We continue to expand the yield projection capabilities of the Tree and Stand Simulator (TASS) through the addition of the two broadleaf species, trembling aspen and paper birch. We have also enhanced TIPSY through the development of a variable retention (VR) harvesting simulation system. The addition of VR to TIPSY, will be widely distributed to forest practitioners during 2004. These enhancements will also position TASS and TIPSY software for future modelling of mixedwood and complex stand partial harvesting prescriptions and integration with other research into root disease and wildlife habitat. The expanded capabilities of our system of models will continue to provide new information in support of decisions related to silviculture prescriptions and timber supply planning.
