What are the current limitations of the CBM-CFS3?
Peatland carbon dynamics: Although forested peatlands are recognized as an important contributor to carbon stocks in Canada, little is known about the impacts of management, disturbances, and climate change on fluctuations in water tables. Without the ability to predict changes in the water table for records in the peatland component of the forest inventory, it is not possible to predict the associated changes in carbon stocks in the peat component of the system. This issue is the subject of ongoing research. For example, for some boreal black spruce stands on peatlands, the model simulates the forest component of the ecosystem, but does not address the dynamics of the peat layer or the contribution of mosses to peat formation. Climate change impacts on forest growth: The CBM-CFS3 can simulate the effects of temperature changes on decomposition rates (Kurz and Apps 1999), but it does not address the impacts of changes in precipitation on decomposition. It also does not address the impa
