Tree Inventories : In the Palm of Your Hand

By Dr. David V. Bloniarz, Shaun V. Phelan, M.Ed. and Dr. H. Dennis P. Ryan Introduction Until recently, the collection of tree inventory data has involved the use of expensive hand-held computerized data recorders or simple paper systems to record information on the type, size, condition, health, and maintenance requirements of public and private trees. Whether one was inventorying trees growing along public streets, on private property or in recreation areas such as golf courses, collecting and managing the information required equipping inventory personnel with hand-held data recorders costing thousands, or involved costly data entry once the field work was completed. Today, low-cost solutions to field data collection and storage needs are available, using Personal Digital Assistants, or PDA’s, collectively referred to as Palm Pilots. These hand-held devices are inexpensive, easy to use and A personal digital assistant (PDA) provides a low-cost alternative to more expensive systems for collecting data on public and private trees. Many PDA programs are available for use by arborists and tree managers.
