theme of the new garden inWales. They have built an enormous glass house in

which to showcase plants from the five Mediterraneanclimates areas of the world.

Dr. Yuan T. Lee, Professor of Chemistry emeritus atUC Berkeley, visited the Garden October 29 andmet with Curator Holly Forbes. He is interested indeveloping a conservation component at a proposedbotanical garden in Taiwan.

Faculty Curator Dr. Robert Ornduffattended the 10thanniversary celebration of the Garden Conservancy inCharleston, South Carolina in October.

HorticulturistJudith Finn attended a Pest ManagementConference in San Rafael presented by UC Cooperativeextension on October 15, Managing New Pests by IPMPrinciples. This included some very worrisome problemsthat are challenging local arborists such as the new epidemicof Oak Bark Beetles and Ambrosia Beetles that arethreatening our California Live Oaks (Quercus agrifolia), RedGum Psyllid Lerp, which is killing Eucalyptus, Bronze BirchBorer, and the progression of fire ants up the coast (Them).

Horticulturists Eric Schulzand Peter Klementattended

the regional AABGA meeting at the Getty Center in LosAngeles. They attended the talks by the building architect,site architect, and garden designer. Additional topics includedwildlife as garden hazards and methods to cope with wildlifeproblems as well as fire safety and irrigation.

Curator Holly Forbes attended the Ex Situ PlantConservation Symposium: Strategies for Survivalhosted by theChicago Botanic Garden in September. Ex situ refers toefforts that occur off-site or out of habitat. Theseex situ research efforts are not meant to replace, but rathersupport, in-habitat conservation efforts. Excellent talks were

EDUCATION AT THE GARDEN

Education opportunities in the Garden are growing inevery area. In addition to the Cal students from biology,paleontology and soil engineering departments who havecome for years, the Garden increasingly has become an

educational resource for other departments and for studentsand faculty from other northern California colleges anduniversities. It is not unusual for weekend visitors to observeclusters of students on class visits. On one Saturday inOctober, students from five different colleges were exploringconcepts as diverse as plant adaptations, landscape design,biodiversity, and esthetics. This Spring the Garden willbecome the weekly classroom for students taking a course increative writing at Cal. To encourage every faculty member atthe University to get to know the Garden better, DirectorEllen Simms gave each one a Garden pass. She invited eachto visit the Garden and discover ways to incorporate our

magnificent collection into their teaching efforts. We arelooking forward to their visits and assisting them in makingour collection accessible to their courses and students.

The primary interpretation of the Garden for pre-collegestudents and the general public continues to be shoulderedby the knowledge, dedication, passion and commitment ofour fabulous docents. On most days, 50-60 children and theirteachers and parent chaperones have eyes, minds and heartsopened to the wonders of plant life, ecology, biodiversity andethnobotany by the stories, activities, props and enthusiasmof our docents. We are indeed fortunate to have suchoutstanding educational volunteers. I appreciate their diverseefforts that produce our wonderful programs and service. It isvery simple. Without their efforts, the Garden wouldnt havereached over 14,000 children and adults through tours lastyear. Thank you all, with a special thank you to LindaGovan for her Herculean efforts in making sure that docentsare in the Garden to lead the tours.

Barbara Lyss continues to spearhead our efforts to provideinterpretive material to the thousands of visitors who enjoystrolling through the Garden on their own. Thanksto Alison Mills, visitors have a refreshed, rotating set ofbrochures that highlight seasonal changes in the Garden.We

are looking for funds to expand our publication of brochuresfor the public.

Our outreach programs into the schools now reach over1,000 students and more than 75 teachers annually. Inaddition to one-hour programs, we are now providingteacher training to implement the most recently developedcurriculum unitsBotany on Your Plateand CaliforniaHabitats Alive. Each unit provides 6-8 hours of classroominstruction and related school garden activities. Because theterm botany is not mentioned in the new California StateEducational Standards, teachers are asking for help in findingappropriate fits for plant and gardening activities. As we

work in our four partnership schools and with diverse teachertraining efforts, we understand how we can better supportteachers needs in local school change efforts. For example,while we help teacher Barbara Edwards at Oxford Elementary

School in Berkeley develop a butterfly garden, we are lookingfor ways to give every child at Oxford opportunities toparticipate and learn what is necessary to involve families andthe community effectively in supporting their school.

Such efforts in schools is developing opportunities for theGarden to reach out to audiences who traditionally are notfrequent visitors. On October 2, 1999 the Garden hosted 250students, siblings, parents, grandparents, teachers and theprincipal from its partner school, Lazear Elementary Schoolin Oakland. In order to welcome these families, most ofwhom are Hispanic, docents and Cal students who spokeSpanish greeted them as they arrived and helped with

directions throughout the day. Special thanks go to LeeAnderson our lead greeter, who delighted everyone withGarden history and information about the collection and togreeter international Dawn Keremitsis. We are lookingforward to building on this experience to involve volunteersfrom Lazear in more Garden programming. Brush up onyour Spanish and join us!

Garden Tours in the Desert and Urban Southwest

Fifteen Garden volunteers, some with spouses,participated in the Arizona Sonora Desert Trip forvolunteers. They spent a whirlwind six days in the Arizonadesert in September with Horticulture Manager DavidBrunner, who was born and raised in the Tucson area andgenerously invoked his connections and influence to provide

the widest possible spectrum of experiences for the group.Included in the itinerary were a variety of nurseries,

from huge, wholesale operations to large wholesale/retailestablishments, to small, select, specialty ones.

The UCBG group was received everywhere withincredible warmth (not to mention that temps were usually inthe 90s) and hospitality. We visited private gardens as well asthe Arizona-Sonora Desert Museum, the Tucson BotanicalGarden, the Boyce-Thompson Arboretum and the DesertBotanical Garden. There was even time to visit a fewmuseums and art galleries including Frank Lloyd Wrights

Taliesen West and, for the determined shoppers in the crowd,to shop.

A highlight was a trip up Mt. Lemmon in the SantaCatalina Mountains east of Tucson. The group climbed toabout 9,500 feet, ascending from the forest of giant Saguaros,through the northernmost fringe of the Sierra Madreansavannas, up through Blue and Silver Oak woodlands,beyond Pleistocene-relict Arizona Cypress forest, pastPonderosa Pine montane forest, into Canadian Spruce andFir forests and finally to the Sub-alpine Firs near the summit.We stopped to botanize in each zone, and marveled at theincredible diversity of everything, on just one mountain. Itwas a splendid, fun-filled adventure!

The UCBG Peerless Public Gardens of Los Angeles tripsaw 16 Garden members, escorted by Roger Raiche andNancy Swearengen, spend two days in November visitinggardens in the Los Angeles area.

We toured the gardens of UCLA on a chartered campustransit bus. Our first stop was the Sculpture Garden, a

greensward punctuated by rows of mature sycamore trees,fringed with groupings of smaller trees and shrubs, andenclosed on all sides by University buildings. Strategicallylocated on the 5-acre site are some 60 contemporarysculptures, all by well-known artists, all donated to theUniversity. It was breathtaking!

Our next stop was in Bel Air, on a street so narrow thatour bus couldnt park. The Hannah Carter Japanese Gardenoccupies a steep hillside site, and incorporates all thesymbolism, fine craftsmanship and impeccable care of atraditional Japanese garden.

Then back to the campus to take a look at the Mildred J.Mathias Garden, UCLAs counterpart of our Garden. Thedominant feature of the Mathias Garden is the creek thatmeanders through it with luxurious sub-tropical plantingsalong its edges.

At the Getty Center group members dispersed to indulgetheir special interests, but reconvened for a tour of the gardenswith Roger. At one point, our group swelled to 30 or more, asother Getty visitors joined us. A highlight was watching thechanging colors of the cactus garden as the sun set. The ranksof cacti seemed to glow as if lit from within.

The following day, we visited the Descanso Gardens,originally a private estate, and then a professional camellianursery. We marvelled at the roses still flowering and thesasanqua camellias already in bloom. At The Huntington,Roger led us on a highlight tour of the gardens and groupmembers had time to peek into the Gallery and the Library.Everyone agreed that exploring peerless public gardens was anexcellent way to spend a couple of days in Los Angeles!

Some creep through the door to the Ornduff Room onthe first Saturday of the month, cradling their sick plantsdiscreetly encased in brown paper bags. Others seem to burstthrough the door with bravado fully expectant that the hugegnarly tree branch they deposit with ceremony will surely bethe most noteworthy of the sick, diseased or dubious

specimens brought in for discussion at this session of theUCBG Sick Plant Clinic. Held here since 1990, the Clinichas become a real tradition at the Botanical Garden.

Dr. Robert Raabe, UC Professor Emeritus of PlantPathology and former AssociateDirector of the UCBG, startedthe clinic about seventeen yearsago on campus as a way ofproviding diagnostic experiencefor his graduate students.Dr. Nick Mills, UC Professor

of Insect Biology joined forceswith Dr. Raabe in 1993 as apermanent part of the volunteerSick Plant Clinic team. Dr. AnneGaybrik, a student and nowassociate of Dr.Raabes, comesalong each month to help outwith the pathology side of things.Between the three of them andthe crew of regulars, there isntmuch hope of a disease goingundetected or an insect

undiscovered; a rare virus or insectcauses great excitement and interestamong those present. The referencebooks and the microscopes are out andin constant use such that Sick PlantClinic attendees are given a thorougheducation about the causes of theirplants malady and how to improve itsgrowing conditionsnot just a quickfix answer about how to save theplants life.

This attention to detail comes as awelcome diversion to some, to others areal bonus they can use in their professional careers, as manyof the regular attendeees are volunteers from the AlamedaCounty Master Gardener Program, devoted to being at theclinic out of interest and as part of their ongoing professionaltraining. Long-time Garden volunteers, Elizabeth Waterman,Emma Connery and Leonard Skinner are usually therehelping out and their input is also much valued by allconnected with the clinic.

No matter who is asking the question though, it does notseem to faze the expertsthe same detailed, patient

Volunteers At The GardenHow Theyve Grown

Behind the Scenes Tour &Directors Tour

On October 20 a number of Garden supporters joinedus for a different look at the Garden. Dr. Ellen Simmslead a group on a Directors Tourwhich traversed theGarden looking not just at specimens in the collection which

illustrated aspects of the Directors work as a plant populationbiologist but also looking at plants she found scientificallyfascinating, or plants that she just plain likes!

This group then merged with another group to attend theMembers Only Behind the Scenes Tourheld in the corporateyard. Guests were led on tours of Greenhouses 1 & 2, the newaccessions nurseries and the actual propagation house itself.This was a rare opportunity to hear about the intricacies of thepropagation process at the Garden as it was explained in detailby our plant propagation expert John Domzalski. JudithFinn, David Brunner and Elaine Sedlack led the other tours

with extensive informed commentary about the plants. Asattendee Gladys Eaton truly a Garden Guardian Angelsaid after the tours, the greenhouses are fabulous but its theenthusiasm from the staff that I just love! After the tours,everyone enjoyed the refreshments on what had to be thehottest October day for quite some time!

We thank everyone who participated and particularlythose docents and volunteer propagators who attended andwent out of their way to let us know that, as docent RamonaDavis put it, despite hanging around the place for all theseyears I really did learn some new thingsit was veryinteresting !

Thirty years ago, there were no volunteers, at least noformally recognized ones, at the Garden. This began tochange in the early 1970s under the aegis of director RobertOrnduff, who recognized the need to enhance the Gardenseducational mission to the community and believed that theway to do this was to recruit volunteers to lead tours.

The first 11 docents graduated from training in 1974. Thisgroup and those who followed included enthusiastic and dynamicleaders who implemented all kinds of schemes for drawingattention to the Garden and supplementing its bare-bones budget.In the meantime, horticulturist Judith Finn began to encourage afew volunteers to help with horticultural chores.

Out of the Docents came the Volunteer Propagators, theearly Friends of the Botanical Garden, and the Garden Shop.

Each initiative attracted new volunteers, who in turn creatednew projects and activities.

Today we have more than 250 volunteers on the roster.Volunteers help the Curator with various projects includingcleaning and packaging seeds for exchange with other gardens andfor sale; volunteers help the Gardens professional propagator;volunteers help arrange and put on our programs and plant sales;and volunteers help staff booths at public information eventsthroughout the community. Our volunteers allow us to do a greatmany things that we couldnt otherwise do. We are very gratefulfor the thousands of hours they give us!

A gardener in the southeast claims that by watchinghorses, cattle and deer feed in a pasture, she noticed thatneither horses nor deer feed in areas where there is horsemanure. Using this information, she experimented in hergarden and found that wherever she placed horse manure(aged, not fresh) around plants, the deer did not eat thoseplants.Mother Earth News176: 10.

Generations ago, Navajos added juniper ash to their foodsas a general practice. It is not known whether this was donefor flavoring or for food value but recent research in Utah hasshown that adding the ash makes up for the lack of calciumin present diets of the Navajos in parts of the southwest. Theash from branches and needles is not only a good source ofcalcium but also of iron and magnesium. One teaspoon ofjuniper ash is roughly the equivalent of the calcium in a cupof milk. Interestingly, ash doesnt add particularly noticeableflavors but when added to cornbread, gives it a gritty quality.

Were half way towards a new thermal transferprinter for the propagation house operations hereat the Garden, for the use of the volunteerpropagators in raising plants for the plant salesand in the New Plants Program! We recently receiveda donation from long time Garden supporters Dr. andMrs. Klaus Dehlinger, towards this printer (total cost$4,000), and thank them for moving us a big stepcloser. This printer would help us to label plants clearlyand with more information. Donations toward thisitem would help a great number of people workingin the Garden.
