Initiatives such as the Kyoto Protocol, the Canadian Council of Forest Minister?s Criteria and Indicators (adopted from the Montreal Process), and forest certification have required forest managers to address sustainable forest carbon management. The purpose of this project is to provide an initial estimate of the current carbon condition and forecast (over a 250-year period) in aboveground and belowground biomass in trees for the Nimpkish Defined Forest Area (DFA). This preliminary analysis utilizes biomass expansion factors, which are basic equations and conversion factors to estimate total tree carbon for estimating roots, and a. A ?base case? was defined using current management and harvest assumptions, as outlined in the recent timber supply analysis in the Nimpkish Defined Forest Area (DFA) (further information can be found in the Tree Farm Licence 37 Timber Supply Analysis Report for Sustainable Forest Management Plan). Under the base case, the current tree carbon storage is estimated to be approximately 33.13 megatonnes (MT) and may decrease to a low of 25.98 MT over a 250-year forecast horizon. The decline in tree carbon storage is related to the declining growing stock predicted for the base case. The sequestration rate in the base case scenario also fluctuates between a net loss of 0.45 MT C/year and a sequestration of 0.11 MT C/year. The preliminary analysis of tree carbon in the Nimpkish DFA provides an initial estimate and possible ranges in tree carbon over time. Although the general flux in carbon pools in a forest ecosystem is the greatest in trees, it is important to also consider the entire forest ecosystem carbon which also includes carbon in soils, deadwood, litter and other vegetation such as in shrubs and mosses. The results of this project are preliminary for the Nimpkish DFA and as such, it is recommended that a comprehensive carbon analysis be considered. This would include forecasting of all carbon pools, the use of the most up to date forest inventory and other natural resources data, and the consideration of natural disturbance impacts on forest carbon in both the timber harvesting and non-timber harvesting land bases.
