Abstract

A computerized growth and yield model based on a variable density stand table projection system using 1-inch-wide diameter classes has been developed for projecting expected stand conditions in southwestern mixed conifer and ponderosa pine stands, including the effects of dwarf mistletoe. Stand management options include both even-aged and uneven-aged cutting methods.
