Indiana University –Bloomington A HistoricWalkingTour

Introduction ThelatePaulWeatherwax,anIUalumnus,facultymember,andeminentbotanist,wrotein1974:

Within the memory of alumni and former students, Indiana University has grown to be one of the great educational, cultural, and scientific centers of the world. A unique facet of its many-sided character is its campus with much of its original association of plant and animal life. There are few places in the world where great laboratories, classrooms, libraries, auditoriums, and other such centers of intellectual and artistic creativity are located in an environment which retains its primeval character—few places where one may so quickly and so completely cast off the tensions and anxieties of this complex modern world in quiet meditation. The tradition of a green campus and natural areas continues with the support of the IU Administration. We are fortunate to have easy access to the luxuriant forests of southern Indiana that have been specifically dedicated for teaching and research.

This brochure was inspired by Weatherwaxand his publication, The Woodland Campus, whichhighlighted the natural beauty of the forests ofIndiana University–Bloomington. Weatherwax, astudentandfacultymemberatIUfrom1914to1959,wroteandpublishedthefirstversionofThe Woodland Campusin1966,withsubsequentrevisedpublicationsfollowing. With generous support from the IndianaDepartment of Natural Resources Community andUrban Forestry Program, this brochure was writtenand published in hopes that a new generationof students, faculty, staff, and visitors to IndianaUniversity–Bloomington will be inspired by thewoodlandcampus.

History of the Woodland CampusI want to say at the outset that I don’t think I have ever been at a more beautiful university commencement than this. I shall always keep in mind this scene here in the open by the University buildings, a university which, in what we are apt to think of as a new nation, is approaching its centenary, here under these great trees, these maples and beeches, that have survived over from the primeval forest . . . it is a sight I shall never forget; it will always be with me. . . .

~ Former U.S. President Theodore Roosevelt, 1918 IU commencement speech

RooseveltwasrighttonotethenaturalbeautyofIndianaUniversity’scampus,muchastheuniversity’sownBoardofTrusteeshadin1884whenmakingasitereporttothegovernorofIndianaastheuniversitypreparedtomovefromitsoriginallocationinsouthernBloomington.“Asiteunsurpassedinthestateforitsnaturalbeautyandfitnessforthepurpose,”theywroteofthose20acresthatwerethenattheeasternedgeofthecity. Knownas“Dunn’sWoods,”thisoriginalportraitofsouthernIndianawoodlandremainsintacttothisdayastheuniversityhascontinuedtoexpandfromitsoriginalquadrangleofbuildingsaroundthosewoodsto encompass nearly 2,000 acres. And as Dunn’sWoods was the heart of the original campus, theuniversity’s commitment to preserving a woodlandcharacterwithabundantgreenspacehasbeenattheheartofitsongoingexpansion. Early credit for the university’s predispositiontoward protecting the natural beauty of thecampusgoes toDavidMottier, headof theBotanyDepartment at IU from 1898 to 1937. Charged in1913 with initially developing an overarching “planforthewalksanddrives”oncampus,Mottierhasbeenrecognizedasoneofthefirsttoadvocatepreservationofthewoodlandcampusaesthetic. By1929theworld-renownedOlmstedBrothersof Brookline, New York, had been hired to designa plan for the campus, and in their 1939 report tocampus administrators, the designers of New YorkCity’sCentralParkstronglyadvocatedforretentionofDunn’sWoodsasapark. Philosophically underscored by IU’s iconicpresidentHermanBWells throughbothhiswords

and his actions over a career that spanned eightdecades,IU’swoodlandcampus—citedrepeatedlyasoneofthefivemostbeautifulinthenation—remainedcentral to the university’s commitment to learning,research,andservice.

Current Projects and the State of the Woodland Campus With such a rich history of tree care andpreservation, Indiana University–Bloomingtoncontinues to manage the woodland campus todaywiththespiritoftraditioninstilledbyleadersofthepast, but with new, innovative tools and techniquesthathavebuiltuponitsreputationofnatural,woodedbeauty. Through collaboration among faculty,students, and staff, recenteffortshavebolstered theuniversity’s management of the woodland campus,includinga treemanagement inventoryprogram,aswellasdesignationasa“TreeCampusUSA.”

Campus Tree Inventory Managing the woodland campus requires aninventory of it. Prior to 2007, IU–Bloomingtonmaintainedonlyaninventoryoftreesthathadbeendonated to campus; a complete inventory of thewoodlandcampusdidnotexist.Throughcollaborationbetween the Task Force on Sustainability and theLandscape Architect’s Office, an ongoing Campus Tree Inventory Internship was undertaken in 2007with thehopeof establishing a constant system formonitoringthewoodlandcampusconditions. Inventoryprotocolcallsforinformationcollectedonindividuallyplantedtreesincludingatree’sspecies,diameteratbreastheight(orDBH,whichisaproxyfortreeage),height,andcondition.Inaddition,thelocationofeachindividualtreehasbeenrecordedusingGlobal Positioning System (GPS) instrumentationthat allows for accurate mapping. A database isusedtomanageinventorydata,fromwhichonecansummarize the tree demographics of the woodlandcampus. Even more exciting has been the use ofU.S. Forest Service software that has allowed treeinventoryinternstocalculatetrees’ecosystemservicevalues. The following section details the currentlyinventoried tree demographics and economic valueaddedbytrees’ecosystemservicesoncampus.

Campus Tree Demographics and Ecosystem Services Ecosystem services are the all-too-oftenunrecognized benefits that trees provide, includingair quality improvement, carbon storage andsequestration,energysavingsfromshadingbuildings,

Ingeneral,the larger the tree, the larger its canopy, the moreecosystemservicesitprovides. The most populous species in the currentlyinventoriedportionofcampusincludeSugarMaple,Red Maple, Black Cherry, Northern Red Oak,Silver Maple, and Flowering Dogwood. The treesin the current inventory were found to be in goodcondition and distributed well across different ageclasses, promising a sustainable tree population forgenerationstocome.Canopycover,ortheareacoveredby tree canopy projected onto the ground’s surface,wasestimatedtobe47percentwithintheIUcampusboundary (including the heavily wooded Researchand Teaching Preserve), 7 percent higher than therecommended40percentcanopycoverforcitieseastof the Mississippi River.The calculated net annualdollarvalueofthebenefitsprovidedbythecurrentlyinventoried trees is estimated at over $400,000! Ifthisinformationisextrapolatedtoestimatethevalueof all treesoncampus, it is safe to say that IUandtheCityofBloomingtongarnerat least$1,000,000in ecosystem services each year from the woodlandcampus.

The Tree Campus USA program wasmodeledaftertheArborDayFoundation’sTreeCityUSAprogram,ofwhichBloomington,Indiana, isadesigneeandtheoldest“TreeCity”inthestate.TreeCampuses are recognized for effective managementof campus trees, urban forestry collaboration withthecommunitybeyondcampus,andengagementofstudentsinurbanforestry.Specifically,aTreeCampusUSAis required tohave (1)acampus treeadvisorycommittee,(2)acampustreecareplan,(3)acampustreeprogramwithdedicatedannualexpenditures,(4)an Arbor Day observance, and (5) service learningopportunities related to urban forest managementfor its students.

Future of the Woodland CampusI hope that our alumni will always insist on retention of our precious islands of green and serenity—our most important physical asset, transcending even classrooms, libraries, and laboratories in their ability to inspire students to dream long dreams of future usefulness and achievement—dreams that are an important and essential part of undergraduate college experience.

~ Herman Wells, in 1962, his final year as president, in an address to alumni on the state of the university

Where will Indiana University–Bloomington’swoodland campus be in 25, 50, or 100 years? Toanswer thisquestion,onemustconsider thedrivingforces that influence the woodland.
