TIPSY is a growth and yield program that provides electronic access to the managed stand yield tables generated by TASS and SYLVER. TIPSY retrieves and interpolates yield tables from its database, customizes the information and displays summaries and graphics for a specific site, species and management regime. Yield tables are available for various even-aged coniferous species, as well as trembling aspen and red alder, growing on the coast and in the interior of British Columbia.
