Center for Urban Horticulture / Washington Park Arboretum / University of Washington CENTER NEWS Thoughts , Smites , and Spring An old saying goes “Be careful of your thoughts, they might blossom into words. ” I couldn’t help but think of this as I was review- ing all the events which needed to go into this edition of the newsletter. Indeed, lots of gar- dening thoughts are springing into action in shows, lectures, tours, plant sales, and other Special events. As I write this, already the Cyclamen are poking their heads skyward, meaning the full flush of spring color isn’t far behind. To select another saying, I’ll conclude with “The world looks brighter from behind a smile. ” And to me, spring means smiles. John A. Wott Associate Director and Professor of Urban Horticulture Coordinator Chosen We are happy to announce that Mr. David Stockdale, presently from Austin, Texas, has been chosen as the new Coordinator of Con- tinuing Education, starting March 1st.

NEW IN THE WASHINGTON PARK ARBORETUM A comprehensive plant records project has been under way in the Arboretum for nearly two years, and it is now coming to fruition. 1. Computerization of All Plant Records Jan Pirzio-Biroli and three volunteers — Eileen MacDonald, Pat Killingsworth, and Karen Panek — have computerized the acces- sion records of all the plants in the Ar- boretum. There is now a permanent, accessi- ble “electronic” record of each plant, its location, its source and date of planting, and the verification of its identification. In the fu- ture, the • computer program has the ca- pability of storing and (coordinating) many other types of information useful for collec- tion management. 2. Mapping and Inventor y Since last year, a group of mappers has been working throughout the Arboretum. They have completed a total inventory of all collec- tions in the Arboretum based upon a grid layout on 100 foot centers. For the first time, Arboretum staff have a standardized system for mapping and conducting inventories of the collection. This is also the first, complete inventory of the Arboretum. The Arboretum will be employing a unique and original application of computer software for this project known as a Geographic Infor- mation System, or G.I.S. The G.I.S. system will manage the geographic data in conjunc- tion with our plant records data to produce detailed and/or analytical maps of Ar- boretum features. The electronic future is upon us!
