An illustrated booklet and hypertext database are being developed to help students registered for various plant science courses locate and identify woody plant species on the Iowa State University (ISU) Campus. Of the 300 species of plants listed in the Botany 356 (Dendrology) course, 100 species growing on Campus were selected for inclusion in this project. The booklet and hypertext database are, however, specifically designed to cater to a broad audience, including current and potential students in the plant sciences, the general student population, faculty, staff, alumni, visitors and the home-landscaper. The booklet is designed to provide a self-guided, walking tour of 100 species of trees and shrubs of ISU Campus. Description of each species includes: (1) a detailed map indicating the location of the plant on Campus; (2) pen-and-ink drawings of important identifying characteristics; and (3) text information about the identification, distribution, ecology and uses (wood, wildlife and horticulture). The on-line hypertext database integrates color photographs (specimens on Campus, leaves, flowers, fruit, bark, habitat, uses) and text information to provide a comprehensive, "virtual tour" of these 100 species. These two forms of presentation-the paper-based "field guide" booklet and the multidimensional hypertext database-are designed to complement one another to provide a valuable educational resource utilizing the wealth of mature specimens of both native and exotic trees and shrubs on the ISU Campus. A CD will be developed to include a general pictorial survey of the ISU Campus, and the on-line hypertext database. Both the CD and the booklet will be available as a single package.
