"Rocky passages of the Park, which hadbeen furnished under my directionwith a natural growth of characteristicrocky hillside perennials, have beenmore than once 'cleaned up,' and sothoroughly that the leaf-mould, withwhich the crevices of the ledge hadbeen carefully filled for the sustenanceof the plants, was swept out with housebrooms . . . and all in the heart of anAppalachian glen."
-Frederick Law Olmsted. "The Spoils ofthe Park," February 1882.
wood of the native deciduous species admirably grouped by nature ... " in whatis now the Upper Park's North Woods,and in the Lower Park a large but younggrove of deciduous trees that would needfew additions.
Since the park could not rightly imitate seashore, desert, mountain, or prairie, the designers chose the overall landscape character to mimic rural scenery. Itis well documented that this artistic stylewas directly imported from England's romantic landscapes designed by HumphreyRepton and Joseph Paxton, among others.Central Park's rural scenery featured twodesign types-the pastoral landscape, consisting of broad expanses of gently rollingmeadows and placid lakes, and its directcontrast, the picturesque landscape.
To fashion Central Park's picturesqueareas, trees were left and new ones plantedto form a continuous canopy; vines weretrained to grow up tree trunks; mosses andferns were encouraged to grow in bouldercrevices; grades were changed on streamsor water courses rerouted to create cascades; imported soil was mounded up andplanted With evergreens to create the illusion of miniature mountains. Shelters orbenches constructed were usually in therustic style. Everything in the picturesquelandscape was placed to enhance the visitor's enjoyment of the lushness and detailof a wilderness. It was to be a re-creationof scenery reminiscent of the Adirondackor Appalachian Mountains-genuineAmerican landscapes. Approximately 20percent of the land that Olmsted called"heterogeneous surface"-magnificentbedrock outcrops, a series of bluffs, a steep

Americanand beaked filbert (Corylus americana andC. comuta), wild black cherry (Prunus serotina), Carolina rose (Rosa carolina), summersweet (Clethra alnifolia), sweet andswamp azaleas (Rhododendron arborescensand R. viscosum) , winterberry (Ilex laevigata) , sassafras (sassafras albidum), andcommon greenbrier (Smilax rotundifolia)were listed as abundant, common, or(very) numerous. The part of the landscape not disturbed by cutting, grazing, ortrampling was regenerating. Olmstedwrote in 1857 about" ... a fine young

Contrary to written descriptions byClarence Cook and others that give theimpression that the land "as mostly barren, a survey of existing plants on theground for Central Park conducted in August and September of 1857 by CharlesRawolle and Ignatz Pilat records morethan 280 species, many of them native.Rawolle and Pilat estimated that therewere 12,000 American hornbeam (Carpinus americana); 9,000 red maple (Acerrubrum); 8,000 specimens of nine Quercusspecies; 6,000 sweetgum (Liquidambarstyraciflua); 3,000 black locust (Robinia
Clnlty (Parks & Recreation Natural Resources Group, 1993) Although only fragments of the pre-colonial forest survive,Marc Matsil, director of the Natural Resources Group, and his staff have doneenough investigation to confirm that theplant community matrix was and continues to be unique on the Eastern Seaboardbecause of its location at the juncture oftwo hardiness zone limits. For instance,Staten Island still has evidence of sugarmaple and beech forests (a northern hardiness zone plant community at its southern limit) mingled with hackberry andsweet bay magnolia (a southern hardinesszone plant community at its northernlimits).
Although plant records are not explicit until the 1800s, we do know thatmost of the original forest on ManhattanIsland was cut by the Dutch and Englishsettlers. The forest was further denuded bythe British military who occupied the island for seven years (1776 to 1783) duringthe Revolutionary War. These actions directly affected Central Park, since therewas a line of fortifications across its northern limits along with three permanent encampments. From the city's tax and condemnation records we also know that theland on which Central Park was built waschanging rapidly during the mid-1850s asNew York City expanded northward onManhattan Island. As many as 5,000 people lived within Central Park's originalboundaries, 57th to 106th streets, at thattime. Land use varied from farms, pasturage, piggeries, and dwellings with subsistence gardens to churches and cemeteries,taverns, bone-boiling factories, rubbishheaps, quarries, and abandoned military
The Genesis of CentralPark's WoodlandsTo create New York City's Central Park,341 ha (843 acres) of prime real estate setaside for public use, many thousands ofcartloads of top soil were imported fromNew Jersey and Long Island, hundreds ofpounds of dynamite were used to blast theManhattan schist bedrock for the sunkentransverse roads, and miles of clay pipewere laid to thoroughly drain the landscape. Between 1857 and 1873 Olmstedand Vaux oversaw the creation of an idyllic public landscape out of what at thetime was considered a relatively nondescript parcel of land at the city's urbanfringe.

Few restoration projects have assumeda civic dimension as broad as that of
the recent woodlands revival in NewYork's Central Park. From removing political roadblocks to surviving public scrutiny to handling an eager but diverse corpsof volunteers, park planners faced tremendous challenges that required innovativeresponses.
Rather than a restoration to a precontact landscape, the Central Parkwoodlands project sought to renew themagnificent urban plan of Frederick LawOlmsted and Calvert Vaux, who designedthe park in the mid-1800s. Their originalintent-to create rural tranquillity amongthe chaos of the city-guided each phaseof the restoration.

For the next several years the park wasexamined from top to bottom by hydrologists, soil scientists, foresters, sociologists,and landscape architects. Each park-widecomponent system-geology, topography,utilities, soils, hydrology, vegetation andwildlife, maintenance, and security-wasinventoried and analyzed. Investigationsof park annual reports, maps, and photographs helped piece together a complexand fascinating history of the park and itscomponent systems. I was part of the fourperson planning team responsible formanaging the process and compiling andinterpreting all data gathered by consultants and Central Park staff. In our analysisand subsequent plan formulation, we decided to divide the park into three distinctlandscape types based on physical attributes and management needs. Of thethree-meadow, parkland, and woodland-woodlands were the most complexand, at the time, the least understood.
ing a small committee to participate in thewildlife inventory and analysis, it wasbusiness as usual.
The Management andRestoration Plan
the begirming of an overall reduction inthe tree canopy and subsequent loss ofhabitat for birds. At public hearings heldby the Landmarks Preservation Commission and community boards many userssang praises for the wild cherry (Prunusserotina), the major species removed, as anexcellent food source for migratory birdsthat should be kept at its present densityand number. It was very clear at the endof the public airing that the environmental community had lost any shred of trustin agency decision-making and preferredthat nothing be done at all in the woodlands.
The incident captured the attentionof the news media nationwide. For thoseof us who were about to embark on aneven more difficult planning effort for theentire park, the episode was particularlyenlightening. For me, as I think it was for ,all the staff, the lessons learned from thepublic upheaval were ingested but not entirely assimilated. I had witnessed publicopposition that effectively foreclosed thechance to rebuild a degraded area of thepark. At the time my planning colleaguesand I did not propose major public involvement in the plarming process wewere just beginning and except for creat-
erations and capital budget for the park.In the past decade, the conservancy andits board of trustees has played an everincreasing role in managing, restoring andmaintaining the park, and providing services and educational opportunities for itsvisitors.
The establishment of the conservancy put the administrator, a city-appointed official and president of the conservancy, in a position to craft uniqueprocesses to manage and restore the park.For instance, in the absence of availablecity monies for planning, the conservancyfunded the initial blueprint for the park'srestoration in the early 1980s. In othercases, by funding design, the conservancycould leverage projects into the Parks department's budget when other projectsfailed to make the commitment plandeadline. Subsequently, it has providedthe support needed to initiate and sustainthe woodlands program.
Immediately before the planning effort began in earnest, an incident occurredthat would directly affect the woodlandrestoration process. A 1979 master plandrafted for the Ramble-a 36-acre woodland and premier birding area in the center of the park---emphasized restoringOlmsted's design intent (that is, it was nota restoration to the pre-contact landscape). To reclaim a vista established byOlmsted, two dozen trees were removed.The decision was made without significant public input, and heated dJbate followed.
The majority of protesters testifiedthat the removal of trees was an isolateddecision that did not take into accountpost-removal issues such as plant replacement or area management. Although agroup of naturalists and users had authored the wildlife chapter of the reportand the proposal had been presented atseveral public forums, there had been noformal review and revision process, andthus no consensus for the recommendations. There was dismay at the lack ofpublic involvement in the removal decision.
Change in general in a city where astreetscape can change overnight is considered suspect. It is not unusual to receivecomplaint letters about the removal of afavored overhanging branch or a bench.This time the removal of trees was seen as
water drainage system, floods, eutrophicwater bodies, and buildings covered withgraffiti. The park was literally "goingdown the drain."
The woodlands were the first landscapes that park management abandoned.Abandonment is of course a managementdecision in itself; in this case it was madebecause there was no other choice. By themid-'70s, the decimated maintenanceforce could hardly keep up with properlawn care and daily garbage collection.
Although no year-by-year record of management decisions isavailable to document what actually happened when thewoodlands were abandoned, acomparison of the 1934 fieldsurvey and the 1982 groundplane survey tells one part ofthe tale. Because mowing wasdiscontinued, many smallwoodland glades extant in 1934had disappeared by 1982. Opportunistic species such as wildcherry, sycamore maple (Acerpseudoplatanus), Norway maple(A. platanoides) , and Japaneseknotweed (Reynoutria japonica)had replaced "lawn."
The year 1979 broughtnew life to Parks and Recreation. New York City's fiscal crisis ended, a new administrationwas voted into office, and a newParks commissioner, GordonDavis, set about making sweeping changes in his moribunddepartment. In order to re-establish authority and responsibility at the lowest possiblelevel, the commissioner initiated a decentralization of thedepartment by re-institutingfive borough-level park commissioner positions and creat-ing the position of administrator for major regional parks of
the system. Elizabeth Barlow Rogers wasappointed as the Central Park administrator.
One of Rogers' most significant initiatives was to create a non-profit corporation, the Central Park Conservancy,whose mission in part has been to raiseprivate funds to supplement the city's op-
fitness and an appetite for large events;maintenance was decreasing. Long-termplanning and management were nonexistent. This deadly combination was soonmanifested in the park's physical condition-loss of ground cover, diseased trees,severe soil erosion and compaction, thebreakdown of the underground storm-
Central Park has gone through many cycles of deterioration, public concern andoutcry, and subsequent renewal. The mostsevere decline occurred during the 1960sand '70s, when New York City budgetcuts coincided with the rediscovery of thepark as a vital recreational and culturalcomponent of public life. Use was increasing, spurred by a new concern for physical

stream valley-was treated in this manner. Today 52 ha (130 acres) of the original picturesque landscape (falling intothree areas-the North Woods, the Ramble, and the Hallett Nature Sanctuary) aredesignated park woodlands.
In constructing the park Olmsted andVaux did not attempt to restore the original deciduous forest or the shallow emergent marsh meadows (called "muscoota"by the native Americans) that existed before the advent of the first European settlers in the early 1600s. Olmsted was creating an idealnaturalistic landscape-naturalin its visual composition, notits species composition. He andhis horticulturists orderedthousands of plants from nurseries in England, Scotland, andFrance that offered a greater variety and number than theirAmerican counterparts, whichwere not yet ready to supply thehundreds of thousands of plantsactually installed in CentralPark. Even if an all-native plantpalette had been available, I seriously doubt they would haveused them exclusively. Afterall, development of the parktook place at the height of theage of the great plant explorations, when anything exotic,looking would have been seizedand popped in the ground. Allowing for the scant information on plant communitiesavailable to the builders andfirst managers of the park, theywere not making the wrong decisions.
As always, the passage oftime is the one limiting andregulating factor that occurs inall living systems no matterhow raw their beginnings. Tothe living communities pres-ent, the park's original construction musthave been as cataclysmic as a major earthquake (although I still marvel how muchof the original physiography was left intact.) Then came more than a century ofthe land's use as a park. As in many similarnaturalistic parks around the country, oursdid not fare well.

the restoration of the woodlands our intent is not to restore the Olmstedian landscape species for species and placement forplacement as it was in 1873. We are usingas our ideal Olmsted's original ideal-theforests of the Adirondack and Appalachian mountains-positioned by our present conceptual knowledge of the ecologyof the landscape, its structure and function. How different would a historic photograph of the Ravine look as comparedto a photograph of a landscape restored to
the structure and function of the EasternSeaboard forest? Not much.
This justification does not mean thatin every case ecological and historic restoration are the same. It also does notmean that there are no conflicts betweena historic restoration and an ecologicalrestoration. For instance Olmsted redesigned an original stream flowing throughthe Ravine into a series of pools and cascades. Over time the pools have filledwith silt from the watershed. Today thecentral portion has reverted to a marshystream course. The structure of the landscape is interesting, but not as rich as itscounterpart would be in a natural situatiCin. How should it be restored? Shouldthe current hydrology of the system determine its form and function? Should it bedesigned as an efficient bio-filter? Shouldwe dredge to re-create the Olmstedian wa-
...plants already proved successful-such aswoodland aster (Asterdivaricatus) and Virginia polygonum (pQlygonum virginiana)would be used. Only later when the woodswere healthier would a ground layer ofmore fragile plants be introduced. In allcases natural processes would be encouraged, but at the outset of woodland management and restoration it was not knownwhat the prospects were for recovery ofthese heavily impacted sites.
As Leslie and I began to envisionwhat the components of a woodland restoration process would be, I was thinkingabout my other sacred trust-that of restoring the intent of the Olmstedian landscape. "Intent" is not meant to have anarcane meaning. Simply put, Central Parkis a scenic landmark that was createdsolely for the health and enjoyment ofpeople-past, present, and future. In orderto accommodate present and future use,the park must be changed and adaptedbut, in all cases, using the general designprinciples manifest in the original plan.For instance, an original pathway mayhave to be relocated to accommodate anew destination. The actual placementtakes a secondary role to nestling the pathinto the landscape, providing a pleasingcurve and contour for the path and positioning it at the edge, not the middle, ofa pastoral landscape type. With regard to
tions and site visits, Leslie suggested starting the project with a key informant survey that concentrated on problems andconcerns. The premise: by beginning dialogue and trust building on an issue, itwill be less difficult to gain consensus.
During the summer of 1988 Lesliemet with groups and individuals representing the environmental community,adjacent park neighborhoods, and a widevariety of woodland users in addition toParks department and Central Park personnel. Informal conversations were conducted with woodland users as she inspected each site. The result was a' draftdocument, "Landscape Management &Restoration Program for the Woodlandsof Central Park, Phase One Report: Consensus of the Interviews, Key Issues & Initial Program Recommendations." Publicinvolvement continued. The draft was released to the original participants with arequest for written comments from whichthe final report was compiled and thendistributed to a larger public audience inDecember of 1989. Participant commentsreflected a continuing skepticism that history and environmental imperatives couldever coalesce; however, all were pleasedwith the process up to that point.
Four major problems of the woodlands were identified: 1) off-path use ofbicycles and vehicles, 2) off-path trampling, 3) breakdown of the storm-waterdrainage system, and 4) the spread of exotic invasive plant species, particularlyNorway maple, sycamore maple, and Japanese knotweed. The report admitted thatthere was little known about the management and restoration of urban woodlandsand recommended that much of the restoration be incorporated into the day-today management of the landscapes over amuch longer period of time (decades tocenturies instead of months to years). Theapproach would not only reduce stresseson the woodland ecosystem but also reduce the chance of large-scale missteps byallowing time to do the necessary inventory, research, and monitoring.
Firm boundaries were established foreach woodland area and buffer zones delineated. Within these boundaries, Leslierecommended only native plants be used.At the beginning of the process when thewoodlands were being "stabilized," native
we would have to invent a completely different process for planning and fundingthe woodland restoration. When I madethe case, the conservancy, understandingthe seriousness of the problem, includedwoodland planning as a part of their capital fundraising effort.
After six years of constructing standard landscape restoration projects in thepark, it was evident that this process couldnot be used as a model for the woodlands.Construction documents are deceptive.On a layout plan, a dashed line for a newstorm-water drain looks quite innocuous.It really means large machinery lumberingacross the landscape compacting soil anddeep excavation obliterating soil structure. True, mitigations could be devised,but the woods would still be affected. Capital construction procedures were evenmore ~avalierwhen addressing new plantings. This was the stuff of nightmares afterwitnessing the mayhem brought on by removal of two dozen woodland trees.
As the person responsible for park design and planning at the time, I made several decisions that began to shape our process. The first was to ask Maintenance andOperations to assume direct reporting responsibility for woodland restoration.Planning, design, and construction departments would have an advisory relationship. The second was to commit topublic involvement at the start of the project no matter how messy the process became. Our generic approach to involvingthe public up to this time was straightforward but did not engender public ownership of the decisions: first create the project plan, then request public input. Thethird was to go outside the Parks department to find an unbiased professional whohad the ability to balance both environ~
mental and historic imperatives. Thus began the partnership with Leslie Sauer ofAndropogon Associates that continuestoday.
I remember asking Leslie as wewalked through the Ravine what we aspark managers should do when a treeany tree-fell in the woodlands. I do notrecall her exact reply, but it had to do withcreating a woodlands management program to be a paradigm of process and balance and let nature do as much of thework as possible. After initial conversa-
celerated as the conservancy began toraise significant private dollars. There waslittle momentum for woodland projectsthey were too controversial. But in 1986,as the conservancy was preparing to gopublic with a five-year, $50 million capitalcampaign, an updated capital project priority list for the fund-raising effort wasneeded. While I was preparing a .mapshowing projects completed and in theplanning, design, or construction stages,one glaring omission resurfaced. The parkwoodlands were nowhere on any schedule.
Planning for and undertaking restoration of the woodlands could no longerbe ignored. Our mission was to restore theentire park-not just the easy parts. Manyof the particular problems of three out ofthe five major park watersheds were thedirect result of deteriorating conditions ina woodland landscape. However, I knew
Our general woodland goals and recommendations that were a part of thepublished plan, such as leaving somestanding and fallen deadwood, eliminating erosion caused by the breakdown ofthe storm-water drainage system and offpath trampling, and controlling one nonnative species (Japanese knotweed), dealtalmost exclusively with what should bedone, not how to do it. Woodland landscape restorations were budgeted andscheduled like any other capital construction project. Looking back, it seems to methat we were just beginning to view thepark and in particular the newly labeledwoodlands as complicated natural systemsin addition to recognizing their significance as an important visual componentof the Olmstedian plan.
In the mid-1980s the restoration ofthe meadows, parkland, and buildings ac-

Leslie was absolutely on target when shetold me to get our toughest critics on theadvisory board. It would have been easyto only recruit park friends and, believeme, I was tempted. The lesson learned isthat you always meet your critics somewhere down the road. Better it be in aforum designed for working togetherrather than fighting against each other. Itwas not as if the board was to be composedsolely of users- life-long birders, membersof the Audubon Society or Sierra Club,community board members, or writers onthe environmental scene. In fact, close tohalf the board has always.been parks department staff.
We created the advisory board as aworking committee meeting 12 or moretimes a year. Many of the same participants in the initial survey were asked tojoin the board. I asked Leslie to continueto consult with us as the chair and facilitator of the board and as an advisor to thestaff. This has been a very different wayof using a consultant. In effect the consultant is training the staff to make decisions and do the work. During the firstyear the advisory board established protocol, reaffirmed woodlands problems anddecided what issues to tackle immediately.These first decisions were critical to thesuccess of the board. Field implementation would only proceed if board consensus could be reached. A meeting summarywould be distributed and become part ofthe continually developing management"plan."
After site visits the board chose theNorth Woods area to concentrate its ef-

care for the woodlands, and 3) understanding and appreciating the importanceof Central Park's woodlands and forestsworldwide.
First it was important to establish anidentity for the woodlands as places witha unique set of characteristics, problems,and opportunities. The first step Leslieand I took was to coin the name NorthWoods for the collection of historicallynamed landscapes-the Great Hill, theRavine, and the area surrounding BlockHouse No. 1.
People as Part of the ProcessAlthough it took time for the park managers involved to become comfortablewith the concept of public involvement,the fundamental idea of "managing toward ..." rather than "constructingto ..." was accepted immediately. We began using medical jargon in reference tothe woodlands. Methods of erosion control became "trauma blankets." Prioritizing the woodlands was compared to a patient in a hospital choosing to undergothe coronary by-pass before having thefacelift. The vocabulary was certainlyappropriate: we had a patient on the critical list.
Public involvement has grown organically out of the key informant survey recommendations. It has taken three years toput into place a full range of programs thatengage the public-at-large, and the programs continue to evolve. This involvement now encompasses three roles: 1) decision-m~king, 2) helping to restore and

ter body? These questions have yet to beanswered.
Just as important, Central Park'swoodlands offer a pivotal laboratory forboth the public and restoration professionals. It is "ground zero"; if a sustainablenative forest can be established here, itcan happen anywhere. Central Park is alandscape fragment. I like to describe it tothe public as an island (the green rectangle) within an island (Manhattan Island)within an island (the metropolitan area).To the restoration community, it mayseem too small to have meaning withinthe larger restoration picture. But to theurban population whose only forest experience is in the park, or to the migratorybirds searching for a place in the sea ofasphalt and glass to rest and refuel, it isirreplaceable. It deserves the most carefulrestoration we can offer. In Central Park'swoodland, people are a part of the landscape ecology: they provide its structureand function by definition of the originalmission of the park.

"The management of the ground between the skating pond and Vista Rock'(nowknown as the Ramble) appears to be indicated by its fonn and the character of itspresent growth. It is well sheltered, and large masses of rock occur at intervals. Thesoil is moist, and altogether remarkably well adapted to what is called in Europe anAmerican garden, that is, a ground for the special cultivation of hardy plants of thenatural order Ericacaei, consisting of rhododendrons, andromedas, azaleas, kalmias,rhodoras &c. The present growth, consisting of sweetgum, spice-bush, tulip-tree,sassafras, red-maple, black-oak, azalea, andromeda &c., is exceedingly intricate andinteresting. The ground is at present too much encumbered with stone, and withvarious indifferent plants. By clearing these away, and carefully leaving what isvaluable; by making suitable paths, planting abundantly as above suggested, andintroducing fastigiate shrubs, and evergreens occasionally, to prevent a monotonyof hushes, the place may be made very channing."

forts. It was less impacted and less used,and thus a less controversial area to beginwork. The board w~nted more information such as the relative health of theNorth Woods, especially regarding the extent of the spread of non-native' trees.With board approval, four categories ofrelative health were defined and recorded."Stable" areas were defined as predominantly native communities with minimalexotic invasion. "Declining-earlystages" would contain predominantly native communities, with evidence of earlyinvasion, primarily seedling and saplingsize plants. Invasive non-natives were reproducing at a greater rate than natives."Declining-later stages" would includethose landscapes with native communitiesstill present but with reproduction distinctly curtailed and invasive non-nativeswell established and spreading rapidly. A"degraded" area would exhibit nonnatives well entrenched with minimal orno reproduction of native species. Nativeplants might still persist as besiegedpatches of ground cover or lone canopytrees.
This inventory was not a scientificcount: it was a "reading of the landscape"and the first assignment of the newly hiredwoodlands manager under Leslie Sauer'stutelage. Field implementation guidelinesfor each mapping unit were then established. Stable areas would receive monitoring and trash removal. If necessarymanual removal of new non-native seed-
lings would occur twice a year. Degradedareas would also receive trash removal butin effect be contained by management ofdeclining areas on their perimeter. Itwould be the declining areas that wouldneed more management effort. The advisory board instructed the WoodlandsManager to begin removing non-nativeinvasive seedlings and saplings up to 4inches dbh in order of early-declining tolater-declining areas. Removals wouldonly occur when enough native groundcover was present to hold the top soil andwhen a sapling was not a part of the overstory canopy. All removals would bemanual; no soil would be grubbed to effectcomplete root removal; there would be noremoval if an excessive amount of soilwould be exposed. The goal was toachieve a gradual expansion of the extentof stable landscapes. It was also agreedthat this approach would have the highestcost-benefit ratio as less effort would berequired for removal and the existingplant communities would hopefully closeranks without additional planting.
In some cases it has taken severalyears to educate ourselves to the fact thatthere is no information out there onwhich to base decisions. Many boardmeetings are spent discussing so'me aspectof our program, such as the advisability ofusing herbicides. Leslie is the personmainly responsible for finding and distributing relevant literature and leading thediscussions. I always meet with her before
board meetings to discuss the agenda issues and visit the woodland sites underdiscussion. The woodlands manager anddirector of horticulture have a standinginvitation to attend these meetings.
The board has moved on to manymore issues and projects, such as establishing monitoring plots to test herbicide versus manual removal of Japanese knotweed. This past year the board developedan implementation and monitoring planfor the removal of seminal non-native invasives. For a board to assume this sort ofmission requires a talented facilitator andcommitted members. It also needs expertise. We have been fortunate to have as ·members the assistant director of thepark's Natural Resources Group, DeborahLev, and a researcher for the Institute ofEcosystem Studies, Dr. Richard Pouyat.They have helped craft monitoring andresearch studies-the most recent ofwhich will begin to document the presence or absence of ectomycorrhizae anddo comparative studies in non-urbanforests.
Caring for the Woodlands:Volunteers and DonorsDennis Burton, the new woodlands manager and "insider" who had worked on theCentral Park Conservancy's tree crew andvolunteer program, began by recruitingvolunteers to implement the work program. Using volunteers had been a recommendation of the Phase I report andnevertheless there were no funds availableto hire a crew. Letters went out to environmental organizations. In the spring of1991 Central Park celebrated Earth Daywith volunteer recruitment and woodlandtours. Participants of Central Park's volunteer clearinghouse, Learning and Involvement for Volunteers in the Environment (L.I.V.E.), also transferred into thewoodland program.
Woodlands volunteers were asked todo more than clean, paint, sweep, andrake: they took on tasks normally performed by the park's landscape crews.Necessary specialized training was provided by the woodlands manager. A poolof 50 individuals became adept at identifying and removing invasive non-natives,collecting native seed for planting in areas
where soil stabilization was necessary,constructing trauma blankets, plantingnative materials and of course picking uplitter. Invasive seedling and sapling removal was accelerated by the discovery ofthe Weed Wrench, a leverage tool thatcan slip root systems out of the groundwithout disturbance.
Several other volunteer opportunitiescame our way and Dennis was quick toplug them into his work schedule. Onecall was from a teacher at the ManhattanSchool for Career Development, a publicschool for 16- to 21-year-olds with learning disabilities, who was interested in establishing a parks-related job-training program. The program has completed itssecond successful year, and several partic-
ipants have been hired to work in thepark. Another call came from the advisorof the Ecology Club at the American Museum of Natural History about how to useCentral Park as their backyard laboratory.Dennis set them to work monitoringwoodland plots.
On another front the Central ParkConservancy, with the Phase I report inhand, began to prospect for donors. Manyof the foundations with an environmentalmission were looking for projects of national significance that would includepublic involvement and education. Withour program just beginning it was a difficult road, particularly for the first grant. Itcame from the Andy Warhol Foundationfor the Visual Arts, which believed in our
budding program and committed to a twoyear grant. Later support has come fromthe Norcross Wildlife Foundation and theLila Wallace-Readers Digest Foundation.In addition to this support came the conservancy fund-raising effort known as theCampaign for the Upper Park (CUP). Established to implement 50 recommendations from a park use and security taskforce report released after a woman joggerwas beaten and raped by neighborhoodyouth in the Ravine in 1989, CUP supplied funds to repave deteriorated pathways, reset steps, or create roundaboutsand rebuild crumbling pedestrian bridgesin the North Woods so that small maintenance and security vehicles could reachthe woodland interior. As the circulationsystem and its storm-water drainage system is upgraded, woodland volunteers follow to plant and seed the landscape edges.
Funding also came from the city inthe form of the restoration of two arches,Glenspan and Huddles.tone, which areportals into the woodland stream valleycalled the Ravine. Although severalplanting plans had been completed, theywere done before the inception of thewoodlands program. This was a unique opportunity to guide a small capital projectusing woodlands principles and to improve two degraded areas on the relativehealth map. Starting from scratch, weworked with staff landscape architects andthe board to complete a detailed inventory and analysis of each site landscape, ageneric landscape type map, and a lise ofnative plant materials to go with eachtype. The contractor for the project wasthe Central Park Conservancy, whichprovided the masonry crews and supervision to restore the bridges. Work requiringgeneral construction skills such as pavingwas subcontracted but supervised by conservancy personnel. The woodlands manager was the site supervisor for the landscape restoration, working in tandem withthe general construction supervisor andproject landscape architect. Through thecontract he hired two site workers to implement the restoration plan. After thecontract ended the workers were hired bythe conservancy to be the woodlandsmanagement crew. Other Andropogonpartners were brought in to help the crewconstruct adventure trails-a new form of

pathway for the woods-and to site plantmateriaL Between the small capital projects and three years of consistent management supported by the volunteers, bythe spring of 1993 we were ready to invitethe public back to the Ravine.
Urban Forest Appreciationand Education: PublicPrograms and OutreachThe 1991 Earth Day event was our firstattempt to reach out to the park user. Itwas the first time in recent history thatpark managers and staff had met andtalked to the park public on a one-to-onebasis. Earth Day in 1993 added a new selfguided walking tour brochure of the "Ravine in the North Woods" (Quebecordonated printing costs as their Earth Daycontribution). Complimentary copieswere distributed at major park entrancesand to tour participants. The woodlandscrew and summer youth interns continuedto hand out free copies of the brochurelast summer. This past year a new eventwas added to the woodland event schedule-the first Annual National TrailsDay---eo-sponsored by Eastern MountainSports and the Conservancy. Althoughthe national message of the day was tocare for our forest and wilderness trails,Central Park's message was enlarged to include the consequences of hiking or biking off-traiL The public was invited to joina volunteer work crew to repair an offpath desire line. Through their suppliers,EMS also donated funds to the woodlandsprogram and is excited about continuingto work with the conservancy in thewoods.
On a day-to-day basis our new ambassadors for the woodlands are the members of the woodland crew. Providing amuch-needed presence, they also remind
visitors about rules and pass on information such as bird sightings and plantnames. Last summer was the second summer the Conservancy's Summer Youth Intern Program, employing high schoolyouth from the city, has sponsored awoodlands crew. This year the programemphasized work and study. The crew participated in a wide variety of activitiesfrom site monitoring to providing information to the park visitor.
Signs are another way to get thewoodland message out to the public. Thispast summer a new environmental signsystem was tested in and around theNorth Woods. The sign system will helpvisitors navigate more easily through thepark and will also for the first time alertthem to general park rules and rules forspecial landscapes such as the woodlands.Ever since prot~ctive fences have been installed, we have been posting temporaryinformational signage on them that informs the visitor about the woodlandmanagement and restoration program.
This past fall a new visitor center emphasizing environmental issues opened tothe public. Educators with input fromDennis, Leslie, and me planned and arenow offering educational programs forschools and the general public that usethe park's woodlands and water bodies asa resource. The center will feature an environmental timeline and provide the Ravine walking tour brochure and a newpublic information quarterly newsletter,WOODS WATCH, to the public.
The woodlands program has for mebeen an achievement not only because ofthe results but because it has included thecooperation of virtually every departmentin the Central Park organization. Eachsmall success is the result of this cooperation. Although there are many ways tocraft a process that includes public pa~ticipation at every level, I am continually
amazed at how well our particular processworks. I am even more delighted when Itake a Saturday hike through the NorthWoods and encounter birders, families,and teenage couples who would havenever used this part of the park five yearsago. Much more work is necessary on allfronts and some of our potentially controversial management and restoration decisions are still ahead of us. It is just thebeginning.
