Halli, R. A. A. Oldeman, and P. B. Tomlinson, Tropical Trees and Forests: An Architectural Analysis (Berlin: Springer-Vedag, 1978). jectively sorts things (baggage, trees) into recognizable groups based on whether or not they have specific features. It also contrasts with the tree architecture approach, which is based on one narrow aspect of arboreal biology-bud arrangement-but does not address subsequent growth dynamics in real environments. Each has its value, however. One of my computer science colleagues, ]udy Cushing, and I have been working to develop a new and integrative conceptual framework to categorize trees, What Is a Tree?

FOREST AIRSPACE Until recently, structural classification systems focused on the arrangement of solid objects within a forest-the trees, stems, and foliage. But recent work has involved measuring the "negative space" as well, that is, the volume not occupied by solids. Dr. Roman Dial, a fit, bearded researcher from Alaska Pacific University who completes triathlons as easily as he writes database routines, quantitatively describes the airspace of world forests in order to better understand their structure.

And doesn't he picture his thoughts springing From moss and decay, from the white sponge Of fungus and porous toadstools blending? He is shaped by the fecund and the damp, His fertile identifications with humus And the aroma of rain on the deepening Forest floor. Seeing the sky only in pieces Of light, his widest definition must be modeled After the clearing hemmed in by trees. - Pattiann Rogel'S, "The Determinations ofthe Scene" My knowledge of the shapes and forms of trees is incorporated into the muscles and skinned knees of my youth, growing from my schoolgirl afternoons climbing maple trees in our front yard.
