One of the strongest forces affecting oak habitat isfragmentation. As habitats are cleared, they leave oak-associated species stranded in biological islands. Frag-mentation of oak habitats reduces their ability to providethe full range of ecological benefits, including mainte-nance of species diversity, soil and watershed protection,and wildlife, recreational, and aesthetic values.

Since oaks are dominant species in a wide range ofhabitats, from grassland to riparian to open woodland,oak habitat in California represents a major portion of thestate's biodiversity. Over 5000 insects, 250 birds, 120

California Oaks — An Ecological Heritagehere are two grand views at the Botanical Garden:to the west, the Golden Gate Bridge across the Bay,and to the east, from the Oak Knoll, a view of most

of the Garden. The Oak Knoll is named for its stand ofcoast live oaks. More than a backdrop for the view, theseoaks are a link to the wild areas, a small piece of Califor-nia native oak habitat, a wildlife corridor for birds andsmall animals.

Of all the native trees, it is the oaks that give Califor-nia its characteristic and well-loved landscape — openand spacious, graced by elegant trees. These trees, aliveor dead, support innumerable insects, birds, reptiles, andmammals in a wide diversity of plant communities. Butlike so many aspects of the environment, California oakshave been taken for granted.

Since 1945, more than one million acres of Californiaoak woodland have been lost, primarily through conver-sion to agriculture and urban development. Thirty percent of the anticipated development over the next tenyears of two million acres in California is projected totake place in oak habitat. Three of California's 19 oakspecies are considered to be seriously threatened. Andoak habitats continue to decline under pressures offuelwood cutting, livestock grazing, range forage im-provement, flood control, and fire suppression.

Year of the OakConsidering these facts and the desire to preserve

California's aesthetic and ecological heritage, the statelegislature has formally declared 1990 the Year of theOak. This proclamation will help spur efforts in oak con-servation, education, and restoration. Of even greatersignificance is a supporting resolution that calls for allstate agencies having oaks in their jurisdiction to prepareaction plans for preservation and protection of theseoaks. This includes the Departments of Forestry, Parksand Recreation, and Fish and Game and also Caltrans,prisons, and the University of California. With thisspecific mandate, the 67 types of oak habitat are targetedfor management plans that include more than commer-cial considerations.

mammals, and manyreptiles and amphibians use

and depend on oak habitatfor food, shelter, and breeding

territories. For example, theacorn woodpecker relies almost

completely on acorns for food, andchickadees and titmice use oak cavities for nesting.Urban trees in parks and backyards are part of the oakhabitat mosaic, providing a visual as well as biologicalbridge to the source landscape.

Though oaks have been in California for 20 millionyears, many oak species are markers of refugia, evolu-tionary backwaters in the speciation process. Quercussadleriana has relatives in China and Turkey; Q. engel-mannii (Engelmann or Mesa Oak) is limited in distribu-tion to less than two per cent of the state — primarilycentral San Diego county. Mexico hosts by far a muchlarger number of species, but it is in California thatspecies ranges taper off with topographic and climaticbarriers. Here we find some interesting natural crossesbetween the evergreen shrub oaks and the deciduoustree oaks, showing adaptive genetic response to toughcultural regimes.

Shifting the BalanceIronically, it is both common and rare oak species

that are most threatened. Engelmann Oak and SantaCruz Island oak (Q. parvula Greene var. parvula) alreadyhave limited ranges. The valley oak (Q. lobata) and theblue oak (Q. douglasii), though widespread in the grass-land savannas and foothills, are not regenerating welland suffer from poor timing of cattle grazing. Theapparently abundant coast live oak (Q. agrifolia) isdisappearing at an alarming rate due to rapid urbaniza-tion of its habitat.

In response to the visible loss of local oaks, especiallyin areas named for their oak landscapes (Thousand Oaks,Oakland, Paso Robles), cities and counties are drawingup oak ordinances to regulate removal. Perceived almostas a weed tree in some areas, this perspective is shiftingas the rate of loss accelerates. Next to habitat destruction,the most significant threat to oaks is our lack of steward-ship of existing oaks, both rural and urban. We particu-larly lack understanding about how to maintain oakhabitat in a grazing area.

Raising Oak AwarenessThe California Oak Foundation and U.C. Coopera-

tive Extension have both prepared useful materials forhomeowners and tree-planters. The California NativePlant Society has just published an Oak Action Kit,complete with species accounts, bibliography, and policystatements. These educational materials are invaluablefor concerned citizens who want to participate in oak

habitat restoration. State agencies must now join theseefforts by developing the necessary oak habitat manage-ment plans. The University of California plays a majorrole in research, both through Hastings Natural Reservein Carmel, prime oak habitat for scientific studies, andthe Integrated Hardwood Range Management Program.

Truth be told, oaks are California. These are the treesthat shape almost all our images of this state. Theyprovide the visual and ecological structure for our senseof place. As they disappear, we lose our ties to thelandscape where we live. Oak conservation is an avenueto restoration and good management of a large piece ofthe state's biological heritage. With some foresight now,we can encourage and sustain these lovely trees and theirhabitats for our children to know and love as well.

An Orchid by Any Other Name -Would Be Different!lants, like people, are related and named throughtheir family associations. When it gets down tospecifics, however, we find some curious, even sur-

prising differences. In this case, we'll look at orchids andthe problem of hybrid and cultivar names.

When individuals of two different orchid species arecrossed successfully, hybrid offspring are produced.Considering the thousands of individual seeds in anorchid seed pod, and the possible large number ofprogeny produced by even a moderate percentage ofgermination, the task of naming all these diverse siblingscould become rather overwhelming. World-wide agree-ment by botanists who concern themselves with suchmatters has given us a set of rules to help in our predica-ment. These are published as the International Code of No-menclature for Cultivated Plants (1980), and the Interna-tional Orchid Commission's Handbook on Orchid Nomen-clature and Registration.

The Need for AccuracyWhen two different orchid plants, whether species or

hybrids of whatever complexity, are crossed, any result-ing progeny are identified by a collective name. Thiscollective name or epithet is called the grex epithet. Grex isdefined as a "flock or group, applied collectively to theoffspring of a given cross." The word gregarious comesfrom the same word root, grex. To be technically pure, theexpression "collective epithet" is used when referring tonatural hybrids, whereas orchidists use the expression"grex epithet" for artificial hybrids.

For example, Cymbidium 'Blue Smoke' x Cymbidium'Balkis', a very productive mating, was given the grexname 'San Francisco'. In this instance, C. 'Blue Smoke'was the pod or female parent of the union and C. 'Balkis'was the pollen or male parent. If the roles were reversedso that C. 'Balkis' became the pod parent and C. 'Blue

Smoke' the pollen parent, the grex name would stillremain the same, San Francisco. This convention is quitedifferent from the practice generally followed in naminghuman offspring in our patronymic society.

This particular cross was extremely successful,producing a large number of siblings with excellentflowering characteristics, form, shape, substance, andflower color ranging from pink through white to green.Because of this diversity, the different plants wereconsidered worthy of their own individual names. Theindividuals of a grex are called clones if propagatedvegetatively, and may be given particular names. In thisinstance, we follow the human practice of giving eachseparate offspring a distinct (i.e. cultivar) name to helpidentify one from another.

A cultivated individual of a species or its wildvariants and its vegetatively produced progeny (i.e. aclone) may be identified by adding a cultivar epithet to itsname. A cultivar epithet is a fancy name (i.e. not neces-sarily in Latin form) in Roman print, starting with acapital letter and enclosed within single quotation marks.Double quotation marks must not be used. Although theanalogy is not strictly accurate, the grex name could bethought of as a family name.

So for these diverse offspring, we would haveCymbidium 'San Francisco' (the nontechnical "family"name) with individual offspring (cultivars, clones)named: 'Angelica' (yellow in color), 'Florence' (white),'Kathleen' (green) 'Powder Puff' (pink), and so on. Thename 'San Francisco' is not enough; to know an individ-ual plant, it must bear the entire name. Just as it isimportant to label wild-collected species properly torepresent relationships accurately, so also is it critical thatcultivars be properly labeled. "By any other name, itwould be different."

The Garden Moves to Strawberry Canyon

T. Harper Goodspeed surveys the collection of cacti and succulents in the 1930s.

Editors note: This is the second of three articles in a series by Lincolnconstance, Professor of Botany Emeritus, on the history of the Botanical Gardenover its first one hundred years. Supplemental information was drawn fromHerbert Baker's article, "The University of California Botanical Garden; theFirst Half-Century" in Pacific Horticulture, Spring 1980.

n the early 1920s, the University of California atBerkeley was expanding at a rapid rate to meet theeducational needs of a growing state and regional

population. The shortage of building space threatened theBotanical Garden's very existence. Under the guidance ofT. Harper Goodspeed, the Garden was successfully movedto Strawberry Canyon where it could expand. Here, hesaid, "the eastward moving air draft from the Golden Gate... with consequent moderating influences on summertemperature and humidity permit an association of plants,birds, and mammals not duplicated elsewhere in middlewestern California."

The Goodspeed YearsAlthough not officially named Curator of the Garden

until 1926, it was Goodspeed who planned the Gardenwith assistance from J.W. Gregg, professor in the Depart-ment of Landscape Design, and supervised its constructionin the mid-twenties. In departure from traditional botani-cal gardens, Goodspeed decided to group the collectionsprimarily by geographic regions. Over the course of hislong tenure as Director (1934-1957), he developed signifi-cant collections for the Asian area, South American area,African Hill, and the California Native area.

One of the first major acquisitions of the new gardenwas a notable collection of rhododendrons purchased for

Rhododendron Dell by a group of dedicated alumni andfriends. (See Garden Spotlight, pages 8-9.) The expansioninspired a major expedition in 1932 to the distant forestsof western China, organized and led by Dr. Joseph F.Rock. This beginning of a botanical relationship withChina was furthered later in the 1940s by another expedi-tion to Szechuan Province. On this trip, Dr. RalphChaney, paleobotanist, brought back rare samples of thenewly discovered Dawn Redwood (Metasequoia glyp-tostroides). Five individuals now grace the upper creekcanyon, and countless others have been propagated anddistributed from UCBG cuttings.

But in 1930, most of the Strawberry Canyon gardenwas occupied by row upon row of head-high tobaccoplants. This assemblage represented all the known wildand cultivated species first established by WilliamSetchell. Soon after this, Goodspeed launched a series ofbotanical expeditions to the Andes to further augmentthe collection of Nicotiana. These expeditions broughtback a wide diversity of plant material, much of whichwas distributed to other gardens around the world.

The first Andean expedition also brought a numberof succulents and cacti which were established in anextensive rock garden by James West (Prince Egon VonRatibor). From the beginning, New World plants werekept separate from African succulents to provide anexcellent demonstration of convergent evolution. Thelargest single collection of southern African succulentswere collected by Robert J. Rodin as part of the Univer-sity of California African expedition in 1947-48. A sev-enth and final expedition to Chile and Peru in the 1950s,under the leadership of Paul Hutchison, senior gardenbotanist, brought back nearly 500 living plants for thisarea. This collection came to be well known to the public,

and photos of the Garden's succulents appeared regu-larly in tourist brochures put out by Berkeley CityCouncil and the Chamber of Commerce.

During much of the Goodspeed era, the Garden wassupported by very strong horticultural connections.Prominent horticulturists such as James Smith, presidentof San Francisco's King Coal Company, made the devel-opment of Rhododendron Dell possible. The HerbGarden was cared for by members of the Herb Society ofAmerica. There was a large orchid collection and anextensive Rose Garden of both wild-collected species andcultivars. Garden staff introduced a number of poten-tially important ornamental plants into the nursery trade,including Lapageria rosea and Camellia reticulata 'CaptainRawes'.

Much of the grounds clearing and trail building wasaccomplished by a large CCC crew (Civilian Conserva-tion Corps) assigned to Strawberry Canyon for sixmonths. Over 200 young men from Nebraska and Mis-souri built check dams, constructed roads, and thinnedthe young tree plantations in the adjacent "primitivearea" (now designated an Ecological Study Area). Thiswork established the context for the Garden we knowtoday— a forested canyon, protected from furthercampus development in the immediate vicinity.

The Baker YearsGoodspeed announced his official resignation in

1954, having made a major contribution of a lifetime tothe garden. At the time there was some possibility thatthe Garden might become detached from the Departmentof Botany. Fortunately, Goodspeed agreed to stay on asActing Director while the University debated whetherthe Garden was an unaffordable luxury. The departmen-tal bid was accepted and in 1957, Herbert Baker,professor in Ghana at the time, was hired as professor ofBotany and the next Director.

During the Goodspeed years, thelack of staff and space had presentedserious constraints for growing re-search and instructional material in theGarden. Baker was asked to activelyinvite more extensive campus use ofthe garden, and soon it began to fulfillGreene's vision as "one of the mostgenerally appreciated ornaments ofour institution." The supply of teach-ing materials to classes in Botany andBiology increased seven-fold, includ-ing samples from a new collection ofeconomic plants.

At this time, plants of horticulturalorigin, often cultivars, were systemati-cally replaced with wild-collected

specimens of higher research value because of theirknown origin and native genetic stock. The seed ex-change with other gardens was expanded and manyareas of the garden further improved. An Australasianarea replaced the existing Rose Garden, a Mexican areawas created, and the California native area expanded.From 1960-1969 the American Iris Society maintained aRegional Test Garden at the south end of the Garden.Three additional greenhouses were established — onenew, one from campus, and a third acquired as a mere$1.00 gift from the U.S. Navy.

Natural DisastersThe years 1961 and 1962 saw every kind of catastro-

phe except fire and earthquake. In summer 1961 therewere two days of 105°F heat, and Monterey pine coneswere opening with "cracks like rifle fire"; a number ofother plants burned. Then, severe frosts and strongwinds in 1962 killed many South American plants andAloes on African Hill. Later that fall, 15 inches of rain fellin three days and Strawberry Creek was flooded, sweep-ing away all the plants along its banks and completelydestroying the pool area in Rhododendron Dell. Treetrunks, shrubs, masses of rock and silt were carried downthe canyon in the raging torrent.

Despite these natural disasters, the Garden was ingood health, well supported financially by the College ofLetters and Sciences. Baker obtained agreement on anumber of minor capital improvements, including thereplacement of the old Tropical House. It was a period ofsteady progress and stabilization of the collections. Aftera dozen years, Baker resigned as director to give moretime to his own research and a growing cadre of gradu-ate students. The garden was now in a position tobecome a major educational resource for both the Univer-sity and the East Bay community.

Plant Clinic Comes to the Gardenrouble with aphids? Leaves turning yellow andyou don't know why? Strange fungi emerg-ing from your potted plants? Bring your sick plant

to the Plant Problem Clinic, now being held the firstSaturday of every month at the Garden Meeting Room.From gam-12noon, an entomologist, plant pathologist,and/or a Master Gardener will be on hand to answeryour questions about plant diseases and insect infesta-tion. U.C. research assistant Rachel Freeman is coordinat-ing the clinic with help from the Master Gardenerprogram.

The Plant Clinic has a history in the College ofNatural Resources as a community service. It was heldoriginally every first Friday afternoon of the month at theGill Tract. Ten years ago, Dr. Robert Raabe, AssociateDirector of the Garden, started the program and kept itgoing until the clinic room was lost to office space. Theclinic was not only helpful to the public, but it providedan opportunity for students to learn plant disease diag-nosis through experience. In today's scientific worldwhere most emphasis is on basic research, there isrelatively little chance to gain information about suchapplied topics as plant pathology. This clinic providesone avenue for understanding practical problems withraising plants.

A Plethora of PathogensIn an interview surrounded by test tubes and slide

carousels, Dr. Raabe explained the types of plant prob-lems, most of which can be diagnosed by visual inspec-tion, microscopic examination, or laboratory culturing.Setting aside insect-caused damage, fungi account for 60-75% of the diseases we see in plants. Molds, mildews,rusts are all in this infinitely variable group, with organ-isms ranging in size from one cell to the large woodybracket fungi that grow on trees.

Bacteria are the next most important cause of plantdisease. As high temperature organisms, bacteria find thetropics more conducive to growth than the temperatezones. Because bacteria have no means of entering aplant on their own, they can only enter through naturalopenings or wounds. Over 400 species account fordiseases worldwide. Familiar diseases include soft rot,the slimy stuff on your old lettuce, and fire blight whichattacks pears, loquats, and Pyracantha.

Viruses are responsible for about 15% of plantdisease problems, but this is the toughest 15%. There isno way to treat viruses except by heating the plants inwhich they are found to 100° before propagating fromthe plant. However, this only works with small cuttings.Sometimes the top few cells can be lifted off the plant in aprocess called "meristemming" to get a clean source.Miraculously, entire plants can be grown from just thesefew cells!

Making Peace with PestsDr. Raabe's philosophy about plant pests is refresh-

ing and unusual; it is his research passion and life'swork. He figures that pests and diseases are here, justtrying to exist in unique and creative ways. Why notlearn to accept them and acknowledge their part in thewide range of biological wonders? Why not simply enjoythem? You might consider this approach the next timeyour peach tree has curl leaf or you find root rot in yourcoast live oak. It's nothing personal, after all; thesesmaller tykes are just trying to survive like everythingelse. Why not appreciate them?

A Campus TreasureDavid P. Gardner, President of the University of

California sent these words of congratulations: "Onbehalf of the University of California community, I ampleased to send greetings to the friends of the BotanicalGarden on the occasion of the Garden's one hundredthanniversary. For the past century, the Botanical Gardenhas been regarded as a campus treasure; it is knownthroughout the Bay Area and the nation as an invaluablenatural and cultural resource.

We are proud that over the years the Garden —through teaching, research, and public service —hastaken the lead in addressing various important conserva-tion issues, all the while serving as a showcase forcountless species and varieties of plants from throughoutthe world, the rare and the common, the unusual andfamiliar. As it begins its second century, the BotanicalGarden will continue to enrich the University and thecommunity as a source of pleasure, learning, and inspir-ing natural beauty. Congratulations and warmest goodwishes on this important milestone."

The Rhododendron Legacy

n the middle of April, when visitors are drawn tothe cascade of flowers at the Botanical Garden, therhododendrons offer their best in beauty and fra-

grance. This group of plants surrounding the JapanesePool and upper Strawberry Creek are some of the best-loved in the Garden. The history of "RhododendronDell" goes back to the very first years at the new site inthe 1930's. From the start it was obvious that the steepshaded canyon would be an ideal spot for exhibitingthese lovely garden aristocrats.

The heart of the Garden's collection comes fromWestern China, Tibet, and the Himalayas where thegenus is widespread and often provides the dominantspecies. In a few acres of the Garden, you can also seeexamples from as far as Burma, Bhutan, Nepal, Kashmir,Szechuan, Eastern Europe, the Alps, and eastern NorthAmerica. Of the over 600 species in the world, theGarden has displayed as many as 250 species.

Mostly lovers of high places, rhododendrons rangefrom about sea level to 16,000 feet in altitude. Theyinhabit steep rocky slopes and open meadows, shadypine forests and sunny mountain thickets. Many of thedwarf species are cliff dwellers, prefering granite ledgesor scree slopes. Others are epiphytic on old forest trees.Though the Garden is only 800 feet in elevation, thenatural shade and wind protection create a favorablemicroclimate for even the high mountain species. Gooddrainage and a slightly acid soil, with overhead wateringas needed, provide excellent conditions for growth. Infact, more species of rhododendron can be grown here incentral coastal California than anywhere else in theworld.

The First CollectionThe earliest UCBG rhododendrons

trace their history back indirectly to theEnglish plant explorer, George Forrest.Forrest was one of the great pioneers inplant exploration at the turn of the cen-tury. Between 1904 and 1931, he madeseven expeditions into the vast riverheadwater country of western China andTibet, searching for undiscovered speciesof potential horticultural significance.Many of his sponsors were especially fondof rhododendrons and one gave Forrest abonus for each new species he broughtback. In total, he discovered or introducedover 300 species of rhododendrons beforehe died in 1932.

Surplus seed from the expeditions wasgiven to the U.S. Department of Agricul-ture and to whomever requested it.Nurserymen Karl Andries and M. Jon-

geneel planted great quantities of this seed, both at SanFrancisco's Golden Gate Park, where Andries wasemployed, and at their Aptos nursery near Santa Cruz. In1930, against the great financial challenges of the Depres-sion, a number of alumni and friends of the Gardengathered together a sum of $27,000 to purchase andmaintain Andries' collection of over 5000 plants forUCBG. This astonishing package included 250 specieswith many varieties and hybrids. Andries was hired asGarden superintendent and rhododendron expert to carefor the new collection. In a single strategic transaction,the U.C. Garden came to house one of the finest collec-tions of rhododendrons in the world.

Plant Hunter Joseph RockShortly after the acquisition of this collection, Aus-

trian born plant explorer and ethnographer Joseph Rockpassed through San Francisco on his way to China.Director Goodspeed showed him the U.C. inventory ofrhododendrons, and Rock became quite interested in thisoutstanding opportunity to develop a comprehensivecollection. He proposed an expedition to the great rivertrenches of the China-Tibet boundary area, offering todonate his services as leader and the use of his collectingequipment. Contributions of support came from severalmajor U.S. arboreta and key donors in Great Britain aswell as Berkeley and San Francisco.

Joseph Rock, a self-taught botanist, had first exploredwestern China in 1921, on the heels of George Forrest andothers. Among other places, he explored the MekongValley and the Salween River, writing, "Never in theworld were there such mountains. We passed through

Spring 1990 Page 9

rhododendrons for days." After several years he returnedto Washington, D.C. to identify some 60,000-80,000specimens forwarded to the Smithsonian Institution. Bythe time he made contact with the U.C. Botanical Garden,he was internationally known for his extensive discover-ies, shared in writing and photographs through theNational Geographic Magazine.

The expedition area proposed by Rock was a bota-nist's paradise. Here in this great corrugated terrain ofthe border area, arose the headwaters of three enormousriver systems — the Yangtze, over 3500 miles long andemptying in the Pacific; the Mekong, over 2500 mileslong and emptying into the South China Sea; and theSalween, which travels 2000 miles in Tibet and Burma toempty into the Bay of Bengal. The three watercourseshave cut parallel trenches through the Himalayas, allwithin an east-west distance of 50 miles. Not only is theflora immensely diverse in this single remote region, butit is an unusual meeting ground of species from thenorthern Old World and Southeast Asia. The wealth ofspecies offered great promise that many would be ofornamental value.

The expedition was not a disappointment. Rockreturned with 163 species of rhododendrons, over 25,000sheets of herbarium specimens, hundreds of birdskins,and magnificent black and white photographs. Thebounty arrived safely in Berkeley on March 23, 1932,packed in 26 waterproof cases that had traveled 20 daysoverland by mule and then by freighter to the UnitedStates. Many of the over 300 rhododendrons were rareand little known as were a number of the other 160genera also represented in these collections. The expedi-tion clearly established an important role for botanicgardens in providing new material for scientific research.

Recent ChangesRhododendron Dell thrived in the shady moist

microclimate of Strawberry Canyon while other areas ofthe Garden were developed and improved. By the 1960sthe collection numbered over 250 species, with some lost,some added since the first Andries purchase. Thirty-fiveof the 44 series describing the large genus were repre-sented by one to several species each, with hybrids andcultivars included in the display.

By the 1980s, the U.C. Botanical Garden had becomenationally known for its well-documented and largecollections of diverse plant material. Director RobertOrnduff and Curator Bruce Bartholomew established apolicy of retaining plants with clear data on origin,collector, place and date of collection and habitat. Plantswith poor or no data were relatively useless from aresearch point of view, and so were removed. As onlyabout 40% of the rhododendrons were wild-collected,many of the accessions in Rhododendron Dell were takenout, including most of the hybrids.

The species we see in today's Garden represent arefined collection of some of the most unusual speciesfrom a wide diversity of regions. R. decorum, a treespecies from China, is one of the first raised from seed byAndries and accessioned in 1932. R. protistum is one froman early Forrest expedition. R. stenaulum comes from theJoseph Rock expedition. You can see this history foryourself, by reading the accession numbers on the plantlabels, and imagining the long journeys of the seeds ofthese oldest plants, seeds that tell a story of great effortand great vision for the future.

A Busy WinterProjects: The 1990 Seed List has been sent off to 536institutions worldwide and the requests are coming in forthis year's collection of 171 offerings of unusual Califor-nia natives. Volunteers Barbara Donald, Evelyn Givant,Francine Henderson, and Liz Hunt assisted gardenersRoger Raiche and Kurt Zadnik in cleaning the seeds.Seed List specialist and volunteer Margriet Hecht is nowmailing out large bundles of seeds from the hundreds ofenvelopes arranged in neat rows in her home.

Bids for the Strawberry Creek restoration project arecoming in and the boardwalk and decks should soon beunder construction. Interpretive panels are beingplanned for the entrance to the trail and at the lower deckwith the view of the Strawberry Canyon watershed.Education Coordinator Stephanie Kaza has joined theChancellor's Strawberry Creek Advisory Committee andwill be working on an interpretive pamphlet for the creekas well as a self-guided campus tour.

Public Relations: Development Coordinator CindyRasicot hosted two press conferences at the Garden thiswinter, drawing attention to the Centennial. You can seethe Garden highlighted in the March issue of the Calalumni magazine California Monthly, with photos byRichard Anderson. The Garden was also featured in theFebruary issue of American Horticulturist focusing on theCalifornia Native area and the Garden's conservationactivities.

On February 21st, Curatorial Assistant Holly Forbeswas interviewed by representatives from a Japanesenewspaper consortium regarding the Garden's workwith the Center for Plant Conservation. Siji Hashimoto

RogerRaiche has won two more educational awards fromCalifornia Horticultural Society for his work withRudbeckia and Lobelia in the Eastern North American area.

Education Program: Rainforest Rap was a big success,thoroughly enjoyed by the 1,147 students in 41 elemen-tary and junior high classes that participated. Under-graduate instructors Chris Pires and Sabrina Sonntag didan outstanding job coordinating docents, exhibits, andstudents. Due to popular demand from schools as well asdocents, the Garden expects to offer the program againnext winter, when the rainforests will likely still be underthreat of extinction.

A new self-guided taped tour will soon be availableat the Visitor Center. The tape is a friendly, and thought-provoking introduction to the Botanical Garden for first-time as well as returning visitors.

A: Because she was leafing town.

?e, California Wildflowers: a Children's Guide to theState's Most Common Flowers. Illustrations by D. D.Dowden, text by Beverly Magley. 32 pages. Falcon Press,1989. Paper $4.95. Ages 8-12.
