Developed at the University of California, CACTOS is designed to model the changes that take place in young-growth conifer stands in the mixed conifer regions of Northern California. It requires the user to enter a stand description and allows students to perform various operations and print out various descriptive reports relating to the stand. It has an enhanced set of prediction equations for more accurate growth projections. Also has an on-line tutorial running in a second window. This program allows for the customizing of reports through its interface with "write" or "note pad" commands.
The primary purpose of CACTOS is to predict yields to alternative harvesting practices.
