The Carbon Budget Model of the Canadian Forest Sector (CBM-CFS3), version 1.2, described in this user’s guide, was developed to meet the operational-scale forest carbon accounting needs of forest managers and analysts across Canada. The CBM-CFS3 is a stand- and landscape-level modeling framework that can be used to simulate the dynamics of all forest carbon stocks required under the United Nations Framework Convention on Climate Change and the Kyoto Protocol. It is compliant with the carbon estimation methods outlined in the guidelines of the Intergovernmental Panel on Climate Change. The model uses much of the same information that is required for forest management planning activities (e.g., forest inventory, growth and yield curves, natural and human-induced disturbance information, forest management schedule, and land-use change information), supplemented with information from national ecological parameter databases. With this sophisticated but user-friendly software tool, users can apply their own stand- and landscape-level forest management information to calculate carbon stocks and stock changes for the past (monitoring) or into the future (projection). Users can also create, simulate, and compare various forest management scenarios to assess impacts on carbon. Tools supplied with the model assist users with importing required data from common timber supply models or from user-developed data files. The model contains tools to help prepare data, define scenarios, perform analyses, and examine results. Results of analyses can be used for various types of forest ecosystem carbon reporting requirements. Although the model currently contains a set of default ecological parameters appropriate for Canada, these parameters can be modified by the user, which allows for the application of the model in other countries.

Plain Language Summary

Many researchers, forest managers, governments, and non-government organizations want to use the Carbon Budget Model of the Canadian Forest Sector (CBM-CFS3) computer model to calculate how much carbon is in their forest trees and soil and how much carbon is released to the atmosphere from their forests every year. This report describes the basic utility of all of the tools within the CBM-CFS3 software. It shows people how to create projects for a single forest stand, or use the model for the forests across provinces, or the entire country. For example, it explains the basic information and data needed to create a project in the CBM-CFS3, how to modify a project once it is created, how to execute project simulations, and how to view forest carbon stock or stock change results for a simulation. By using the CBM-CFS3, users can determine, manage, make decisions about, and report on the carbon contained in their forests and how these carbon stocks will change over time.
