An urban forestry program in Windsor, Ontario, focuses on the planting and maintenance of a permanent canopy of street and park trees. Diversification of the tree population has resulted from an emphasis on the use of native tree species, together with various management techniques.

A split-screen, main frame computerized tree information system has been developed in Windsor, Ontario, to integrate a manual tree inventory and work record system with a manual current work order system. The computer system provides tree information such as diameter, height, tree condition, location, origin year and survey year, for individual municipal addresses. This information is shown on a tree inventory file which is linked to the current work order and work history file. Simplified parameters were utilized for easy updating and information retrieval by municipal staff. A tree code was developed using a genus/species four-letter code from common tree name abbreviations. Tree locations were indicated by a floating tree ordering system in relation to the curb and position on the property, rather than using coordinates for each tree. The parameters provided on the tree inventory file allows the sorting of data to produce tree profiles by planning districts. Management of the tree population is thusly upgraded, enhanced, and systematized.
