    Wisconsin's Arboreta andBotanical Gardens

    Arboreta (or arboretums) and botanicalgardens play an important role in urban horticulture. More than mere gardens,their purpose is to collect, study, cultivate, displayand conserve plants for public benefit. Arboreta andbotanical gardens typically offer public educationprograms, and some house research facilities. Mostdepend heavily on volunteer staff and paidmemberships. Following is a sample of what some ofWisconsins best-known arboreta and botanicalgardens have to offer.

    The 1280-acre University of WisconsinMadisonArboretum contains the states largest woody plantcollection.

    In Milwaukee, the Forestry Division is responsible forthe design, planning, planting, and management ofstreet trees, boulevards, landscapes, greenspaces andbeautification projects with the city. The primary goalof the Forestry Division is to efficiently manage theurban landscape to provide a better quality of life forits citizens and visitors. The organization chart of theForestry Division starts with the City Forester whohas overall responsibility for the division. The city isdivided into three districts, each with a manager and55 year round employees. A Forestry ServicesManager supervises 20 professionals, including thecitys forestry inspectors, nursery supervisor,technical services coordinator and mechanicalmaintenance supervisor. Seven office staff alsosupports the Division.

    Milwaukee has its own 160-acre nursery. The nurserygrows a diverse population and was establishedoriginally to grow ash, Norway maple and elms, andlater to supply quality trees in large numbers becausethe commercial nurseries could not. Today, 17,000trees are under cultivation, supplying 98% of thecitys street trees. The city is close to full stocking,and currently replaces trees within one year ofremoval. A $950,000 greenhouse was recently built toprovide the city with flowers for their annualboulevard displays. Surplus flowers and trees are soldto the citys Summerfest grounds and othermunicipalities.

    Insect and disease control efforts are coordinated bythe Technical Services Coordinator. Employees aretrained to identify problems on trees, shrubs andflowers throughout the community, with least-riskpesticides utilized when necessary. Recent outreachefforts have been concentrated on the Gypsy mothand the Asian Long-horned Beetle.

    Maintenance on the citys boulevards includesseveral cultural practices, and due to the harshconditions also requires fertilization. The street treesare on a 3/6 pruning cycle - a three-year cycle for trees12 and under, and a six-year cycle for trees greaterthan 12. Public safety is forestrys number oneconcern, so all trees are surveyed on an annual basis.Staff is also trained to look at private trees that are apublic safety concern as well.

    Every year, the city hires 12 Forestry Interns. Theseinterns are recruited from a variety of backgrounds,and through the course of their internship learn how amunicipal urban forestry program works. Careerladders are also set up throughout the division. Priorto 1993, one group of workers performed treemaintenance activities, and another group maintainedlandscaped boulevards. However, as the divisionreorganized, Forestry employees were cross-trained inall facets of the citys greenscape. A comprehensive,hands-on, six month course includes training inirrigation installation and repair, planting andmaintenance of annuals, perennials, turf and shrubs,tree planting and removal, structural pruning by ropeand saddle and lift truck, cabling and boltingtechniques, aerial rescue and plant health care. Thebenefits include a flexible, more diverse workforce thatis also able to reduce the time to complete variousoperations.

    Open space and land use planning are hot topicsthese days. With the bulls of the Stock Marketrunning wild and housing starts hitting near all-timehighs, property is being gobbled up and changedonce again. From the lands initial state of forest orprairie, then farmland in some cases, it is now beingtransformed into strip malls, businesses, factories orhomes.

    It is imperative that environmentally sensitiveproperties, recreational sites and aestheticallypleasing areas be identified, prioritized andprotected for present and future generations. Thisprotection may be through leases, easements, re-zoning, purchase of development rights or outrightacquisition. It is difficult and expensive to re-creategreenspace after it has been developed. Planning andimplementing safeguards prior to development willensure that ample natural areas, highly productivefarmland as well as historic and cult
